Chemical Diagenesis of Wetland Sediments

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.
