Calanoid copepods of the International Indian Ocean Expedition
(Oxford and IBH, New Delhi, 1992)The distribution of calanoid copepods is discussed based on the subsorted taxa of the International Indian Ocean Expedition samples. Of the 32 calanoid taxa only 17 groups were considered as significant components. The ... -
Lunar, diel and tidal variabilityin penaeid prawn larval abundance in the Mandovi estuary, Goa
(NISCAIR, New Delhi, 1992)Prawn larvae were studied to determine suitable lunar and tidal phases and time for large scale seed collection for prawn aquaculture. Larvae and postlarvae of 8 commercially important species were observed in the surface ... -
Resource potential and status of pearl oyster fishery in India
(Society for Marine Archaeology, Goa, 1992)Many cultivable species of pearl oysters are known to occur in the Indo-Australian Archipelago which is an important region in the world distribution of pearl oysters. An account of the development of Indian pearl fisheries ... -
Zooplankton standing stock assessment and fishery resources in the indian seas
(Oxford and IBH, New Delhi, 1992)Based on data from 1864 samples collected over a period of 12 years (1976-88), an assessment of zooplankton standing stock (biomass), secondary production and potential fishery resources has been made. The areas studied ... -
Differential sensitivity of pigmented and non-pigmented marine bacteria to metals and antibiotics
(Pergamon, 1992)The response of pigmented and non-pigmented marine bacteria to metals and antibiotics was investigated. The two groups responded differently to heavy metals and antibiotics. Pigmented bacteria were more resistant to metals. ... -
Tropical marine ecosystems: The microbial component
(Wiley Eastern, New Delhi, 1992)Microbes such as bacteria, fungi and unicellular algae assume greater importance in the tropical marine ecosystems because of their abundance, biomass and activity in a number of chemical and biological processes that ... -
Deep sea benthos of the western and central Indian Ocean
(Oxford and IBH, New Delhi, 1992)Quantitative investigations on deep sea benthos from 112 stations between lat. 21 degrees N-21 degrees S and long. 51 degrees E-94 degrees E and in the depth range of 1500 to 6000 m, revealed a rich biota having relatively ... -
Satellite and ship studies of phytoplankton along the west coast of India
(Oxford and IBH, New Delhi, 1992)AidEd. by a sequence of chlorophyll images from the Coastal Zone Color Scanner on board the Nimbus-7 satellite and extensive shipboard observations, a descriptive analysis of the factors influencing the distribution and ... -
Antifouling property of the fruits of Randia brandisii (Rubiaceae) and Sapindus trifoliatus (Sapindaceae)
(NISCAIR, New Delhi, 1992)Methanol extracts of fruits of Randia brandisii (Gamble) and Sapindus trifoliatus (Vah) were assessed for marine antifouling properties. The coatings of these crude extracts on aluminium coupons were found to inhibit ... -
Trophic dynamics and fishery potentials of the Indian Occean - critical assessment
(Oxford and IBH, New Delhi, 1992)A critical review of the status of the Indian Ocean marine fisheries reveals that the presently exploited annual catch is less than one third of the projected potentials as estimated from the biological productivity and ... -
Copepod composition along southwest and southeast coasts of India
(Oxford and IBH, New Delhi, 1992)Two sets of samples, one from upper layer of thermocline to surface and second set from 500 m to surface were made. Copepod fauna from these collections were studied in relation to the hydrographical properties of the water ... -
Circulation and geostrophic transport in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)Utilising the hydrographic data collected during the early northeast monsoon of 1983 and southwest monsoon of 1984, the circulation of waters of the Bay of Bengal and the associated volume transport have been studied in ... -
Equatorial jet - a case study
(NISCAIR, New Delhi, 1992)Detailed EOF analysis of wind data reportEd. by Wunsch over Gan (00 degrees 41'S; 73 degrees 10'E) is made for the period 1963-70. The year 1964, which exhibited least variability from mean wind structure, has been chosen ... -
Reduced order ARMA spectral estimation of ocean waves

Hydrography and circulation in the northwestern Bay of Bengal during the retreat of southwest monsoon
(Indian Academy of Sciences, 1992)The distribution of temperature and salinity in the upper 500 m of the northwestern Bay of Bengal, adjoining the East Coast of India, during the retreat of southwest monsoon (September) of 1983 is presented. This study ... -
A longshore sediment transport estimation for the Indian coast
(Indian Society for Physical Sciences of the Oceans, 1992)An empirical sediment transport model has been developed based on longshore energy flux equation. Study indicates that annual gross sediment transport rate is high (1.5 x 10 super(6) m super(3) to 2.0 x 10 super(6) m ... -
On the role of geometry of cross-section in generating flood-dominance in shallow estuaries
(Academic Press, 1992)Shallow estuaries often show tidal asymmetry of flood-dominance in which duration of the flood is shorter and its peak discharge larger than the corresponding values during ebb. A simple analytic model for this phenomenon ... -
A solution to the inverse problem in ocean acoustics
(DESIDOC, New Delhi, 1992)The methodology and software developed to reconstruct a vertical sound speed profile as a part of studies on the marine acoustic modelling, using the ray path lengths and the travel time perturbations in tomographic layers ... -
Multivariate autoregressive algorithms for ocean wave modelling
(International Society of Offshore and Polar Engineers, 1992) -
Ocean surface waves and winds over the north Indian Ocean from satellite altimeter - preliminary results of SAC-NIO joint project
(Indian Society for Physical Sciences of the Oceans, 1992)With the aim of retrieving, validating and mapping ocean surface winds and waves in the north Indian Ocean, GEOSAT altimeter data for the period November 1986 to October 1987 and available sea truth data for the above ...
