The explosions and radiation leaks in Fukushima nuclear power plants, a result of earthquake and resultant tsunami waves, have impelled nations to review safety situation in their nuclear facilities. The disaster in Japan has reinforced the reality that experts can neither predict the magnitude of a disaster nor can they take adequate measures in unforeseen circumstances.

Ecological diversity in Sunderban is at the threshold of decline. The fragile land here is being swallowed every day by gradual sea level rise, coastal erosion and tropical cyclones. Besides the global cause of sea level rise i.e. thermal expansion of sea water also responsible is the land degrading anthropogenic activity. An unsustainable situation has crept in the deltaic plain when natural capital is being used up faster than it can be replenished.

Beaches along most of the shorelines of the world, exhibit variations in their geometric form over different time scales in response to the prevailing dynamic forces due to waves, tides and associated currents. The periods and intensity of erosion and accretion alternate over time and are generally coupled to nearshore wave conditions. The nearshore parameters, viz. wave runup, wave setup and wave energy, have been evaluated during storm and normal conditions of SW monsoon (June-September) and NE monsoon (November-February) by empirical parameterization along the Visakhapatnam coast.

There have always been attempts to replace inorganic fertilizers with organic fertilizers from natural sources for enhancing the growth of commercially important plants. In continuation to the same efforts, an attempt was made to demonstrate the growth enhancing properties in the extracts of two species of seaweeds (Padina tetrastomatica and Sargassum sp.) used on black mustard plant (Brassica nigra L.).

A general survey of the fertility of 25 estuaries, based on their concentrations of nutrients, phytoplankton and zooplankton assemblage and fish production in each, as far as these are known, has been enumerated. In all 25 estuaries, of both the coasts 8 from the east coast which end up in the Bay of Bengal and the rest which the Arabian Sea have been covered.

Mangrove forests in India are unique to have spectacular coverage both in wet and arid coasts of the country with a record of 4011 biological species including the globally threatened species. In spite of growing threats, the mangrove area has been well protected in the last two decades due to strong policy, legal framework and governance.

The above ground biomass (AGB) and carbon stock of Excoecaria agallocha were estimated in western and central Indian Sundarbans for five successive years (2005-2010). The two sectors are drastically different with respect to salinity on account of massive siltation that prevents the flow of fresh water of the River Ganga to the central sector of Indian Sundarbans.

The paper deals with the Integrated Coastal Zone Management (ICZM) of the Midnapore Coast, West Bengal. It is suggested that management studies should include baseline information related to rainfall, runoff, tidal rhythm, currents and waves with their related aspects.

Diurnal variation in trawl catches and its influence on energy efficiency of trawler operations are discussed in this paper, based on data on landings of a Japanese factory trawler which operated in the Indian waters during 1992-93.

The knowledge of traditional medicines from marine resources shows that very little information has been preserved or recorded so far. We do not know how much information still exists.
