Autotrophic potential in mesophilic heterotrophic bacterial isolates from Sino-Pacific marine sediments
(Springer and Chinese Society of Oceanography, 2017)Microbial carbon fixation is a paramount process in the ocean especially below the photic zone both in water and sedimentary ecosystems. Autotrophic microbes that fix carbon dioxide are renowned. However, the question ... -
An integrated approach to study the biomarker responses in marine gastropod Nerita chamaeleon environmentally exposed to polycyclic aromatic hydrocarbons
(ISJ, 2017)Ecological risk assessment using multiple biomarkers produce a large amount of data that is hard to interpret and the result are often contradictory. In this context, Integrated Biomarker Response (IBR) index was used to ... -
Spatial distribution of dinoflagellates from the tropical coastal waters of the South Andaman, India: Implications for coastal pollution monitoring
(Elsevier, 2017)Dinoflagellate community structure from two semi-enclosed areas along the South Andaman region, India, was investigated to assess the anthropogenic impact on coastal water quality. At the densely inhabited Port Blair Bay, ... -
Observations of long-period waves in the nearshore waters of central west coast of India during the fall inter-monsoon period
(Elsevier, 2017)The waves measured in the eastern Arabian Sea during the fall inter-monsoon period (October) are examined at 4 locations during 2010–2015. Multi-modal features have been observed in measured wave spectra due to independent ... -
Patterns of primary production in the Red Sea
(Elsevier, 2017)This paper presents data on various parameters of primary production (chlorophyll concentration, carbon uptake, nitrogen uptake, phytoplankton groups) measured in 4 cruises in the Saudi Arabian waters of the Red Sea between ... -
Oyster reef restoration in controlling coastal pollution around India: A viewpoint
(Elsevier, 2017)Coastal waters receive large amounts of nutrients and pollutants from different point and nonpoint sources through bays and estuaries. Excess supply of nutrients in coastal waters may have detrimental effects, leading to ... -
Suspended matter and fluid mud off Alleppey, southwest coast of India
(Elsevier, 2017)Time series measurements on suspended particulate matter (SPM) were made at one non-mud bank (M1) and two mud bank stations (M2 and M3) off Alleppey, south west coast of India. The mean SPM was low in surface (6.2 mg/l) ... -
Offshore sediments record the history of onshore iron ore mining in Goa State, India
(Elsevier, 2017)Environmental magnetic and geochemical analyses combined with 210Pb dating were carried out on a sediment core off Goa from Arabian Sea to reconstruct the sedimentation history of last three and a half centuries and to ... -
Dynamics of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of Cochin estuary, India
(Elsevier, 2017)Polycyclic aromatic hydrocarbons (PAHs) showed significant seasonal dynamics in surface sediments of a tropical ecosystem (Cochin estuary, south west coast of India). Concentrations ranged from 304 to 5874 ngg<sup>-1</sup> ... -
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) ... -
