A Cenozoic record of the equatorial Pacific carbonate compensation depth
(Nature Publishing Group, 2012)
Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these ...
Speciation of Co, Ni and Cu in the coastal and estuarine sediments: Some fundamental characteristics
(Elsevier, 2012)
Kinetic and sequential extraction methods were used to investigate chemical speciation and distribution of Co, Ni, and Cu in the estuarine and coastal sediments collected from the central east coast of India. The kinetic ...
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 ...
DNA damage and oxidative stress in marine gastropod Morula granulata exposed to phenanthrene
(Springer, 2016)
DNA damage and oxidative stress in marine gastropod Morula granulata was measured after in vivo exposure to four different concentrations (10, 25, 50, and 100 mikrog/L) of phenanthrene. Comet assay was used for measurement ...
Influence of orographically enhanced SW monsoon flux on coastal processes along the SE Arabian Sea
(American Geophysical Union, 2011)
The Arabian Sea has an excess evaporation over precipitation regime. The southeast Arabian Sea is, however, anomalous because it has ~2800–4800 mm rainfall during the southwest monsoon (SWM). Despite a high rainfall, the ...
Indian Ocean Dipole and El Nino/Southern Oscillation impacts on regional chlorophyll anomalies in the Indian Ocean
(Copernicus Publications, 2013)
The Indian Ocean Dipole (IOD) and the El Niño/Southern Oscillation (ENSO) are independent climate modes, which frequently co-occur, driving significant interannual changes within the Indian Ocean. We use a four-decade ...
Distribution of mesopelagic micronekton in the Arabian Sea during the winter monsoon
(NISCAIR, CSIR, 2010)
Response of micronekton to oxygen minimum zones in the Arabian Sea (AS) during winter monsoon period was investigated using data of 52 trawls deployed during four winter cruises between 1998 and 2000. Twenty-nine species, ...
Can hydrocarbons in coastal sediments be related to terrestrial flux? A case study of Godavari river discharge (Bay of Bengal)
(Current Science Association, 2015)
A sediment core aged ~250 years and deposition rate of ~2.4 mm yr<sup>-1</sup> raised from the coastal region receiving inputs from the Godavari river was examined for n-alkanes The carbon preference index (CPI) of shortchain ...
Bacterial diversity and their adaptations in the shallow water hydrothermal vent at D. Joao de Castro Seamount (DJCS), Azores, Portugal
(Station Biologique de Roscoff, 2012)
Bacterial diversity investigations were made from the shallow vent of D joao de castro, Azores, Portugal and their adaptations to a nutrient rich environment was investigated from 2004 and 2005 cruise samples. Assesment ...
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 ...
