Primary productivity in Mandovi-Zuari estuaries in Goa
(Marine Biological Association of India, 2002)Measurement on primary production, phytoplankton biomass, POC and PON were made for a period of ten months at a coastal station and for fourteen months at two estuarine stations in Goa (west coast of India). Irrespective ... -
Frequency distribution of Foraminifera in the Chilka lake
(Marine Biological Association of India, 2001)A total of sixtynine foraminiferal species have been identified from the sediment samples collected from the Chilka Lake during November 1997 and March, May 1998. These species have been quantitatively studied in regard ... -
UV radiation and natural fluorescence linked primary production in Antarctic waters
(Marine Biological Association of India, 2001)Primary productivity and chlorophyll values have been measured using an underwater profiling radiometer for the first time in the waters around Indian Antarctic Station (70°46'S & 11°44'E) in the summer of 1994. The profiles ... -
Seasonal cycle of hydrography in the Bab el Mandab region, southern Red Sea
(Indian Academy of Sciences, 2004)The seasonal cycle of temperature - salinity variations in the Bab el Mandab region (southern Red Sea) is described using CTD data collected during four cruises spread over the period May 1995 { August 1997. A two layer ... -
Late Quaternary sea level and environmental changes from relic carbonate deposits of the western margin of India
(Indian Academy of Sciences, 2003)Relic carbonate deposits along the western margin of India occur as dolomite crusts, aragonite sands (pelletal / oolitic) and aragonite-cemented limestones, oyster shells, corals, encrusted coralline algal and foraminife ... -
Retrieval of sea surface velocities using sequential Ocean Colour Monitor (OCM) data
(Indian Academy of Sciences, 2002)The Indian remote sensing satellite, IRS-P4 (Oceansat-I) launched on May 26th, 1999 carried two sensors on board, i.e., the Ocean Colour Monitor (OCM) and the Multi-frequency Scanning Microwave Radiometer (MSMR) dedicated ... -
Chlorophyll modulation of mixed layer thermodynamics in a mixed-layer isopycnal General Circulation Model - An example from Arabian Sea and equatorial Pacific
(Indian Academy of Sciences, 2002)Western tropical Indian Ocean, Arabian Sea, and the equatorial Pacific are known as regions of intense bio-chemical-physical interactions: the Arabian Sea has the largest phytoplankton bloom with seasonal signal, while the ... -

Formation of diapiric structure in the deformation zone, central Indian Ocean: A model from gravity and seismic reflection data
(Indian Academy of Sciences, 2002)Analyses of bathymetry, gravity and seismic reflection data of the diffusive plate boundary in the central Indian Ocean reveal a new kind of deformed structure besides the well-reported structures of long-wavelength ... -
Seasonal controls on surface pCO2 in the central and eastern Arabian Sea
(Indian Academy of Sciences, 2000)The variability in partial pressure of carbon dioxide (pCO2) and its control by biological and physical processes in the mixed layer (ML) of the central and eastern Arabian Sea during inter-monsoon, northeast monsoon, and ... -
Abundance and relationship of bacteria with transparent exopolymer particles during the 1996 summer monsoon in the Arabian Sea
(Indian Academy of Sciences, 2000)Bacterial abundance and production, numbers, sizes and concentrations of transparent exopolymer particles (TEP) and total organic carbon (TOC) were measured during the 1996 summer monsoon to understand the relationship ... -
Physical control of primary productivity on a seasonal scale in central and eastern Arabian Sea
(Indian Academy of Sciences, 2000)Using in situ data collected during 1992-1997, under the Indian programme of Joint Global Ocean Flux Study (JGOFS), it is shown that the biological productivity of the Arabian Sea is tightly coupled to the physical forcing ... -
Controls of dimethyl sulphide in the Bay of Bengal during BOBMEX-Pilot cruise 1998
(Indian Academy of Sciences, 2000)The air-sea exchange is one of the main mechanisms maintaining the abundances of trace gases in the atmosphere. Some of these, such as carbon dioxide and dimethyl sulphide (DMS), will have a bearing on the atmospheric heat ... -
Diurnal variability of upper ocean temperature and heat budget in the southern Bay of Bengal during October-November, 1998 (BOBMEX-Pilot)
(Indian Academy of Sciences, 2000)Time-series data on upper-ocean temperature, Vessel-Mounted Acoustic Doppler Current Profiler (VM-ADCP) measured currents and surface meteorological parameters have been obtained for the first time in the southern Bay of ... -
Thermohaline structure and circulation in the upper layers of the southern Bay of Bengal during BOBMEX-Pilot (October-November 1998)
(Indian Academy of Sciences, 2000)Hydrographic data collected on board ORV Sagar Kanya in the southern Bay of Bengal during the BOBMEX-Pilot programme (October -- November 1998) have been used to describe the thermohaline structure and circulation in the ... -
Glacial-interglacial changes in the surface water characteristics of the Andaman Sea: Evidence from stable isotopic ratios of planktonic foraminifera
(Indian Academy of Sciences, 2000)Stable carbon and oxygen isotopic analyses of the planktonic foraminifera (Globigerinoides ruber) from a deep sea sediment core (GC-1) in the Andaman Sea show high glacial-to-Holocene d<sup>18</sup>O amplitude of 2.1% which ... -
Observations of trace gases and aerosols over the Indian Ocean during the monsoon transition period
(Indian Academy of Sciences, 2006)Characteristics of trace gases (O sub(3), CO, CO sub(2), CH sub(4) and N sub(2)O) and aerosols (particle size of 2.5 micron) were studied over the Arabian Sea, equatorial Indian Ocean and southwest part of the Bay of Bengal ... -
