A biweekly mode in the equatorial Indian Ocean
(American Geophysical Union, 2004)The National Institute of Oceanography, Goa, India, deployed moorings with several subsurface current meters at 0 degrees, 93 degrees E (in February 2000) and 0 degrees, 83 degrees E (in December 2000) in the eastern Indian ... -
A Comparative Study of Vertical Stabilities in the Arabian Sea and Bay of Bengal
(India Meteorological Department, 1981)Stabilities in the upper 300 m in the Arabian Sea and the Bay of Bengal are computed and presented seasonwise. The water column in the Bay of Bengal is more strongly stratified than that in the Arabian Sea. These studies ... -
Algal blooms: a perspective from the coasts of India
(Springer, 2012)Algal blooms have been documented along the west and east coasts of India. A review of bloom occurrences in Indian waters from 1908 to 2009 points out that a total of 101 cases have been reported. A comparison of the bloom ... -
Alkaline phosphatase activity at the southwest coast of India: A comparison of locations differently affected by upwelling..
(Elsevier, 2015)The realization of the potential importance of phosphorus (P) as a limiting nutrient in marine ecosystem is increasing globally. Hence, the contribution of biotic variables in mobilizing this nutrient would be relevant ... -
Alongshore wind stress and heat flux divergence off Visakhapatnam, east coast of India
(CSIR-NISCAIR, 1994)Annual variation of heat flux divergence (Qv) was computed for the coastal waters of Visakhapatnam. The mean values of net heat exchange (Qn) and heat flux divergence (Qv) were found to be 114 and 115 W.m/2 respectively ... -
Altimetric observations and model simulations of coastal Kelvin waves in the Bay of Bengal
(Taylor & Francis, 2012)Wavelet analyses of sea surface height (SSH) obtained from Simple Ocean Data Assimilation (SODA) reanalysis, satellite altimetry derived SSH anomalies during 1993–2006, and HYbrid Coordinate Ocean Model (HYCOM) simulations ... -
An overview of the planktonic foraminiferal fauna in waters off the Kerala Coast, south-west India during summer
(Marine Biological Association of India, 1997)Twentyeight species of planktonic Foraminifera are recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala Coast. The mean abundance of total foraminiferal sepcimens of all the stations ... -
Application of hybrid techniques (self-organizing map and fuzzy algorithm) using backscatter data for segmentation and fine-scale roughness characterization of seepage-related seafloor along the western continental margin of India
(IEEE, 2015)In this paper, a seafloor characterization technique to unravel the number of data classes using multibeam echo-sounding backscatter data has been demonstrated. An application of self-organizing maps (SOMs) to backscatter ... -
Arabian Sea oceanography and fisheries
(Fishery Survey of India, 2004)The physical and chemical forcing which drive the Arabian production is now fairly well understood. The main attributes, which contribute to the productivity are (1) the boundary processes which manifest as upwelling during ... -
Arabian Sea upwelling - A comparison between coastal and open ocean regions
(Current Science Association, Bangalore, India, 1996)The response of the eastern Arabian Sea to prevailing winds during an upwelling event, in the peak of southwest monsoon, was studied at both coastal and open ocean environment based on the data collected as a part of the ... -
Atypical delta sup(13) C signature in Globigerina bulloides at the ODP site 723A (Arabian Sea): Implications of environmental changes caused by upwelling
(Elsevier, 2004)Production of Globigerina bulloides generally increases during upwelling in the tropical ocean and, in particular, during southwest monsoon season in the Arabian Sea. We studied the delta sup(13) C signatures of Globigerina ... -
Carbon and oxygen isotope time series records of planktonic and benthic foraminifera from the Arabian Sea: Implications on upwelling processes
(Elsevier, 2003)Oxygen and carbon isotopic analyses have been performed on the tests of Globigerina bulloides and Pulleniatina obliquiloculata (planktonic foraminifera) and Uvigerina excellens (benthic foraminifer) to study the evolution ... -
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 oceanography of the Indian Ocean, North of the equator
(Elsevier, 1984)Chemical oceanographic studies in the North Indian Ocean have revealed several interesting and unique features. Dissolved oxygen northern boundary, prevents quick renewal of subsurface reducing conditions prevail at ... -
Coupling between SW monsoon-related surface and deep ocean processes as discerned from continuous particle flux measurements and correlated satellite data
(American Geophysical Union, 1996)Particle flux data obtained by time series sediment traps deployed at water depths of approximately 3000 m in the western, central, and eastern Arabian Sea since 1986 were compared with wind speeds derived from measurements ... -
Deep ocean fluxes and their link to surface ocean processes and the biological pump
(Elsevier, 2005)Intense studies of upper and deep ocean processes were carried out in the Northwestern Indian Ocean (Arabian Sea) within the framework of JGOFS and related projects in order to improve our understanding of the marine carbon ... -
Depth anomalies in the Arabian Basin, NW Indian Ocean
(Springer, 2008)Unreported depth anomalies in the Arabian Basin, northwest Indian Ocean is presented previously, to provide constraints on the evolution of the oceanic lithosphere of that basin. The depth anomaly reported in this study ... -
Distribution of nutrients in the shelf waters of the Arabian sea along the west coast of India
(National Institute of Sciences of India, 1968)The paper presents a descriptive account of the distribution of phosphates, silicates and nitrates in the shelf waters of Arabian Sea along the West Coast of India including a brief mention about the hydrographical features ... -
