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 ... -
Dissolved oxygen - A target indicator in determining use of the Gulf of Kachchh waters
(Elsevier, 2005)Spatial and temporal variations of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) in the Gulf of Kachchh (GoK), India are assessed based on data collected since 1976.DO concentrations in the interior GoK vary ... -
Do cold, low salinity waters pass through the Indo-Sri Lanka Channel during winter?
(Taylor and Francis, 2011)During winter, along the east coast of India, the near-surface flow is characterized by the southward-flowing East India Coastal Current (EICC) which bends around Sri Lanka and enters into the south-eastern Arabian Sea ... -

Evidences of climatic variations during Late Pleistocene- Holocene in the eastern Bay of Bengal
(Current Science Association, Bangalore, India, 1993)Based upon the variations of clay minerals, sediment texture, heavy mineral assemblage and sup(230)Th excess in the Late Pleistocene sediments of a hemipelagic core from the eastern Bay of Bengal (2713 m water depth), 35 ... -
Factors controlling the temporal and spatial variations in Synechococcus abundance in a monsoonal estuary
(Elsevier, 2013)Temporal and spatial variations in Synechococcus abundance were investigated over an annual cycle (February`10–January`11) along a salinity gradient (0–35) in the tropical Zuari estuary, influenced by south-west monsoons. ... -
Fluctuating monsoonal precipitation as revealed by foraminiferal variations in a core from shelf regime off Karwar (India)
(Current Science Association, 1988)Variations in the percentage frequency of the foraminifera Cavarotalia annectens in the sediments collected by box core in the shelf region of Karwar, infront of the mouth of the Kalinadi river, India were used to map ... -
Intraseasonal vertical velocity variation caused by the equatorial wave in the central equatorial Indian Ocean
(American Geophysical Union, 2011)Intraseasonal vertical velocity variation in the central equatorial Indian Ocean was investigated using observations from the field experiment "Mirai Indian Ocean Cruise for the Study of the MJO-convection Onset" and from ... -
Major and trace element geochemistry of Bay of Bengal sediments: Implications to provenances and their controlling factors
(Elsevier, 2014)Major and trace elements of sediments from a ~ 13-m long piston core (SK187/PC33) from the western Bay of Bengal have been investigated in this study to infer about the changes in provenances and related controlling factors ... -
Microbiological Studies in the Mandovi-Zuari River System
(CSIR-NISCAIR, 1981)Total heterotrophic and coliform bacteria were surveyed during October 1977 to September 1978 from 9 stations each along the rivers Mandovi and Zuari and 3 along the coast of Goa. Total heterotrophic population showed wide ... -
Non-conservative controls on distribution of dissolved silicate in Cochin Backwaters
(Asian Fisheries Society, Indian Branch, Mangalore (India), 1999)Cochin backwater system was studied with regard to dissolved silicate (DSi) to understand its seasonal distribution and behaviour during estuarine mixing. Silicate had a linear relationship with salinity during the high ... -
Numerical simulations of barnacle larval dispersion coupled with field observations on larval abundance, settlement and recruitment in a tropical monsoon influenced coastal marine environment
(Elsevier, 2012)Observations were carried out to monitor the larval abundance, settlement and recruitment of barnacles on a regular basis for a period of two years. The results were then compared with the numerical modelling studies carried ... -
Oceanography of Wadge bank - current measurements over a tidal cycle off the south coast of India
(CSIR-NISCAIR, 1986)Direct current measurements made during the onset and termination of SW monsoon indicate wide fluctuations in space and time. The nearshore current decreases in magnitude from the onset to the termination of the monsoon. ... -
Orbital frequencies in radiolarian assemblages of the central Indian Ocean: implications on the Indian summer monsoon
(Elsevier, 2003)Radiolarian distribution in surface sediments and its relationships with overlying surface oceanography provided impetus for down-core faunal variation related to changes in monsoon intensity due to the Earth's orbital ... -
Particulate carbohydrates in the Arabian Sea
(Elsevier, 1989)Particulate carbohydrate (PECHO) was measured for 183 samples collected from 8 depths at 23 stations. The (PCHO) concentrations varied from 22 to 125 mu g.l-1 (x bar = 52.42 plus or minus 19.56 mu g.l-1 at the surface and ... -
Phytoplankton pigments and macrobenthos in nearshore waters off an oil terminal at Uran (Maharashtra), west coast of India
(NISCAIR, CSIR, 1998)Significant temporal and tidal variations of chlorophyll a (2.11-11.8 mg m sup(-3)) were noticed. Chlorophyll a was less during low tide (av. 3.8 mg m sup(-3)) as compared to high tide (av. 8.1 mg m sup(-3)). The predominance ... -
