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 ...
A significant shift in particulate organic matter characteristics during flooding of River Krishna, eastern peninsular India
(Current Science Association, IAS, 2020)
Extremely heavy rainfall over a small, semi-arid section of the Indian Peninsula in October 2009, together with release of water from dams resulted in very severe flooding in River Krishna. The sources and type of organic ...
Spatial and temporal variability in concentration and characteristics of aerosols at Visakhapatnam (east) and Goa (west) coasts of India
(2020)
Knowledge on the variability in quantity and compositions of various size groups of aerosols is important to understand their sources and their role in biogeochemical and climate processes. Here, we studied total suspended ...
Book Review: Hot Carbon: Carbon-14 and a Revolution in Science
(Current Science Association, IAS, 2020)
A short review of the book titled �Hot Carbon: Carbon-14 and a Revolution in Science� authored by John F. Marra and publihsed by Columbia University Press, New York in 2019. The relevance and the description of the content ...
Potential mechanisms responsible for occurrence of core oxygen minimum zone in the north-eastern Arabian Sea
(Elsevier, 2020)
The thickness of oxygen minimum zone (OMZ) is estimated for the first time using dissolved oxygen (DO) profiles obtained from the Biogeochemical Argo floats collected between 2013 and 2019 in the Arabian Sea. The depth of ...
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 ...
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). ...
Severe phosphate limitation on nitrogen fixation in the Bay of Bengal
(Elsevier BV, 2020)
Several anticyclonic (ACE) and cyclonic (CE) eddies constitute the circulation in the Bay of Bengal (BoB) and are associated with the downwelling and upwelling processes leading to oligotrophic and eutrophic conditions ...
Sources of organic matter and tracing of nutrient pollution in the coastal Bay of Bengal
(Pergamon, 2020)
Stable isotopic composition of carbon (delta13CPOM) and nitrogen (delta15NPOM) in the particulate organic matter (POM) is used to identify sources of organic carbon and nutrients using monthly time-series observation in ...
