Features at some significant estuaries of India
(Oxford and IBH, New Delhi, 2001)The river basins of India are classified into three groups on the basis of catchment areas: (1) above 20,000 km sup(2), (2) 2,000-20,000 km sup(2) and (3) less than 2,000 km sup(2). The total number of rivers under first ... -
Biology of corals and coral reefs
(Oxford and IBH, New Delhi, 2001)This chapter deals with biology of corals, coral reefs (in general) and coral reefs of the Indian Ocean. Biology of corals is lucidly dealt with, beginning from the clarification on hermatypic and ahermatypic forms. A ... -
Temporal and ephemeral variations in copepod community in the estuaries of Mandovi and Zuari - west coast of India
(Cambridge Univ. Press, UK, 2001)In the tidal-dominated coastal plain estuaries, the magnitude of temporal and ephemeral variations in the abundance of the calonoid copepod community was evaluated over two annual cycles by two-way ANOVA. The species by ... -
Microbial biomass and organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin
(Taylor and Francis, 2001)In order to assess the impact of deep-sea mining on the in situ benthic life, the microbial standing stock and concentration of organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin in the Indian ... -
Fungi in Porites lutea: Association with healthy and diseased corals
(Inter-Research, 2001)Healthy and diseased scleractinian corals have been reported to harbour fungi. However, the species of fungi occurring in them and their prevalence in terms of biomass have not been determined and their role in coral ... -
Seaweed resources
(Oxford and IBH, New Delhi, 2001)The chapter summarizes our present knowledge of the seaweed resources of the Indian Ocean region with regard to the phytogeographical distribution, composition, biomass, utilization, cultivation, conservation and management. ... -
Degradation of crude oil by marine cyanobacteria
(Springer, 2001)The marine cyanobacteria Oscillatoria salina Biswas, Plectonema terebrans Bornet et Flanhault and Aphanocapsa sp. degraded Bombay High crude oil when grown in artificial seawater nutrients as well as in plain natural ... -
Extracellular polymeric substances of the marine fouling diatom Amphora rostrata Wm. Sm.
(Taylor and Francis, 2001)Amphora rostrata was grown under continuous illumination at 27 degrees C in batch cultures using f/2 medium. Cell biomass (measured as chlorophyll a and cell counts) reached a maximum on day 7. Thereafter, cell biomass as ... -
Dynamics of thraustochytrid protists in the water column of the Arabian Sea
(Inter-Research, 2001)Thraustochytrids, a group of osmoheterotrophic chromistan protists are ubiquitous in the sea. However, little is known of their ecological role, particularly in oceanic waters. To obtain in insight into their dynamics in ... -
Benthos
(Oxford and IBH, New Delhi, 2001)Benthic organisms are sessile and sedentary in nature. True benthos can be divided into two groups - epifauna and infauna. They comprise major invertebrate phyla. Benthic organisms are separated into micro, meio, macro and ... -
Larval development and metamorphosis in Balanus amphitrite Darwin (Cirripedia; Thoracica): Significance of food concentration, temperature and nucleic acids
(Elsevier, 2001)The influence of food concentration (Chaetoceros calcitrans at 1 x 10 sup(5) and 2 x 10 sup(5) cells ml sup(-1)) and temperature (20 degrees C and 30 degrees C) on the nucleic acid content of the nauplii and the cyprids ... -
Distribution and sources of organic carbon, nitrogen and their isotopic signatures in sediments from the Ayeyarwady (Irrawaddy) continental shelf, northern Andaman Sea
(Elsevier, 2008)Total organic carbon (TOC), total nitrogen (TN) and their delta sup(13) C and delta sup (15) N values were determined from 110 sediment samples from the Ayeyarwady (Irrawaddy) continental shelf, northern Andaman Sea to ... -
Enrique Balech Capdeville (1912–2007)
(Current Science Association, 2008)Enrique Balech Capdeville, a ‘pioneer’ micro-algal taxonomist, was born on 17 August 1912 in a French family at Telen, La Pampa, Argentina. During his long scientific career, Balech studied almost all dinoflagellate genera. ... -
Reflections on the discovery of toxic species of marine micro-algae known to form harmful blooms
(Current Science Association, 2008)The communication reflects how the discoveries of toxic species vis-a- vis marine micro-algal taxonomy has been progressing. It also underlines the importance of both taxonomy of HAB ( harmful algal bloom) species and ... -
Estimating boundary currents from satellite altimetry: A case study for the east coast of India
(The Oceanographic Society of Japan, 2008)A methodology to derive surface geostrophic current from a newly released altimetric sea-level data set is presented. TOPEX/Poseidon data were first completely reprocessed from Geophysical Data Records using new algorithms ... -
Rock magnetic and geochemical record in a sediment core from the eastern Arabian Sea: Diagenetic and environmental implications during the late quaternary
(Elsevier, 2008)Rock magnetic concentration, grain size and mineralogy parameters together with organic carbon, calcium carbonate, redox-sensitive elements, delta sup(18) O of Globigerinoides ruber and radiocarbon dating were carried out ... -
Interannual variability of chlrophyll concentration in the eastern Arabian Sea
(MSc Dissertation, Pune University, India - National Institute of Oceanography, Goa, India; 65pp, 2008)The monthly mean chlorophyll pigment concentrations and diffuse attenuation were derived for the eastern Arabian Sea [5-16oN; 70-80oE] from SeaWiFS global 9-km resolution data product for the period January 1998 to December ... -
Propagation of sound in oceans
(MSc Dissertation, Wadia College, Pune, India - National Institute of Oceanography, Goa, India; 29pp, 2008)The present project work studies the characteristics of the sound speed profiles in the Arabian Sea and the Bay of Bengal. Since the sound speed in the ocean depends on the temperature and salinity, the vertical profiles ... -
Modelling of tidal hydrodynamics for a tropical ecosystem with implications for pollutant dispersion (Cochin Estuary, Southwest India)
(Springer, 2008)Tidal circulation in the Cochin Estuary, a moderately polluted estuary along the southwest coast of India, was studied using a 2D hydrodynamic model. The predicted tides and currents showed very good agreement with measured ...
