Uptake and bioconcentration of copper and zinc by the molluscs Saccostrea cucullata (Born) and Cerithium rubus (Desh) from the coastal waters of Bombay
(NISCAIR, New Delhi, 1992)Rate of uptake increased linearly during the initial period of 20-30 days. Compared to the gastropod, the rate of uptake in oyster was 2.2 and 9.4 times more respectively for Cu and Zn. In oysters collected from a polluted ... -
Uptake and loss of mercury, cadmium and lead in marine organisms
(NISCAIR, India, 1993)Experiments were conducted on Tilapia mosambica, Perna viridis and Villorita cyprinoides on the uptake and loss of Hg, Cd and Pb in various tissues of these organisms. Hg was found to be highly toxic to the clams as compared ... -

Upwelling along the east coast of India
(National Institute of Sciences of India, 1968)An examination of the physical characteristics of the shelf waters off Karaikal in the premonsoon period and off Madras and Waltair in the premonsoon and monsoon periods reveals the presence of upwelling along the East ... -
Upwelling along the western Indian continental margin and its geological record - a summary
(New York: Plenum, 1983)Upwelling along the western Indian continental margin is recorded each year from Cape Comorin to Cochin and further north up to Goa from June to September during the southwest monsoon. During this upwelling heavy phytoplankton ... -
Upwelling and associated hydrography along the west coast of india during southwest monsoon, 1999
(NIO, Dona Paula, Goa (India), 2000)During May 1999 twenty-five hydrographic stations were carried out covering the waters of the west coast of India from 8 degrees N to 13 degrees N as a part of Marine Research - Living Resources (MR-LR) programme. The ... -
Upwelling and sinking along Visakhapatnam coast
(CSIR-NISCAIR, 1986)Stability and stratification of the water over the shelf disappear as cold saline waters characteristic of 60 m depth rise to the surface during March. Tilting of isopycnals and offshore displacement of isohalines suggest ... -
Upwelling features near Sri Lanka in the Bay of Bengal
(Andhra University, 2005)The Bay of Bengal is a semi-enclosed tropical ocean basin that is highly influenced by monsoons and receives large volume of freshwater from both river discharge and rainfall. Over the Bay of Bengal two distinct wind systems ... -

Upwelling induced changes in the abundance and community structure of archaea and bacteria in a recurring mud bank along the southwest coast of India
(Elsevier, 2018)The present study reports the influence of upwelling on the abundance and community structure of archaea and bacteria in a mud bank formed along the coastal waters of Alappuzha, the southwest coast of India. The signatures ... -
Upwelling intensity modulates N2O concentrations over the western Indian shelf
(American Geophysical Union Publications, 2016)Repeat measurements of dissolved nitrous oxide (N<sub>2</sub>O) along two transects of the western continental shelf of India in 2012 revealed high concentrations of 45±32 nM (off Kochi) and 73±63 nM (off Mangalore) during ... -

Uranium series disequilibrium in the coastal surface sediments and sea water of the Arabian sea
(Elsevier, 1988)Nearshore surface sediments from various locations of the West Coast of India were leached by saturated ammonium carbonate solution for the extraction of uranium isotopes. The reagent chosen was found to have high efficiency ... -

Urea as nitrogen source for phytoplankton production in coastal waters of Goa
(CSIR-NISCAIR, 1985)Annual variation of urea in coastal waters off Goa, India is 0 to 2.92 mu g-at N.1/1 and 0 to 4.69 mu g-at N.1/1 in adjacent estuarine waters of Mandovi. Peaks of phytoplankton production accompanied with the decrease in ... -
Use of a chiA probe for detection of chitinase genes in bacteria from the Chesapeake Bay
(FEMS, 2000)PCR primers specific for the chiA gene were designed by alignment and selection of highly conserved regions of chiA sequences from Serratia marcescens, Alteromonas sp., Bacillus circulans and Aeromonas caviae. These primers ... -

Use of chemicals in aquaculture - issues of concern
(Indian Society for Fishery Professionals, 1999)Majority of aquaculture practices are still based on extensive and semi-intensive farming systems though a trend to intensify operations to enhance yields and improve the efficiency of the production process has emerged ...
