Can undersea voltage measurements detect tsunamis?
(Terrapub, 2010)The movement of electrically conducting ocean water in the ambient geomagnetic field induces secondary electric and magnetic fields in the oceans. Ocean water transport is now routinely inferred from undersea cable voltage ... -
Ilmenite, magnetite and chromite beach placers from south Maharashtra, central west coast of India
(The Society of Resource Geology, 2010)The heavy mineral placer deposits of the coastal sediments in south Maharashtra stretch for 12.5 km from Pirwadi in the north to Talashil in the south. The area is a sand bar represented by a narrow submergent coastal plain ... -
Evaluation of the CaCO3 dissolution proxies in sediment cores from above the lysocline
(Elsevier, 2010)Calcium carbonate analyses were carried out from two size fractions (less than 63 mu m and more than 63 mu m) from the Ocean Drilling Program Sites 752 and 715 collected from above the lysocline depth in the Indian Ocean, ... -
Signatures of global warming and regional climate shift in the Arabian Sea
(Cochin University of Science and Technology, 2010)The impact of global warming in the recent decade is shown by the disruption in the natural decadal cycle in the sea surface temperature (SST) of the Arabian Sea after 1995. We propose a regional climate shift after 1995, ... -
Seasonal mixed layer heat balance of the southwestern tropical Indian Ocean
(American Meteorological Society, 2010)Sea surface temperature (SST) in the southwestern tropical Indian Ocean exerts a significant influence on global climate through its influence on the Indian summer monsoon and Northern Hemisphere atmospheric circulation. ... -
Association of the stramenopilan protists, the aplanochytrids, with zooplankton of the equatorial Indian Ocean
(Inter-Research, 2010)Thraustochytrids and aplanochytrids, belonging to the Labyrinthulomycetes of the Kingdom Stramenopila, have been frequently reported to occur as parasites or symbionts in a number of coastal invertebrates. Given the fact ... -
Phylogenetic diversity of culturable fungi from the deep-sea sediments of the central Indian Basin and their growth characteristics
(Kunming University of Science and Technology, 2010)Very few studies have addressed the diversity of culturable fungi from deep-sea sediments. We are reporting here the diversity of culturable fungi in deep-sea sediments of the Central Indian Basin obtained from a depth of ... -
The contribution of deep-sea macrohabitat heterogeneity to global nematode diversity
(Blackwell Verlag GmbH, 2010)The great variety of geological and hydrological conditions in the deep sea generates many different habitats. Some are only recently explored, although their true extent and geographical coverage are still not fully ... -
Four marine-derived fungi for bioremediation of raw textile mill effluents
(Elsevier, 2010)Textile dye effluents pose environmental hazards because of color and toxicity. Bioremediation of these has been widely attempted. However, their widely differing characteristics and high salt contents have required ... -
Formation of hydrothermal deposits at Kings Triple Junction, northern Lau back-arc basin, SW Pacific: The geochemical perspectives
(Elsevier, 2010)An inactive hydrothermal field was discovered near Kings Triple Junction (KTJ) in northern Lau back-arc basin during 19th cruise of R/V Akademik Mstislav Keldysh in 1990. The field consisted of a large elongated basal ... -
Minima of interannual sea-level variability in the Indian Ocean
(Elsevier, 2010)Wavelet analysis of altimeter sea level in the Indian Ocean shows regions of high variability (maxima) and low variability (minima) at all time scales. At interannual time scales, i.e., at periods of 17 months or more, ... -
Macrofaunal community structure in the western Indian continental margin including the oxygen minimum zone
(Blackwell Verlag GmbH, 2010)Patterns of macrofaunal distribution were studied along the western Indian continental margin to distinguish the role of habitat heterogeneity in generating and maintaining community structure. A transect perpendicular to ... -
Exploration and utilization of energy from sea
(S.N. Arts, D.J.M. Commerce and B.N.S. Science College, 2010)The major sources of energy at present are hydrocarbons (oil, gas and coal), hydroelectric power, and nuclear power. We need to seek alternate sources because of several reasons such as threat of depletion of existing ... -
Land-ocean tectonic signatures of the Krishna-Godavari Basin, a qualitative evaluation
(Current Science Association, 2010)The bathymetry data of Krishna-Godavari Offshore Basin reveal that the water depths in the area vary from 40 m (near shore) to 3000 m (offshore). The data indicate high gradient tightly packed contours over offshore Krishna ... -
Seismic structure and tectonics of the continental margins of India
(Professional Books, 2010)In this chapter we have discussed and synthesized the last 15 years marine geophysical research work on Indian continental margins and adjoining oceanic regions carried out at National Institute of Oceanography, Goa India). ... -
Instrumental, terrestrial and marine records of the climate of South Asia during the Holocene: Present status, unresolved problems and societal aspects
(Capital Publishing Co., 2010)A key societal aspect is to recognize the factors controlling the spatial variability and the distribution patterns of rainfall in a season, and its long as well as short term variability due to natural factors. We archive ... -
Ghogha: An Indo-Arabian Trading Post in the Gulf of Khambhat (Cambay), India
(The Nautical Archaeology Society, 2010)The ancient port of Ghogha is situated on the western bank of the Gulf of Khambhat, which has the highest tidal range in India, and the remains of the oldest civilization. Recent marine archaeological explorations in this ... -
Exploration of a steamship wreck off Amee shoals, Goa, India: A preliminary report
(The Nautical Archaeology Society, 2010)Recent explorations off Amee shoals, Goa, have brought to light the remains of a steel-hulled steam-engine shipwreck, scattered over a large area. Though sparse and heavily salvaged, this site represents the first discovery ... -
The life cycle of the free-living marine nematode Innocuonema tentabunda De Man 1890
