A series of satellite images composited by a UAH graduate student so they track the growth and disappearance of an algal bloom in a Guatemalan lake was chosen for publication by the company that created the software she used for the project. Africa Flores, who will soon graduate with a masters of science degree in Earth system science, developed an algorithm that uses hyperspectral data from NASA's EO-1 satellite to measure and track changes in aquatic chlorophyll as a proxy for water quality in Lake Atitlan in Guatemala. This method can be transferred to study other lakes and large rivers in the region, where water quality information is otherwise scarce.
