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. ...

Denitrification processes in the Arabian Sea
(Indian Academy of Sciences, Bangalore, 1994)
Recent information on some consequences of the acute mid-water oxygen deficiency in the Arabian Sea, especially on carbon-nitrogen cycling, is reviewed. An evaluation of published estimates of water column denitrification ...
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 ...
Influence of upwelling induced near shore hypoxia on the Alappuzha mud banks, South West Coast of India
The results of the first time-series measurements spanning 18-weeks (22 April to 20 September 2014) from a coastal environment (Alappuzha, southwest India), where two process of upwelling and mud banks are concurrent during ...
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)
