Productivity controls on the redox variation in the southeastern Arabian Sea sediments during the past 18 kyr
(2019)Redox-sensitive elements (uranium, molybdenum and cadmium) and productivity proxies (total organic carbon, calcium carbonate and phosphorous) were analysed to assess the importance of productivity on redox variation for ... -
Note on the genus Lecanophryella (Ciliophora: Suctorea) with description of a new species from west coast of India
(2019)The article presents a review of the literature on known representatives of the genus Lecanophryella containing general characteristics of the members of this genus, information on morphology and data on distribution. ... -
Suppressed biological production in the coastal waters off Visakhapatnam, India under the impact of the very severe cyclonic storm Hudhud
(2019)Tropical cyclones generally enhance biological production due to the increase in nutrients input due to vertical mixing. In contrast, the very severe cyclonic storm (VSCS) Hudhud decreased primary production due to the ... -
Temperature- and size-associated differences in the skeletal structures and osculum cross-sectional area influence the pumping rate of contractile sponge Cinachyrella cf. cavernosa
(2019)Sponges alter the proportion of structural and morphological components such as spicule skeleton and number of oscula in response to environment, development and growth. Such mechanisms indicate morphological and physiological ... -
Distribution and geochemical fractionation of lead in the continental shelf sediments around India
(2019)This study provides the first, preliminary data on geochemical distribution and fractionation of Pb (a toxic heavy metal) in continental shelf sediments around India and identifies the factors that control geochemical ... -
Bacterial Community Composition Markedly Altered by Coastal Hypoxia
(2019)Monsoonal upwelling along south and central west coast of India leads to intense biological productivity. As a consequence of excess organic matter production following upwelling during June-October and low dissolved oxygen ... -
Uncertainties of the 50-year wave height estimation using generalized extreme value and generalized Pareto distributions in the Indian Shelf seas
(2019)Information about waves with specific return period in a region is essential for the safe design of marine facilities. In this study, significant wave height for 50-year return period is estimated using generalized extreme ... -
Coral reef restoration - A way forward to offset the coastal development impacts on Indian coral reefs
(2019)Globally, coral reefs are degrading rapidly due to the combined impact of wide-scale anthropogenic activities and climate change. Similarly, coral reefs in India are facing an existential threat because of intensified ... -
Microbial diversity in a coastal environment with co-existing upwelling and mud-banks along the south west coast of India
(2019)Upwelling and mud banks are two prominent oceanographic features in the coastal waters along the south west coast of India during the southwest monsoon (MON) season. The present study investigates the microbial diversity ... -
Distribution and dispersal of surface sediments on the continental margins of India
(2019)The vast area, varying climate regimes, diverse source terrain lithology of the mainland India generate complex weathering and erosional patterns and leads to diverse sediment distribution and dispersal on the surrounding ... -
Spatio-temporal variability in macrobenthic communities and trophic structure of a tropical estuary and its adjacent coastal waters
(2019)Spatio-temporal distribution of the macrobenthic community (> 500 ?m) and the trophic ecology of polychaetes were studied for a year in the Cochin estuary (CE) and its adjacent coastal waters. A profound influence of the ... -
Assessing the ecological preferences of agglutinated benthic foraminiferal morphogroups from the western Bay of Bengal
(2019)Agglutinated benthic foraminiferal morphogroups have often been used as a proxy in paleoecological studies. The response of various agglutinated morphogroups may, however, vary regionally. Here we report the ecological ... -
Humpback whale singing activity off the Goan coast in the Eastern Arabian Sea
(2019)For over two decades, passive acoustic monitoring (PAM) methods have been successfully employed around the world for studying aquatic megafauna. PAM-driven studies in Indian waters have so far been relatively very scarce. ... -
Photocatalytic degradation of synthetic dyes using iron (III) oxide nanoparticles (Fe 2 O 3 -Nps) synthesised using Rhizophora mucronata Lam
(2019)Biosynthesis of nanoparticles through plant extracts is gaining attention due to the toxic free synthesis process. The environmental engineering applications of many metal oxide nanoparticles have been reported. In this ... -
Factors controlling organic matter composition and trophic state in seven tropical estuaries along the west coast of India
(2019)To understand the organic matter (OM) sources and trophic states, spatial and seasonal (post-monsoon and pre-monsoon) variation in sedimentary OM compositions was investigated in seven tropical estuaries of the state of ... -
Detailed Structure and Plate Reconstructions of the Central Indian Ocean Between 83.0 and 42.5 Ma (Chrons 34 and 20)
(2019)The Central Indian Ocean, namely the Central Indian, Crozet, and Madagascar basins, formed by rifting and subsequent drifting of India (now Capricorn), Antarctica, and Africa (now Somalia). We gathered a comprehensive set ... -
Impact of eddies on dissolved inorganic carbon components in the Bay of Bengal
(2019)To examine the influence of anticyclonic (ACE) and cyclonic (CE) eddies on variations in hydrographic properties and total inorganic carbon system (CT), a study was conducted in the western Bay of Bengal (BoB). The depth ... -
Oxygen isotopic and chemical composition of chromites in micrometeorites: Evidence of ordinary chondrite precursors
(2019)We identified 66 chromite grains from 42 of ~5000 micrometeorites collected from Indian Ocean deep-sea sediments and the South Pole water well. To determine the chromite grains precursors and their contribution to the ... -
Consistency of wave power at a location in the coastal waters of central eastern Arabian Sea
(2019)Wave energy assessment at a regional scale is required for planning installation of wave energy converters. Based on continuously measured wave data at 14-m water depth in the central eastern Arabian Sea from January 2011 ... -
Anti-Biofilm Activity of Biosurfactant Derived from Halomonas sp., a Lipolytic Marine Bacterium from the Bay of Bengal
(2019)Abstract: Halophilic bacteria isolated from sediment samples of five oil drilling sites in the Bay of Bengal (BOB) were screened for their biosurfactant-producing ability and for lipase production. The anti-biofilm activity ...
