Currents and Siltation at Dharamtar Creek, Bombay
(Indian Association for Limnology and Oceanography, 1980)Hydrographic data collected in Dharamtar Creek during 1976-77 have been analysed. This showed that the waters in the Creek are well mixed and the salinity varied with the tide. The tidal currents are found to be generally ... -
Delta sup(14)C, sigma CO sub(2) salinity of the western Indian Ocean deep waters: Spatial and temporal variations
(American Geophysical Union, 1999)Indian Ocean Deep waters (IDW) show an increase in salinity and sigma CO sub(2) between 64 degrees S and 16 plus or minus 4 degrees N by 0.106-0.110 ppt and 82-104 mu M kg sup(-1) respectively with a corresponding decrease ... -
Distribution of nutrients in the coastal and estuarine waters of Goa
(Indian Association for Limnology and Oceanography, 1987)Concentrations of nitrate and phosphate in the coastal waters of Goa varied from 0 to 2.4 mu g at 1-1 and from 0.1 to 2.4 mu g at 1-1 respectively, during post and premonsoon periods. In the estuarine region the nutrients ... -
Distribution of phytoplankton along an environmental gradient off Kakinada, East Coast of India.
(NISCAIR, 2014)In the present study phytoplankton distribution and species composition was examined on a salinity gradient from River (R), River Mouth (RM) and coastal water (RF) at surface and subsurface layers along the coast off ... -
Diurnal variation of zooplankton off Versova (Bombay)
(Indian Association for Limnology and Oceanography, 1984)Physicochemical parameters and diurnal variaion of zooplankton were studied off Versova on 17/18 February 1981. Salinity and dissolved oxygen showed limited variation during the period of study. Nutrient values followed ... -
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 ... -
Do cold, low salinity waters pass through the Indo-Sri Lanka Channel during winter?
(Taylor & 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 ... -
Does subterranean flow initiate mud banks off the southwest coast of India?
(Elsevier, 2004)Coastal waters off the southwest coast of India draw special attention because of the occurrence of mud banks at certain locations during southwest monsoon period. The present study puts forward a hypothesis of a subterranean ... -
Drift in salinity data from Argo profiling floats in the Sea of Japan
(American Meteorological Society, 2012)In drift analysis of salinity sensors, one major problem is the difficulty in delineating sensor drift from water mass changes. In the present study, a new method is proposed for finding sensor drift that is free from water ... -
Ecological observations of major Salicornia beds from highly saline coastal wetlands of India
(Society of Wetland Scientists, 2002)Extensive Salicornia beds along the Gulf of Kutchchh (northwest) and Tamilnadu (southeast) coasts were investigated with respect to vegetative structure and ambient environmental conditions. The width of the beds varied ... -
Ecological Studies on the Seasonal Production of the Edible Oyster, Crassostrea Madrasensis (Preston) in Cochin Backwater, Kerala
(Indian Association for Limnology and Oceanography, 1981)Seasonal variation in the standing crop of intertidal oyster Crassostrea madrasensis at Ramanthuruth and Vallarpadom in the Cochin backwater for the period July 1974 to December 1975 showed that the maximum yield (whole ... -
Ecology of Pleuromamma indica Wolfenden (Copepoda - Calanoida) in the Indian Ocean
(CSIR-NISCAIR, 1986)Pleuromamma indica was the only species among the 7 species of the genus, recorded in the area, to be present in 2 restricted areas, one near the mouth of the Gulf of Oman in the Arabian Sea and the other in the Bay of ... -
Ecology of the wood-boring bivalve Martesia striata (Pholadidae) in Indian waters
(Academic Press, 1999)Martesia striata is one of the dominant wood-boring organisms found in Indian waters. Incidence of this organism in the Zuari estuary (Goa) was evaluated by exposing wooden panels (Mangifera indica) to the marine environment ... -
Effect of environment on pigment ratios in Dunaliella spp. from the salt pans of Gujarat
(Indian Academy of Sciences, Bangalore, 1989)The effect of varying salinity and pH of the medium on growth and pigment ratios of Dunaliella cells in culture was studied. Cell growth was found to be optimal at pH 8 and at intermediate salt concentrations of 1-2 M NaCl. ... -
Effect of eyestalk extirpation on haemolymph ionic concentration of Metapenaeus monoceros
(Horizon Publisher, 2013)Metapenaeus monoceros in the size range 65-70mm was subjected to the evaluation of sodium(Na<sup>+</sup>),, potassium (K<sup>+</sup>) and calcium (Ca<sup>2+</sup>) ionic concentration in the haemolymph after unilateral ... -
Effect of salinity induced pH/alkalinity changes on benthic foraminifera: A laboratory culture experiment
(Elsevier, 2015)The salinity of coastal waters in the vicinity of seasonally fresh water fed estuaries changes tremendously and reportedly affects the living calcite secreting organisms like foraminifera, as well as their dead remains. ... -
Effect of temperature, salinity and biofilm on the zoospores settlement of Enteromorpha flexuosa (Wulfen) J.Agardh
(CSIR-NISCAIR, 2012)The effect of temperature (10-30 degrees C), salinity (15-35 psu) and biofilm on the settlement of Enteromorpha flexousa zoospores was assessed. Settlement of zoospores was significantly (p less than 0.05) influenced by ... -
