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 ... -
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 ... -
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 ... -
Mechanisms of barrier layer formation and erosion from in situ observations in the Bay of Bengal
(2019)During the Bay of Bengal (BoB) Boundary Layer Experiment (BoBBLE) in the southern BoB, time series of microstructure measurements were obtained at 88N, 898E from 4 to 14 July 2016. These observations captured events of ... -
An integrated geophysical study east of the southern Chagos Laccadive Ridge Complex, Central Indian Ocean Basin: Implications for the Rodriguez Triple Junction dynamics in the Late Cretaceous
(2019)The Central Indian Ocean Basin, east of the southern Chagos Laccadive Ridge complex has evolved due to seafloor spreading in the N-S direction since the Late Cretaceous. The trace of the Rodriguez Triple Junction (RTJ)has ... -
On the physical interpretation of the lead relation between Warm Water Volume and the El Ni�o Southern Oscillation
(Springer Berlin Heidelberg, 2019)The Warm Water Volume (WWV), a proxy for the equatorial Pacific heat content, is the most widely used oceanic precursor of the El Ni�o Southern Oscillation (ENSO). The standard interpretation of this lead relation in the ... -
Improvement in biomass, lipid production and biodiesel properties of a euryhaline Chlorella vulgaris NIOCCV on mixotrophic cultivation in wastewater from a fish processing plant
(Elsevier, 2019)In this study, the changes in biomass productivity, wastewater treatment, lipid production and biodiesel properties from mixotrophic cultivation of Chlorella vulgaris NIOCCV in untreated wastewater from a fish processing ... -
Geometry of the Subducting Indian Plate and Local Seismicity in the Andaman Region from the Passive OBS Experiment
(Seismological Society of America, California, USA, 2019)We deployed a temporary passive ocean-bottom seismometer (OBS) network from 25 December 2013 to 15 May 2014 to understand the local seismicity pattern in the Andaman region. A total of 559 local earthquakes are identified ... -
Nitrate Reductase Gene Expression in Idiomarina Strain cos21 Obtained from Oxygen Minimum Zone of Arabian Sea
(Springer US, 2019)This study analyses the induction and repression of nitrate reduction activity in a batch culture of Idiomarina strain cos21. On a change from aerobic to anaerobic respiration, the culture entered a stationary phase. The ... -
