Algorithms and interface for ocean acoustic ray-tracing (Developed in MATLAB)
(National Institute of Oceanography, 2005)An integrated friendly-user interactive ocean application package has been developed for computation of eigenrays for a given source - receiver configuration and subsurface and bottom environmental conditions utilizing the ... -
An evaluation of physical and biogeochemical processes regulating perennial suboxic conditions in the water column of the Arabian Sea
(American Geophysical Union, 2002)Monthly oxygen budgets for the subsurface Arabian Sea (100-1000 m) are constructed on the basis of Modular Ocean Model and recently collected oxygen data. The model results are in agreement with the observed pattern. The ... -
An evaluation of physical and biogeochemical processes regulating the oxygen minimum zone in the water column of the Bay of Bengal
(American Geophysical Union, 2002)Monthly oxygen budgets for the intermediate waters (100-1000 m) of the Bay of Bengal were constructed based on Modular Ocean Model (MOM) and oxygen data. The model results reveal that the oxygen levels in the oxygen minimum ... -
Antibacterial activity of the sponge Ircinia ramosa: Importance of its surface-associated bacteria
(Springer, 2000)Variations in the antibacterial activity of the sponge Ircinia ramosa were evaluated during two collection periods (January and May) against vicinity fouling bacteria (VFB) and sponge surface-associated bacteria (SAB). The ... -
Assimilation potential of water column biota: Mesocosm-based evaluations
(Tata Energy Research Institute, India, 2003)This chapter presents a generalized picture of various aspects of assimilation by native biota and underscores the importance of safeguarding the environment from excessive discharge of nutrient-rich effluents, even though ... -
Baseline studies and evaluation of effects of surface discharge of deep-sea mining - INDEX area
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Hydrochemical properties of the water column were measured at the Indian Experiment (INDEX) site in the Central Indian Ocean Basin, as a part of baseline studies for the environmental impact assessment of benthic disturbance. ... -
Bathymetric distribution of Pleuromamma (Copepoda, Calanoida) species in the Indian Ocean
(ICAR, New Delhi, 1991)Based on the analysis of 204 zooplankton samples from the stratified depths in the Indian Ocean collected during the International Indian Ocean Expedition (IIOE), the distribution of the genus Pleuromamma indica, P. gracilis, ... -
Biological characteristics of Central Indian Basin waters during the southern summer
(Taylor and Francis, 2005)Phytoplankton biomass, taxonomy, primary productivity, and photosynthetically available radiation (PAR) were studied as part of baseline data collection for prospective nodule mining in the Central Indian Basin during the ... -
Boron-Chlorinity Relationship in Western Bay of Bengal
(CSIR-NISCAIR, 1981)Significant scatter in B/Cl beyond the limit of experimental error indicates that the ratio is not truly constant. B/Cl maximum, centred around 100 m, appears to be influenced by colloidal and particulate matter while the ... -
Characteristics of coastal waters of the western Bay of Bengal during different monsoon seasons
(CSIRO, Australia, 1992)Physical characteristics of waters along the eastern coast of India up to offshore distances of 400 km have been investigated during the seasons of the north-easterly and south-westerly monsoons in light of relevant observed ... -
Chemical characteristics of Central Indian Basin waters during the southern summer
(Pergamon, 2001)Chemical properties of the water column were examined at the Indian Deep-sea Environment Experiment (INDEX) site in the Central Indian Basin (CIB), as a part of baseline studies prior to the benthic disturbance experiment ... -
Dinoflagellate cyst assemblages in recent sediments of Visakhapatnam harbour, east coast of India: Influence of environmental characteristics
(Elsevier, 2013)The distribution and abundance of dinoflagellate cysts in recent sediments from Visakhapatnam harbour, east coast of India was investigated and compared with sediment characteristics and physico-chemical variables of the ... -
Dissolved organic carbon in the INDEX area of the Central Indian Basin
(Pergamon, 2001)Dissolved organic carbon (DOC) concentrations at the Indian Deep-Sea Environment Experiment (INDEX) site of the Central Indian Basin can be divided into three depth intervals. The subsurface layer (25-200 m) shows highly ... -
Distribution and abundance of pelagic shrimps from the deep scattering layer of the eastern Arabian Sea
(The National Shellfisheries Association, 2006)The sonic scattering layer (SSL) or deep scattering layer (DSL) of the eastern Arabian Sea of India is found in depths between surfaces to 750 m with varying thicknesses and in multiple layers. There is a distinct resident ... -
Distribution of calanoid copepods in the Arabian sea and Bay of Bengal
(Indian Association for Limnology and Oceanography, 1984)The distribution of calanoid copepods from the northern Arabian Sea and Bay of Bengal is discussed in relation to thermocline. The inshore offshore zonation of a neritic, shelf an oceanic communities was traced based on ... -
Distribution of particulate carbohydrate in the eastern Arabian sea along 15 (degrees) N
(CSIR-NISCAIR, 1988)The concentration of particulate carbohydrate varied from 38-158 mu g.l-1 and 19-239 mu g.l-1 in shelf and slope waters respectively. At 10 m water column the concentration of particulate carbohydrate increased with the ... -
Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
(Inter-Research, 2004)Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ... -
Docosahexaenoic acid accumulation in hraustochytrids: Search for the rationale
