Ventilation of Oxygen to Oxygen Minimum Zone Due to Anticyclonic Eddies in the Bay of Bengal
(John Wiley & Sons, 2018)Intense oxygen minimum zone (OMZ) occurs in the middepth of the Eastern Tropical Pacific (ETP), Arabian Sea (AS), and Bay of Bengal (BoB). However, the occurrence of anammox/denitrification was reported only in the ETP and ... -
A Review on the Phylogeography of Potentially Chemoautotrophic Bacteria from Major Vent and Seep Fauna and Their Contribution to Primary Production
(Taylor & Francis, 2018)Though geochemically and microbially well-defined, the phylogeographic data of microbial symbionts in these highly productive vent and seep systems require a closer examination and synthesis. QIIME analysis of 16S rDNA of ... -
Spatio-temporal variability in the sources of particulate organic carbon and nitrogen in a tropical Godavari estuary
(Elsevier, 2018)In order to evaluate the impact of seasonal river discharge on the spatio-temporal variability in the major sources of particulate organic matter (POM) in the tropical Godavari estuary, India, a comprehensive study was ... -
Development of multi-channel data logger for passive acoustic measurements
(Acoustical Society of India, 2018)Recording of passive acoustic data involves a listening device along with an instrumentation system. The passive listening device transforms mechanical disturbances to electrical signals. The subsequent sampling and logging ... -
Quantitative analyses of denitrifying bacterial diversity from a seasonally hypoxic monsoon governed tropical coastal region
(Elsevier, 2018)Microbial community mediated denitrification leads to nitrate reduction and, its eventual removal from marine ecosystems. Therefore, it is necessary to understand the functional diversity in terms of the abundance and types ... -
Seasonality and vertical distribution of epiphytic diatoms on the pneumatophore surface of mangrove Avicennia officinalis L.
(Springer Berlin Heidelberg, 2018)Mangrove pneumatophores (respiratory roots) form a unique habitat about which very little ecological information is available. In this study, epiphytic diatoms on the pneumatophore surface of Avicennia officinalis (L.) ... -
Responses of the picophytoplankton community to temperature fronts in the northeastern Arabian Sea during the northeast monsoon
(Elsevier, 2018)We investigated the responses of the picophytoplankton (< 3-μm) community to a temperature filament and front through high resolution spatial (~ 1 NM) sampling (November-23 to December-11, 2012) in the northeastern Arabian ... -
Developing community-based scientific priorities and new drilling proposals in the southern Indian and southwestern Pacific oceans
(Copernicus Gesellschaft MBH, Gottingen, Germany, 2018)An International Ocean Discovery Program (IODP) workshop was held at Sydney University, Aus-tralia, from 13 to 16 June 2017 and was attended by 97 scientists from 12 countries. The aim of the workshop was to investigate ... -
Biogeochemistry of methane in a tropical monsoonal estuarine system along the west coast of India
(Elsevier, 2018)Estuaries are known to be important sources of methane (CH4) to the atmosphere. However, a lack of adequate field studies in understanding the sources/sinks of CH4 in estuaries hampers the global atmospheric budgeting. ... -
Estimation of potential tidal energy along the west coast of India
(World Scientific, 2017)Tidal energy is one of the clean and non-depleting renewable energy sources. In contrast to other clean sources, such as wind, solar, geothermal etc., tidal energy can be predicted for years ahead. Also, the medium, seawater, ... -
Significance of metabolically active bacterioplankton in the frontal regions of the Northeastern Arabian Sea
(Springer International Publishing, 2018)The Northeastern Arabian Sea (NEAS) experiences convective mixing during winter monsoon, which facilitates nutrient enrichment in the surface layers. This region is also known to harbour several sea surface temperature ... -
Diversity and distribution of echinoderms in the South Eastern Arabian Sea shelf under the influence of seasonal hypoxia
(Elsevier, 2018)The South Eastern Arabian Sea (SEAS) margin represents a tropical eastern boundary upwelling system, which is subjected to intense seasonal hypoxia in the continental shelf, and impingement of oxygen minimum zone (OMZ) ... -
An Algorithm to Determine the Slope of the Spectral Absorption of Colored Dissolved Organic Matter (CDOM) and Detritus
(Springer India, 2018)A simple method to determine the slope of spectral variations of combined absorption of the colored dissolved organic matter and detritus (CDM) is presented. This method uses the slope of total absorption spectrum excluding ... -
Diversity and abundance of denitrifying and anammox bacteria from the Arabian Sea oxygen minimum zone
(Elsevier, 2018)Bacterial community involved in nitrogen transformations in the oxygen minimum zones (OMZ) with dissolved oxygen (DO) levels below 0.5-ml-L-1 is ascribed to be responsible for the reported 40% losses of fixed nitrogen. The ... -
Variations in concentrations and sources of bioavailable organic compounds in the Indian estuaries and their fluxes to coastal waters
(Elsevier, 2018)Estuarine organic matter (EOM) supports heterotrophic carbon demand in the estuaries. However, the fraction of bioavailable organic compounds, which are easily assimilated by biological organisms, in the EOM is unclear. ... -
Spectral Wave Characteristics in the Nearshore Waters of Northwestern Bay of Bengal
(Springer International Publishing, 2018)The spectral wave characteristics in the nearshore waters of northwestern Bay of Bengal are presented based on the buoy-measured data from February 2013 to December 2015 off Gopalpur at 15-m water depth. The mean seasonal ... -
Variations in Denitrification and Ventilation Within the Arabian Sea Oxygen Minimum Zone During the Holocene
(John Wiley & Sons, 2018)The continental slope of India is exposed to an intense perennial oxygen minimum zone (OMZ) supporting pelagic denitrification. Sediments that are presently in contact with the lower boundary of the denitrification zone ... -
