Link between convection and meridional gradient of sea surface temperature in the Bay of Bengal
(Indian Academy of Sciences, 2007)We use daily satellite estimates of sea surface temperature (SST) and rainfall during 1998-2005 to show that onset of convection over the central Bay of Bengal (88-92E, 14-18N) during the core summer monsoon (mid-May to ... -
Vertical propagation of baroclinic Kelvin waves along the west coast of India
(Indian Academy of Sciences, 2007)A linear, continuously stratified ocean model is used to investigate vertical propagation of remotely forced, baroclinic Kelvin waves along the Indian west coast. The extent of vertical propagation over the length of the ... -
A petrogenetic model of basalts from the Northern Central Indian Ridge: 3-11°S
(Geological Society of China, 2007)Mid-Ocean Ridge Basalts (MORB) from Northern Central Indian Ridge (NCIR) were recovered between latitudes 30 and 110S and are olivine tholeiite with higher abundances of K and Rb. They are of typical transitional MORB ... -
Deep-sea fungi: Occurrence and adaptations
(2006)Fungi in the marine environment have only been fully recognized since about 1960, and within the group, marine fungi have shown highest decadal indices (% increases in species number over a 10 year period) with respect of ... -
A tropical warm pool in the Indian Ocean and its influence on ENSO over the past 137, 000 yrs BP
(Indian Academy of Sciences, 2007)The tropical sea surface temperature (SST) is one of the important factors that regulates the amount and duration of rainfall in the tropical region, the world’s most densely populated region. The tropical oceanic warm ... -
Shark hunting - An indiscriminate trade endangering elasmobranchs to extinction
(Indian Academy of Sciences, 2007)Shark finning - chopping-off the fins and discarding the rest - is increasing worldwide to satisfy the demand of shark-fin soup. This massive requirement for shark fins and other shark-related products has created an ... -
The small Maya AUV – Initial field results
(Underwater World Publications Ltd., 2007)A significant step in developing a prototype small AUV, called Maya, was achieved at the National Institute of Oceanography (NIO), Goa, India, in May 2006. The project received initial seed funding from NIO in 2003 and a ... -
Four new species of the genus Rhopalophthalmus (Mysidacea: Crustacea) from the northwest coast of India
(Taylor & Francis, 2006)Four species belonging to the genus Rhopalophthalmus - R. mumbayensis, R. anishi, R. murudana, R. vijayai - are described as new to science. All four species are distinguishable from each other and from other related species ... -
The west Andaman fault and its influence on the aftershock pattern of the recent megathrust earthquakes in the Andaman-Sumatra region
(American Geophysical Union, 2007)Distinctly different rupture patterns of December 2004 and March 2005 megathrust earthquakes occurred in the Andaman-Sumatra region suggest strong influence of tectonic and structural elements. We have analysed the shipboard ... -
Environmental analysis of heavy metal deposition in a flow-restricted tropical estuary and its adjacent shelf
(Taylor & Francis, 2006)The geochemical condition of surface sediments in a tropical estuary and adjoining shelf region is presented for their elemental interactions using statistical methods. Principal component analysis separated two clusters ... -
Persistent volcanic signature observed around Barren Island, Andaman Sea, India
(Springer, 2006)This study delineates the formation of a warm pool (> 33°C) of air to the west (downwind) of the active volcano of the Barren Island during October-November 2005. Barren Island is located in the Sumatra-Andaman region, ... -
Climate fluctuations of tropical coupled systems — The role of ocean dynamics
(American Meteorological Society, 2006)The tropical oceans have long been recognized as the most important region for large-scale ocean-atmosphere interactions, giving rise to coupled climate variations on several time scales. During the TOGA decade, the focus ... -
New bioactive hydrogenated linderazulene-derivatives from the gorgonian Echinogorgia complexa
(Elsevier, 2007)Chemical analysis of the secondary metabolite pattern of the gorgonian Echinogorgia complexa, collected along South Indian coasts, showed the presence of two new tricyclic guaiane furanosesquiterpenes, iso-echinofuran (3) ... -
Mother goddesses with boat motifs on stone sculptures from Goa
(CRTHAP, 2006)An onshore exploration along the tributaries of the river Madovi in taluka Sattari of North Goa district, revealed the presence of 8 sculptures of Mother Goddess with the boat motifs. Most of the sculptures are in very ... -
Marine archaeological explorations on the southwestern coast of Saurashtra, India
(CRTHAP, 2006)Marine archaeological investigations brought to light a large number of antiquities suggesting active maritime practices along the Saurashtra coast, Gujarat, India dating back to the Indus Valley Civilization. Recent ... -
Stability of a sand spit due to dredging in an adjacent creek
(Elsevier, 2007)The Jatadharmohan creek lies between Mahanadi and Devi Rivers along the Orissa coast and it is separated from the sea by an elongated sand spit. It was proposed to mine a volume of 15 x 10 sup(6) m³ of sand from the creek ... -
Bioremediation of toxic substances by mercury resistant marine bacteria
(Elsevier, 2006)Bioremediation of toxic substances includes microbe-mediated enzymatic transformation of toxicants to non-toxic, often assimilable, forms. Mercury-resistant marine bacteria are found to be very promising in dealing with ... -
Software for validating parameters retrieved from satellite
(The Indian Society of Remote Sensing, 2006)A PC-based interactive software has been developed and presented here for validating geophysical data retrieved from satellite mounted sensors operating in visible, infrared and microwave frequencies. The program, coded ... -
