© 2012, Springer-Verlag Berlin Heidelberg. Marine habitats are comprised of zones termed coastal terrestrial, open water, and the ocean bottomuntil several meters deep. Several physical parameters, e.g., temperature, salinity, tides, currents, winds, etc., play a major role in defining the marine habitat. Malthus and Mumby have listed marine ecosystem to comprise mangroves, seagrasses, coral reefs, lagoonal microbial mats, shoreline features, sub-littoral zone benthos and overlaying water column features. The reflectance of these features can be measured by remote sensing methods to provide synoptic data at various scales. Such data are essential requirements for coastal managers to be able to address issues facing these diverse habitats. In most countries, these environments are either being degraded or not inventoried. This is due partly to inaccessibility and partly due to large spatial coverage, leading to high costs when applying conventional methods.
