Role of iron deficiency in production and remineralization of organic matter in the Arabian Sea
(Solas, 2007)The Arabian Sea contains the only major western-boundary upwelling system in the world's oceans During summer, strong southwesterly winds bring up subsurface waters from depths of up to 200m off Somalia, Yemen and Oman ... -
Sources of organic matter and microbial community structure in the sediments of the Visakhapatnam Harbour, east coat of India
(Elsevier, 2010)Organic matter in the coastal sediments originates from various terrestrial and marine sources. Within the sampling sites, relative inputs from these sources may vary and can influence the microbial community structure. ... -
Larval development, sensory mechanisms and physiological adaptions in acorn barnacles with special reference to Balanus amphitrite
(Elsevier, 2010)Barnacles have drawn the attention of many naturalists and often dominate fouling communities. Balanus amphitrite, is a shallow water acorn barnacle capable of inhabiting expanses from supralittoral to subtidal levels, and ... -
Assessment of oxidative stress indices in a marine macro brown alga Padina tetrastromatica (Hauck) from comparable polluted coastal regions of the Arabian Sea, west coast of India
(Chinese Academy of Sciences, 2010)Oxidative stress and antioxidant defence systems were assessed in a marine brown alga Padina tetrastromatica, commonly occurring from the tropics. Lipid peroxidation (LPX) and H sub(2) O sub(2) were measured as oxidative ... -
Placer chromite along south Maharashtra, central west coast of India
(Current Science Association, 2010)We describe here the onshore occurrence of placer chromite, its mineralogy, geochemistry and reserve potential from a 12.5 km stretch (Pirwadi-Talashil) of south Maharashtra coast, India. The sediments in the area are ... -
Fluctuations in productivity and denitrification in the southeastern Arabian Sea during the Late Quaternary
(Current Science Association, 2010)Sedimentological and stable isotopic characteristics of sediments have been studied in a core from the southeastern Arabian Sea containing records of the past 70 ka. Palaeoproductivity proxies such as organic carbon (C ... -
Antimicrobial lipids from the hemolymph of brachyuran crabs
(Springer, 2010)The potential of marine crabs as a source of biologically active products is largely unexplored. In the present study, antimicrobial activity of the hemolymph (plasma) and hemocytes (plasma cells) of six brachyuran crabs ... -
A century of climate variability in central Dronning Maud Land, East Antarctica, and its relation to Southern Annular Mode and El Nino-Southern Oscillation
(American Geophysical Union, 2010)Stable isotope records of oxygen and hydrogen were studied from a 65 m long ice core retrieved from central Dronning Maud Land, East Antarctica, in order to reconstruct the coastal Antarctic climate variability during the ... -
Response of meiofauna to petroleum hydrocarbon of three fuel oils
(National Academy of Sciences, India, 2010)Oil spills are recurrent problem in marine system. Effects of oil pollution are many. The present paper evaluates the effect of Petroleum Hydrocarbon of three fuel oils on metazoan meiofauna. The results suggest significant ... -
Sea level changes induced by local winds on the west coast of India
(Springer, 2010)The contribution of atmospheric pressure and local wind to sea level variability at Goa (West coast of India) for the period 2007–2008 is investigated. Sea level data from a tide gauge are compared with measured local ... -
Correlation of the oldest Toba Tuff to sediments in the central Indian Ocean Basin
(Indian Academy of Sciences, 2010)We have identified an ash layer in association with Australasian microtektites of approx. 0.77Ma old in two sediment cores which are approx. 450 km apart in the central Indian Ocean Basin (CIOB). Morphology and chemical ... -
Distribution of dissolved carbohydrates and uronic acids in a tropical estuary, India
(Indian Academy of Sciences, 2010)Carbohydrates including uronic acids are among the active components of dissolved organic carbon, and play an important role in biogeochemical cycling of organic carbon in marine environments. In order to understand their ... -
Biological and environmental characteristics of mangrove habitats from Manori creek, West Coast, India
(Springer, 2010)Mumbai, a megacity of India, and its adjacent marine environment, though heavily stressed from various anthropogenic interferences, harbor approx. 146 km sup(2) of mangrove cover. Manori creek, in the close vicinity of ... -
Changes in the abundance and composition of zooplankton from the ports of Mumbai, India
(Springer, 2010)Zooplankton abundance, biomass, and composition from the ports of Mumbai, India, were studied by selecting 14 stations in and around the area during three different periods between 2001 and 2002 (Nov 01, Apr 02, and Oct ... -
Nutrient characteristics of the water masses and their seasonal variability in the eastern equatorial Indian Ocean
(Elsevier, 2010)Nutrient characteristics of four water masses in the light of their thermohaline properties are examined in the eastern Equatorial Indian Ocean during winter, spring and summer monsoon. The presence of low salinity water ... -
Oceanic and atmospheric influences on the variability of phytoplankton bloom in the southwestern Indian Ocean
(Elsevier, 2010)The phytoplankton bloom developed in the southwestern Indian Ocean during austral summer is unique in its occurrence. Interannual and intraannual variability of this large phytoplankton bloom were studied using satellite ... -
A possible medieval lighthouse at Mul Dwarka (Kodinar) Saurashtra Coast, India
(The Nautical Archaeology Society, 2010)An ancient lighthouse was observed during recent archaeological explorations at Mul Dwarka (Kodinar), which might be the oldest lighthouse so far recorded on the Saurashtra coast. This lighthouse, locally known as Diva ... -
