Monitoring Aquatic Vegetation with Remote Sensing

Aquatic vegetation (AV) provides a habitat for numerous small invertebrate and fish species. Kelp forests, for example, are the dominant coastal ecosystem in temperate waters. The presence of AV in coastal waters is a normal occurrence, as it is an important component of the natural marine environment. Nevertheless, in the last decades, the appearance of increasingly abundant mats of certain floating species in other coastlines (i.e., Caribbean/Atlantic) has become a nuisance to local economies.

Sargassum mats, for example, are reaching coastal areas by tons every year and there is still not a clear hypothesis as to why this is happening. While these mats provide an important habitat for small invertebrate and fish species, they also affect the amount of light reaching shallow-water ecosystems like coral reefs and seagrass beds. Several NASA-funded efforts are currently using remote sensing techniques to monitor the presence of Sargassum in Caribbean and Atlantic waters, while others have a citizen science-oriented approach to follow giant kelp populations in the Pacific.

This training will combine basic information on the remote sensing of AVs, spectrometry of aquatic/coastal vegetation, and a demonstration of the NASA-funded Floating Forests citizen science tool.
