Mangroves are highly productive, dynamic and they serve as a vital
source for organic matter in the sediments. The study area,
Atirampatinam mangrove, is located along the South East of India. To
understand the temporal and spatial changes in the mangroves forest,
coastal wetland and shoreline changes were studied from toposheets and
satellite data using image processing and GIS techniques. Four cores
samples representing different mangrove environments were collected and
analyzed. Rainfall data collected for 100 years had been analysed to
identify the solar cycle.
