Speaker: Dr. Kelly Luis - NASA Jet Propulsion Laboratory, California Institute of Technology. In light of recent launches of hyperspectral remote sensing missions, such as PACE, PRISMA, ENMAP, EMIT, and upcoming ones like GLIMR, we will have an abundance of new observations for understanding our changing aquatic ecosystems. Prior to the inundation of data, we have a unique opportunity to revisit how past and present ocean color remote sensing missions have been used to investigate aquatic ecosystems processes; and to distill important lessons for best leveraging future hyperspectral aquatic observations. This talk will center remote sensing of algal blooms, including observations from airborne and spaceborne sensors such as PRISM, MODIS-Aqua, and EMIT. I will highlight how current ocean color missions can be combined with Sentinel 5P-TROPOMI, a sensor able to detect fluorescence information in variable atmospheric conditions, to increase spatial and temporal harmful algal bloom (HAB) information. To refine our understanding of the dominant phytoplankton communities contributing to algal blooms, I will demonstrate how airborne hyperspectral imagery from PRISM can be used to test data science approaches for characterizing phytoplankton community composition. Lastly, I will present how hyperspectral information from EMIT on the International Space Station can reveal finer spatial information insight on inland HAB dynamics.
