Comparison of bacterial community structure in coastal and offshore waters of the Bay of Bengal, India
(Elsevier BV, 2020)Bacterial community structure was analysed from the coastal and offshore surface waters of the Bay of Bengal (BoB) using of Next Generation Sequencing (NGS) approach. Taxonomic richness was high in the offshore waters ... -
Controls on organic matter distribution in oxygen minimum zone sediments from the continental slope off western India
(Elsevier B.V., 2020)The causes of organic-rich sediments in contact with the perennial oxygen minimum zone (OMZ) on the continental slope off western India have been debated extensively, largely in relation to two main controlling factors: ... -
Chemical characterization of wintertime aerosols over the Arabian Sea: Impact of marine sources and long-range transport
(Pergamon, 2020)We examined here the compositional characteristics of total suspended particulate (TSP) samples collected along the east coast of the Arabian Sea during a winter cruise (SS379: 6-24 December 2018) to understand the extent ... -
Occurrence of white gelatinous foam on the beaches of Kollam (southwest coast of India) due to the senescent bloom of Phaeocystis globosa
(Current Science Association, IAS, 2020)An unusual white gelatinous foam (~2 ft high) was detected on the beaches of Kollam (Mundakkal), Kerala, southwest coast of India. It extended to ~300 m alongshore on 10 June 2019 from 7 am and sustained till around 10 am. ... -
Prionospio atrovitta (Annelida: Spionidae), a new species from Andaman and Nicobar archipelago, northern Indian Ocean
(Taylor and Francis Ltd., 2020)A new species of polychaete, Prionospio atrovitta, is described from the sandy sediments of the Andaman and Nicobar insular margin. The major feature distinguishing P. atrovitta from other species of the genus Prionospio ... -
Signature of buried channels as deduced from subsurface GPR survey at Southwest coast of Tamil Nadu, India
(Springer, 2020)Buried channels are the subsurface geomorphic features, which illustrate the pattern and evolution of paleodrainage system in an area. Old topographical map (1967) of Kottumangalam coast of southwest Tamil Nadu, India, ... -
Late Quaternary Sedimentation and Slope Failure Events on the Costa Rican Margin
(Springer, Cham, 2020)The Costa Rican margin is an erosional convergent margin formed by subduction of the Cocos Plate under the Caribbean Plate along the Middle America Trench. The Integrated Ocean Drilling Program (IODP) Expedition 334 was ... -
Influence of salinity stress on bacterial community composition and β-glucosidase activity in a tropical estuary: Elucidation through microcosm experiments
(Elsevier Ltd, 2020)The influence of changing salinity on community composition and functional activity (Bacterial Production (BP) and ectoenzyme activity) of major bacterial taxa was evaluated using microcosm experiments in a tropical monsoon ... -
First barcodes of Bathynomus kensleyi (Lowry and Dempsey, 2006) and Bathynomus decemspinosus (Shih, 1972) from the Southeast coast of India
(Elsevier, 2020)Due to their large size, bathynomids (Crustacea, Isopoda, Cirolanidae), belonging to the �supergiant group� of isopods, have long been prominent. The distribution of giant isopods from inshore to deep-sea environments has ... -
Role of eddies on controlling total and size-fractionated primary production in the Bay of Bengal
(Elsevier BV, 2020)In order to examine the role of eddies on total and size-fractionated primary production, two cyclonic (CE), one anticyclonic (ACE) and no-eddy (NE) regions were sampled in the BoB during pre-summer monsoon (June 2019). ... -
Connecting land use-land cover and precipitation with organic matter biogeochemistry in a tropical river-estuary system of western peninsular India
(Academic Press, 2020)Organic matter (OM) composition changed due to land use - land cover (LULC) and hydrology modification, has distinctive linkage towards sustainable environment management in tropical river systems. It is crucial in small ... -
Modelling of Oil-Sediment Aggregates Trajectories Along Gulf of Khambhat, West Coast of India
(Springer, Singapore, 2021)Oil spill accidents on the marine waters impose great threat to the marine organism, humans and economic. Continuous efforts have been made to achieve effective mitigation measures to avoid the damage to the marine ... -
Diseases and pathogens of marine invertebrate corals in Indian reefs
(Academic Press Inc., 2020)Diseases in marine invertebrate corals have been reported worldwide and have been associated with infection by various microbial pathogens that cause massive mortality. Several bacterial species, especially Vibrio species ... -
Potential Impacts of Deep-Sea Mining on Ecosystems
(Oxford University Press, 2020)Deep-sea mining pertains to underwater minerals such as polymetallic nodules, ferromanganese crusts, and hydrothermal sulfides that are considered as alternative sources for metals such as Cu, Ni, Co, Pb, Zn, Cd, Mn, Fe, ... -
Variations in ?13C values of sedimentary organic matter since late Miocene time in the Indus Fan (IODP Site 1457) of the eastern Arabian Sea
(Cambridge University Press, 2020)A 1108.6 m long core was recovered at Site U1457 located on the Indus Fan in the Laxmi Basin of the eastern Arabian Sea during IODP Expedition 355. Shipboard examinations defined five lithologic units (I to V) of the lower ... -
Severe phosphate limitation on nitrogen fixation in the Bay of Bengal
