Sulfur cycle
(Elsevier, 2008)Microbes, especially bacteria, play an important role in oxidative and reductive cycle of sulfur. The oxidative part of the cycle is mediated by photosynthetic bacteria in the presence of light energy and chemosynthetic ... -
How vulnerable is Indian coast to oil spills? Impact of MV Ocean Seraya oil spill
(Current Science Association, 2008)On 30 May 2006, a bulk carrier, MV Ocean Seraya ran aground along the Karwar coast spilling 650 tonnes of oil. Due to the rough SW monsoon, the spill spread to some beaches in south Goa. The aim of this communication is ... -
Impact of tropical cyclone on biogeochemistry of the central Arabian Sea
(American Geophysical Union, 2008)Remotely sensed data are combined with shipboard measurements to investigate biogeochemical changes caused by a moderate tropical cyclone in the central Arabian Sea in December 1998. The sea surface temperature decreased ... -
Water-column geochemical anomalies associated with the remnants of a mega plume: A case study after CR-2003 hydrothermal event in Carlsberg Ridge, NW Indian Ocean
(Current Science Association, 2008)Recently, an unusually large hydrothermal event (CR- 2003) was reported over the slow-spreading Carlsberg Ridge between 05 degrees 41 minutes N, 61 degrees 30 minutes E and 06 degrees 20 minutes N, 60 degrees 33 minutes ... -
Seasonal variations in the fouling diatom community structure from a monsoon influenced tropical estuary
(Taylor & Francis, 2008)Seasonal variations in the fouling diatom community from a monsoon influenced tropical estuary were investigated. The community composition did not differ significantly between stainless steel and polystyrene substrata due ... -
A cold pool south of Indo-Sri Lanka channel and its intrus on into the southeastern Arabian Sea during winter
(Elsevier, 2008)During winter, south of the Indo-Sri Lanka Channel (ISLC), the observed sea-surface temperature (SST) distribution shows a distinct mini-cold pool (MCP) with relatively cooler waters (SST is less than 28 degrees C). All ... -
Morphological changes at Vellar estuary, India - Impact of the December 2004 tsunami
(Elsevier, 2008)Coastal subsystems formed by interaction of various processes, impacted by natural hazards like tsunami and storms, pose irreversible morphological changes. Vellar estuary, located on the southeast coast of India, with ... -
Hydrography and biogeochemistry of the north western Bay of Bengal and the north eastern Arabian Sea during winter monsoon
(Elsevier, 2008)The north eastern Arabian Sea and the north western Bay of Bengal within the Indian exclusive economic zone were explored for their environmental characteristics during the winter monsoons of 2000 and 2001 respectively. ... -
Nutrient regimes and their effect on distribution of phytoplankton in the Bay of Bengal
(Elsevier, 2008)The seasonal dynamics of nutrient ratios and abundance of phytoplankton cells from the central (CB) and western (WB) Bay of Bengal (BOB) were studied during the fall intermonsoon (FIM; September-October 2002) and spring ... -
Post-tsunami changes in the littoral environment along the southeast coast of India
(Elsevier, 2008)The 26th December 2004 Indian Ocean tsunami devastated coastal regions of the Indian subcontinent. Andaman and Nicobar Islands, coastal stretches of Tamil Nadu, Andhra Pradesh and Kerala were the most affected regions of ... -
Impact of Irgarol 1051 on the larval development and metamorphosis of Balanus amphitirite Darwin, diatom, Amphora coffeaformis and natural biofilm
(Taylor & Francis, 2008)The effect of Irgarol 1051 on the biofilm-forming diatom, Amphora coffeaformis, and on natural biofilm was assessed. A reduction in the number of A. coffeaformis cells within a biofilm was observed after treatment with ... -

26th December 2004 great Sumatra-Andaman earthquake: Co-seismic and post-seismic motions in northern Sumatra
(Elsevier, 2007)Trench-parallel thrust faults verging both landward and seaward were mapped in the portion of wedge located between northern Sumatra and the Indian-Indonesian boundary The spatial aftershocks distribution of the 26th ... -
Maritime archaeology of Kalinga and the contact with southeast Asian countries
(Agam Kala Prakashan; Delhi (India), 2002)During the last five thousand years in the maritime history of India, Kaling played an important role in diffusing the Indian culture in Southeast Asian countries. Archaeological exploration and excavations, epigraphical ... -
XBT fall rate in waters of extreme temperature: A case study in the Antarctic Ocean
(American Meteorological Society, 2002)XBT fall-rate variation in waters of extreme temperature and the resulting depth error has been addressed using controlled XBT-CTD datasets collected from two cruises in the Southern Ocean. Mean depth errors deduced from ... -
Spatial distribution of upwelling off the central east coast of India
(Academic Press, 2002)The spatial distribution of upwelling along the central east coast of India (13 degrees-18 degrees N) in the premonsoon and south-west monsoon seasons is described using data collected during cruises 193 (13-28 March 1988) ... -
Genetic relationships among five nemipterid fish species from the Indian coast using allozyme analysis
(Elsevier, 2002)Based on Nei's genetic distance Nemipterus peronii and N. japonicus showed a greater affinity to Parascolopsis aspinosa than to the other Nemipterus species studied. Significant differences between the Indian west and east ... -
Carbon cycling in the northern Arabian Sea during the northeast monsoon: Significance of salps
(Inter-Research, 2002)Winter cooling and mixing brings nutrients (nitrate and phosphate) to the surface waters over large parts of the northern Arabian Sea, but the rates of primary production as well as carbon export from the euphotic zone are ... -
Analysis of wave directional spreading using neural networks
(ASCE, 2002)The short-term directional spreading of wave energy at a given location is popularly modeled with the help of the Cosine Power model. This model is oriented mainly around value of the spreading parameter involved in its ... -
Ocean bio-geophysical modeling using mixed layer-isopycnal general circulation model coupled with photosynthesis process
(Research Signpost; Trivandrum, Kerala; India, 2002)In the ocean mixed layer, phytoplanktons convert carbon dioxide into organic matter, which is accumulated into the body of phytoplankton, zooplankton, and fish communities. At the end of ocean biological food web, some ...
