Elevated turbidity and dissolved manganese in deep water column near 10�47�S Central Indian Ridge: studies on hydrothermal activities
(Springer Science and Business Media Deutschland GmbH, 2020)
The deep water in the ridge segment between 10°18'S and 10°57'S of northern Central Indian Ridge was surveyed with CTD and AUV for seafloor hydrothermal activities. During the survey, 25 CTD hydrocasts were made, and ...
Phytoplankton chlorophyll-breakdown pathway: Implication in ecosystem assessment
(2020)
The chlorophyll-breakdown to pheophorbide is determined by biotic factors such as grazing (via chlorophyllide) or senescence (via pheophytin). So far, much of the information on chlorophyll-breakdown is available from ...
Influence of hypoxia on phosphorus cycling in Alappuzha mud banks, southwest coast of India
(2020)
The southwest coast of India is known to experience two concurrent processes during the southwest monsoon, namely coastal upwelling and mud banks at selected stretches such as that off Alappuzha. The mud bank sediments ...
Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal
(Springer Verlag, 2020)
Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ...
Contrasting sulfidization in the turbidite and hemipelagic sediments of Bengal Fan
(Elsevier Ltd, 2020)
We report for the first time, contrasting sulfidization profiles in a sedimentary sequence comprising of clay-silt turbidites and hemipelagic dominated deposits in a channel-levee complex of the middle Bengal Fan. The ...
Inhibition of pathogenic Vibrio harveyi using calamenene, derived from the Indian gorgonian Subergorgia reticulata, and its synthetic analog
(Springer, 2020)
We report the synthesis and antimicrobial properties of a partially reduced dihydronathphthoquinone analogue of 2-methoxy, 5-acetoxy calamenene, extracted from Subergorgia reticulata. The growth of a pathogenic Vibrio ...
A revisit to the regulation of oxygen minimum zone in the Bay of Bengal
(Springer, 2020)
Occurrence of intense oxygen minimum zone (OMZ) is known in the Bay of Bengal (BoB), but it has been recently reported to have become more acute and is at its tipping point. Here, we show that the intensification of OMZ ...
Interannual changes of austral summer coccolithophore assemblages and southward expanse in the Southern Indian Ocean
(Elsevier Ltd, 2020)
Coccolithophore ecology and biogeography in the Southern Indian Ocean was studied during the austral summer of 2009 (SOE09; late austral summer), 2010 (SOE10; mid-austral summer), and 2012 (ISEA12; early austral summer). ...
Regional Study of Changes in Wind Power in the Indian Shelf Seas over the Last 40 Years
(MDPI AG, 2020)
Wind power variations at two heights (the surface level and turbine hub level) were investigated at 20 locations in the shelf seas of India using hourly fifth generation European Centre for Medium-Range Weather Forecasts ...
Recent contributions to the geochemistry and sedimentology of estuaries, mangroves, and mudbanks along the Indian coast: A status report
(Indian National Science Academy, 2020)
In the last four years, significant progress has been made in biogeochemical/ geochemical and sedimentological studies of the coastal sediments along the east and west coasts of India. The present review highlights the ...
