Insects of terrestrial origin over Indian Ocean during north-east monsoon
(Society of Biosciences, India, 2003)Airborne insects, carried by winds were trapped over the Indian Ocean (Latitude 14 degrees N to 4 degrees S; Longitude 60 degrees-76 degrees 34 minutes E), in the course of cruise 109, ORV Sagar Kanya (January 4-February ... -
Productivity fluctuations in the southeastern Arabian Sea during the last 140 ka
(Elsevier, 2003)Detailed analyses of multiple geochemical productivity proxies such as calcium carbonate, biogenic opal, biogenic Ba, organic carbon and total nitrogen have been carried out on a sediment core from the southeastern Arabian ... -
Landform changes from remote sensing data
(Tata Energy Research Institute, India, 2003)Coastal tourism is typically accompanied by developments along the coast - on sand dunes, cliffs, promontories, and sandy beaches - with possible implications for coastal processes and, eventually, for human activity located ... -
Evaluation of impact of PAH on a tropical fish, Oreochromis mossambicus using multiple biomarkers
(Elsevier, 2003)Treatment of the widely occurring tropical cichlid, Oreochromis mossambicus with a pure polycyclic aromatic hydrocarbon (PAH), phenanthrene, induced a concentration-dependant formation of the enzyme, 7-ethoxyresorufin-O-deethylase ... -
Arsenic enrichment in estuarine sediments-impact of iron and manganese mining
(BUET, Bangladesh, 2003)River Mandovi and Zuari, Goa (west coast of India) are flowing through iron and manganese mining areas and are heavily used for iron and manganese ore transport. This region generates 25-30 million tons of mining rejects ... -
The Arabian Sea
(Blackwell, 2003)The Arabian Sea makes contributions to global biogeochemical cycles that are far in excess of what might be expected from its modest size. It experiences extremes in atmospheric forcing, asymmetrically distributed over the ... -
Wet deposition of air pollution at southwest monsoon outbreak and its impact on groundwater resources of Greater Kochi region
(A.A. Balkema, 2003)The replenishable groundwater resources from natural recharge for Greater Kochi Region (GKR) is of low quantity and it suffer from salinity intrusion, with the level of ground water development at 21.02%. The wet deposition ... -
Geochemistry of surficial sediments along the central southwest coast of India - Seasonal changes in regional distribution
(Coastal Education and Reserch Foundation, 2003)The coastal sediments (129 samples) of central- southwest coast of India, in and around Cochin, the second biggest industrial city along the west coast of India, were analyzed for their textural and geochemical fractions ... -
Carbon budget in the eastern and central Arabian Sea: An Indian JGOFS synthesis
(American Geophysical Union, 2003)The carbon budget for the eastern and central Arabian Sea was constructed using results from the Modular Ocean Model and biogeochemical data collected largely under the Indian Joint Global Ocean Flux Study programme. The ... -
Monitoring effects of simulated disturbance at INDEX site: Current status and future activities
(International Society of Offshore and Polar Engineers, 2003)During the Indian Deep-Sea Environment Experiment (INDEX), greater than 6000 cu.m of sediment was resuspended 5 m above seafloor. Data collected from deep-towed photography, sediment traps, sediment coring and CTD operations ... -
Position fixing and surveying techniques for marine archaeological studies
(National Institute of Oceanography, India, 2003)This technical report comprises of two major aspects: (1) Surface positioning and (2) Sub-surface Positioning, which are followed for obtaining geographical positions while carrying out marine archaeological studies. Also, ... -
Trace metal levels in nearshore sediments close to industrial discharges off Cuddalore (Bay of Bengal)
(ASTM International, 2003)Trace metals in the sediment and in the overlying water column along with texture characteristics in the vicinity of industrial discharges at Cuddallore were analyzed, covering the seasonal changes to identify probable ... -
Multipeakedness and groupiness of shallow water waves along Indian coast
(Coastal Education and Reserch Foundation, 2003)Based on one year wave data collected at 4 locations along the Indian coast, the frequency of occurrence of double-peaked spectra was estimated. It was found that 40% of the data analysed was single-peaked. The double ... -
Orbital frequencies in radiolarian assemblages of the central Indian Ocean: implications on the Indian summer monsoon
(Elsevier, 2003)Radiolarian distribution in surface sediments and its relationships with overlying surface oceanography provided impetus for down-core faunal variation related to changes in monsoon intensity due to the Earth's orbital ... -
Environmental studies for deep seabed mining
(Discovery Publishing House, 2003)Minerals from the deep-sea are potential sources of metals such as Cu, Ni, Co, Mn, Fe, that could be mined in future by developing suitable technologies for mining as well as extracting metals from them. Several groups of ... -
Potential impact on climate of the exploitation of methane hydrate deposits offshore
(Elsevier, 2003)Considerable attention has focussed on methane hydrates as a potential energy resource but much less on the potential environmental problems of exploiting these deposits. In fact, methane hydrate deposits represent a dynamic ... -
Methane hydrate in marine sediments: New alternative for natural energy
(National Institute of Oceanography, India, 2003) -
Geochemistry of ferromanganese micronodules and associated Mn and trace metals diagenesis at high terrigenous depositional site of middle fan region, Bay of Bengal
(Elsevier, 2003)The influence of sedimentation on the morphology, growth and geochemistry of the micronodules, and on Mn enrichment in the sediments of the Bay of Bengal has been evaluated. Mn accumulation is 307-219 mg cm u2 kyr u-1 in ... -
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ... -
Microbial dolomite crusts from the carbonate platform off western India
(International Association of Sedimentologists, 2003)The occurrence of Late Pleistocene dolomite crusts that occur at 64 m depth on the carbonate platform off western India is documented. Dolomite is the most predominant mineral in the crusts. In thin section, the crust ...
