A study on inorganic carbon components in the Andaman Sea during the post monsoon season
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2001)Extensive data have been collected on the carbon dioxide system during the post monsoon season in the eastern Bay of Bengal and the Andaman Sea of the northeastern Indian Ocean. The vertical distribution of temperature and ... -
Alterations in geochemical associations in artificially disturbed deep-sea sediments
(Taylor and Francis, 2005)In view of the role of sediment geochemistry in regulating the benthic ecosystem, diagenetic remobilization of dissolved constituents, bottom water redox, and regeneration of benthic fluxes, surficial sediments in and ... -
An interactive end-user software application for a deep-sea photographic database
(Elsevier, 2005)A photographic database is created for cataloguing data from underwater deep-tow photographic surveys conducted in the Central Indian Ocean Basin. This includes digitizing, encoding and merging different types of data and ... -
Arabian Sea upwelling - A comparison between coastal and open ocean regions
(Current Science Association, Bangalore, India, 1996)The response of the eastern Arabian Sea to prevailing winds during an upwelling event, in the peak of southwest monsoon, was studied at both coastal and open ocean environment based on the data collected as a part of the ... -
Barotolerance of fungi isolated from deep-sea sediments of the Indian Ocean
(Inter-Research, 1998)Two species of filamentous fungi, Aspergillus ustus (Bain.) Thoms and Church and Graphium sp., were isolated from calcareous animal shells at depths of 860 m in the Arabian Sea and 965 m in the Bay of Bengal. Laboratory ... -
Buried nodules from the central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)The occurrence of buried nodules is rare compared to surface nodule abundance in the deep sea. Surface nodules are collected with freefall grab, vanveen /peterson grabs, dredges and sediment cores whereas buried nodules ... -
Corrosion of metals and alloys in the coastal and deep waters of the Arabian Sea and the Bay of Bengal
(NISCAIR, New Delhi, 1993)Corrosion rate of mild steel (MS), stainless steel (SS), copper, brass and cupro-nickel has been determinEd. by exposing metallic coupons in coastal and oceanic waters of the Arabian Sea and Bay of Bengal. Amongst the ... -
Deep ocean fluxes and their link to surface ocean processes and the biological pump
(Elsevier, 2005)Intense studies of upper and deep ocean processes were carried out in the Northwestern Indian Ocean (Arabian Sea) within the framework of JGOFS and related projects in order to improve our understanding of the marine carbon ... -
Deep-sea fungi
(ASM Press, 2008)The deep-sea environment, despite being rich in mineral nutrients and near-saturation levels of oxygen, because of its darkness is not conducive to photosynthesis, the process that sustains life on earth. If a liigh abundance ... -
Delta sup(14)C, sigma CO sub(2) salinity of the western Indian Ocean deep waters: Spatial and temporal variations
(American Geophysical Union, 1999)Indian Ocean Deep waters (IDW) show an increase in salinity and sigma CO sub(2) between 64 degrees S and 16 plus or minus 4 degrees N by 0.106-0.110 ppt and 82-104 mu M kg sup(-1) respectively with a corresponding decrease ... -
Distribution of deep-sea benthos in the proposed mining area of Central Indian Basin
(Taylor and Francis, 2000)During the first stage of the project work on the Indian Deep-Sea Environment Experiment (INDEX), the abundance and distribution of deep-sea benthos were surveyed in the Central Indian Basin for the collection of baseline ... -
Environment and deep-sea mining: A perspective
(Taylor and Francis, 2000)As the quest for deep-sea mineral resources is gaining momentum, environment and ocean mining have become important aspects of study. Because many of these deposits occur in international waters, the concern for environmental ... -
Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ... -
Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ... -
Increased particle flux to the deep ocean related to monsoons
(Nature Publishing Group, 1989)Monsoons cause seasonal reversals in the surface circulation of the northern Indian Ocean. In the Arabian Sea this results in the upwelling of nutrient-rich water along the coasts, making it one of the highly productive ... -
Marine fungal biotechnology: An ecological perspective
(Fungal Diversity Press, 2008)This paper reviews the potential of marine fungi in biotechnology. The unique physico-chemical properties of the marine environment are likely to have conferred marine fungi with special physiological adaptations that could ... -
Microbial biomass and organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin
(Taylor and Francis, 2001)In order to assess the impact of deep-sea mining on the in situ benthic life, the microbial standing stock and concentration of organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin in the Indian ... -
Preliminary geotechnical properties of deepsea sediments from the Central Indian Basin
(Int. Soc. of Offshore and Polar-Eng.(ISOPE), Colorado, USA, 1995)Geotechnical properties of the Plio-Pleistocene sediments from nodule bearing area in the Central Indian Basin have been studied to know shear strength and water content variation with depth. It reveals that surface sediments ... -
Real time wave measurements and wave hindcasting in deep waters
(CSIR-NISCAIR, 1994)Deep water waves off Karwar (lat. 14~'45.1'N, long. 73~'34.8'E) at 75 m water depth pertaining to peak monsoon period have been measured using a Datawell waverider buoy. Measured wave data show that the significant wave ... -
Response of meiofauna to immediate benthic disturbance in the Central Indian Ocean Basin
