Grazing of particle-associated bacteria - An elimination of the non-viable fraction
(Elsevier, 2017)Quantification of bacteria being grazed by microzooplankton is gaining importance since they serve as energy subsidies for higher trophic levels which consequently influence fish production. Hence, grazing pressure on ... -
Newly discovered deep-branching marine plastid lineages are numerically rare but globally distributed
(Current Biology, 2017)Ocean surface warming is resulting in an expansion of stratified, low-nutrient environments, a process referred to as ocean desertification [1]. A challenge for assessing the impact of these changes is the lack of robust ... -
Internal structure of the 85°E ridge, Bay of Bengal: Evidence for multiphase volcanism
(Elsevier, 2017)The 85°E Ridge, located in the Bay of Bengal of the northeastern Indian Ocean is an enigmatic geological feature as it possesses unusual geophysical signatures. The ridge's internal structure and mode of eruptions are ... -
A unique corundum and refractory metal-nugget bearing micrometeorite P117
(The Meteoritical Society, 2017)Micrometeorites provide a large range of samples sourced from a wide variety of planetary materials, thereby providing a scope for expanding the known inventory of solar system materials. Here we report the micrometeorite ... -
Internal waves over the shelf in the western Bay of Bengal: A case study
(Springer, 2017)Generation and propagation of internal waves (IWs) in the coastal waters of the extended shelf of the western Bay of Bengal are investigated for late winter by using the Massachusetts Institute of Technology General ... -
N2 production rates limited by nitrite availability in the Bay of Bengal oxygen minimum zone
(Macmillan Publishers Limited, 2017)A third or more of the fixed nitrogen lost from the oceans as N<sub>2</sub> is removed by anaerobic microbial processes in open ocean oxygen minimum zones. These zones have expanded over the past decades, and further ... -
TNF-a and IL-6 inhibitory effects of cyclic dipeptides isolated from marine bacteria Streptomyces sp.
(Springer and Business Media, 2017)Inflammation is mediated by a variety of soluble factors, including a group of secreted polypeptides known as cytokines. The anti-inflammatory cytokines are a series of immune regulatory molecules that control the pro ... -
Elucidation of the tidal influence on bacterial populations in a monsoon influenced estuary through simultaneous observations
(Springer, 2017)The influence of tides on bacterial populations in a monsoon influenced tropical estuary was assessed through fine resolution sampling (1 to 3 h) during spring and neap tides from mouth to the freshwater end at four stations ... -
Microbial community structure of surface sediments from a tropical estuarine environment using next generation sequencing
(Elsevier, 2017)Microbial community structure was analyzed from tropical monsoon influenced Mandovi-Zuari (Ma-Zu) estuarine sediment by means of Next Gen Sequencing (NGS) approach using Ion Torrent PGM™. The sequencing generated 80,282 ... -
Anaerobic carbon mineralisation through sulphate reduction in the inner shelf sediments of eastern Arabian sea
(Springer, 2017)Monsoon-induced coastal upwelling, land run-off, benthic and atmospheric inputs make the western Indian shelf waters biologically productive that is expected to lead to high rates of mineralisation of organic matter (OM) ... -
Contrasting Chl-a responses to the tropical cyclones Thane and Phailin in the Bay of Bengal
(Elsevier, 2017)Satellite-derived ocean colour data was used to identify the phytoplankton bloom associated with tropical cyclones Thane and Phailin in the Bay of Bengal (BoB). Cyclone Thane was category 2 cyclone (25-31 December 2011), ... -
Regulating gonad inhibition and vitellogenin/vitellin induction in Penaeus monodon using mature GIH fusion protein and polyclonal antisera
(Elsevier, 2017)Gonad inhibiting hormone (GIH), type II class of the CHH family neuropeptides, is released by the neurohaemal XO-SG complex of the eyestalk. The inhibitory function of GIH has a pivotal role in gonad development and ... -
Global concerns of ship`s ballast water mediated translocation of bacteria
(Springer and Business Media, 2017)Shipping facilitates transportation of over 90% of the world’s commodities and eventually transfers ~10 billion tons of ballast water which is routinely taken aboard vessels to maintain their stability. The ballast water ... -
Assessing metal contamination in recent creek sediments using fractionation technique along Mumbai coast, India
(Springer and Business Media, 2017)Three sediment cores from a creek environment in Mumbai, extending from the head to the creek mouth, were studied with respect to elements (Fe, Mn, Cu, Pb, Co, Zn and Cr) along with organic matter (total organic carbon, ... -
Carbonate preservation during the 'mystery interval' in the northern Indian Ocean
(Terra Scientific Publishing Company, 2016)To understand carbonate dissolution and/or preservation on the sea floor since the Last Glacial Maximum (LGM), we measured shell weights of planktonic foraminifera Globigerinoides ruber from four sediment cores retrieved ... -
Seabed resident event driven profiling system (SREP). Concept, design and tests
(IEEE, 2016)The seabed resident event driven profiling system (SREP) described here offers a novel, optimized approach to profiling in coastal waters from seabed to sea surface during the rough seas encountered in the southwest monsoon ... -
Perspectives on the terrestrial organic matter transport and burial along the land-deep sea continuum: Caveats in our understanding of biogeochemical processes and future needs
(Frontiers Media, 2016)The natural carbon cycle is immensely intricate to fully understand its sources, fluxes and the processes that are responsible for their cycling in different reservoirs and their balances on a global scale. Anthropogenic ... -
The ITS-based phylogeny of fungi associated with tarballs
(Elsevier, 2016)Tarballs, the remnants of crude oil which change into semi-solid phase due to various weathering processes in the sea, are rich in hydrocarbons, including toxic and almost non-degradable hydrocarbons. Certain microorganisms ... -
Gravity anomalies over the central Indian ridge between 3 degree S and 11 degree S, Indian Ocean: Segmentation and crustal structure
(Indian Academy of Sciences, 2016)High-resolution shipboard geophysical investigations along the Indian Ocean ridge system are sparse especially over the Carlsberg and Central Indian ridges. In the present study, the shipboard gravity and multibeam bathymetry ... -
Evolution to decay of upwelling and associated biogeochemistry over the southeastern Arabian sea shelf
(AGU Publications, 2016)Observations along 10 shelf transects in 2012 near 10°N in the southeastern Arabian Sea revealed the usual warm oligotrophic conditions during the winter monsoon and upwelling of oxygen-deficient, nutrient-rich cool water ...
