An evaluation of physical and biogeochemical processes regulating perennial suboxic conditions in the water column of the Arabian Sea
(American Geophysical Union, 2002)
Monthly oxygen budgets for the subsurface Arabian Sea (100-1000 m) are constructed on the basis of Modular Ocean Model and recently collected oxygen data. The model results are in agreement with the observed pattern. The ...
Silicon cycle in Indian estuaries and its control by biogeochemical and anthropogenic processes
(Elsevier, 2017)
We study the silicon biogeochemical cycle and its associated parameters in 24 and 18 Indian estuaries during dry and wet periods respectively. We focus more specifically on dissolved Si (DSi), amorphous Si (ASi,) lithogenic ...
Model simulation of tide-induced currents in Gauthami-Godavari estuary
(Current Science Association, 2013)
Predictive spatial distribution of flow field has been simulated from the time series data on currents and tides during dry season (11-19, February, 2009) in the Gauthami-Godavari Estuary utilizing TIDAL model. A 2D-Tidal ...
Tidally-modulated high frequency internal waves in Gautami-Godavari estuary, East coast of India
(CSIR-NISCAIR, 2014)
Time series temperature and salinity (at 1 hour interval) and currents data (10 min interval) at surface (3 m) and bottom (14 m), collected in the Gautami-Godavari estuary during 25-27 September 2008 were utilized to ...
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 ...
