• Last week we had our first coordination meeting. While we are still collecting the minutes, here is a summary of the actions decided to be taken by the general coordination based on the discussed topics:
1. The general coordination will engage with each thematic area coordination separately to discuss its specific needs, progress and strategies;
2. The general coordination will engage in proposing entries to the entry list of each thematic area, by going through publication in optics related the thematic areas and sourcing relevant terms and concepts;
3. The general coordination will start creating a few stubs (one paragraph articles) per week, to help exemplify the concept an entry is expected to encapsulate, while also providing initial suggestions of symbols when relevant. This should help to create other articles that use those concepts and symbols.
• Curtis Mobley has started adding some content to RHON. Since he will add a lot of content in the optics thematic area, Alex will be aiding him in the formating of the articles. First articles recently created by Curt are: Absorption coefficient, Absorption (electromagnetic radiation), and Speed of light. The focus at the moment is to add content, and slowly fine tune the structure and content over time – all welcome to contribute, of course.

Wiki:

• The Synonym template now also allows to define the scientific field that uses a given synonym and a comment on why the synonym is not recommended/used in RHON.
• The New article template was moved to New article quantity, but a redirect was left behind such that you can still either {{subst:New article}} or {{subst:New article quantity}} will give the same result when creating a page. We plan to create the template New article process to be used with articles such as Absorption (electromagnetic radiation), but the content style is still in development.
• The optical articles should be written in vector form when dealing with quantities that have polarization. The scalar approximation should be added to a subpage. For example, the Glint article is now defined in terms of the Stokes vector, but there is a link to the page Glint/scalar that presents the same definition with a scalar approximation (radiance).

Who we are

The GEO AquaWatch Nomenclature Focus Group is a community-lead initiative to harmonize and make accessible the terminology in hydrologic optics and aquatic remote sensing. It is hosted by GEO AquaWatch and has support of IOCCG. As a focus group, it has limited duration and is expected to be active from August 2022 to August 2024. As of January 2023 it has more than 70 members from a diverse set of specializations, institutions  and nationalities.

It is a volunteer-based effort organized over a variable number of thematic areas and overseen by a general coordination. The two general coordinators are Alexandre Castagna and Daniela Gurlin. The thematic areas currently active and their respective coordinators are presented in detail in the section thematic areas.

The group is open to community members that wish to collaborate with the effort. It is possible to join the effort at any stage stage of the project development. To join the focus group, send an email to Alexandre Castagna and Daniela Gurlin.

Motivation

Hydrologic optics and aquatic remote sensing are multidisciplinary research areas, often with research groups working within a limited scope but nonetheless dependent on concepts, methods, and quantities from the broader scope encompassing these research areas. For example, concepts of engineering, atmospheric optics, meteorology, statistics and radiative transfer are necessary for robust aquatic remote sensing application and interpretation. Knowledge about phytoplankton pigmentation groups, ecology, genomics, statistics and optical processes is of relevance when considering absorption-based algorithms and their application to phytoplankton diversity. Connecting and leveraging the developments in the different areas requires an accessible and common language.

Jargon exists to simplify communication, but can also act as a barrier when it does not adequately (or intuitively) capture the concept it is intended to encapsulate. For example, as knowledge evolves, nomenclature may need to be updated to better reflect current understanding. It also seems the case that at least some nomenclature was created without special attention to existing terms in related fields, or care about its specificity (e.g., ‘anomalous diffraction’), or objective definition (e.g., ‘optically shallow’). It is also the case that some definitions or terms vary between research groups / traditions, or are currently evolving in the literature. It is also encountered that some terms referring to theoretical definitions are indiscriminately applied to measured quantities, despite the known departure from definitions (e.g., attenuation and scattering coefficients). Even if none of those were issues, the terms and definitions we interact with are not concisely and systematically collected in a reference document.

Objectives

The main objective of the GEO AquaWatch Nomenclature Focus Group is to provide a free and accessible authoritative terminology reference that can facilitate communication between researchers with different specializations and experience within the field, researchers from closely related fields and stakeholders (institutions, agencies, etc).

The agreed upon key features of a deliverable addressing this objective are:

• Authoritative: accurate, rigorous, community consensus, and endorsed by major hydrologic optics and aquatic remote sensing institutions or organizations;
• Comprehensive: include a broad selection of terms and concepts encompassing the multidisciplinary research field and closely related research areas.
• Focused on interpretation: provide clear links between theoretical and measured quantities, provide information on range of observed values in natural environments, and other information that improves the interpretation and use of measured and estimated quantities.
• Online and free: for easy access, low cost of production and distribution, flexible downloadable or printable.
• Citable: provide support for articles and projects, not needing to define terms and symbols, but point or link/embed directly the content.
• Promote and facilitate use: provide enhanced user interaction such as the export of equations and symbols in vector format, LATEX code, API for synonyms and data conversion, etc.
• User friendly: provide an intuitive interface for authors, editors and readers, use an accessible color scheme when considering color vision deficiency, potentially include a programming interface, among others.
• Machine readable: enable semantic web applications.
• Built with expansions in mind: for example, multi language support.

Based on the above objective and key points, the Nomenclature Focus Group will produce and curate a version-based online encyclopedia, powered by the MediaWiki software and its Semantic MediaWiki extension. Content creation, editing and reviewing, will be restricted to the Nomenclature Focus Group members. The wiki will be available from www.aquatic-optics.science.

Timeline

The overview of the agreed upon timeline of the project is provided below.

Code of conduct

The Nomenclature Focus Group will follow the same code of conduct adopted by GEO AquaWatch (in preparation). The document will be linked here when available.

Thematic areas

To better organize the effort, the Nomenclature Focus Group is subdivided in thematic areas proposed by its members. The list of thematic areas and coordinators is provided below:

To join a thematic area first you need to be a member of the Nomenclature Focus Group. To join the focus group, send an email to Alexandre Castagna and Daniela Gurlin. As a member you can edit the thematic area membership file by adding your name to the desired thematic areas.

Resources

The main resources used by the group are a mailing list and a shared folder for administration and planning. The content under production is contained in a private wiki that will be published with the release of version 1. Some of the relevant documents are available here:

Previous news

Week 026: 15/02/2023 to 22/02/2023

Exceptionally, this week no communication was sent.

Week 025: 08/02/2023 to 15/02/2023

This week we welcome:

• Emmanuel Boss from UMaine (US); {optics, biology, geology}
• Margaret Estapa from UMaine (US); {chemistry}

• Juliana Costi has taken up a coordination role in the Geology/Physical oceanography thematic area together with Sorin Constantin. Thank you Juliana for volunteering for this role! Now, all of the current thematic areas have two coordinators, and for most it was possible to follow the inclusive principles we had established for the coordinations. This is thanks to Daniela Gurlin’s work communicating with members to find volunteers.
• It has been 6 months since our first plenary meeting, back in August last year – thanks to all that have agreed that this was an important initiative and that have stepped up to help make it real.

Info:

• Coordinators (with input from members) are drafting the list of entries to be curated by each thematic area. We had an initial timeline to have it completed by the end of november, but since the coordinations were not fully formed yet, we have relaxed that deadline. Nonetheless, the drafting of the list of entries is very important to start the work. Each thematic area is now hosting its list on its page, all accessible from the main page of RHON. Sources for those entries are reference works listed in the reference list, among other external sources. All members can contribute! Send you suggestions to the thematic area coordinators.
• We have some open threads in the mailing list: (1) the request for volunteers to translate the R code example to use TikZ with Matlab and Python; and (2) for the optics thematic area, on thoughts on how to provide vector and scalar versions of symbols and equations (sub page with separate set of semantic properties or just add additional semantic properties to the main article page to register scalar or vector symbols?).

Wiki:

• It is great to see that some members are starting to explore the wiki. Samantha Lavender and Igor Ogashawara made their personal pages, and Sam has also started to draft the signal-to-noise ratio page. Daniel has tested out new pages putting the skeletons up for Modulation Transfer Function and Relative Spectral Response. And the coordinators of the Earth observation and Geology thematic areas are adding information to the draft list of entries in their thematic areas.

Week 024: 01/02/2023 to 08/02/2023

This week we welcome to the group:

• Bruno Palmerini from USherbrooke (CA); {optics, biology}
• Eva Álvarez from OGS (IT); {optics, biology, chemistry}
• James Fox from OSU (US); {optics, biology}
• Kevin Turpie fom UMBC (US); {optics, biology, Earth observation}
• Mariano Bresciani from IREA/CNR (IT); {optics, biology, Earth observation}
• Sasha Kramer from UCSB (US); {optics, biology, Earth observation}

• Some members reported issues login in for the first time in the wiki. Note that credentials were sent by email (check your spam folder) and the temporary password has an expiration date – if you haven’t logged in and changed your password within a few days since your account was created, send an email to Alexandre Castagna (a password retrieval email will be send to you).
• If you would like to develop an entry, send a message to the coordinator of the relevant thematic area.
• In two weeks we will have a coordination meeting and it will be important to have feedback from editors in their experience using the platform. If you have a suggestion of a topic to be discussed in the coordination meeting, please let us know. The coordination meeting involves only the general coordinators and thematic area coordinators, though we will address and discuss several aspects of how to coordinate the effort and how to better use/setup the platform.

Wiki:

• We have created a function to correctly format authors’ names (e.g. “Mobley, C.” instead of “Curtis Mobley”) and this function is now used in all automatically generated references. This should fix all the reference lists to the appropriate format.
• The “Cite this page” link has been updated to present the reference to a page in the format of a book chapter of an edited multi volume book series. For example, the glint entry will generate the following bibtex entry:
 @incollection{RHON:Glint,
author    = "Alexandre Castagna",
title     = "Glint",
year      = "2023",
editor    = "Agnieszka Bialek and Curtis Mobley"
booktitle = "Optics",
volume    = "1"
series    = "Reference Hydrologic Optics Nomenclature \textup{(Alexandre Castagna and Daniela Gurlin, series editors)}",
edition   = "1st",
publisher = "GEO AquaWatch",
annote    = "http://www.aquatic-optics.science"
}

Which in APA style will render as:
Castagna, A. (2023). Glint. In Bialek, A., Mobley, C., editors, Optics, volume 1 of Reference Hydrologic Optics Nomenclature (Alexandre Castagna and Daniela Gurlin, series editors). GEO AquaWatch. http://www.aquatic-optics.science.
Let us know if you have any suggestions on this!

Week 023: 25/01/2023 to 01/02/2023

This week we welcome:

• Clémence Goyens from RBINS (BE); {optics}
• Isabel Brandão from NIOZ (NL); {biology}
• Juliana Costi from UBordeaux; {geology}

Wiki:

• We have created a workaround to add citations to figure captions, with the new function {{CiteImg|CitationKey}}. The page Manual:Citations and the cheatsheet were updated to include this function.
• During the workshop we rendered equations with the math tags $…$ because it was the simplest approach, but this is not the preferred approach. The reason is that we want to define variables in one place and use them anywhere, so instead of entering the symbol of a variable in the equation, the best approach is to query for this symbol. The function to do such a query retrieving the TeX markup is {{Sm}} (“Symbol markup”). The problem with the math tags is that they will not perform variable expansion, so to use the {{Sm}} function we need to use the parser function {{#tag:math|…}} instead of the tag. The Manual:Formating#Rendering equations section and the cheatsheet were updated to include this. See examples in the example article, Glint.
• To make inline use of symbols simpler, the function {{Sd}} (“Symbol display”) was augmented with two extra arguments that receive markup to prepend or to append. For example, to render the symbol for wavelength in vacuo (LaTeX: $\lambda_0$) one would use {{Sd|Wavelength|_0}}. See examples in the example article, Glint.
• All manuals are ready and accessible from the main page of the wiki.

• We are transferring the draft list of entries from the shared folder directly to a table in each thematic area pages in the wiki. All members can contribute with entries to those tables, but we expect the coordinators to set the priority values.

Week 022: 18/01/2023 to 25/01/2023

This week we welcome:

• Sorin Constantin from Terrasigna (RO); {geology/physical oceanography}

• Sorin Constantin has taken up a coordination role in the Geology/Physical oceanography thematic area. Thank you Sorin for volunteering for this role!
• This wednesday we had our workshop on our MediaWiki installation – the recording should be available soon and we will send a message when it is in our shared folder. Thank you for all that joined – we think it was an interesting session, made all the better with your questions at the end! Take your exploration steps, check the manuals and of course write to the general coordination in case you have doubts or issues.
• Some members have reported issues when logging in to the platform. This was solved by the coordination sending a password recovery email to the editor – it is possible that this issue arises from an expiration date for the temporary password that was sent to you when the account was created. If you haven’t already logged in for the first time, please do so shortly. If you face any issues send an email to the coordination.
• In about a month we will have the first coordination meeting with the general coordination and the thematic area coordinators. The idea of this meeting is to discuss the first experiences using the platform and draw strategies for progress in content production. Would all the more informative if members try out the platform and start drafts to point out what needs to be added or improved.
• In the project page of the wiki, we have a thread to request new features (functions, new page templates, etc) and to report issues and errors: RHON talk:Project.
• We also have a table with the state of development of all features requested by editors or described in the deliverable specification: RHON:Project#Roadmap.

Week 020: 04/01/2023 to 11/01/2023

This week we welcome:

• James Goodman from HySpeed Computing LLC (US); {benthic habitats}

News:

Next week we plan to start creating the editor accounts in our wiki. In the deliverable specification, it was proposed that usernames (=login) will follow the pattern as in the example below:

Real name: Alexandre Castagna

The number in the username is the editor’s ORCiD. The justification is presented in the document. The real name is desired to provide the automated page citations, while the pattern for the user name is to help with possible name ambiguity. Internally, all links related to the editor will be displayed as: Real name (username).

Therefore the coordination needs to receive your ORCiDs. The thematic areas membership file now has an additional sheet listing all members, with a column to add the ORCiD. We ask that all members of the NFG add this information before the workshop date, January 25. If for any reason a member has opposition to ORCiD, please contact the coordination.

• Daniel Maciel has now joined Samantha Lavender in the coordination of the Earth observation thematic area. And James Goodman has now joined Heidi Dierssen in the coordination of the benthic habitats thematic area. Thank you Daniel, Sam, James and Heidi for volunteering for this role. It is also very fortuitous that the NFG can have synergies with the IOCCG working group Conducting Benthic Reflectance Measurements!
• Attached to this email are some screenshots of our wiki in development (those examples are not final). We hope the tease keeps you all motivated while we work to finish setting it up:
1. An example of a user page (personal sandbox), with a personal infobox populated with semantic properties about the editor that can be potentially used in different layouts (e.g. adding a picture of the main authors in the bottom of an article);
2. An example skeleton of a content page (quantity type). All displayed information on the infobox and synonym table are queried from assigned semantic properties (in fact, the specification symbols are queried directly from the pages of the independent variables).
3. An example for page A of our reference manager. References are registered as semantic properties imported from bibtex entries. Inline citations based on the citation key are automatically gathered in a references section at the bottom of a content page.
4. An example of the manuals we are writing, showing in this case how to display formulas and symbols.

Week 019: 28/12/2022 to 04/01/2023

We hope you all had great end of year celebrations. In this small area of our lives, 2023 looks bright with our platform ready and editors eager to add content. We are really happy about how the project has developed so far and really excited with the prospects for this year. Thank you for the participation and for the support to this project. We are in the countdown to launch the editor portal of the wiki!

• The optics thematic area coordination is now complete with Agnieszka Bialek joining Curtis Mobley. Thank you Aga and Curt for volunteering for this role!
• The poll to select the date for the hands-on workshop is now closed. The selected date is January 25, 19:00 to 20:30 (UTC). A calendar invitation will follow shortly.

Week 018: 21/12/2022 to 28/12/2022

Hope you all had great end of year celebrations so far – some more celebrations coming our way this weekend 😉

• The biology thematic area is now coordinated by Áurea Ciotti and Igor Ogashawara! Thank you Áurea and Igor for volunteering for this important coordination position, we are very excited for the work of this group. On a side note, we are still looking to complete the set of coordinators of all thematic areas: optics, geology/physical oceanography, benthic habitats and Earth observation. Please send an email to Daniela Gurlin if you are interested in helping to coordinate activities for those areas.
• We have an installation of MediaWiki working at https://www.aquatic-optics.science. Alexandre Castagna is currently testing several aspects of it and writing some manual pages to help get going with the basic editing activities. The login credentials for members of the Nomenclature Focus Group will be provided after the hands-on workshop on our MediaWiki installation.
• The final draft of version 1 of the deliverable specification document will be completed by the end of the week. Samantha Lavender volunteered to review this document in the first weeks of January.
• We had 11 answers to the poll about the best date for the hands-on workshop. The best candidates so far are January 24, 25 or 30. Please add your votes by next Wednesday, when we will announce the date for the workshop.

Week 017: 14/12/2022 to 21/12/2022

We did not send the info weeks for the weeks 015 and 016 as activity in the group was low and Alexandre was mostly absent from the NFG coordination. Now we are back with our weekly information on the progress of our group.

This week we welcome:

• Norman Nelson from UCSB (US) {optics,chemistry}

• We were awarded by GEO AquaWatch funds to acquire a domain and shared hosting service. The purchases were made this week with help of Steven Greb and we are setting up the MediaWiki system. The wiki will be accessible through: https://www.aquatic-optics.science
• We will conclude the first version of the deliverable specification document by the end of the month. The coordination appreciates the help and comments provided by Sam Lavender.
• We are organizing a hand-on online workshop on editing in the MediaWiki environment. We will develop in real time one example entry, in steps. We will cover the basics from login, to creating pages, formatting text, adding equations, adding images, and how to use the resources for collaboration such as talk and discussion pages. We sent out a doodle with options in the second half of January, with the proposed time of 19:00 to 20:30 UTC.

Week 016: 07/12/2022 to 14/12/2022

Exceptionally, this week no communication was sent.

Week 015: 30/11/2022 to 07/12/2022

Exceptionally, this week no communication was sent.

Week 014: 23/11/2022 to 30/11/2022

Thanks for all that send some recommendation of researchers in optics/chemistry interaction to be invited to the group. If you have more recommendations you can send to me and Daniela either privately or in the group.

• We had defined the end of November to be our deadline to complete the first version of the deliverable_specification document. However, considering the importance of this document, the need to further discuss some aspects of it, and the likelihood that we will only start the content creation phase in January, we are extending the deadline to conclude the first version of the specification to the end of this year.
• We have created a type a gantt chart for our milestones to help all navigate or understand the evolution of the project. This document will be updated to give more resolution (whenever we break down a milestone in “sub”milestones).

Week 013: 16/11/2022 to 23/11/2022

Thanks for all that could attend the presentation on the Semantic MediaWiki today. Soon the link of the video will be made available to others in the group that could not join and are interested in knowing more about the platform.

I have prepared a distilled summary below of what MediaWiki and Semantic MediaWiki are (in my understanding) and why I think they are the platform of choice for our deliverable. If you have any questions, general or very specific, or would just like me to elaborate more, please send a message to our mailing list.

We will have a hands-on session where we will show the actually very simple interface to write content to the platform (or copy and paste from your own computer).

Summaries:

Week 012: 09/11/2022 to 16/11/2022

This week we welcome:

• Ariel Blanco from PhilSA / EnviSAGE (PH)
• Claudio Barbosa from INPE (BR)
• Mariana Soppa from AWI (DE)
• Philipp Saile from GEMS / ICWRGC (DE)
• Tadzio Holtrop from PlanBlue (DE)
• Vitor Martins from MSState (US)

• Next week we have the presentation about the Semantic MediaWiki by Bernhard Krabina, November 23, 15:00 to 16:00 UTC.
• The minutes of the 2nd plenary meeting are online for review. To further help new members to better understand the initiative, the recording of the 2nd plenary meeting will be available for the next few weeks.
• Don’t forget to review / contribute to the draft of the deliverable specification. It is open for contributions until November 30. Please add those contributions as comments or edit the document with the option “suggesting” (set the drop down menu at the upper right corner).

Week 011: 02/11/2022 to 09/11/2022

This week we welcome:

• Daniel Maciel from INPE (BR);
• Dariusz Stramski from UCSD (US);
• David Antoine from Curtin (AU);
• Hà Nguyễn from VNU (VN);
• Janet Anstee from CSIRO (AU);
• Nathan Dryason from CSIRO (AU);
• Salem Ibrahim from KUAS (JP);
• Shenglei Wang from RADI (CN);

• The draft of the deliverable specification is open for receiving contributions until the end of November for a first version. Please add those contributions as comments or edit the document with the option “suggesting” (set the drop down menu at the upper right corner). The idea is to document how and why the deliverable will function and it contains the base propositions brought up by the coordination in the last meeting. Some of the topics, as a citation model, needed some further discussion. Some more technical aspects of the document, relating to implementation in MediaWiki are in early draft stage and will be evolving fast the next few weeks. Unless you are interested in the mechanics of MediaWiki, you can ignore those parts.
• The coordination would like to thank all members that send suggestions of researchers that we should reach out to, with special attention to researchers in institutions from countries or geographic regions that are underrepresented in this group. In total, 34 invitations have been sent since the meeting last week.
• We have decided to test a simple method for thematic area communication. To indicate that a thread is sent to the members of a specific thematic area, members creating the email thread are requested to add the group prefix to the subject line as “GXX: “, where XX is the two digit group number as defined in the thematic_areas_membership file.
• Samantha Lavender is now coordinator of the Earth observation thematic area. We are looking for another volunteer to share the coordination with her.
• Tristan has started an entry on polarization discovery, as part of the historical notes thematic area.
• Daniela Gurlin is making the careful work of writing the minutes of the 2nd plenary meeting. This is the reference document and will be available by the end of this week, but a summary is provided below.

Summaries:

• We would like to thank all that participated in the 2nd plenary meeting last week. Due to special circumstances or time zone constraints not all members could join and we also appreciate the communication and suggestions we received from those.
• An evaluation of the progress since the first meeting showed that we are mostly on track, though we are behind in: prototyping (producing one or two example entries per thematic area), on listing entries (concepts, quantities, methods) that will be curated by each thematic area, and on having filled coordination positions in all thematic areas. Currently optics, benthic habitats and Earth observation have only one coordinator each and biology and geology have no coordinators – any volunteers in the group? We have a draft document describing the coordination positions. The example entries are very important for us to have a clearer view of the format/structure of the entries.
• We have proposed a citation model to address concerns by the members on attribution and recognition for the volunteer work. Essentially each entry could be cited individually, with authorship automatically listed if so desired. This is detailed in the deliverable specification.
• We have also proposed a production model to separate the technical aspects of managing the information, creating texts, figures, etc. In essence all members need to at least upload text to the platform, with figures and graphics, markup language and semantic annotations added or harmonized by specific groups. This is detailed in the deliverable specification.
• And we will work on a joint publication describing this initiative. We will start this document once we have more concrete definitions/specifications of the deliverable.

Week 010: 26/10/2022 to 02/11/2022

It has been 2.5 months since our first meeting, at the end of August. We took a very important step in starting this community resource and harmonization effort, drawing the general lines of what we want to achieve and sketching a plan on how to achieve it. We have since worked to add some more strokes to the sketch, studying models (infrastructure, work division, citation) that would fit with our vision and constraints. Tomorrow we will have the opportunity to discuss those in more detail.

We have also worked to make the broader community aware of this effort and to bring new members to the group, advertising it in meetings, sending direct invitations, and preparing the website. At the same time, we have structured ourselves further, with thematic areas and thematic area coordinators that volunteered to help organize the effort. Topic discussions have also started in our mailing list with interesting propositions and perspectives, and draft documents capturing those ideas. And we have gained important support from individuals/institutions with knowhow on the type of infrastructure we need to bring this project to life.

We have much to do, but I believe we are on a good track.

Week 009: 19/10/2022 to 26/10/2022

This week we welcome:

• Barbara Bulgarelli from JRC (IT);
• Chuanmin Hu from USF (US);
• Rabia Khan from SYR (US);

• The final agenda for the second plenary meeting is available. The meeting takes place next week, November 3. We have adapted it considering the current material available from the thematic areas and added an important discussion on publication / citation models. Since we have many new members, we will also present an overview of this focus group;
• We have started a draft with the list of entries organized by thematic area;
• Our group has grown to over 50 members over the last two months, with a diversity of expertises and affiliations! We believe this diversity and scale are important for a community-driven resource, and for its actual adoption into our lexicon.

Week 008: 12/10/2022 to 19/10/2022

This week we welcome:

• Martin Ligi from UT (EE);

• As you now know from the calendar invitations we sent last week, we will have a presentation about the Semantic MediaWiki software as a potential alternative of infrastructure for this project. Semantic MediaWiki is a semantic web extension to the MediaWiki (software that runs Wikipedia). The meeting will take place on November 23.
• We have updated the organogram;
• And started a draft document on the roles within the NFG: roles.

Notes:

• We are two weeks away from our next meeting and we are still needing to have some example entries from the thematic areas;
• We are also needing to get the list of terms concepts that each thematic area will potentially curate.

Week 007: 05/10/2022 to 12/10/2022

This week we welcome:

• Agnieszka Bialek from NPL (UK);
• Alexandre Corizzi from LOV (FR);
• Samantha Lavender from Pixalytics (UK);

• We received a lot of positive feedback on the strategy for the invitation of co-coordination of the thematic areas. Most thematic areas have at least one coordinator, except biology, geology and Earth Observation. Any one of those groups willing to have at least for a time a coordination role?
• At the FAR-2 workshop in Belgium we had some interesting discussions on nomenclature two, pointing out some problems with the concept of BRDF correction, when it is actually a hemispherical-directional (or conical) correction.
• We got a representative of the Semantic MediaWiki o give a presentation for our group. It will be a presentation 23 or 24 of november. Soon we will send an invitation.
• Alex Castagna started a draft for an entry of the optics thematic group wich is open for comments before presentation on our next meeting: glint.

Week 006: 28/09/2022 to 05/10/2022

This week we welcome:

• Abhishek Kumar from UMASS (US);
• Deepak Mishra from UGA (US);
• Hongyan Xi from AWI (DE);

• We have sent out invitation emails to selected members of each thematic area to act as coordinators. While we welcome all volunteers, for our invitations we have tried to follow the some guidelines: (1) invite two members of each thematic area to share the coordination; (2) have female and male leads; (3) combine early and senior career scientists; (4) cover geographical regions (funding, agencies, regional communities); (5) cover different niche expertises inside a given thematic area.
• As suggested by Tristan, we have added a new thematic group: historical notes. The idea I believe would be to work adding historical perspectives to entries that do not have them yet or expand existing ones. It was added to our thematic areas file.
• Ils Reusen has sent us the Water-ForCE glossary (V1) – it is now in our reference folder and an entry was added to our reference list.

• Robert Frouin proposed to organize within the group a paper focused on the nomenclature for reflectance in hydrologic optics / aquatic remote sensing. This could be a great way to get us started.

Week 005: 21/09/2022 to 28/09/2022

This week we welcome:

• Guillaume Morin from INRAE (FR);

• The minutes from the first meeting we prepared by Daniela Gurlin last week. You are welcomed to read this document and to suggest addition or change of content.
• We have also sent emails this morning to all thematic areas that do not have a coordinator with the goal of choosing coordinators and organizing the work in each thematic area. We have about one month until the next meeting and the more groups present example entries the better will be the results of the meeting.
• Finally, we have invited the coordinator of the Semantic MediaWiki, a project that extends the MediaWiki (the software powering Wikipedia) with semantic web standards, to give a presentation to our group or to suggest another presenter. We are still waiting for a reply. Alex believes that the Semantic MediaWiki could be the best solution for cooperative content creation incorporating semantic web. Any other suggestions are welcomed.

Week 004: 14/09/2022 to 21/09/2022

This week we welcome:

• Emanuele Organelli from ISMAR (IT);
• Jaime Pitarch from ISMAR (IT);
• Thomas Jordan from PML (UK);

We will communicate with the subgroups of different thematic areas this week to select a coordinator.

Week 003: 07/09/2022 to 14/09/2022

This week we welcome the new members:

• Bozena Wojtasiewicz from CSIRO (AU);
• Caren Binding from ECCC (CA);
• Marco Talone from ICM-CSIC (ES);

• For the members that had not filled the thematic_areas_membership file, we have added their names to thematic areas they might be interested in as a suggestion – please do check and update the thematic area sheets accordingly. The coordination of each group will be defined by its members. Temporarily we have Curt on the optics group and Heidi in the benthic habitats group – they have volunteered to start the work and may continue as coordinators depending on their availability and group evolution.

Notes:

• The coordinators (or me in case a group has no coordinator) will send a message to their group to start the work. A summary of what we want to achieve from the “content” part by the next meeting is:
1. thematic area groups formed and organized;
2. a comprehensive list of the entries that will be curated by each group;
3. and a definition of the format of those entries.

Week 002: 31/08/2022 to 07/09/2022

This week we welcome to the team:

• Griet Neukermans from UGent (BE).
• Ian Carroll from NASA (US);

• Thank you for joining the meeting last week. Daniela took several notes and will soon upload the minute to the meeting folder (which you can amend if necessary). Here I will just point out major conclusions of meeting:
1. The organization of the nomenclature group was established to be a general coordination occupied by Alexandre Castagna and Daniela Gurlin, thematic groups coordinations and collective of volunteers:
gaw_nfg_organogram;
2. The number a subject of the thematic groups (and their scope) will be defined by the members. Each group will self-organize (e.g., choose its coordinator). A document was created to contain the group areas, members, coordinators and scopes: thematic_areas_membership
3. Each group will produce about 2 examples of entries and those will serve as basis for a discussion to define the template / style / structure of the entries. We have created a poll to set the next meeting date. It will be send in a separate e-mail.
4. The broad strokes of the deliverable were defined and compiled in the following document: deliverables_key_points

Week 000: Foundation during the ESA Living Planet Symposium 2022

The Nomenclature Focus Group was born out of a group discussion on terminology in hydrologic optics and aquatic remote sensing during the ESA Living Planet Symposium 2022. The members of the discussion were interested in forming an initiative to solve some of the identified issues and GEO AquaWatch offered to host this effort. Initial members:

• Alexandre Castagna from UGent (BE);
• Arnold Dekker from Satdek (AU);
• Dalin Jiang from UStirling (UK);
• Daniela Gurlin (DE);
• Evangelos Spyrakos UStirling (UK);
• Igor Ogashawara from IGB (DE);
• Jens Nejstgaard from IGB (DE);
• Marit Oostende from Helmholtz-Zentrum Hereon (DE);
• Merrie Beth Neely from USF (US);
• Mortimer Werther from UStirling (UK);
• Shun Bi from Helmholtz-Zentrum Hereon (DE).
