Taluka level environmental sensitivity index (ESI) and vulnerability mapping for oil spills: A pilot study from Goa state, India
(Sultan Qaboos Univ., 2010)Coastlines are at risk when floating oil slicks reach the shoreline. Oil spill causes major stress on the marine environment. To deal with oil spill problem in the coastal area, Environmental Sensitivity Index (ESI) maps ... -
Impact of water quality changes on harbour environment due to port activities along the west coast of India
(Sultan Qaboos Univ., 2010)Physico-chemical and biological studies were carried out in 3 major harbours (Kandla, Mormugao and Mangalore) along the west coast of India over different periods from 2002 to 2007. R-mode factor analyses, water quality ... -
Hydrodynamic changes due to large seabed installations in coastal waters off west coast of India
(Sultan Qaboos Univ., 2010)Offshore marine environment can very well be utilized for mass storage of liquids which are not harmful to that environment. Improper placement of large tanks on the seabed, to store large quantities of liquids, would ... -
A review on deep-sea fungi: Occurrence, diversity and adaptions
(Walter de Gruyter, 2010)The few studies on deep-sea fungi in recent years (using either culturing or molecular signatures) have provided evidence on their occurrence. A majority of culture-dependent and culture-independent fungi recovered have ... -
Seaward dipping reflectors along the SW continental margin of India: Evidence for volcanic passive margin
(Indian Academy of Sciences, 2010)Multi-channel seismic reflection profiles across the southwest continental margin of India (SWCMI) show presence of westerly dipping seismic reflectors beneath sedimentary strata along the western flank of the Laccadive ... -
New perceptions of continrntal margin biodiversity
(Blackwell, 2010)The deep ocean is a hostile and challenging environment. Nowhere is this more apparent than on the continental slopes. The complexity of the slope and the unforgiving nature of the seabed has until recently limited the ... -
Trace metal dynamics in zooplankton from the Bay of Bengal during summer monsoon
(Wiley Periodicals, Inc., 2010)Trace metal (Fe, Co, Ni, Cu, Zn, Cd, and Pb) concentrations in zooplankton from the mixed layer were investigated at 8 coastal and 20 offshore stations in the western Bay of Bengal during the summer monsoon of 2003. The ... -
Preference of echo features for classification of seafloor sediments using neural networks
(Springer, 2010)Selection of a set of dominant echo features to classify seafloor sediments using a multilayer perceptron neural network is investigated at two acoustic frequencies (33 and 210 kHz). Several sets of inputs with different ... -
Simulation of coastal winds along the central west coast of India using the MM5 mesoscale model
(Springer, 2010)A high-resolution mesoscale numerical model (MM5) has been used to study the coastal atmospheric circulation of the central west coast of India, and Goa in particular. The model is employed with three nested domains. The ... -
Morphology of pockmarks along the western continental margin of India: Employing multibeam bathymetry and backscatter data
(Elsevier, 2010)This study addresses the morphology of pockmarks along the western continental margin of India using multibeam bathymetry and backscatter data. Here, for the first time we have utilized the application of ArcGIS (Geographical ... -
Image analysis of seafloor photographs for estimation of deep-sea minerals
(Springer, 2010)Factors such as non-uniform illumination of seafloor photographs and partial burial of polymetallic nodules and crusts under sediments have prevented the development of a fully automatic system for evaluating the distribution ... -
Importance of upper ocean heat content in the intensification and translation speed of cyclones over the Bay of Bengal
(Current Science Association, 2010)An attempt has been made to examine the relationship between UOHC and Uh for the severe cyclones during 1990-2006. Uh has been computed from 6 h track positions of each storm (www.imd.gov.in; T3.0 onwards) and the corresponding ... -
First record of Hyalascus (Hexactinellida: Rossellidae) from the Indian Ocean, with description of a new species from a volcanic seamount in the Andaman Sea
(Magnolia Press, 2010)A new species of Hyalascus is described from the submarine volcanic crater seamount of Andaman Back-arc Basin, Indian Ocean. The genus was previously known in the Pacific Ocean only -
Isolation and characterization of novel plant growth promoting Micrococcus sp NII-0909 and its interaction with cowpea
(Elsevier, 2010)A phosphate-solubilizing bacterial strain NII-0909 isolated from the Western ghat forest soil in India was identified as Micrococcus sp on the basis of phenotypic characteristics, carbon source utilization pattern, fatty ... -
Sponge-associated bacteria of Lakshadweep coral reefs, India: resource for extracellular hydrolytic enzymes
(Scientific Research Publishing, 2010)Sponges (Phylum: Porifera) is one of the major groups in the Lakshadweep coral reefs. These sponges harbor diverse bacteria with metabolic potentiality. From biodiversity to biotechnological prospecting, scientific ... -
Free radical scavenging potential, reducing power, phenolic and biochemical constituents of Porphyra species from India
(PHYCOSPECTRUM INC, 2010)Inorganic elements, organic composition and antioxidant properties of Porphyra indica and P. veiatnamensis, were investigated. Heavy metals were found below toxic level, protein and ash contents were found to be the most ... -
