Effect of an oil spill from MV Sea Transporter on intertidal meiofauna at Goa, India
(Pergamon, 2002)Short and long term effects of a fuel oil spill from a grounded ship "MV Sea Transporter" on meiofauna of a sandy beach of North Goa at Sinquerim and adjacent Cadolim and Calangute beaches along the central West Coast of ... -
On the nature of the calcareous substrate of a ferromanganese crust from the Vityaz Fracture Zone, Central Indian Ridge: Inferences on palaeoceanography
(Springer, 2002)A 15-cm-thick carbonate substrate encrusted with ferromanganese oxides from the Vityaz Fracture Zone, Central Indian Ridge was analysed to reconstruct the palaeoceanography of the region. Based on the calcareous nannoplankton ... -
The Mysidacea of the Andaman Sea
(Oxford Univ Press, 2002)Fifteen species belonging to eight genera were collected from the shallow waters (0-150 m) of the Andaman Sea. Of thee one species Doxomysis nicobaris is described as new and all the other species are identified with ... -
Upper ocean stratification and circulation in the northern Bay of Bengal during southwest monsoon of 1991
(Pergamon, 2002)During the southwest monsoon (July) of 1991 a large plume (300 x 250 km sup(2)) of warm (greater than 29 degrees C) and less saline (less than 29 PSU) water is noticed in the top 30 m to the east of 87.5 degrees E in the ... -
Export fluxes of dimethylsulfoniopropionate and its break down gases at the air-sea interface
(American Geophysical Union, 2002)Dimethylsulfide (DMS) results from the decomposition of dimethylsulfoniopropionate (DMSP), a biogenic product, in seawater. Diffusive transfer of DMS from sea-to-air is known to be the most important source of natural ... -
Analysis of sup(210)Pb in sediment trap samples and sediments from the northern Arabian Sea: Evidence for boundary scavenging
(Pergamon, 2002)The concentrations of sup(210)Pb were measured in particles intercepted by sediment traps deployed at 1024 m and 3024 m in the northern Arabian Sea for a period of 1 year from November 1986 to October 1987. The sup(210)Pb ... -
Analyses of multichannel seismic reflection, gravity and magnetic data along a regional profile across the central-western continental margin of India
(Elsevier, 2002)Analysis of multichannel seismic reflection, gravity, magnetic and bathymetry data along a regional profile across the central-western continental margin of India have revealed the depositional pattern of sediments, crustal ... -
Mangrove ecosystem of India: Conservation and management
(Pointer Publ.; Jaipur; India, 2002)Mangroves are distributed to the lower latitude (32 degrees S - 3 degrees N) in the tropical regions. The maximum diversity and area cover lies in the regions between 25 degrees S - 25 degrees N. These habitats are ... -
A neural network based seafloor classification using acoustic backscatter
(Springer-Verlag; Berlin, Heidelberg, 2002)This paper presents a study results of the Artificial Neural Network (ANN) architectures [Self-Organizing Map (SOM) and Multi-Layer Perceptron (MLP)] using single beam echosounding data. The single beam echosounder, operable ... -
Estimating deep seafloor interface and volume roughness parameters using the multibeam-hydrosweep system
(Taylor & Francis, 2002)Utilizing a hull-mounted, multinarrow beam echosounder onboard RV Polarstern, variation of acoustic backscatter with incidence angles at two different sites in the Southern Oceans (Agulhas Plateau and the Riiser Larsen ... -
Pyramidal anchor stone from Baga waters of Goa, west coast of India
(The Society for Nautical Research, 2002)Underwater exploration in the coastal region off Baga (Goa, India) led to the recovery of an isolated stone artefact, which resembles a pyramidal type of anchor stone. This anchor stone is unlike to other pyramidal anchor ... -
Quaternary phosphorites off the southeast coast of India
(Elsevier, 2002)Detailed petrological, mineralogical, geochemical and radiogenic (U, Sr, Nd) and stable isotope (C, O, S) studies have been carried out on the Quaternary phosphorites of the continental margin off Chennai, southeast coast ... -
Bacterial flora associated with larval rearing of the giant freshwater prawn, Macrobrachium rosenbergii
(Elsevier, 2002)Quantitative and qualitative analyses of bacterial flora associated with larval rearing of the giant freshwater prawn, Macrobrachium rosenbergii, along with important water quality parameters, were carried out over a larval ... -
Diatoms of the microphytobenthic community: Population structure in a tropical intertidal sand flat
(Springer, 2002)Temporal and spatial variations were investigated in the viable diatom population of the microphytobenthic community from an intertidal sand flat of a tropical environment. The presence of diatoms to a sediment depth of ... -
Marine archaeological research in India
(Manohar Publishers and Distributers; New Delhi (India), 2002)Marine archaeology is otherwise known as maritime, nautical or underwater archaeology. These terms include all aspects of marine archaeology in which water plays a dominant role. It deals with the study of past seafaring ... -
Pyloniid stratigraphy - A new tool to date tropical radiolarian ooze from the central tropical Indian Ocean
(Elsevier, 2002)Pyloniid stratigraphy, a faunal abundance-variation stratigraphic tool, similar to Cycladophora davisiana stratigraphy employed at high latitudes, is found to work well for tropical radiolarian ooze. The relationship between ... -
Barium as a productivity proxy in continental margin sediments: A study from the eastern Arabian Sea
(Elsevier, 2002)Barium, aluminium, cadmium and uranium were analyzed in 112 surface sediment samples from the western continental margin, of India. Excess Ba (Ba sub(xs)) concentrations are high at the SW margin of India, an area of high ... -
Over-estimation of sea level measurements arising from water density anomalies within tide-wells - A case study at Zuari Estuary, Goa
(The Coastal Education and Research Foundation, 2002)A 3-year study of water density anomalies within a conventional tide-well indicated that the average water density within the well was consistently lower than that of the external ambient waters. The tide-well at Marmugao, ... -
Antifouling potential of some marine organisms from India against species of Bacillus and Pseudomonas
(Springer, 2002)Crude methanolic extracts of 37 marine organisms (16 species of flora, 21 species of fauna) were screened for antibacterial properties against 5 strains of bacteria isolated from marine environments. Of these, 10 plant and ... -
