AquaWatch-Measuring Water Quality from Space

"Introducing AquaWatch - the Group on Earth Observations (GEO) Water Quality Initiative"

Good water quality is essential for the human, ecosystem and economic health. Its management implications span many areas of Sustainable Development - degradation of water quality can result in human exposure to disease and harmful chemicals, reduction in productivity and diversity of ecosystems and damage to aquaculture, agriculture and other water-related industries. The use of satellite remote sensing offers a cost-effective, spatially and temporally comprehensive tool for observing often highly dynamic water quality phenomena in coastal and inland waters and is particularly beneficial for monitoring previously unsampled locations and areas with limited access. New and improved sensor technologies, novel algorithm development, and considerable improvements in data availability and image processing capabilities have resulted in major advancements in remote sensing of coastal and inland waters, and a demonstrable increase in the confidence in derived water quality products.

The Group on Earth Observations (GEO) AquaWatch is the water quality community of practice focused on the synthesis of remotely sensed and in situ data for improved global data products that are open access. The overall goal of the AquaWatch Initiative is to develop and build the global capacity and utility of Earth Observation-derived water quality data, products, and information to support effective monitoring, management, and decision making.

This Bite will discuss the science behind satellite-derived water quality measurements, the activities of GEO AquaWatch and proposes areas of collaboration with the World Bank. See disruptive tech in action!

About the Presenters

Steve Greb

Director of the Group on Earth Observation (GEO) AquaWatch Initiative

Steve is currently an associate fellow at the University of Wisconsin-Madison Aquatic Sciences Center and holds a research scientist position within the Cooperative Institute for Meteorological Satellite Studies at the Space Science and Engineering Center at UW. Steve recently left the Wisconsin Department of Natural Resources where he worked as an aquatic research scientist for the past 32 years addressing new and emerging environmental issues in the State. His work topics included acid rain impacts on aquatic ecosystems, thermal pollution in the urban environment, effects of forestry best management practices on stream water quality, nearshore nutrient dynamics; and hydrologic impacts on changing climate conditions. Over much of the last 20 years, he has focused on the use of remote sensing to measure water quality from space.
