Impact of the Indian Summer Monsoon variability on the source area weathering in the Indo-Burman ranges during the last 21-kyr - A sediment record from the Andaman Sea
(Elsevier, 2019)The paleomonsoonal variations and their impact on the weathering patterns in the source regions of sediments of the Andaman Sea were investigated from a 21-kyr sedimentary record using environmental magnetic, clay mineralogical ... -
Extended distribution of Phtisica marina Slabber, 1769 (Crustacea: Amphipoda): first observation of alien Caprellid in the coastal waters of Indian subcontinent
(Regional Euro-Asian Biological Invasions Centre - REABIC, Helsinki, Finland, 2019)Phtisica marina, originally described by Slabber, 1769 from Netherlands, is one of the most abundant caprellid amphipod species reported from numerous regions around the globe and is primarily associated with fouling ... -
Spatiotemporal variation of alkaline phosphatase activity in coastal waters off Trivandrum
(Elsevier, 2019)Phosphatase is an extracellular enzyme which releases inorganic phosphate (Pi) from dissolved organic phosphate and indirectly organic carbon as nutrients for aquatic communities. Here, we have examined spatiotemporal ... -
Role of sulfur-oxidizing bacteria on the ecology in tropical mangrove sediments
(Elsevier, 2019)Mangroves are unique ecological niches for microorganisms which play major roles in biogeochemical cycles and in nutrient recycling. Sulfur compounds are primarily utilized by sulfur-oxidizing bacteria (SOB) and sulfate-reducing ... -
Metagenomic analysis of tarball-associated bacteria from Goa, India
(Elsevier, 2019)The beaches of Goa state in India are frequently polluted with tarballs, specifically during pre-monsoon and monsoon seasons. Tarballs contain hydrocarbons, including polycyclic aromatic hydrocarbons, which pose significant ... -
Gas transfer velocities of CO2 in subtropical monsoonal climate streams and small rivers
(European Geosciences Union, 2019)CO2 outgassing from rivers is a critical component for evaluating riverine carbon cycle, but it is poorly quantified largely due to limited measurements and modeling of gas transfer velocity in subtropical streams and ... -
Surface wave dynamics off Mumbai coast, north-eastern Arabian Sea
(Springer Berlin Heidelberg, 2019)Directional wave data collected in the coastal area at 10-m water depth for a period of 1 year is used to describe the surface wave dynamics off Mumbai coast. Partitioning of the wave spectrum into locally generated waves ... -
Implications of Microbial Thiosulfate Utilization in Red Clay Sediments of the Central Indian Basin: The Martian Analogy
(John Wiley & Sons, 2019)Microbial thiosulfate utilization and S-disproportionation could be important mechanisms of sulfate-formations on Earth and Mars. Sulfates on Mars date back to late-Noachian to Hesperian period. In contrast, the large ... -
Role of eddies on organic matter production and f-ratios in the Bay of Bengal
(Elsevier, 2019)In order to examine the sources of nutrients and f-ratios in the cyclonic (CE) and anticyclonic eddy (ACE), the content and isotopic composition of carbon and nitrogen in suspended particulate organic matter (POM) were ... -
Seasonal variability of sea-surface temperature fronts associated with large marine ecosystems in the north Indian Ocean
(Springer India, 2019)We use 14 years of satellite-derived sea-surface temperature (SST) data to compute a monthly frontal probability index (FPI) to determine the existence of a front in a pixel. A persistent SST front is deemed to exist if ... -
A new clionaid sponge infests live corals on the west coast of India (Porifera, Demospongiae, Clionaida)
(Taylor & Francis, 2019)Coral reef ecosystems depend on the balanced interplay of constructive and destructive processes and are increasingly threatened by environmental change. In this context bioeroding sponges play a significant role in carbonate ... -
A new species of Grandidierella Coutière, 1904, G. nioensis sp. nov. (Amphipoda, Aoridae), from the east coast of India
(Magnolia Press, Auckland, New Zealand, 2019)A new species of Grandidierella Coutière, 1904, G. nioensis is described from the east coast of India. It is close to G. mahafalensis Coutière, 1904, from Madagascar and G. halophilus Wongkamhaeng, Pholpunthin & Azman, ... -
CO2 fixation and production of biodiesel by Chlorella vulgaris NIOCCV under mixotrophic cultivation
(Elsevier, 2019)In this study, Chlorella vulgaris NIOCCV was cultivated in seafood processing industry wastewater with continuous supply of 5%, 10%, and 20% CO2. The optimum CO2 fixation efficiency (RCO2), biomass productivity, specific ... -
Features of locally and remotely generated surface gravity waves in the inner-shelf region of northwestern Bay of Bengal
(John Wiley & Sons, 2019)In this article, we studied the characteristics of locally and remotely generated wind waves in the inner-shelf region of northwestern Bay of Bengal (BoB) based on the measured wave data. Two well-differentiated wave ... -
Sedimentary sulphate reduction and organic matter mineralization across salinity gradient of the Mandovi Estuary, West coast of India
(Elsevier, 2019)The Mandovi Estuary, located along the tropical west coast of India, transforms from being a freshwater-dominated body during the monsoon season to a tide-dominated system during post-monsoon season, with a salinity gradient ... -
Hydrothermal Energy Transfer and Organic Carbon Production at the Deep Seafloor
(Frontiers, Switzerland, 2019)In just four decades, hundreds of hydrothermal vent fields have been discovered, widely distributed along tectonic plate boundaries on the ocean floor. Vent invertebrate biomass reaching up to tens of kilograms per square ... -
