Seafloor spreading magnetic anomalies south off Sri Lanka
(Elsevier, 2006)Results obtained from compilation and reinterpretation of about 21,200 line km of bathymetry, magnetic and satellite gravity data between 10oS to 10oN latitudes and 75 to 90oE longitudes south off Sri Lanka are presented ... -
Studies on the pore water sulfate, chloride and sedimentary methane to understand the sulfate reduction process in the eastern Arabian Sea
(Indian Academy of Sciences, 2006)Sediment cores (~5 m length) from ten stations collected in the water depths of 2665-3210 m in the eastern Arabian Sea were studied for pore water sulfate (SO42-), chloride (Cl-) and lighter-hydrocarbons (methane: C1, ... -
The terrace like feature in the mid-continental slope region off Trivandrum and a plausible model for India-Madagascar juxtaposition in immediate pre-drift scenario
(Elsevier, 2006)Bathymetry of the southwestern continental margin of India reveal the presence of an anomalous terrace like feature in the mid continental slope region off Trivandrum. The genesis of this terrace of large areal extent ... -

Factors affecting the occurrence of Porphyra vietnamensis Tanaka & Pham-Hoang Ho along the Goa coast
(Indian Academy of Sciences, 2005)Porphyra vietnamensis Tanaka & Pham-Hoang Ho occurs in the intertidal region of the Goa coast, during mon-soon months from June to September. The growth and distribution patterns of P. vietnamensis populations along the ... -
Tsunamis: A large-scale earth and ocean phenomena
(Indian Academy of Sciences, 2005)Tsunamis are surface gravity waves that are triggered due to perturbation of the ocean floor. The tsunamis that occurred in the Indian Ocean on 26 December 2004 were due to an earthquake off the coast of Sumatra. Sea level ... -
Biological productivity, terrigenous influence and noncrustal elements supply to the Central Indian Ocean Basin: Paleoceanography during the past approx. 1 Ma
(Indian Academy of Sciences, 2005)A 2 m-long sediment core from the siliceous ooze domain in the Central Indian Ocean Basin (CIOB; 13 degrees 03'S: 74 degrees 44'E; water depth 5099 m) is studied for calcium carbonate, total organic carbon, total nitrogen, ... -
Compositional variation and genesis of ferromanganese crusts of the Afanasiy-Nikitin Seamount, Equatorial Indian Ocean
(Indian Academy of Sciences, 2005)Eight ferromanganese crusts (Fe-Mn crusts) with igneous and sedimentary substrates collected at different water depths from the Afanasiy-Nikitin Seamount are studied for their bulk major, minor and rare earth element ... -
Seasonal variability of physico-chemical characteristics of the Haldia channel of Hooghly estuary, India
(Indian Academy of Sciences, 2005)Physical and chemical characteristics of the Hooghly estuary during winter (December 1997 January 1998), summer (May 1998) and post-monsoon (November 1998) seasons have been studied. Salinity varied spatially and temporally ... -
Modelling Ballast Water Transport
(National Institute of Oceanography, Goa., 2002)Ballast water discharges in the coastal environs have caused a great concern over the recent periods as they account for transporting marine organisms from one part of the world to the other. The movement of discharged ... -
Breathing Cochin backwaters: Need for conservation
(National Institute of Oceanography, Goa., 2002)The foregoing account, it is evident that Vembanad Lake, including the Cochin backwaters is undergoing man-made shrinkage, at an alarming rate and a rough estimate of similar plans in the future shows that by the turn ... -
Butyltin compounds in biofilm and marine organisms from the Dona Paula Bay, west coast of India
(TERI Press, India, 2006)Biofilm, fish, oyster, mussel, and clams were collected from the Dona Paula Bay, west coast of India. These samples were analysed for butyltin derivatives. In the Dona Paula Bay, total butyltins varied from 21 to 89 ng/l ... -
Harmful algal blooms
(TERI Press, India, 2006)Phytoplankton or micro-algae play a vital role as primary producers in all aquatic habitats, but when their population overwhelms other forms of aquatic life, an environmental and economic impact is likely. Very prominent ... -
Overexploitation of fishry resources, with particular reference to Goa
(TERI Press, India, 2006)Marine living resources are not infinite. Overexploitation is a pervasive problem in fishery the world over. Landings of major fisheries resources in the Indian Ocean region have declined significantly, and the Goan coast ... -
A perspective of marine bioinvasion
(TERI Press, India, 2006)Bioinvasions are generally taken note of only when their impacts are felt. The impacts directly experienced by the society can be economical (loss of fishery or water as a resource) and human health related (for example, ... -
Metal and antibiotic-resistance in psychrotrophic bacteria from Antarctic marine waters
(Springer, 2006)In the wake of the findings that Antarctic krills concentrate heavy metals at ppm level, (Yamamoto et al., 1987), the Antarctic waters from the Indian side were examined for the incidence of metal and antibiotic-resistant ... -

The 2004 Indian Ocean tsunami: Description of the event and estimation of length of the tsunami source region based on data from Indian tide gauge
(The Institution of Engineers; Malaysia, 2006)The Great Tsunami of 26 December 2004 in the Indian Ocean is described using data from tide gauges along the coast of India. The tsunami struck the Indian east coast around 0330 UTC. The amplitude was 2.0 m above the tide ... -
Assessment of Godavari estuarine mangrove ecosystem through trace metal studies
(Elsevier, 2006)Trace metals (Fe, Mn, Cu, Co, Ni. Pb, Cd & Cr) analyses in particulate matter and sediments were carried out at sixteen different stations in the Godavari mangrove ecosystem covering the three regions viz., Kakinada (KKD) ...
