Satellite based retrieval of geo-physical parameters for coastal processes assessment

Coastal processes are more complex due to the interaction of bathymetry, wave, tides and land-sea breeze etc., Satellite sensors such as Altimeter, Scatterometer, Radiometer and SAR etc., provides information regarding geo-physical variables. Algorithms developed using radiative transfer models and statistical methods are needed to retrieve geo-physical parameters from these satellite measurements.

Eco-system change direction and responses due to coastal change using high resolution IRS-data sets

Understanding how the coastal ecosystems are changing due to changing coast is an area of importance in India due to natural as well as anthropogenic activities in coastal areas. Remote sensing can take an important role in quantifying and monitoring these changes at local to regional scale. The new high resolution remote sensing datasets from IRS series of satellites can take an important role in studying the changes happening in coastal ecosystems in India

In-situ studies of phytoplankton cultures to understand changes in the absorption spectrum in response to different environment variables for developing methodologies for satellite retrieval

Retrieval of spectrum information of dominant phytoplankton groups from satellite ocean colour data especially for case 2 waters is complex and requires good amount of in situ studies from pure cultures to understand how this varies due to age of the culture, between different groups and also with nutrient manipulations. In recent years several methodologies have been developed to extract spectrum information from satellite ocean colour data however this requires important validation to make such techniques operational in the era of OCM.
