234Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, 1996)We have determined the particle scavenging rates, export fluxes of @u234@@Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
Acoustic characteristics of the water of the Bay of Bengal
(NISCAIR, New Delhi, 1993)Acoustic eigen rays (rays connecting the source and receiver) have been indentified and their turning depth, path length, travel time etc. evaluated. Acoustic intensity loss due to mean environmental conditions, vergence ... -
Aggregation of Euphausia sibogae during summer monsoon along the southwest coast of India
(Hindawi Publishing, 2011)The influence of environmental parameters on the spawning aggregation of Euphausia sibogae was investigated along the southwest coast of India during the peak phase of summer monsoon 2005. The prevailing ecological conditions ... -
Annual and seasonal mean buoyancy fluxes for the tropical Indian Ocean
(Current Science Association, Bangalore, 1997)INSAT-derived monthly mean precipitation, combined with estimates of evaporation from COADS, are used to prepare the annual mean and seasonal distributions of evaporation-precipitation (E-P)) and buoyancy fluxes for the ... -
Beach Morphological Variations over Micro-Time Scales
(CSIR-NISCAIR, 1980)Nature and magnitude of beach changes over short periods have been studied at Calangute and Miramar in relation to tide, ground water level and relevant oceanographic and meteorological factors. Alternating zones of accretion ... -
Beach processes between Mulgund and Shiroda, west coast of India
(CSIR-NISCAIR, 1994)Study on beach processes for an year shows seasonal changes without annual net erosion. The beaches are stable and regain the maximum profiles during February to April. Distribution of longshore current direction is not ... -
Benthic studies in Goa estuaries. I. Standing crop and faunal composition in relation to bottom salinity distribution characteristics in the estuary of Mandovi River
(CSIR-NISCAIR, 1974)Macrobenthos in Mandovi, Cumbarjua canal and Zuari estuaries, a physically interconnected tropical estuarine system which undergoes large seasonal changes in salinity distribution due to heavy monsoonal precipitation, is ... -
Benthic Studies in Goa Estuaries. Part 3. Annual Cycle of Macrofaunal Distribution, Production and Trophic Relations
(CSIR-NISCAIR, 1980)Macrobenthos in Mandovi, Cumbarjua canal and Zuari estuaries, a physically interconnected tropical estuarine system which undergoes large seasonal changes in salinity distribution due to heavy monsoonal precipitation, is ... -
Benthic studies in Goa estuaries: Biomass and faunal composition in the Zuari estuary
(CSIR-NISCAIR, 1975)Macrobenthos in Mandovi, Cumbarjua canal and Zuari estuaries, a physically interconnected tropical estuarine system which undergoes large seasonal changes in salinity distribution due to heavy monsoonal precipitation, is ... -
Biofilm diatom community structure: Influence of temporal and substratum variability
(Taylor and Francis, 2005)Diatoms, which are early autotrophic colonisers, are an important constituent of the biofouling community in the marine environment. The effects of substratum and temporal variations on the fouling diatom community structure ... -
Biological productivity and potential resources of the exclusive economic zone (EEZ) of India
(Fishery Survey of India, 2004)An assessment of the biological production and the potential fishery resources has been made based on the data collected over a period of 15 years (1976-1991). The entire Exclusive Economic Zone (EEZ), measuring 2.02 million ... -
Carbon and nitrogen isotopic composition of suspended particulate organic matter in Zuari Estuary, west coast of India
(Elsevier, 2015)The spatio-temporal variations of the δ13C and δ15N of suspended particulate organic matter (SPOM), along with ancillary chemical and hydrographic parameters, have been examined monthly for one year (October 2010 to September ... -
Change in the intensity of low-salinity water inflow from the Bay of Bengal into the Eastern Arabian Sea from the Last Glacial Maximum to the Holocene: Implications for monsoon variations
(Elsevier, 2014)A 100–400 km wide region of the coastal Eastern Arabian Sea (EAS), off the west-coast of India, is characterized by a low-salinity tongue formed by the inflow of low-salinity surface water from the Bay of Bengal (BoB). ... -
Characterization of Porteresia coarctata beds along the Goa coast, India
(Elsevier, 2006)Porteresia coarctata, forms an important constituent in the plant succession leading to formation of mangrove communities along the estuaries in India. Major beds along the Mandovi estuary of Goa were monitored for their ... -
Clay minerals as palaeomonsoon proxies: Evaluation and relevance to the late Quaternary records from SE Arabian Sea
(NCAOR, Goa, 2005)Palaeoclimatic studies are largely dependent on the quality of records and a prudent use of environmental proxy indicators. In this study, the factors affecting the detrital clay minerals in marine environment and their ... -
Comparison of tropical cyclogenesis indices on seasonal to interannual timescales
(Springer-Verlag, 2012)The performances of four cyclogenesis indices against observed tropical cyclone genesis on a global scale over the period 1979–2001 are evaluated. These indices are: the Genesis Potential Index; the Yearly Genesis Parameter; ... -
