Dominant Biological Control Over Upwelling on pCO2 in Sea East of Sri Lanka
(John Wiley & Sons, 2018)
Upwelling enhances pCO2 levels due to injection of carbon-rich water to the surface despite the removal of carbon due to increase in primary production supported by enhanced nutrients. It is hypothesized that in the Bay ...
New to total primary production ratio (f-ratio) in the Bay of Bengal using isotopic composition of suspended particulate organic carbon and nitrogen
(Elsevier, 2018)
Variations in the content and isotopic compositions of carbon and nitrogen in the suspended particulate matter were analysed to identify sources of nutrients and compute f-ratios (ratio of new production to primary production) ...
High biological productivity in the central Arabian Sea during the summer monsoon driven by Ekman pumping and lateral advection
(Indian Academy of Sciences, 2001)
Open oceans are generally oligotrophic and support less biological production. Results from the central Arabian Sea show that it may be an exception to this. We provide the observational evidence of fairly high biological ...
Controlling factors of the oxygen balance in the Arabian Sea's OMZ
(European Geosciences Union, 2012)
The expansion of OMZs (oxygen minimum zones) due to climate change and their possible evolution and impacts on the ecosystems and the atmosphere are still debated, mostly because of the inability of global climate models ...
An evaluation of physical and biogeochemical processes regulating the oxygen minimum zone in the water column of the Bay of Bengal
(American Geophysical Union, 2002)
Monthly oxygen budgets for the intermediate waters (100-1000 m) of the Bay of Bengal were constructed based on Modular Ocean Model (MOM) and oxygen data. The model results reveal that the oxygen levels in the oxygen minimum ...
Distribution and sources of particulate organic matter in the Indian monsoonal estuaries during monsoon
(American Geophysical Union, 2014)
The distribution and sources of particulate organic carbon (POC) and nitrogen (PN) in 27 Indian estuaries were examined during the monsoon using the content and isotopic composition of carbon and nitrogen. Higher phytoplankton ...
Particle backscattering variability in the coastal waters of Bay of Bengal: A case study along off Kakinada and Yanam Regions
(IEEE, 2013)
The distribution and variability of particulate back scattering coefficient (b<sub>bp</sub>) in the Godavari basin are reported for the first time using in situ measurements. A coastal cruise was conducted in the coastal ...
Physical forcing of biological productivity in the northern Arabian Sea during the northeast monsoon
(Pergamon, 2001)
Time-series observations at a nominally fixed location in the northern Arabian Sea (21 degrees N, 64 degrees E) during the Northeast Monsoon (winter, February) of 1997 showed the prevalence of cold sea-surface temperatures ...
Carbon dioxide emissions from the tropical Dowleiswaram Reservoir on the Godavari River, Southeast of India
(Scientific Research Publishing, 2013)
Time-series observations were conducted in the Dowleiswaram dam reservoir that was constructed on the largest monsoonal river in India to understand the source of inorganic carbon, and fluxes to the atmosphere. The reservoir ...
Air-sea gas transfer in a shallow, flowing and coastal environment estimated by dissolved inorganic carbon and dissolved oxygen analyses
(The Oceanographic Society of Japan, 2010)
We estimated gas exchange rates in Kabira Reef at Ishigaki Island, southwest Japan, using a mass balance calculation with dual ‘biological’ tracers: dissolved inorganic carbon (DIC) and dissolved oxygen (DO). The nighttime ...
