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 ... -
Organic carbon, and not copper, controls denitrification in oxygen minimum zones of the ocean
(Elsevier, 2008)Incubation experiments under trace metal clean conditions and ambient oxygen concentrations were used to investigate the response of microbial assemblages in oxygen minimum zones (OMZs) to additions of organic carbon and ... -
Treatment of colored effluents with lignin-degrading enzymes: An emerging role of marine-derived fungi
(Informa Healthcare, 2008)Some of the industries that discharge highly colored effluents are paper and pulp mills, textiles and dye-making industries, alcohol distilleries, and leather industries. Terrestrial white-rot basidiomycetous fungi and ... -
Impact of lower plate structure on upper plate deformation at the NW Sumatran convergent margin from seafloor morphology
(Elsevier, 2008)Results from multibeam bathymetric data acquired during 2005 and 2006, in the region of maximum slip of the 26 Dec. 2004 earthquake (Mw 9.2) are presented. These data provide high-resolution images of seafloor morphology ... -
T-antigen binding lectin with antibacterial activity from marine invertebrate, sea cucumber (Holothuria scabra): Possible involvement in differential recognition of bacteria
(Elsevier, 2008)In invertebrates, cellular and humoral components are evolved to maintain their body immunity and integrity. Both these factors respond to different antigens such as microorganisms, vertebrate erythrocytes and foreign ... -
The Indian Ocean
(Elsevier, 2008)There are two unique aspects of geography of the Indian Ocean that profoundly influence its climate and circulation: (a) The Indian Ocean’s northern expanse is curtailed by the Eurasian landmass around the Tropic of Cancer ... -
Seasonal and inter-annual variability of remotely-sensed sea surface height, visible light and chlorophyll in the Bay of Bengal
(MSc Dissertation, Goa University, Goa, India - National Institute of Oceanography, Goa, India; 41pp, 2008)Global warming and associated climate change is one of the immediate threats that the human being are confronted with and it is important to understand so that effective remedial measures could be put in place. The response ... -
