Reef and wild fishery conservation through exploiting satellite remote sensing of the marine carbonate system
We will first demonstrate that observations from space can be used to estimate surface total alkalinity and total dissolved inorganic carbon with performance comparable to that of in situ driven empirical approaches. For alkalinty, the global combined uncertainties for these observations are ±17 μmol kg-1 . We will then present early results from the European Space Agency Satellite Oceanographic Datasets for Acidification (OceanSODA) project demonstrating how large spatial-scale upwelling (of low pH waters), river outflows and compound events, and their subsequent impact on the surface water carbonate system, can be observed from space. Collectively this work exploits the synergistic use of remote sensing observations, in situ based climatologies, in situ and model re-analysis datasets, empirical statistical analyses and machine learning approaches.
These advancements are intended for supporting coral reef conservation, the designation of marine protected areas and investigating the health of wild fisheries, and early results of these applications will also be presented. These routes for exploitation are being co-developed with the U.S. National Oceanic and Atmospheric Administration (NOAA) and the World Wide Fund for nature (WWF).
