Abstract

Ecosystem Dynamics of the North Indian Ocean

Marine ecosystems comprise diverse organisms that have varied relationships leading to an ecosystem functioning. Every plant or animal species depends on another plant or animal species for their survival. There exists a mutual relationship between them. The interdependency could be explored in predator-prey relation or food chain. The dynamics of the ecosystem is mainly regulated by the food web. Zooplankton, Phytoplanktons, and fishes form the basis of the marine food web. These biological components respond to changes in physical oceanographic processes such as upwelling, downwelling, and radiation of planetary and trapped waves.

My research interest is to understand how these organisms are distributed and are inter-related in the ocean and what is the role of the physical process in their distribution in the Indian Ocean. The biological activities are strongly influenced by the physics of the ocean. Most often the studies made use of satellite based and ship based in-situ observation. However there are certain limitations within these studies. The advent of bio-argo floats in turn provides the vertical distribution of various parameters and helps to overcome these limitations. Also, the physical variables derived from an Ocean General Circulation Model (OGCM), when coupled with an ecosystem module can be used to simulate the response of lower trophic levels (phytoplankton and zooplankton). The ecosystem models have simplified representations of biological organisms and chemical processes. I will be making use of available observation data and the ecosystem model for better understanding bio-physical processes and provide scientific explanation to various problems.
