Title: The Online Cyanobacteria Warning and Information Service from Satellite Remote Sensing  

Date: 4 April 2019, 14:00 UTC  

This webinar was presented by Dr. Mark Matthews, founder and Director of CyanoLakes(Pty) Ltd, a commercial earth observation service provider.  Dr. Matthews specialised in bio-optical remote sensing of cyanobacteria blooms and their detection from space. He graduated from the University of Cape Town in 2014 with a thesis entitled “distinguishing cyanobacteria from algae using bio-optical remote sensing”. He has published several papers in internationally recognised journals in the field, and is the author of the chapter on bio-optical modelling of chlorophyll-a in the textbook “Bio-optical modelling and remote sensing of inland waters”. Since graduating he has led several projects funded by the Water Research Commission in South Africa and the European Commission’s Horizon 2020 programme. He founded CyanoLakes (Pty) Ltd in 2015 after winning the Copernicus Masters Ideas Challenge for best business idea for earth observation data. As the director of CyanoLakes (Pty) Ltd he is passionate about bringing the benefits of earth observation innovations to governmental water and health authorities, utilities and industry around the world through CyanoLakes’s online public health information service offering.

Abstract: At CyanoLakes we help water utilities and government agencies monitor toxin producing cyanobacteria blooms in their source waters, helping them use their limited resources more effectively and become more informed and responsive. During this talk we will discover how water utilities and government authorities can use CyanoLakes paid services to enhance and supplement their ongoing monitoring programs.

Title: Why a new generation of EO sensors for water quality needs a new generation of in situ validation instruments?
Date: 31 January 2019, 14:00 UTC
This webinar will be presented by Dr. Marnix Laanen, co-founder and co-owner of Water Insight, an SME dedicated to water quality remote sensing using both image data and close sensing in situ spectrometers based in Wageningen, The Netherlands. He has a PhD. in Earth and Life Sciences from the Vrije Universteit of Amsterdam specialising in the retrieval of Coloured Dissolved Organic Matter from close sensing spectra validated by laboratory in situ sampling. Within Water Insight Marnix is involved in various H2020 projects and in the optical instrument development (both WISP-3 and WISPstation).
Abstract:  With the launch of the Sentinel 2 and 3 satellites a new generation of EO sensors is commissioned. However, the use of the current in situ validation instruments for these new sensors might not suffice for a number of reasons, especially for water quality retrieval. The atmospheric correction methods for S2 and S3 over surface water are still in development and is troublesome for S2 (as having a band setting primarily for land applications). In this webinar we will explore the requirements for a new generation of in situ optical instruments for S2 and S3 sensor validation.

GEMS/Water: Evolving a Global Long-term Water Quality Data Repository
27 September 2018
This webinar, coauthored by Philipp Saile (Hydrologist, Coordinator), was presented by Dmytro Lisniak (Hydrologist, Data Analyst) of the GEMS/Water Data Centre, operated by the International Centre for Water Resources and Global Change (ICWRGC), German Federal Institute of Hydrology.
 Abstract: The Global Environment Monitoring System for freshwater (GEMS/WATER) was the first programme of its kind to address global issues of water quality through a network of monitoring stations in rivers, lakes, reservoirs and groundwater on a global scale. Technical cooperation with developing countries was the main focus of GEMS/WATER during its first phase. The program has contributed to the establishment and expansion of national water quality monitoring systems in many countries. Current engagements focus on increasing the availability and promoting the shared access to quality assured data that serves as a base for evidence informed decision making, the facilitation of quality assessments to inform policy makers and the support of work on indicators for the Sustainable Development Goals. In order to provide the information and knowledge base for the development and implementation of policies and sustainable management of freshwater ecosystems worldwide, the GEMS/WATER programme is evolving into an open, collaborative water quality data, information and knowledge hub.

Special Horizon2020 Monocle/GEO AquaWatch co-hosted webinar!

Sustainability of Future Environmental Observation Networks

24 October 2018 

For this seminar, invited speakers/panellists were MONOCLE Expert Advisory Board members Debbie Chapman (University College Cork and UN Environment GEMS/Water), Henrik Steen Andersen (European Environment Agency) and Steve Greb (GEO AquaWatch,University of Wisconsin-Madison) and MONOCLE contributors, Kathrin Poser (Water Insight,WP5 lead) and Oliver Clements (PML).

Abstract: The third MONOCLE webinar in the series addresses sustainability of environmental monitoring networks, in particular hybrid services of in situ and satellite observation networks. How do we safeguard long-term measurement series while sensor technology continues to improve? How should data collection be funded to be sustainable? How should a multi-scale observation network feed into regional and global reporting strategies?

An overview on current water quality monitoring policy and challenges will be presented, including discussion of how MONOCLE research may contribute to reaching the European and global monitoring goals.

CyanoAlert – Space based cyanobacteria information & services
 27 November 2018
 This webinar will be presented by Petra Philipson, PhD in aquatic remote
 sensing and remote sensing consultant since 2003. Co-founder, vice manager
 and consultant at Brockmann Geomatics since 2011, with personal interest and
 focus on aquatic national, European and global assignments and research and
 development projects.
 Abstract: CyanoAlert is a three-year project funded by the European Commission ending in spring 2020 ( The project aims to provide customers in government, commercial and environmental sectors with up-to-date, accurate and relevant information on the health risks posed by cyanobacteria blooms in water bodies through utilising Copernicus Satellite Earth Observation data. The service will offer weekly updates, forecasts, and near real-time information on cyanobacteria blooms and eutrophication (chlorophyll-a) through its service portal and mobile application. The webinar is a presentation of on-going project activities and results achieved so far.
