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) ...
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 ...
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 ...
Nitrogen fixation rates in the eastern Arabian Sea
(Elsevier, 2017)
The Arabian Sea experiences bloom of the diazotroph Trichodesmium during certain times of the year when optimal sea surface temperature and oligotrophic condition favour their growth. We measured nitrogen fixation rates ...
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) ...
A zona incognita surrounds the secondary nitrite maximum in open-ocean oxygen minimum zones
(Elsevier, 2017)
An analytic gap exists between the lower limit of detection of oxygen (O2) by conventional sensors (LOD, ~1 - 3�M O2) and the appearance of NO2- from NO3- reduction (~0.05�M O2), which signifies the secondary nitrite ...
Iron partitioning during LOHAFEX: Copepod grazing as a major driver for iron recycling in the Southern Ocean
(Elsevier, 2017)
The LOHAFEX iron fertilization experiment was conducted for 39days in the closed core of a cyclonic mesoscale eddy located along the Antarctic Polar Front in the Atlantic sector of the Southern Ocean. Mixed layer (ML) ...
Noctiluca and copepods grazing on the phytoplankton community in a nutrient-enriched coastal environment along the southwest coast of India
(Springer, 2017)
The relative grazing impact of Noctiluca scintillans (hereafter referred only Noctiluca) and copepods (Acrocalanus gracilis, Paracalanus parvus, Acartia danae and Oithona similis) on the phytoplankton community in an ...
