Characterizing Indian Ocean manganese nodule-bearing seafloor using multi-beam angular backscatter
(Springer, 2004)Application of quantitative angular backscatter modelling to manganese nodule-bearing areas of the Central Indian Ocean Basin (CIOB) has been initiated at NIO during the year 1998. Studies were aimed to establish the ... -
Cladocera in the Estuarine and Coastal Waters of South-West Coast of India
(Indian Association for Limnology and Oceanography, 1981)Occurrence and abundance of marine Cladocera in several estuaries along the south-west coast of India is presented and compared with their distribution in the coastal waters. One peculiar feature observed was their absence ... -
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 ... -

Decapod Larvae from the Nearshore Waters of Karwar
(Indian Association for Limnology and Oceanography, 1980)Abundance of decapod larvae at three stations in Binge Bay, Karwar has been reported based on surface collections taken during the period October 1975 to September 1976. The larvae were very common in the Bay and the ... -
Determination of nodule coverage parameters using multibeam normal incidence echo characteristics: A study in the Indian Ocean
(Taylor and Francis, 1997)A study of the echo peak amplitudes from known nodule areas is initiated to observe the acoustic response for varying nodule abundances and number densities. A statistical study of the peak amplitudes from different nodule ... -
Diatoms of the microphytobenthic community in a tropical intertidal sand flat influenced by monsoons: Spatial and temporal variations
(Springer, 2006)Seasonal variations in the microphytobenthic diatom community were investigated in an intertidal sand flat of a tropical marine environment influenced by monsoons. Cores of sediments were collected along the beach gradient: ... -
Diatoms of the microphytobenthic community: Population structure in a tropical intertidal sand flat
(Springer, 2002)Temporal and spatial variations were investigated in the viable diatom population of the microphytobenthic community from an intertidal sand flat of a tropical environment. The presence of diatoms to a sediment depth of ... -
Distribution and abundance of copepods in the pollution gradient zones of Bombay Harbour-Thana Creek-Bassein Creek, west coast of India
