Isotopic composition of nitrate and particulate organic matter in a pristine dam reservoir of western India: Implications for biogeochemical processes
(European Geosciences Union, 2017)
Isotopic composition of nitrate (δ<sup>15</sup>N and δ<sup>18</sup>O) and particulate organic matter (POM; δ<sup>15</sup>N and δ<sup>13</sup>C) were measured in the Tillari Reservoir, located at the ...
Upwelling intensity modulates N2O concentrations over the western Indian shelf
(American Geophysical Union Publications, 2016)
Repeat measurements of dissolved nitrous oxide (N<sub>2</sub>O) along two transects of the western continental shelf of India in 2012 revealed high concentrations of 45±32 nM (off Kochi) and 73±63 nM (off Mangalore) during ...
Positive Indian ocean dipole events prevent anoxia off the west coast of India
(European Geosciences Union, 2017)
The seasonal upwelling along the west coast of India (WCI) brings nutrient-rich, oxygen-poor subsurface waters to the continental shelf, favoring very low oxygen concentrations in the surface waters during late boreal ...
Discriminating the biophysical impacts of coastal upwelling and mud banks along the southwest coast of India
(Elsevier, 2017)
Coastal upwelling and mud banks are two oceanographic processes concurrently operating along certain stretches of the southwest (Kerala) coast of India during the Southwest Monsoon period (June-September), facilitating ...
Anaerobic carbon mineralisation through sulphate reduction in the inner shelf sediments of eastern Arabian sea
(Springer, 2017)
Monsoon-induced coastal upwelling, land run-off, benthic and atmospheric inputs make the western Indian shelf waters biologically productive that is expected to lead to high rates of mineralisation of organic matter (OM) ...
Evolution to decay of upwelling and associated biogeochemistry over the southeastern Arabian sea shelf
(AGU Publications, 2016)
Observations along 10 shelf transects in 2012 near 10°N in the southeastern Arabian Sea revealed the usual warm oligotrophic conditions during the winter monsoon and upwelling of oxygen-deficient, nutrient-rich cool water ...
De-oxygenation
(ICSU-IAPSO-IUGG-SCOR, Paris, 2016)
N2 production rates limited by nitrite availability in the Bay of Bengal oxygen minimum zone
(Macmillan Publishers Limited, 2017)
A third or more of the fixed nitrogen lost from the oceans as N<sub>2</sub> is removed by anaerobic microbial processes in open ocean oxygen minimum zones. These zones have expanded over the past decades, and further ...
Suspended matter and fluid mud off Alleppey, southwest coast of India
(Elsevier, 2017)
Time series measurements on suspended particulate matter (SPM) were made at one non-mud bank (M1) and two mud bank stations (M2 and M3) off Alleppey, south west coast of India. The mean SPM was low in surface (6.2 mg/l) ...
