Bioconcentration of trace metals by Saccostrea cucullata (von Born 1778) from Andaman waters
(CSIR-NISCAIR, 2013)Assessment of trace metals (Zn, Cu, Fe, Pb and Ni) in water, sediment and an oyster, Saccostrea cucullata, was carried out in five stations around Port Blair. Concentration of these metals in water, sediment and the oyster ... -
Cochin backwaters: A sad story of manipulation
(The Royal Swedish Academy of Sciences, 1997)Cochin backwaters, along the south west coast of India have been altered several times for various causes and the system has undergone tremendous environmental changes as a consequence developmental activities and associated ... -
Ecobiological assessment of a freshwater lake at Schirmacher Oasis, East Antarctica, with reference to human activities
(Current Science Association, 1998)The scale and magnitude of probable impact of human activities over a decade (1983-1994) on the freshwater lake Priyadarshini, at Schirmacher Oasis, East Antarctica, was assessed through an ecological study conducted over ... -
Effects of natural and human-induced hypoxia on coastal benthos
(European Geosciences Union, 2009)Coastal hypoxia (defined here as <1.42 ml L sup(-1); 62.5 mew M; 2 mg L sup(-1), approx. 30% oxygen saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result of natural upwelling or from ... -
Foraminiferal fauna from the Cochin backwaters: Biological indicators of man-made changes in the environment
(K.R. Publishers, Udaipur, 1996)Sixty foraminiferal species belonging to 38 genera and 23 families have been recorded from grab sediments of the Cochin backwaters. Of all the species Ammonia baccarii is the most dominant and successful form in the throes ... -
Human influences, ecological transitions and uncertainties of extrapolation of risks of selected sea level rise scenarios to India's coastal megacity, Cochin
(IHP-OHP-UNESCO; Bremerhavan; Germany, 2002)Despite the magnitude and urgency of the issue, scientific understanding of climate change and potential risks to Indian coastal cities have not been fulfilled till recently; though it has long been recognized world wide ... -
Indian estuaries: Dynamics, ecosystems, and threats
(National Academy of Sciences, 2011)Indian estuaries have special features that are derived from occurrence of the wet Indian Summer Monsoon (June-September) and hence have been called monsoonal estuaries. High runoff during the wet season and a 8-month long ... -
Marine pollution - What are we heading for?
(Indian National Science Academy, New Delhi (India), 1999)Unlike the open ocean, the coastal zone is the most affected and vulnerable to human abuse with several nearshore areas including well-flushed regions and enclosed and semi-enclosed seas getting increasingly polluted. This ... -
Monitoring the impact of simulated deep-sea mining in Central Indian Basin
(Taylor and Francis, 2005)Monitoring of deep-sea disturbances, natural or man-made, has gained significance due to the associated sediment transport and for the ensuing alterations in environmental conditions. During the Indian Deep-sea Environment ... -
Our threatened archaeological heritage: A case study from the Tamil Nadu Coast
(Current Science Association, Bangalore, 1997)From the beginning of the Christian era, a number of sites having contact with the Roman world were in existence on the coastal belt of India. There are several indirect references in the literature which suggest that the ... -
Restoration on degraded sand dunes on flattened beaches of Goa: Implication for coastal management.
(Resources and Management, 2010)This paper describes how an environment friendly technique can curtail loss of beach sand due to wind, and proposes how damaged sand dunes can be regenerated. -
The nitrogen cycle in the Arabian Sea
(Elsevier, 2005)Despite their importance for the global oceanic nitrogen (N) cycle, estimates of N fluxes in the Arabian Sea remain in considerable uncertainty. In this report, we summarize current knowledge of important processes, including ...
