Assessment of socio-economic issues of fishing community is an important aspect in framing a strategy for the preservation of eco-systems which leads to sustainable lagoon management. The present investigation analyses the current potential socio-economic status of the fishing community of Pulicat lagoon, the second largest lagoon in India. The socio-economic indicators considered in the study ...

Introduction: We investigated the magnitude and duration of desalination of Pulicat—a coastal lagoon ecosystem connected to the Bay of Bengal on the South-eastern coast of India—during the 2015 South India flood event which was a period of high-magnitude precipitation and riverine flooding. Methods: We estimated freshwater runoff into the lagoon using flow accumulation models for a period of 55...

In recent years, modeling has emerged as an invaluable tool for understanding the functioning of coastal lagoons. Modelling the environmental characteristics of the coastal area near the Bay of Bengal, India has received increasing attention from researchers in the past years. This interest has stimulated a scientific investigation of lagoon ecosystems, which have been studied from the physical...

Pulicat Lake is one of the major wetlands in India. It is the second largest brackish water lagoon in India next to Chilika Lake in Orissa state. Pulicat Lake sits beside the Bay of Bengal so, the study on the mouth is vital. The investigations were carried out by using multi-temporal satellite imageries of IRS P6, LISS III data for four years viz., 2009, 2011, 2012 and 2013. Subsequent changes...

coastal lagoons are complex ecosystems exhibiting a high degree of non-linearity in the distribution and exchange of nutrients dissolved in the water column due to their spatio-temporal characteristics. this factor has a direct influence on the concentrations of chlorophyll-a, an indicator of the primary productivity in the water bodies as lakes and lagoons. moreover the seasonal variability in...

Heavy metals are one of the most serious pollutants in the environment due to their toxicity, persistence and ability to concentrate along the food chain. Water bodies contaminated by heavy metals may lead to bioaccumulation in the food chain of an estuarine environment. Contamination of natural waters by heavy metals negatively affects aquatic biota and poses considerable environmental risks a...
