Copepod carcasses in a tropical estuary during different hydrographical settings
(Springer, 2016)Dead copepods (carcasses) are widespread in aquatic systems, but their scientific quantification is rare due to the difficulty in discriminating them from live ones. In this paper, we hypothesized that due to large spatial ... -

In situ oxygen isotope compositions in olivines of different types of cosmic spherules: An assessment of relationships to chondritic particles
(Elsevier, 2016)Cosmic spherules collected from deep sea sediments of the Indian Ocean having different textures such as scoriaceous (4), relict-bearing (16), porphyritic (35) and barred olivine (2) were investigated for petrography, as ... -
A new species of Heterospio (Annelida, longosomatidae) from the Indian Ocean
(2016)Knowledge about the taxonomy and distribution of the monogeneric polychaete family Longosomatidae Hartman, 1944 is limited in all parts of the world. A new species of the genus Heterospio Ehlers, 1874 (Annelida, Longosomatidae) ... -
Timing, cause and consequences of mid-Holocene climate transition in the Arabian Sea
(Elsevier, 2016)We reconstruct centennial scale quantitative changes in surface seawater temperature (SST), evaporation-precipitation (from Mg/Ca and delta18O of surface dwelling planktic foraminifera), productivity (from relative abundance ... -
Antibacterial activity of marine bacillus substances against V. cholerae and S. aureus and in vivo evaluation using embryonic zebrafish test system
(Indian Pharmaceutical Association, 2016)Cell free extracts of Bacillus subtilis subsp. spizizenii and B. thuringiensis isolated from hydrothermal vent region of Azorean Island Faial, North Atlantic Ocean showed antagonistic against V. cholera serogroup 01 and ... -
Prevalence of skeletal tissue growth anomalies in a scleractinian coral: Turbinaria mesenterina of Malvan Marine Sanctuary, eastern Arabian Sea
(Inter Research, 2016)Skeletal tissue growth anomalies (STAs) of corals are capable of causing considerable degradation of reef health. This study is the first report of growth anomalies in Turbinaria corals and the first descriptive study of ... -
The final spawning ground of Tachypleus gigas (Muller, 1785) on the east Peninsular Malaysia is at risk: A call for action.
(PeerJ, Inc, 2016)Tanjung Selongor and Pantai Balok (State Pahang) are the only two places known for spawning activity of the Malaysian horseshoe crab - Tachypleus gigas (Muller, 1785) on the east coast of Peninsular Malaysia. While the ... -
Indian contributions in the field of marine micropaleontology (2010-2015)
(Indian National Science Academy, 2016)An overview of the research contributions made during the last five years by the Indian scientists in the field of marine micropaleontology is presented. Large scale micropaleontological studies employing assemblages of ... -
Mass mortality of macrobenthos in a biodiverse rocky beach- Impact of a minor oil spill
(NISCAIR, CSIR, 2016)A field survey was carried immediately post an accidental oil spill at rocky intertidal zone of Uran. Mass mortality of macrobenthos was observed at spillage site whereas reference site harboured diverse and live macrobenthic ... -
Advances in marine geophysical studies of the Indian Ocean: Contributions from India (2010-2015)
(Indian National Science Academy, 2016)Indian scientists carrying marine geophysical research at different Earth Science institutions have made significant advances during the last six years (2012-2015) for understanding evolution of continental margins of India ... -
Unicellular cyanobacteria synechocystis accommodate heterotrophic bacteria with varied enzymatic and metal resistance properties
(WILEY-VCH Verlag GmbH & Co., 2016)The interactions between heterotrophic bacteria and primary producers have a profound impact on the functioning of marine ecosystem. We characterized the enzymatic and metal resistance properties of fourteen heterotrophic ... -
The tectonic origin of the Bay of Bengal and Bangladesh
(American Geophysical Union Publications, 2016)We are able to decipher the tectonic evolution of the Bay of Bengal, a puzzle which has not been satisfactorily solved in the past, and we are also able to shed new light on origin of the buried 85°E Ridge. We do so by ... -
Extraterrestrial components from deep sea sediments of Indian Ocean
(Indian National Science Academy, 2016)Two different types of extraterrestrial particulate matter collections were undertaken during the last few years-by using magnets encased in dredges that were dragged along the seafloor and by sieving massive quantities ... -
Inhibition of mixed-layer deepening during winter in the northeastern Arabian Sea by the West India coastal current
(Springer, 2016)Though the deep mixed layers (MLs) that form in the northeastern Arabian Sea (NEAS) during the winter monsoon (November–February) have been attributed to convective mixing driven by dry, cool northeasterly winds from the ... -
Exploration of shipwreck off Konark coast, Odisha- A preliminary study
(Indian Society for Prehistoric and Quaternary Studies, 2016)Archaeological findings suggest that ports of Odisha were well connected with other ports of the Indian subcontinent and Persian Gulf, Red Sea and Southeast Asian countries. In the course of maritime trade, many vessels ... -
Effects of bottom water oxygen concentrations on mercury distribution and speciation in sediments below the oxygen minimum zone of the Arabian Sea
(Elsevier, 2016)This study investigated the influences of varying dissolved oxygen (DO) levels in overlying bottom water, sediment grain size, total sedimentary organic carbon (C<sub>org</sub>), and total sedimentary sulfide concentrations ... -
Denitrification activity in mangrove sediments varies with associated vegetation
(Elsevier, 2016)To test the hypothesis that mangrove vegetation associated sediment characteristics could influence an ecologically important function such as denitrification, a study was carried out at the Divar mangrove ecosystem in ... -
Slow spreading ridges of the Indian Ocean: An overview of marine geophysical investigations
(Indian Geophysical Union, 2016)Sparse and non-availability of high resolution geophysical data hindered the delineation of accurate morphology, structural configuration, tectonism and spreading history of Carlsberg Ridge (CR) and Central Indian Ridges ... -
