The National Centre for Sustainable Coastal Management (NCSCM), headquartered in Chennai, is an autonomous institution under the Ministry of Environment, Forest and Climate Change (MoEFCC). It was established to support India's coastal management objectives under the Coastal Regulation Zone (CRZ) Notification 2019. A Research Associate conducts scientific studies on coastal ecosystems (mangroves, seagrass, coral reefs), monitors shoreline changes using satellite data, prepares Coastal Zone Management Plans (CZMPs), and supports states in implementing CRZ regulations. They also contribute to the Environment Protection Act 1986 implementation in coastal zones.

The Coastal Regulation Zone (CRZ) Notification 2019 issued under the Environment Protection Act 1986 regulates activities along India's coastline (approximately 7,500 km) and in tidal waters up to the influence zone. It classifies coastal zones into CRZ-I (ecologically sensitive — mangroves, coral reefs, no-development zone), CRZ-II (urban built-up), CRZ-III (rural/undisturbed), and CRZ-IV (Andaman & Nicobar, Lakshadweep). NCSCM plays a key role in preparing the Hazard Line maps and Coastal Zone Management Plans that determine CRZ boundaries. EIA Notification 2006 also mandates EIA for coastal projects above a certain scale.

Marine ecology questions cover mangrove ecosystem structure and functions (carbon sequestration, shoreline protection, fish nursery habitat), coral reef health assessment (bleaching, acidification, ENSO impacts), seagrass distribution and dugong habitats, intertidal ecology (rocky shores, sandy beaches, mudflats), estuarine biogeochemistry, coastal erosion and accretion processes, sea level rise projections for India's coasts (IPCC AR6 projections), and the biology of commercially important marine species. Familiarity with India's declared Marine Protected Areas and Ramsar coastal wetland sites is expected.

NCSCM provides expert technical review for EIAs of coastal infrastructure projects including ports, harbours, thermal power plants, SEZs, and tourism resorts that require environmental clearance under the EIA Notification 2006. For Category A coastal projects, NCSCM scientists may serve on the Expert Appraisal Committee (EAC) under MoEFCC. NCSCM's Hazard Line maps and CZMPs are mandatory references in coastal project EIAs. The Environment Protection Act 1986 provides the legislative basis for NCSCM's advisory function in environmental clearances involving coastal and marine ecosystems.

The research aptitude section covers scientific methodology, hypothesis testing, statistical analysis (ANOVA, correlation, regression for environmental data), GIS and remote sensing for coastal mapping (shoreline change analysis, mangrove extent mapping), oceanographic data analysis tools, report writing, and literature review methods. Familiarity with oceanographic instruments (CTD casts, tide gauges, ADCP), satellite-derived ocean color products for phytoplankton monitoring, and marine biodiversity assessment protocols (coral reef health monitoring, mangrove enumeration) is beneficial.
