A note on chemical composition and origin of ferromanganese oxide coated and uncoated pumice samples from central Indian Ocean basin
(Geological Society of India, 2016)
Pumice are explosive volcanic product, occur as uncoated or coated with ferromanganese (Fe-Mn) oxide and resides in association with ferromanganese nodules on the seabed in Central Indian Ocean Basin (CIOB). The older Fe-Mn ...
Multiple ash layers in late Quaternary sediments from the Central Indian Basin
(Elsevier, 2016)
We have investigated three sediment cores collected from water depths > 5000 m along the transect 76°30`E in close proximity to a fracture zone in the Central Indian Basin (CIB). The cores yielded five volcanic horizons ...
Distribution, provenance and early diagenesis of major and trace metals in sediment cores from the Mandovi estuary, western India
(Elsevier, 2016)
Major elements and trace metals were analyzed in four sediment cores recovered along a transect in the Mandovi estuary for their distribution, provenance and early diagenesis. The sediments were clayey silts in cores from ...
Decadal shoreline assessment using remote sensing along the central Odisha coast, India
(Springer, 2015)
One of the major requirements of planning coastal protection works is to understand the processes of erosion, deposition, sediment transport, flooding and sea level changes which continuously alter the shoreline. Significant ...
Crustal accretion at a sedimented spreading center in the Andaman Sea
(Geological Society of America, 2016)
The magmatic, tectonic, and hydrothermal processes forming the oceanic crust along mid-ocean spreading centers are strongly modified at sedimented spreading centers but poorly understood owing to the lack of good crustal ...
Oxygen isotopic composition of relict olivine grains in cosmic spherules: Links to chondrules from carbonaceous chondrites
(Elsevier, 2015)
Most olivine relict grains in cosmic spherules selected for the present study are pristine and have not been disturbed during their atmospheric entry, thereby preserving their chemical, mineralogical and isotopic compositions. ...
Effect of heavy metals on the carbon and nitrogen ratio in Avicennia marina from polluted and unpolluted regions
(Elsevier, 2015)
The accumulation of heavy metals and its impact on the C/N ratio of Avicennia marina of the Patalganga and Amba estuaries were studied. Vadinar was selected as a relatively uncontaminated location for comparison. Cd was ...
Microbial and biochemical alterations due to storage of deep-sea sediments under ambient tropical conditions
(NISCAIR Publications, 2016)
Response of indigenous bacteria to incubation at normal pressure and tropical temperature (28 ± 2°C), were examined in four deep-sea sediments from polymetallic-nodule fields in Central Indian Basin (CIB). Sediments were ...
Environmental controls on the speciation and distribution of mercury in surface sediments of a tropical estuary, India
(Elsevier, 2015)
Distribution and speciation of mercury (Hg) in the sediments from a tropical estuary (Godavari estuary) was influenced by the changing physico-chemical parameters of the overlying water column. The sediments from the ...
Enhanced methane flux event and sediment dispersal pattern in the Krishna–Godavari offshore basin: Evidences from rock magnetic techniques
(Elsevier, 2014)
Detailed rock magnetic measurements such as susceptibility (X), susceptibility of anhysteric remanent magnetization (X<sub>ARM</sub>), saturation isothermal remanent magnetization (SIRM), soft-isothermal remanent magnetization ...
