Effects of bottom water dissolved oxygen variability on copper and lead fractionation in the sediments across the oxygen minimum zone, western continental margin of India
(Elsevier, 2016)
This study describes the effect of varying bottom-water oxygen concentration on geochemical fractionation (operational speciation) of Cu and Pb in the underneath sediments across the oxygen minimum zone (Arabian Sea) in ...
The tectonic origin of the Bay of Bengal and Bangladesh
(American Geophysical Union Publications, 2016)
We are able to decipher the tectonic evolution of the Bay of Bengal, a puzzle which has not been satisfactorily solved in the past, and we are also able to shed new light on origin of the buried 85°E Ridge. We do so by ...
Understanding heavy mineral dynamics using magnetic fingerprinting technique: A case study of North Maharashtra Coast, India
(Springer, 2017)
Environmental magnetic and grain size measurements were carried out on sand samples collected from nine sand pits along a 20-km coastal stretch of Arnala Beach, North Maharashtra, India. This study sets out to identify the ...
Pseudofaults and associated seamounts in the conjugate Arabian and Eastern Somali basins, NW Indian Ocean- New constraints from high-resolution satellite-derived gravity data
(Elsevier, 2016)
Marine gravity data derived from satellite altimeters are effective tools in mapping fine-scale tectonic features of the ocean basins such as pseudofaults, fracture zones and seamounts, particularly when the ocean basins ...
In situ oxygen isotope compositions in olivines of different types of cosmic spherules: An assessment of relationships to chondritic particles
(Elsevier, 2016)
Cosmic spherules collected from deep sea sediments of the Indian Ocean having different textures such as scoriaceous (4), relict-bearing (16), porphyritic (35) and barred olivine (2) were investigated for petrography, as ...
Effect of submarine canyons on tsunami heights, currents and run-up off the southeast coast of India
(Current Science Association, 2016)
Tsunami numerical model studies are mostly focused on inundation and run-up onto the coast. Fewer studies have been aimed at investigating role of submarine canyons on the tsunami heights, currents and run-up. The influence ...
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) ...
Seasonal distribution of phytoplankton and its association with physico-chemical parameters in coastal waters of Malvan, west coast of India
(Springer, 2017)
Malvan coast is one of the Marine Protected Area (MPA) of Maharashtra because of its rich coral reef and biodiversity. The study investigated on phytoplankton assemblage and their diversity with respect to physico-chemical ...
Development of environmental management plan for deep-sea mining
(Springer, 2017)
Deep-sea mining is currently at a stage when several mine sites have been identified, mining technologies are under development, processing technologies are being tested, studies for assessing potential environmental impacts ...
Observed salinity changes in the Alappuzha mud bank, southwest coast of India and its implication to hypothesis of mudbank formation
(Elsevier, 2017)
Alappuzha mud bank draws special attention among the twenty-mud bank locations reported along the Kerala coast by its remoteness from riverine sources. Among several hypotheses proposed for the formation of mud bank, the ...
