(National Academy of Sciences, India, 1968)Euthecosomata (holoplanktonic opisthobranch molluscs) sorted out from the collections of the International Indian Ocean Expedition are now being studied and the present communication is a first report based on an examination ... -
A study of medusae from Andaman and Nicobar waters
(Zoological Society of Kerala, 1993)The results obtained from 14 cruises undertaken by FORV Sagar Sampada during the period 1986-1990 from Andaman and Nicobar waters are detailed. 346 zooplankton collections were made during this period and medusae were found ... -
A study on the zooplankton of the Burhabalanga Estuary, Orissa Coast
(Indian National Science Academy, 1996)Annual variations in the zooplankton biomass and composition during 1991-92 were studied from the inshore, mouth and upstream regions of the Burhabalanga Estuary located in the Orissa Coast (India). Zooplankton biomass was ... -
Abundance and community structure of chaetognaths in the northern Indian Ocean
(The Plankton Society of Japan, 2002)Abundance and community structure of chaetognaths in the northern Indian Ocean was investigated based on zooplankton samples collected during January to February 1990. Three types of sampling were done: from the upper ... -
An overview of dinoflagellate cysts in recent sediments along the west coast of India
(NISCAIR (CSIR), 2011)Distribution and abundance of dinoflagellate cysts in recent sediments along the west coast of India (26 coastal stations and 3 ports) is presented. A total of 47 different types of cysts and a maximum abundance of 1076 ... -
An overview of the planktonic foraminiferal fauna in waters off the Kerala Coast, south-west India during summer
(Marine Biological Association of India, 1997)Twentyeight species of planktonic Foraminifera are recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala Coast. The mean abundance of total foraminiferal sepcimens of all the stations ... -
Annual Variations in Zooplankton from a Polluted Coastal Environment
(Indian Association for Limnology and Oceanography, 1980)Seasonal changes in the composition and distribution of zooplankton from the coastal waters of Trivandrum were studied. The study indicated that the effluent discharged from a nearby titanium dioxide factory did not affect ... -
Assessment of biological characteristics on coastal environment of Murud (Maharashtra) during the oil spill (17 May 1993)
(NISCAIR, CSIR, 1995)A rupture of a feeder riser pipeline resulted in spillage of crude oil estimated to be 3000-8000 tonnes in Bombay High Region on 17 May 1993. The treated spill broken down into several patches and drifted south and finally ... -
