Moderate Resolution Imaging Spectroradiometer (MODIS) imagery depicting Lake Victoria normalized difference vegetation index (NDVI) extraction before (left) and after (right). The left shows an unprocessed satellite image, while the NDVI image is shown on the right, depicting aquatic vegetation in green. Bright green areas indicate dense aquatic vegetation. Source: USGS.Invasive aquatic vegetation has been a serious issue in Lake Victoria over the past decade, hindering transportation as well as a profitable fishing industry. Remote sensing was used to map the spatial extent of aquatic vegetation on the surface of Lake Victoria as well as create time series animations to show growth and movement of the vegetation. Our results will be used by SERVIR and the Lake Victoria Fisheries Organization to conduct operational satellite-based surveillance and to protect local fisheries.

Image of a satellite with Earth in the backgroundDuring the 2011 NASA DEVELOP summer term, 140 students and young professionals investigated topics ranging from tracking the public health exposure to air quality and extreme heat events in Los Angeles to the ecological impacts of the 2011 tsunami disaster in Japan. Out of 22 research projects, a panel of scientists chose one team as the overall winner, and named three runners-up, based on projects that garnered the best comments and dialogue.
