This Group addresses scientific issues related to near surface dynamic processes. The focus has been understanding the cause and effect of slope failures. With the help of satellite imagery, field studies and geochemical characterization of soil/rock the group attempts to help predict landslides and suggest mitigation. The activities of the group also include understanding of hydrocarbon fluid movements in the crust leading to mineralization.

The focus of the Marine Science Group has been the understanding of waves, currents and sediment transport and their effects on beaches and nearshore including modelling of coastal processes of the west coast of India. The activities include setting up of high-resolution numerical models capable of simulating coastal ocean dynamics and boundary exchanges, establishing video based Coastal Monitoring network and investigating on evolution of Alleppey Terrace and its impact on shelf economic mineral deposits.

The national network project on Submarine Groundwater Discharge, to quantify the amount of fresh groundwater discharge to Bay of Bengal as well as to Arabian Sea through coastal aquifers, also forms a major activity under this subtheme of NCESS. The program on SGD is implemented by NCESS with the participation of twelve agencies in the country using different methods of remote sensing, hydrogeological, hydrochemical, isotopic and modelling techniques.

The Atmospheric Science Group in NCESS is actively engaged in the basic research on atmospheric clouds, thunderstorms, lightning and atmospheric electricity, and regional climate over Western Ghats to improve the forecasting of atmospheric natural hazards. It is a fact that the value of weather, climate, and environmental data, and forecasts is growing in the country as it linked to economy. Weather affects aviation, air quality, health, ground and marine transportation, defense, agriculture, fisheries, water, energy, construction, tourism, and many other sectors of the economy.
