Zooplankton studies with special reference to krill Euphausia superba Dana from fishing area 58 of Indian Ocean sector in Southern Ocean
(Indian Academy of Sciences, 2005)Distribution, abundance and species composition of zooplankton collected during the First Indian Antarctic Krill Expedition were studied. Zooplankton biomass values ranged from 9.79 to 303.62 ml 100 m sup(–3) (x bar = ... -
Role of marine algae in organic farming
(Indian Academy of Sciences, 2005)As the efforts to unearth new sources for organic farming accelerate, one needs to evaluate the options available. Marine algae popularly known as seaweeds, have served mankind from times immemorial. form. Seaweed-based ... -
Extremophilic microbes: Diversity and perspectives
(Indian Academy of Sciences, 2005)A variety of microbes inhabit extreme environments. Extreme is a relative term, which is viewed compared to what is normal for human beings. Extreme envi-ronments include high temperature, pH, pressure, salt concentration, ... -
Dealing with 26/12
(Indian Academy of Sciences, 2005)The >M9 earthquake of 26 December 2004 (26/12) that generated devastated tsunami was probably occurred by a combination of three tectonic movements- dip-slip at Sunda trench, strike-slip along the boundary between India ... -
Clay as indicator of sediment plume movement in deep-sea environment
(Indian Academy of Sciences, 2004)Future polymetallic nodules mining in the Central Indian Basin (CIB) will disturb not only the deep-sea sediments but also the benthic environment. Generation of voluminous sediment plume due to mining activity is unavoidable, ... -
Effect of salinity on larval growth of horseshoe crab, Tachypleus gigas (Muller)
(Indian Academy of Sciences, 2004)Growth of the trilobite larvae of Tachypleus gigas was studied at salinity ranging from 10 to 40 ppt. In terms of body weight, the growth was higher (232 plus or minus 7.5 mg/week) (P < 0.05) at 40 ppt salinity, and the ... -
Major turbidity flows in the Western Indus Fan between 290 and 360 kyr
(Indian Academy of Sciences, 2004)Calcium carbonate (CaCO sub(3)), aluminium (Al), titanium (Ti), and terrigenous matter analyses were carried on the Ocean Drilling Programme Site 720A from the Indus Fan in the Arabian Sea. CaCO3, Al, Ti and terrigenous ... -
Regeneration of gill lamellae of the Indian horseshoe crab, Tachypleus gigas (Muller)
(Indian Academy of Sciences, 2004)It has been a well-known fact that the crustaceans are able to re-grow their limbs and regenerate muscle fibers. In our experiment, about a third of the lost gill lamellae was observed to be regenerated on the 50th day and ... -
Algal blooms in the seas around India - Networking for research and outreach
(Indian Academy of Sciences, 2004)The ever-growing reports on harmful algal blooms (HABs), their adverse consequences on economy and the pace with which consortia of institutes are being formed globally to understand their dynamics, prompted us to view the ... -
Differential response of winter cooling on biological production in the northeastern Arabian Sea and northwestern Bay of Bengal
(Indian Academy of Sciences, 2004)The northern parts of the twin seas bordering the Indian subcontinent, the Arabian Sea (AS) and Bay of Bengal (BOB), were studied during the winter monsoon. Higher biological production was observed in the AS (chlorophyll ... -
Fluvial influx and weathering history of the Himalayas since Last Glacial Maxima - Isotopic, sedimentological and magnetic records from the Bay of Bengal
(Indian Academy of Sciences, 2004)From temporal variations in stable isotopes, mineral magnetism, clay minerals and granulometric parameters from a sup(14) C dated core have been used to understand weathering history and influence of climate on the terrigenous ... -
Abundance of pollution indicator and pathogenic bacteria in Mumbai waters
(Indian Academy of Sciences, 2004)As a part of environmental assessment in the Mumbai Harbour region, where large numbers of ships either take in ballast from- or discharge their ballast, many groups of indicator and human pathogenic bacteria were quantified. ... -
Manganese nodules as a possible source of precious metals
(Indian Academy of Sciences, 2004)Marine geochemistry of Platinum (Pt) and Iridium (Ir) shows that both the elements are relatively enriched in manganese nodules. Compared to Pt concentration in the earth's upper continental crust the oceanic manganese ... -
Validation of multi-channel scanning microwave radiometer on-board Oceansat-1
(Indian Academy of Sciences, 2004)Sea surface temperature (SST), sea surface wind speed (WS) and columnar water vapour (WV) derived from Multi-frequency Scanning Microwave Radiometer (MSMR) sensor on-board IRS-P4 (Oceansat-1) were validated against the in ... -
Wave characteristics off Visakhapatnam coast during a cyclone
(Indian Academy of Sciences, 2004)Waves were measured using a directional waverider buoy off Visakhapatnam, east coast of India during the passage of a cyclone in November 1998. The maximum wave height observed during the passage was 5.74 m, whereas this ... -
