The paper was published in Nature and entitled “Widespread deoxygenation of temperate lakes” (see full citation below). Study co-author Kevin C. Rose, is a professor of biology at Rensselaer Polytechnic Institute, and an active member of GEO AquaWatch Working Group 3.
Rose and his co-authors found dissolved oxygen levels declined in 393 temperate lakes in the United States and Europe between 1941 and 2017 – a result of anthropogenic climate change altering the physical and chemical environment in lakes. Oxygen values dropped in both surface and deep lake waters, but for different reasons. Surface values mostly dropped due to less soluble oxygen in warmer surface waters, but enhanced phytoplankton production led to more surface dissolved oxygen in some of the most productive warming lakes. Dissolved oxygen declined in deeper waters was associated with thermal stratification and reduced water clarity limiting primary production and enhancing respiration, but not altering gas solubility in the warming lakes. Lake oxygen declines were ~3-9 times greater than oxygen declines observed in oceanic waters, threatening ecosystem services, and leading to increased fish kills, algal blooms and methane emissions.

On June 8th, World Oceans Day, UNESCO’s Intergovernmental Oceanographic Commission announced the first Actions officially endorsed as part of the United Nations Decade of Ocean Science for Sustainable Development, 2021-2030 (the ‘Ocean Decade’). The Committee on Earth Observation Satellites Coastal Observations, Applications, Services, and Tools (CEOS COAST) was selected as a Contribution to the Ocean Decade, and GEO AquaWatch is proud to be among the Leadership Team of COAST’s Land2Sea Pilot. Paul DiGiacomo, NOAA (GEOAquaWatch Co-Lead and patron) is the Co-Lead of CEOS COAST along with Raj Kumar, ISRO.

The NASA Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Mission is assessing the terrestrial-land user community to characterize its composition, remote sensing needs, data product applications, and research interests.
If you are a professional in the terrestrial-land field, you have been identified as someone with insight into how PACE data products can be used and applied and NASA is interested in how you might use PACE satellite data in your work. Your answers will help NASA anticipate the scope of PACE science and applications as well as the socioeconomic impact of future PACE products.
NASA invites you to take this brief survey. Participation is entirely voluntary, and your answers will be anonymous. Please click on the following link to proceed: https://www.surveymonkey.com/r/PACE_terrestrial
If you would like further information about this questionnaire, please contact PACE Applications by email at email@example.com.
Thank you for your time and attention in helping NASA improve how we engage with the mission user community!
PrimeWater has launched a #survey to understand the attitudes and preferences of different #stakeholders in using #EarthObservation (EO) services.
*We would like to know what you think!*
Your feedback is very valuable to us as it will contribute to our understanding of how social and institutional attributes determine the adoption of EO-based services in #decisionmaking processes.
The survey will take 15 minutes to complete. Your participation in the research is completely voluntary.

This position will work out of Honolulu, HI – this is not a remote position.
The Joint Institute for Marine and Atmospheric Research (JIMAR) is currently recruiting for a permanent Researcher position to work with NOAA’s CoastWatch/OceanWatch/PolarWatch Program (https://coastwatch.noaa.gov/cw/index.html) who will be based at the Pacific Islands Fisheries Science Center’s Ecosystem Sciences Division in Honolulu, HI. The Researcher will manage the OceanWatch satellite remote sensing datasets and data platforms (website, THREDDS, ERDDAP) and will also have the opportunity to conduct original research for the creation of new and value-added oceanographic and climate products derived from satellite remotely sensed data and from atmosphere-ocean general circulation models. Developing, managing, and conducting OceanWatch outreach and education activities is also an important aspect of the position.
Primary qualifications include a PhD from an accredited college or university in Oceanography, Marine Biology, Climate Science, or Mathematics and professional experience working with satellite remotely sensed oceanographic data or climate products to quantitatively derive information about biological physical or oceanographic phenomena. A Master’s degree from an accredited college or university and at least five (5) years of relevant work experience in the above fields may substitute for a PhD.
DEADLINE: Please note the deadline to apply is 05/28/2021
Dr. Brittany Huntington is the hiring manager. More information about applying to this position can be found by navigating to www.rcuh.com and clicking on “Job Postings” and Project Name “JIMAR” (ID# 221226). Please note applicants must be US citizens or permanent residents.
