New and primary production in the western Indian Ocean during fall monsoon
(2019)
To examine the spatial variability and controlling factors of new, regenerated and primary productions, 21 stations were studied during fall monsoon period in the western Indian Ocean under Indian-GEOTRACES program. The ...
Gregarious true- colonies of ciliate Vorticella oceanica on a chain forming diatom Chaetoceros coarctatus: indicating change in the nature of association
(2019)
Eco-commensal association between the chain forming planktonic diatom Chaetoceros coarctatus and the peritrich aloricate ciliate Vorticella oceanica is well known in tropical waters. This epibiosis provides several advantages ...
Weight-length relationship, morphometric and meristic characters of the yellow seahorse Hippocampus kuda Bleeker, 1852 (Syngnathiformes: Syngnathidae) from central west coast of India
(2019)
Eighteen morphometric and five meristic characters of the yellow seahorse Hippocampus kuda Bleeker, 1852 inhabiting the coastal waters of Ratnagiri, central west coast of India, were studied. Morphometric/numerical analysis ...
New records of epibiont Thecacineta calix (Ciliophora: Suctorea) from the Caspian Sea and Angriya Bank, Arabian Sea
(2019)
The suctorian Thecacineta calix is reported from an abandoned exploration well of northern Caspian Sea and from Angriya Bank, India, Arabian Sea, as epibiont on halacarid mites and nematodes, respectively. This is the first ...
Genetic variation of reef-building polychaete Sabellaria chandraae in the south-eastern Arabian Sea based on mitochondrial COI gene
(2019)
The honeycomb worm Sabellaria chandraae is the most common reef-building polychaete in the intertidal area along the south-eastern Arabian Sea. We used the mitochondrial cytochrome c oxidase subunit I (mtCOI) gene to examine ...
Mineralogical and geochemical variation in hydrothermal sulfides from Vienna Woods field, Manus Basin, Papua New Guinea: constraints on their evolution
(The Chinese Society of Oceanography, 2018)
Polymetallic sulfides from two hydrothermal chimneys and talus deposit from the Vienna Woods field of Manus Basin were studied for mineralogy, elemental composition, and S-isotope ratio to understand their evolution. The ...
Fucoxanthin and pheophytin-a from the marine algae Sargassum cinereum: Isolation, characterization and their feeding deterrent activity on Shrimps
(Indian Chemical Society, 2019)
Chemical investigation of the brown alga Sargassum cinereum collected from Goa coast, India led to the isolation of two bioactive pigments viz. pheophytin-a and fucoxanthin in a relatively good concentration. These pigments ...
Inverted sediments in the coastal Antarctic lake: Evidence of paleostorm?
(Elsevier, 2018)
The faunal (foraminiferal and diatom abundance) and sedimentological analysis was carried out on two cores collected from a coastal lake in the Vestfold Hills region of Antarctica. Out of a couple of cores collected from ...
Changes in the soft-bottom macrobenthic diversity and community structure from the ports of Mumbai, India
(Springer, 2013)
Soft-bottom macrobenthic diversity and community structure were assessed at Mumbai and Jawaharlal Nehru ports during three different periods between 2001 and 2002 (November 2001 post-monsoon 1, April/May 2002 pre-monsoon, ...
Numerical simulations of barnacle larval dispersion coupled with field observations on larval abundance, settlement and recruitment in a tropical monsoon influenced coastal marine environment
(Elsevier, 2012)
Observations were carried out to monitor the larval abundance, settlement and recruitment of barnacles on a regular basis for a period of two years. The results were then compared with the numerical modelling studies carried ...
