Formation of methane-related authigenic carbonates in a highly dynamic biogeochemical system in the Krishna–Godavari Basin, Bay of Bengal
(Elsevier, 2015)We report the abundant occurrence of authigenic Fe-rich carbonate, high Mg-calcite (HMC) and low Mg-calcite from 11 cores recovered from the Krishna–Godavari Basin (K–G Basin), Bay of Bengal. The cores were collected as ... -
A new subspecies of Phascolion Theel, 1875 (Sipuncula: Golfingiidae) from Indian waters
(Magnolia Press, 2015)A new subspecies of Phascolion pacificum Murina, 1957 is described from shallow waters (15–20 m deep) off Malvan and Ratnagiri in India. Phascolion pacificum denticulatum ssp. nov. is characterized by the presence of a ... -
Secondary calcification of planktic foraminifera from the Indian sector of Southern ocean
(Geological Society of China, 2015)This study focused on planktic foraminifera in plankton tows and surface sediments from the western Indian sector of Southern Ocean in order to evaluate the potential foraminiferal secondary calcification and/or dissolution ... -
Sea-level-rise trends off the Indian coasts during the last two decades
(Current Science Association, 2015)The present communication discusses sea-level-rise trends in the north Indian Ocean, particularly off the Indian coasts, based on estimates derived from satellite altimeter and tide-gauge data. Altimeter data analysis over ... -
Science and Policy
(Current Science Association, 2015)A report on the meeting `Policy for Science and Science for Policy’ held at the National Institute of Advanced Studies, Bengaluru between 15 and 19 December 2014. -
Deproteination of shrimp shell wastes using immobilized marine associated pseudomonad Amet1776
(Oriental Scientific Publishing, 2015)Chitin is a naturally abundant amino polysaccharide found in the shell of crustaceans, insects etc. It has become of great interest because of their biological, industrial and biomedical applications. Shrimp by product has ... -
Flavonoids from Rhizophora conjugata fruit extract blocks virulence factors of Pseudomonas aeruginosa
(GSTF, 2015)Pseudomonas aeruginosa is a major nosocomial pathogen which causes hospital acquired infections and recently has gained importance as a model to study antibiotic resistance. In the present study, we investigated the effect ... -
Disseminated sulphides in basalts from the northern central Indian ridge: Implications on late-stage hydrothermal activity
(Springer, 2015)This study examined the mineralogy and mineral chemistry of disseminated sulphides (mainly chalcopyrite-pyrite) in partly altered basalts from the northern Central Indian Ridge, Indian Ocean in order to understand the role ... -
Sources, distribution and preservation of organic matter in a tropical estuary (Godavari, India)
(Springer, 2015)Major sources and distribution of organic matter (OM) were examined in a tropical monsoonal estuary, the Godavari, using content and isotopic signatures in suspended particulate matter and surface sediments during no-discharge ... -
Apparent grazing losses of Labyrinthulomycetes protists in oceanic and coastal waters: An experimental elucidation
(Springer, 2015)Labyrinthulomycetes are unicellular eukaryotes known for their ability to synthesize polyunsaturated fatty acids that are essential for growth and development of zooplankton. But relationship of these microorganisms with ... -
Bacterial domination over Archaea in ammonia oxidation in a monsoon-driven tropical estuary
(Springer, 2015)Autotrophic ammonia oxidizing microorganisms,which are responsible for the rate-limiting step of nitrification in most aquatic systems, have not been studied in tropical estuaries. Cochin estuary (CE) is one of the largest, ... -
Inter-annual variations in wave characteristics off Ratnagiri, Northeast Arabian Sea
(Elsevier, 2015)The wave data measured using the Datawell directional wave rider buoy at 13 m water depth off Ratnagiri during 2010 to 2013 is used to study the inter-annual variations in the wave characteristics. The percentage occurrence ... -
Magma production rate along the Ninetyeast Ridge and its relationship to Indian plate motion and Kerguelen hot spot activity
(American Geophysical Union, 2015)The Ninetyeast Ridge, a linear trace of the Kerguelen hot spot in the Indian Ocean, was emplaced on a rapidly drifting Indian plate. Magma production rates along the ridge track are computed using gravity-derived excess ... -
Plate tectonic reconstruction of India and Madagascar closing through the Mascarene Basin
(Ocean Society of India, 2015)The western continental margin of India was formed due to the rifting and drifting among India, Madagascar and Seychelles. Several researchers provided relative configuration of India and Madagascar in their pre-break-up ... -
Optical closure of apparent optical properties in coastal waters off Goa
(Indian Society of Remote Sensing, 2015)Inherent and apparent optical properties were measured for coastal waters off Goa, a site on the west coast of India using the in-situ measuring profiling optical instruments. The optical closure was obtained using the ... -
Distribution and abundance of benthic macroorganisms in and around Visakhapatnam Harbour on the east coast of India
(Marine Biological Association of the United Kingdom, 2015)Benthic communities form an important component of the marine food chain. Their occurrence also provides information on the health of the ecosystem. A study was carried out to understand the distribution and abundance of ... -
Field and laboratory investigations of budding in the tetillid sponge Cinachyrella cavernosa
