August 2010 Article: Tracking Cholera in Coastal Regions Using Satellite Observations, by Antarpreet S. Jutla, Ali S. Akanda, and Shafiqul Islam.
Chlorophyll in the Bay of Bengal
Our Featured Series on Satellite Hydrology concludes with an article in which Antarpreet S. Jutla et al. investigate relationships between cholera incidence and coastal processes and explore the utility of using remote sensing data to track coastal plankton blooms, using chlorophyll as a surrogate variable for plankton abundance, and subsequent cholera outbreaks.
Though satellites are not necessarily a good substitute traditional hydrologic data, they can be invaluable where politics or logistics prevent collecting or sharing on-the-ground observations. Moreover, the large areas observable can provide an important complement to sparse terrestrial or oceanic observations.
