Seasonal distribution of chlorophyll-a in the Exclusive Economic Zone (EEZ) of India
(NISCAIR, CSIR, 1998)measonal distribution of chlorophyll-a (chl-a)) in the different sectors of the EEZ of India was studied based on data from 430 stations over the period from 1962 to 1988. The annual average chl-a for the entire euphotic ... -
Brackishwater shrimp farming: Possible impacts on estuarine ecosystem
(University of Kerala, Kerala (India), 1998)Aquaculture has been widely accepted as a practice that will supplement the capture fishery production, besides generating various types of job opportunities for the rural population. Coastal aquaculture has been given ... -
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 ... -
Zooplankton variability and copepod assemblage in the coastal and estuarine waters of Goa along the central-west coast of India
(Intergovernmental Oceanographic Commission, 1998)Seasonal variations in zooplankton distribution and community structure of copepod species in coastal and estuarine waters of Goa along the central-west coast of India are compared in relation to water temperature, salinity ... -
Community structure of meiobenthos from a tropical estuary
(NISCAIR, CSIR, 1998)Meiofaunal samples were collected from 3 stations, located in the salinity gradient of Zuari Estuary of Goa. Spatially the abundance of meiofauna decreased from lower to upper reaches and followed the trend of salinity ... -
Sustainable shrimp farming in India - Prospects and challenges
(CUSAT, Cochin (India), 1998)Shrimp farming has grown into a multi-crore industry in India. It has vast potential for further expansion. However, this growing industry needs to develop appropriate indigenous technologies in specific areas to make it ... -
Vertical distribution of mesozooplankton in the central and eastern Arabian Sea during the winter monsoons
(Cambridge University Press, 1998)The vertical distribution of mesozooplankton in the central and eastern Arabian Sea was investigated during the winter monsoon in 1995. Samples were analysed from discrete depth zones defined according to oxygen and ... -
Computer aided taxonomy (CAT): Approach for understanding systematics of marine biota
(NISCAIR, CSIR, 1998)Computer aided taconomy (CAT) is gaining importance day by day. In order to familiarise the taxonomy and its continuing usage an attempt has made to develop a module for knowing the systematics of organisms and to generate ... -
Genetic variations in marine natural population - Measurement and utility in resource management and conservation: A review
(NISCAIR, CSIR, 1998)A number of molecular and biochemical tools which can be applied to the identification of species and the detection of genetic variation within species have been developed in recent years. All these methods rely on the ... -
Disease and stress-induced mortality of corals in Indian reefs and observations on bleaching of corals in the Andamans
(Current Science Association, Bangalore, India, 1999)A study was carried out in the Lakshadweep and Andaman islands and the Gulf of Kutch to assess the health of corals in Indian reefs. Disease, predation and stress were the major factors of coral mortality. Death caused by ... -
Seasonal variation of sea surface temperature in the Bay of Bengal during 1992 as derived from NOAA-AVHRR SST data
(Taylor and Francis, 1998)Monthly maps of sea surface temperature (SST) derived for NOAA (National Oceanic and Atmospheric Administration)-AVHRR (Advanced Very High Resolution Radiometer) data during 1992 for the Bay of Bengal are analysed and ... -
Barotropic tidal model for the Bombay High, Gulf of Khambhat and surrounding areas
(Naval Physical and Oceanographic Laboratory, Thrikkakara, Kochi, India, 1998)A barotropic model is developed for the shelf region off the central west coast of India, which includes the regions of Bombay High and Gulf of Khambhat, in order to simulate tides and tidal currents in the region. The ... -
Coastal circulation in the North Indian Ocean: Coastal segment (14,S-W)
(John Wiley and Sons, New York, USA, 1998)The article provides an overview of the circulation of the coastal regime of the North Indian Ocean stretching from southern coast of Indonesia to the coast of East Africa. A special feature of this regime is that it ... -
Seasonal and inter-annual sea surface height variations of the northern Indian Ocean from the TOPEX/POSEIDON altimeter
(NISCAIR, CSIR, 1998)The seasonal and inter-annual variability of the northern Indian Ocean was studied by analysing 10-day snapshots of sea surface height (SSH) data from TOPEX/POSEIDON altimeter for the period November 1992 to August 1995. ... -
Modelling of coastal current and thermal plume dispersion - A case study off Nagapattinam, east coast of India
(Naval Physical and Oceanographic Laboratory, Thrikkakara, Kochi, India, 1998)Thermal plume simulation has been carried out using a 2D model to understand the nature of spreading and rate of cooling of warm water discharge from a proposed outfall in the nearshore region off Nagapattinam, Tamil Nadu, ... -
Retrieval and processing of atmospheric parameters from satellite data
(Pergamon, 1998)Remote sensing of each of passive microwave channels enables one to estimate the atmospheric parameters over oceans on a repetitive basis throughout the year. Such a data base forms a useful tool in the study of complex ... -
Mixing and flushing time scales in the Azhikode Estuary, southwest coast of India
(NISCAIR, CSIR, 1998)Flushing time scales of the Azhikode Estuary, Kerala, India showed pronounced dry season and wet season signals as well as large inter-annual variation. Cumulative flushing time of the estuary varies from 4.8 tide cycles ... -
Moisture source for summer monsoon rainfall over India
(The Association of Hydrologists of India, 1998)Southwest monsoon plays a vital role in India's economy as the major income comes from agriculture. What could be the moisture source for this copious amount of rainfall over the Indian sub-continent?. This has been studied ... -
Detection of Bay of Bengal eddies from TOPEX and insitu observations
(Naval Physical and Oceanographic Laboratory, Thrikkakara, Kochi, India, 1998)Oceanic eddies are characterised by gradients in the sea surface height (SSH) and temperature both at the surface and the subsurface. However, since the Bay of Bengal waters are more stratified, the gradients in SST may ...
