An assessment of various threats to the olive ridley turtles at Rushikulya rookery of Orissa in India was investigated during 2003-04 and 2004-05 seasons. Data on adult mortality, predation of eggs and juveniles, beach erosion and Casuarina plantation along the beach were collected. Turtle mortality was low at Rushikulya compared to rest of the Orissa coast.

Shipboard iron- and macronutrient-addition experiment was conducted in the Central Indian Ocean, to investigate the variations of carbon in different forms and its records for plankton activities. Experiments were conducted in four 500-L acrylic barrels with the surface seawater near 24

The breadth and complexity of the global ocean, covering more than 70 percent of Earth's surface, have challenged our ability to explore, comprehend, predict and even control its processes and behavior. It is now generally accepted that the world oceans are by far the largest sink of anthropogenic CO2 one the dominant cause of global warming on our planet.

Multivariate statistical techniques, such as Cluster Analysis (CA), Discriminant Analysis (DA), and Principal component analysis (PCA) were applied to evaluate the temporal/spatial variations in marine water quality of Mumbai and to identify pollution sources. Hierarchical CA grouped 12 sampling sites into three clusters of similar water quality characteristics.

The present study consist the absorption, accumulation and partitioning of eight metals in order to find out the phytoremediation potential of the mangrove species Rhizophora mucronata (Lam.) in Alibag, Maharashtra, India.

Chilika lagoon, along the east coast of India, is the largest brackish water lagoon in Asia. Hydrodynamics of an aquatic system like Chilika is extremely important. It has significant impact on sediment and pollutant transport, distribution of nutrients in water and sediments, and the productivity of the system.

Present study consist the spatial and temporal variations of depth, temperature and salinity, currents, flushing times and classification of the Krishna estuary. Temperature exhibited a distinct seasonal variation with higher values in premonsoon (30.0

Zn, Cu and Pb levels in the aquatic phase and underlying surface sediment from three stations (viz. Shankarpur, Canning and Bali Islands) of the coastal zone of West Bengal during different seasons in 2002 were recorded. The order of the heavy metal level in the ambient media of the selected stations is Zn> Cu> Pb.

Six major groups of enteric bacteria, viz, Faecal coliforms, E. coli, Shigella spp., Salmonella spp., Vibrio parahaemolyticus and Vibrio cholerae were screened for the present study. The overall percentage occurrence of enteric bacteria in water and sediment was maximum accounted for Vibrio parahaemolyticus (81.7%) and minimum for Salmonella spp.

Chattonella marina, a marine raphidophyte algae which produces haemolytic compounds is capable of damaging fish gills. Blooms of this algae were observed along North Kerala during September 2002, reaching maximum cell density 28
