Zooplankton Composition and Diversity in Western Bay of Bengal
(Cambridge University Press, 1981)The biomass of zooplankton ranged from 1-90 ml/100 m3 in the western Bay of Bengal from off Sri Lanka to south of Calcutta in June 1978. The coastal belt between Madras and Visakhapatnam where upwelling is known to occur ... -
Some Physical Aspects of the Surface Waters around the little Andaman Island
(CSIR-NISCAIR, 1981)Along with the thermal and haline characteristics of the waters during the peak northeast monsoon period (February),observations on stratifications, inversions, mixed layers, nature and depth of thermocline, wind-induced ... -
On Two New Species of Siriella (Mysidacea)
(Indian Association for Limnology and Oceanography, 1981)Descriptions of two new mysids, Siriella africana ap. nov. collected from Agulhas Bank and S. intermedia sp. nov. collected from Laccadives are given. The present paper contains observations on two species of mysidacea ... -
Anisomysis Laccadivei, A new Mysid from Laccadives
(Indian Association for Limnology and Oceanography, 1981)Full description of Anisomysis laccadivei sp. nov. from Laccadives is given. During a taxonomic study of the mysidacea of the Laccadives a new species belonging to the genus Anisomysis Hansen was collected and is described ... -
Studies on Mangrove Swamps of Goa 1. Heterotrophic Bacterial Flora from Mangrove Swamps
(Indian Association for Limnology and Oceanography, 1981)Heterotrophic bacterial flora from the mangrove swamps of Goa consisted of physiologically active organisms exhibiting cellulolytic, pectinolytic, amylolytic, proteolytic and H2S forming activities, throughout the year. ... -
Studies on the Sediments of Vembanad Lake, Kerala State. 4. Distribution of Trace Elements
(CSIR-NISCAIR, 1981)Distribution patterns of FE, Mn, Ti, Ni, Co and Cu in sediments of Vembanad Lake and adjoining river systems have revealed that (1) elemental concentrations follow closely the texture of the sediments, (2) river sands ... -
Zooplankton Abundance of the Andaman Sea
(CSIR-NISCAIR, 1981)Zooplankton biomass and abundance of major groups from the Andaman Sea in February 1979 are presented. Average zooplankton biomass is 5.6 ml/100 m3 and is generally poor compared to reported values from east and west coasts ... -
Behaviour of Boron, Calcium and Magnesium in Mindola River Estuary (Gujarat)
(CSIR-NISCAIR, 1981)Ratios of B:Cl, Ca:Cl and Mg:Cl were generally within limit of river water at one end and seawater at the other. Percentage addition or removal (PA & PR) of B, Ca and Mg was calculated using the concept of the theoretical ... -
Distribution of Chaetognaths in the Polluted and Unpolluted Waters around Bombay
(CSIR-NISCAIR, 1981)Chaetognath fauna inhabiting the nearshore waters of Bombay was studied during Oct. 1977- Sept.1978. Among the 4 stations investigated Thana and Mahim represent polluted regions while Harbour and Versova are relatively ... -
Biomass and Composition of Zooplankton in Auranga, Ambika, Purna and Mindola Estuaries of South Gujarat
(CSIR-NISCAIR, 1981)Biomass and composition of zooplankton in the nearshore waters of Thal, Maharashtra, India were studied at 9 stations during Feb. 1980 to Jan. 1981. The recorded variation in zooplankton biomass was 4.8-80.6 ml.(100 m ... -
Boron-Chlorinity Relationship in Western Bay of Bengal
(CSIR-NISCAIR, 1981)Significant scatter in B/Cl beyond the limit of experimental error indicates that the ratio is not truly constant. B/Cl maximum, centred around 100 m, appears to be influenced by colloidal and particulate matter while the ... -
