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 ... -
Reconstruction of Late Pleistocene and Holocene Sea Level Curve for the East Coast of India
(2019)Holocene sea level curve has been generated for the East Coast of India. About seventy five 14C dates which are available from published works on coastal plains and offshore regions of the East Coast were considered and ... -
Impact of monsoon-induced discharge on phytoplankton community structure in the tropical Indian estuaries
(2019)To understand the influence of monsoon-induced river discharge and associated environmental changes on phytoplankton community structure in the Indian estuaries, physical and biogeochemical parameters were collected from ... -
Geochemical characteristics of submarine rhyolitic pumice from Andaman subduction zone: Inferences on magmatism and tectonics of north?eastern Indian Ocean
(2019)This paper reports new geochemical data for submarine volcanic pumice sampled from two volcanoes (SM?1 and SV?1) which are part of the Andaman subduction system. SM?1 volcano is located closer to the Andaman back?arc ... -
Role of eddies in structuring the mesozooplankton composition in coastal waters of the western Bay of Bengal
(2019)The mesozooplankton community structure of a cold core eddy, moving through a coastal location (Bheemunipatnam) in the western Bay of Bengal (BoB), was studied continuously for 17 days (21st February to 8th March 2016) ... -
Is there an effect of Bay of Bengal salinity on the northern Indian Ocean climatological rainfall?
(2019)The northern Bay of Bengal (BoB) receives a large amount of freshwater directly from monsoonal rains over the ocean, and indirectly through river runoffs. It has been proposed that the resulting strong salinity stratification ... -
Neuroendocrine and immunotoxicity of polyaromatic hydrocarbon, chrysene in crustacean post larvae
(2019)Polyaromatic hydrocarbons are a group of chemical pollutants which cause a significant threat to the living organisms in estuaries and marine ecosystems. We report the effect of chrysene, a major PAH pollutant found in ... -
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 ... -
