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 ...
Phylogeny and genetic variation within population of Tachypleus gigas (M�ller, 1785)
(Current Science Association, IAS, 2017)
Isolated population of Indian horseshoe crabs, Tachy-pleus gigas plays an important role in the ecology of several marine organisms, and is being scrutinized for its abundance and morphology by many researchers. However, ...
Antioxidant responses in gills and digestive gland of oyster Crassostrea madrasensis (Preston) under lead exposure
(Elsevier, 2017)
Crassostrea are ecologically and economically important bivalves and provide a good livelihood for coastal regions of many countries, including India. This study aims at evaluating the response of the antioxidant defense ...
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 ...
A first look at factors affecting aragonite compensation depth in the eastern Arabian Sea
(Elsevier, 2017)
Water column measurements suggest shoaling of aragonite saturation depths (ASD) throughout the world oceans, due to increase in greenhouse gas concentration. Past records of aragonite saturation state under different ...
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. ...
Longshore sediment transport in the surf zone based on different formulae: A case study along the central west coast of India
(Springer, 2017)
Understanding longshore sediment transport (LST) is a prerequisite for designing an effective coastal zone management strategy. The present study estimates the LST along the central west coast of India based on four bulk ...
Impact of maintenance dredging on macrobenthic community structure of a tropical estuary
(Elsevier, 2017)
This paper demonstrates the impact of maintenance dredging activities on the macrobenthic community structure of a tropical monsoonal estuary (Cochin estuary), located in the southwest coast of India for three consecutive ...
