Role of marine bacteria viz. Marinococcus albus, Methylobacterium mesophilicum and Nocardia otitidiscaviarum in bioremediation of crude oil contaminated Alang sea coast has been evaluated in the present study. Optimum concentrations of inorganic nutrients N, P & K as urea, super phos and potash fertilizers respectively on growth and degradation has been determined.

The water quality and primary productivity of Valanthakad backwater (9

Concentration of metals (Mn, Al, Fe, Cr, Cu, Zn, Pb, Cd, Co and Ni) in eight different seagrass species of Andaman Islands were analyzed using Inductively Coupled Plasma Optical Emission Spectrometer. The concentration of Mn was maximum in almost all the seagrasses, whereas Co recorded minimum concentration.

Intensive sampling was carried out in the marine environment of Mumbai and Jawaharlal Nehru ports to investigate the composition of benthic sessile population on three different occasions during 2001 to 2002. this study recorded 29 species of hard substratum fauna and 14 associated fauna.

Comparative study of heavy metals in forty species of red seaweed belonging to twenty six genera from three different coastal areas (Buleji, Paradise Point and Nathia Gali) of Karachi, Arabian Sea was carried out over the period of three years. There is high variability in metals concentration with in, seaweed species, sampling sites and collection time.

Bacterial population in the coastal water of Orissa, up to 10 km from shoreline along 6 transects were observed during 2005-06 and 2006-07. Total viable counts (TVC), total coliforms (TC), faecal coliforms (FC), faecal streptococci (FS), presumptive E. coli, Shigella, Salmonella, Proteus/Klebsiella, total Vibrio, Vibrio cholera, V.

Manakkudy estuary, located on the South-West coast of India has production of seaweeds to an amount of 15.59 kg/m2/yr. Four different types of seaweeds viz., Chaetomorpha aerea, Enteromorpha compressa, Gracilaria verrucosa and Hypnea musciformis were observed in this estuary. Highest production of biomass (C. aerea = 842.33

Assessment of coral disease prevalence was carried out in six islands in the northern region of the Gulf of Mannar during February 2007. Assessment was made in two sites in each island and three transects were laid in each site. white band, white plaque, white spot, pink spot, black spot, black band, yellow spot, yellow band and tumors were the observed common diseases in this regime.

Water and sediment samples were takes near the sewage discharge point on the eastern Red Sea Coast of Jeddah and analyzed for PAH and fecal sterols like coprostanol, cholesterol and cholestanol. PAH were estimated

Presents study consists the results of the Sun photometer measurements of aerosol optical depth (AOD) over the northern Arabian Sea during December 4-17, 2004 along with OCEANSAT-1 Ocean Colour Monitor (OCM) data derived AOD estimates. In-situ AOD ranged between 0.15-0.38 at 500-nm wavelength (with a mean of 0.274).
