Characterizing the estuarine riverbed using acoustic technique
(IEEE, 2010)Single transact of multi-beam bathymetry and backscatter data is acquired from Mandovi estuary of Goa, India for three days during the pre-monsoon session. The measurements were made during the high tide. In this work, ... -
Integrated Coastal Observation Network (ICON) for real-time monitoring of sea-level, sea-state, and surface-meteorological data
(IEEE, 2010)National Institute of Oceanography (NIO), Goa, India has established an Integrated Coastal Observation Network (ICON) of in-house designed and developed Internet-accessible real/near-real time reporting cellular based ... -
First nodule to first mine-site: Development of deep-sea mineral resources from the Indian Ocean
(Current Science Association, 2010)Polymetallic nodules found on the deep seafloor (> 4000 m water depth) have been recognized as an alternative source for certain metals, when land deposits get exhausted. Spread over millions of square kilometres on the ... -
Occurrence of cyanobacteria - diatom symbiosis in the Bay of Bengal: Implications in biogeochemistry
(Current Science Association, 2010)Diazotrophs (N sub(2) fixing organisms), mainly belonging to cyanobacteria, form a major group of phytoplankton in nutrient poor oligotrophic oceans. These organisms support non-diazotrophic phytoplankton community and ... -
Response of coastal vegetation and the need for green belts along the Tamil Nadu coast, India: The December 2004 tsunami experience
(Nova Science Pub., 2010)The Indian Ocean tsunami of December 2004 transmitted multiple lessons: whereas certain strips were destroyed in totality, others remained unaffected or practically intact. Detailed post-tsunami field surveys conducted ... -
Building digital collections: An evaluation
(DELNET, 2010)The difference between 'digital collection' and 'digital library' has been explained. The evaluation parameters for digital collections are described. These are based on the basic principles of the digital collection. The ... -
Impact of sewage disposal on a nematode community of a tropical sandy beach
(Triveni Enterprises, 2010)Free-living marine nematodes from an intertidal sandy beach from Goa near the Panjim city, central west coast of India was investigated along a gradient of sewage pollution. High nematode diversity (11 species) and abundance ... -

Bathymetric highs in the mid-slope region of the western continental margin of India - Structure and mode of origin
(Elsevier, 2010)Analysis of the multi- and single beam bathymetric, seismic, magnetic and free-air gravity (ship-borne and satellite derived) data from the western continental margin of India between 12 degrees 40 minutes N and 15 degrees ... -
Dispersion and retrievability of water quality indicators during tidal cycles in coastal Salaya, Gulf of Kachchh (West coast of India)
(Springer, 2010)Bacterial indicators in relation to tidal variations were studied at five locations for over 2 days covering three tidal cycles in the southwestern region of Gulf of Kachchh, India. Tidal flow here is predominantly in the ... -
New geological-geophysical data on the structure of the Ninetyeast Ridge
(Pleiades Publishing, 2010)The Ninetyeast (or East Indian) Ridge is one of the longest aseismic volcanic ridges in the World Ocean and one of the longest linear structures of the Earth. It is 200 km wide on average, and it extends in the meridional ... -
Role of iron deficiency in production and remineralization of organic matter in the Arabian Sea
(Solas, 2007)The Arabian Sea contains the only major western-boundary upwelling system in the world's oceans During summer, strong southwesterly winds bring up subsurface waters from depths of up to 200m off Somalia, Yemen and Oman ... -
Sources of organic matter and microbial community structure in the sediments of the Visakhapatnam Harbour, east coat of India
(Elsevier, 2010)Organic matter in the coastal sediments originates from various terrestrial and marine sources. Within the sampling sites, relative inputs from these sources may vary and can influence the microbial community structure. ... -
Larval development, sensory mechanisms and physiological adaptions in acorn barnacles with special reference to Balanus amphitrite
(Elsevier, 2010)Barnacles have drawn the attention of many naturalists and often dominate fouling communities. Balanus amphitrite, is a shallow water acorn barnacle capable of inhabiting expanses from supralittoral to subtidal levels, and ... -
