Post decomposition effect of water hyacinth on marine phytoplankton - A laboratory study
(NISCAIR-CSIR, India, 2018)Solutions obtained from post decomposition of different parts of water hyacinth were diluted with filtered seawater into different concentration (10%, 40%, and 60%) and used for the culture of Skeletonema costatum and ... -
Impact of Rossby waves on chlorophyll variability in the southeastern Arabian Sea
(Taylor & Francis, 2018)We use remotely sensed ocean colour data to show that Rossby waves are associated with the westward migration of chlorophyll distribution patterns in the southeastern Arabian Sea (SEAS). During the winter monsoon ... -
Genetic and functional diversity of double-stranded DNA viruses in a tropical monsoonal estuary, India
(Nature Publishing Group, 2018)The present study illustrates the genetic diversity of four uncultured viral communities from the surface waters of Cochin Estuary (CE), India. Viral diversity inferred using Illumina HiSeq paired-end sequencing using a ... -
Notes on Indian species of Calvatia and Langermannia including Calvatia natarajanii sp. nov.
(Magnolia Press, Auckland, New Zealand, 2018)A new species, Calvatia natarajanii, is presented as well as brief notes on the distribution of Calvatia sensu stricto and Langermannia in India. Calvatia natarajanii is distinguished by basidiomes having yellowish white ... -
Benthic fluxes of methane along the salinity gradient of a tropical monsoonal estuary: Implications for CH4 supersaturation and emission
(Elsevier, 2018)Observations in the Mandovi estuary, a typical tropical monsoonal estuary located on the west coast of India, revealed that waters were perennially supersaturated with CH4, indicating that the estuary could be a significant ... -
Dominant Modes of Upper Ocean Heat Content in the North Indian Ocean
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2018)The thermal energy needed for the development of hurricanes and monsoons as well as any prolonged marine weather event comes from layers in the upper oceans, not just from the thin layer represented by sea surface temperature ... -
Molecular diversity of marine pigmented bacteria in the central Arabian Sea with special reference to antioxidant properties
(Station Biologique de Roscoff, 2018)Pigmented bacteria (PIGB) from marine environment a rerecognized to impart protective action a gainst oxidative stress-induced cell damages. Since very little is known about their diversity and antioxidant potential, we ... -
Dominant Biological Control Over Upwelling on pCO2 in Sea East of Sri Lanka
(John Wiley & Sons, 2018)Upwelling enhances pCO2 levels due to injection of carbon-rich water to the surface despite the removal of carbon due to increase in primary production supported by enhanced nutrients. It is hypothesized that in the Bay ... -
New to total primary production ratio (f-ratio) in the Bay of Bengal using isotopic composition of suspended particulate organic carbon and nitrogen
(Elsevier, 2018)Variations in the content and isotopic compositions of carbon and nitrogen in the suspended particulate matter were analysed to identify sources of nutrients and compute f-ratios (ratio of new production to primary production) ... -
High Incidence of Lysogeny in the Oxygen Minimum Zones of the Arabian Sea (Southwest Coast of India)
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2018)Though microbial processes in the oxygen minimum zones (OMZs) of the Arabian Sea (AS) are well documented, prokaryote-virus interactions are less known. The present study was carried out to determine the potential ... -
18S rDNA sequencing data of benthic polychaetes from the Eastern Arabian Sea
(Elsevier, 2018)The limited DNA sequence data of the polychaetes species are available from the Eastern Arabian Sea. We have sequenced 18S rDNA gene from 54 polychaetes species and 37 species identified up to the species level. The DNA ... -
An updated checklist of echinoderms of the southeastern Arabian Sea
(Springer Berlin Heidelberg, 2018)The southeastern Arabian Sea (SEAS) is a distinct ecosystem within the northern Indian Ocean, with unique physical, chemical and biological attributes. This paper provides comprehensive documentation on echinoderm diversity ... -
Detection of Intraseasonal Oscillations in SMAP Salinity in the Bay of Bengal
(John Wiley & Sons, 2018)Analysis of Soil Moisture Active Passive (SMAP) mission derived sea surface salinity (SSS) during April 2015 to December 2017 in the Bay of Bengal (BoB) shows first revelation of new insight of existence of 30- to 90-day ... -
Regioselective synthesis of pyrrole and indole-fused isocoumarins catalysed by N-O chelate ruthenium(II) complex
(Springer India, 2018)Heterocyclic compounds containing pyrrole and indole-fused isocoumarins were obtained from a one-pot synthesis via annulations of N-heterocyclic carboxylic acids and alkynes with N-O chelate ruthenium(II) complex, ... -
Dynamics of size-fractionated phytoplankton biomass in a monsoonal estuary: Patterns and drivers for seasonal and spatial variability
(Elsevier, 2018)Phytoplankton size-fractionated biomass is an important determinant of the type of food web functioning in aquatic ecosystems. Knowledge about the effect of seasonal salinity gradient on the size-fractionated biomass ... -
Quantitative estimation of elemental composition employing a synthetic generated spectrum
(The Optical Society, USA, 2018)Composition of multielement samples is estimated by using a synthetic generated spectrum utilizing a nonlinear fitting routine. By fitting simultaneously a large number of emission lines, the error in the estimation is ... -
Impact of seasonal monsoon on coastal weather condition: a case study at Vengurla, west coast of India
