Dynamics of thraustochytrid protists in the water column of the Arabian Sea
(Inter-Research, 2001)Thraustochytrids, a group of osmoheterotrophic chromistan protists are ubiquitous in the sea. However, little is known of their ecological role, particularly in oceanic waters. To obtain in insight into their dynamics in ... -
Enhanced export of carbon by salps during the northeast monsoon period in the northern Arabian Sea
(Elsevier, 2005)A drifting sediment trap was deployed and sup(234)Th activity in the water column was measured to calculate export flux of carbon at a time-series station in the northern Arabian Sea (lat. 21 degrees 30 minutes N; long. ... -
Hydrochemistry of the Bay of Bengal: Possible reasons for a different water-column cycling of carbon and nitrogen from the Arabian Sea
(Elsevier, 1994)A study on biogeochemical cycling in the western Bay of Bengal was undertaken during two seasons (pre-southwest monsoon and northeast monsoon of 1991). Relationships of the conservative tracers NO and PO with potential ... -
Hydrothermal plumes over the Carlsberg Ridge, Indian Ocean
(American Geophysical Union, 2012)Water column surveys and sampling in 2007 and 2009 was conducted to search for hydrothermal plumes over a segment of the Carlsberg Ridge. An evidence for two separate vent fields, one near 3 degrees 42′N, 63 degrees 40′E ... -
Impact of total organic carbon (in sediments) and dissolved organic carbon (in overlying water column) on Hg sequestration by coastal sediments from the central east coast of India
(Elsevier, 2014)Total organic carbon (TOC) (in sediment) and dissolved organic matter (DOM) (in water column) play important roles in controlling the mercury sequestration process by the sediments from the central east coast of India. ... -
Indian Deep-sea Environment Experiment (INDEX): An appraisal
(Pergamon, 2001)Indian Deep-sea Environment Experiment (INDEX) is a multi-disciplinary study to establish baseline conditions and evaluate the possible impact of deep-seabed mining in Central Indian Basin. A disturbance was simulated to ... -
M sub(2) tidal currents on the shelf off Goa, west coast of India
(Publ. and Inf. Dir., New Delhi, India, 1994)Current meter records collected during three different months from a site off Goa (15 degrees 08'N, 73 degrees 16'E) over the western continental shelf of India have been used to describe the M sub(2) tidal structure in a ... -
Monsoon related changes in sea surface productivity and water column denitrification in the Eastern Arabian Sea during the last glacial cycle
(Elsevier, 2005)Sea surface salinity reconstruction for the Holocene and the Last Glacial Maximum (LGM) suggests that the LGM-Eastern Arabian Sea was more saline (by approx.5 psu) than the Holocene due to weakened freshwater flux to the ... -
Morphology and physiology of the marine straminipilan fungi, the aplanochytrids isolated from the equatorial Indian Ocean
(NISCAIR, CSIR, 2006)While thraustochytrids, a group of unicellular marine straminipilan protists, have been found to be abundant in the water column, little is known of aplanochytrids. These constitute one of the 3 groups belonging to the ... -
Nitrogen cycling in the suboxic waters of the Arabian Sea
(Springer, 2006)Arabian Sea contains one of the world's three large oxygen deficient zones (ODZ). Within the ODZ oxygen concentration is vanishingly small between about 200 and 800 m depth and in this depth interval denitrifications is ... -
Observations of barrier layer formation in the Bay of Bengal during summer monsoon
(American Geophysical Union, 2002)Time series of temperature and salinity in the upper ocean, measured at 17 degrees 30'N, 89 degrees E in the northern Bay of Bengal, from 27 July to 6 August 1999 captured an event of upper layer freshening. Initially, the ... -
Particle-associated bacterial dynamics in a tropical tidal plain (Zuari estuary, India)
(Inter Research, 2003)The dynamics of particle-associated bacteria (PAB) in a tropical estuary, Zuari, in Goa on the west coast of India, was studied for a year from September 1997 to October 1998. Bacterial abundance, productivity and enzymatic ... -
Physical characteristics of the coastal waters between Navapur and Umbharat, West coast of India. Part 3. Stability and dispersion
(Indian Association for Limnology and Oceanography, 1982)Vertical profiles of currents of the coastal waters between Navapur and Umbharat were analysed. Dynamic stability as well as the diffusion capacity of the water columns were estimated from the vertical distribution of ... -
Physical characteristics of the Laccadive sea (Lakshadweep)
(CSIR-NISCAIR, 1979)Vertical profiles of currents of the coastal waters between Navapur and Umbharat were analysed. Dynamic stability as well as the diffusion capacity of the water columns were estimated from the vertical distribution of ... -
Physical characteristics of the waters and water masses off the west coast of India during late spring
(CSIR-NISCAIR, 1974)Vertical profiles of currents of the coastal waters between Navapur and Umbharat were analysed. Dynamic stability as well as the diffusion capacity of the water columns were estimated from the vertical distribution of ... -
Phytoplankton biomass and primary production in Delagoa Bight Mozambique: Application of remote sensing
(Elsevier, 2007)A non-linear model that uses satellite-derived chlorophyll to estimate water-column primary production was developed and tested using data from the Delagoa Bight, where the model results compared well with local estimates. ... -
