Coastal zones are dynamic interfaces of land and water of high ecological diversity and critical economic importance. The boundaries, shape and size of this coast change constantly under the influence of both natural and anthropogenic factors. The study area, Tupilipalem is one of the proposal sites for constructing a major port, to be named Dugarajapatnam Port, along the east coast of Andhra Pradesh, India. We have used multitemporal satellite images of IRS P6 LISS-III and Landsat 8 OLI/TIRS data from 2011 to 2015 to delineate changes in Tupilipalem coast. The subsequent short-term lagoon mouth closure and the long-term coastal erosion and accretion rates have been calculated for the periods between 2011 and 2015. Low river inflow, wind, tides, the movement of the waves and littoral currents play a key role in the closure of the lagoon mouth and also for the dynamic activities of erosion and accretion. Moreover, the impact on socio-economy and ecology of the study area during the lagoon mouth closure period has been studied.

Estuarine sediments in the<63 μm size fraction were collected from 15 stations within the Tambaraparni River Estuary, located on the east coast of India. The distribution of the heavy metals Cd, Co, Cr, Cu, Ni, Pb and Zn was recorded. Our analysis distinguished two groups of elements. First, Cd, Pb and Zn, which occurred in higher than expected concentrations indicative of pollution, and second, Co, Cr, Cu and Ni, which occurred at background levels. The highest metal concentration found in the study area was for Zn (1200 μ g·g−1), and the lowest was for Cd (0.42 μ g·g−1). It is presumed that river run-off, industrial waters and untreated domestic waters are major contributors to heavy metal pollution in the Tambaraparni River Estuary. The concentrations of heavy metal species in surface sediments (<2 m water depth) of the Tambaraparni Estuary were studied to determine the extent of anthropogenic inputs from catchment areas and to understand anthropogenic effects on geochemical process in this tropical estuarine system.

This work investigates the metal pollution documented in the skeletons of selected coral species like Acropora formosa, Montipora digitata and Porites andrewsi from the Tuticorin Coast, one of the least studied areas in the Bay of Bengal. Relating heavy metal concentrations to morphological features of skeletons, highest concentrations of all the metals (except Cu and Zn) were found in ramose or branching types of corals. Irrespective of their growth characteristics or patterns, all these species displayed higher concentrations of Pb, Ni, Mn, and Cd within the skeletal part. The study area is currently exposed to a larger degree of metal pollution (natural and anthropogenic) than even before, as a result of the increasing environmental contamination from sewage discharges, the misuse of agricultural chemicals and fertilizers, and top soil erosion. The concentrations of heavy metals obtained in the present study are compared with values from earlier works around the world. This study indicates that corals are vulnerable to the accumulation of high concentrations of heavy metals in their skeletons and therefore can serve as proxies to monitor environmental pollution.
