Iron organic speciation during the LOHAFEX experiment: Iron ligands release under biomass control by copepod grazing
(Elsevier B.V., 2020)
The LOHAFEX iron fertilization experiment consisted in the fertilization of the closed core of a cyclonic eddy located south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean. This eddy was characterized ...
Biogeochemistry of methane in a tropical monsoonal estuarine system along the west coast of India
Estuaries are known to be important sources of methane (CH4) to the atmosphere. However, a lack of adequate field studies in understanding the sources/sinks of CH4 in estuaries hampers the global atmospheric budgeting. ...
Ecological diversity of planktonic protists in spatial regimes of the Arabian Sea revealed through next-generation sequencing
Eukaryotic microbes inhabiting diverse ecological niches are capable of mediating biogeochemical shifts. Here, we studied the distribution patterns of protistan community in oxygen-deficient sites in the Arabian Sea and ...
Massive Methane Loss During Seasonal Hypoxia/Anoxia in the Nearshore Waters of Southeastern Arabian Sea
(Frontiers Media S.A., 2020)
Repeat observations over the Kochi and Mangalore shelves of the southeastern Arabian Sea (SEAS) during April to December 2012 revealed substantial accumulation of methane (CH4) in the nearshore waters (48.6 � 34.4 nM) ...
Multidisciplinary Observing in the World Ocean�s Oxygen Minimum Zone Regions: From Climate to Fish - The VOICE Initiative
Multidisciplinary ocean observing activities provide critical ocean information to satisfy ever-changing socioeconomic needs and require coordinated implementation. The upper oxycline (transition between high and low oxygen ...
Variability of frontal structure in the south Indian/Antarctic Ocean: Possible reason for longitudinal differences in the intensity of the oxygen maximum
(Goa: National Inst of Oceanography, 1987)
Coral reef ecosystems
(Oxford & IBH, New Delhi, 1994)
A zona incognita surrounds the secondary nitrite maximum in open-ocean oxygen minimum zones
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
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) ...
Discriminating the biophysical impacts of coastal upwelling and mud banks along the southwest coast of India
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 ...
