S- and Sr-isotopic compositions in barite-silica chimney from the Franklin Seamount, Woodlark Basin, Papua New Guinea: constraints on genesis and temporal variability of hydrothermal fluid
(Springer Berlin Heidelberg, 2017)
Isotopic ratios of strontium and sulfur in six layers across a horizontal section of a hydrothermal barite-silica chimney from Franklin Seamount of western Woodlark Basin have been investigated. Sr-isotopic ratios in barite ...
Global Carbon Cycling on a Heterogeneous Seafloor.
(Elsevier, 2018)
Diverse biological communities mediate the transformation, transport, and storage of elements fundamental to life on Earth, including carbon, nitrogen, and oxygen. However, global biogeochemical model outcomes can vary by ...
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 ...
Seasonal and Interannual Variability in the Barrier Layer of the Bay of Bengal
(Wiley, 2018)
An objectively analyzed monthly gridded ocean analysis derived from a combination of satellite and in situ observations is used to describe the seasonal and interannual variability in the barrier layer thickness (BLT) over ...
Slumping on the western continental margin of India
(Asociacion Argentina de Geofisicos y Geodestas, 2001)
A short gravity core from the Western Continental Margin of India has been examined to understand the nature and characteristics of slumping in the area. The present study and also the earlier studies revealed that the ...
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) ...
Mossbauer spectroscopy and x-ray diffraction studies of ferromanganese nodules from central Indian ocean basin
(Indian Society of Applied Geochemists, 2017)
We report room temperature 57Fe Mossbauer spectroscopic and powder X-ray diffraction studies carried out on Fe-Mn nodules collected from the Central Indian Ocean Basin, to understand the oxidation state of Iron. Mossbauer ...
Modulation of the Ganges-Brahmaputra River Plume by the Indian Ocean Dipole and Eddies Inferred From Satellite Observations
(Wiley, 2017)
The Bay of Bengal receives large amounts of freshwater from the Ganga?Brahmaputra (GB) river during the summer monsoon. The resulting upper?ocean freshening influences seasonal rainfall, cyclones, and biological productivity. ...
Statistical assessment to magnetic susceptibility and heavy metal data for characterizing the coastal sediment of East coast of Tamilnadu, India
(Pergamon, 2018)
A rapid urbanization and industrialization enhances the significant heavy metal pollution in the sediments of coastal area and introduced a serious threat to the human health. In the present study, concentration of heavy ...
