Geotechnical properties of siliceous sediments from the Central Indian Basin
(Indian Academy of Sciences, 2002)Indian Deep-Sea Environment Experiment (INDEX) was carried out in a pre-selected area with low nodule abundance and uniform sediment type, for the purpose of environmental impact assessment of future deep-sea mining ... -
High CO2 emissions from the tropical Godavari estuary (India) associated with monsoon river discharges
(American Geophysical Union, 2011)Estuaries have been under sampled to establish them as sources or sinks of the atmospheric carbon dioxide. Such poor coverage is well known for tropical, particularly monsoon driven, estuaries. In an attempt to study the ... -
Impact of global warming on cyclonic storms over north Indian Ocean
(NISCAIR, CSIR, 2010)The impact of global warming on the cyclonic storms over the north Indian Ocean have been studied using a suite of multiple datasets that includes the NCEP/NCAR Reanalysis, the extended reconstruction sea surface temperature ... -
Improved bathymetric datasets for the shallow water regions in the Indian Ocean
(Indian Academy of Sciences, 2007)Ocean modellers use bathymetric datasets like ETOPO5 and ETOPO2 to represent the ocean bottom topography. The former dataset is based on digitization of depth contours greater than 200 m, and the latter is based on satellite ... -
Incorporation of transition and platinum group elements (PGE) in Co-rich Mn crusts at Afanasiy-Nikitin Seamount (AFS) in the equatorial S Indian Ocean
(The Society of Resource Geology, 2010)Of the 12 elements enriched in Co-rich Mn crusts from the Afanasiy-Nikitin Seamount in the Equatorial S Indian Ocean, Mn, Fe and Co are enriched by a factor of approx. 10 sup(9) compared to their concentrations in seawater ... -
India and the common heritage concept in the international seabed area
(Indian Academy of Sciences, 2004)The final relinquishment of 20% of the 150,000 km sup(2) under the 20 + 10 + 20% surrender arrangement has fulfilled India’s obligation towards implementing the common heritage of mankind (CHM) concept in the international ... -
Indian Ocean margins
(Springer-Verlag, 2010)The most important biogeochemical transformations and boundary exchanges in the Indian Ocean seem to occur in the northern region, where the processes originating at the land-ocean boundary extend far beyond the continental ... -
Indian Ocean research: Opportunities and challenges
(American Geophysical Union, 2009)Historically, the Indian Ocean (IO) has received relatively little attention from the oceanographic community and therefore remains substantially undersampled compared to the Atlantic and Pacific oceans. This situation is ... -
Indobis and its relevance to the Gulf of Mannar Biosphere reserve
(National Biodiversity Authority, 2008)The Gulf of Mannar (GoM) which has been given the status of a Biosphere Reserve in 1989 under the Man and Biosphere Reserve Programme of UNESCO. It was declared as the first marine protected area in South and South east ... -
IndOBIS, an Ocean Biogeographic Information System for assessment and conservation of Indian Ocean biodiversity
(NISCAIR, CSIR, 2005)Compilation of inventories of components of coastal and marine biodiversity of Indian Ocean is hampered by several factors: low effort by some countries, preference to certain taxon, dwindling taxonomic expertise, low ... -
Influence of environmental settings on the prevalence of Trichodesmium spp. in the Bay of Bengal
(Inter Research, 2008)Trichodesmium, an important marine nitrogen-fixing cyanobacteria, is widespread in tropical waters and contributes substantially to the global chemical cycles by new production. The interesting and intriguing feature of ... -
Integrated geophysical studies over the 85°E ridge - Evaluation and interpretation
(AP Akademi of Sciences, India, 2000)Ship-borne magnetic, gravity, bathymetry and multichannel seismic reflection studies made so far on the linear subsurface ridge known as the 85°E Ridge in the northeastern Indian Ocean are reviewed. The extent and boundaries ... -
Inter-relationship between nuclei and gross characteristics of manganese nodules, Central Indian Ocean Basin
(Taylor & Francis, 2008)More than 200 samples of manganese nodules from the Central Indian Ocean Basin (CIOB) were studied for their different parameters. The study included various aspects such as morphology, texture, mineralogy, and composition ... -
Interannual variability of Kelvin wave propagation in the wave guides of the equatorial Indian Ocean, the coastal Bay of Bengal and the southeastern Arabian Sea during 1993-2006
(Elsevier, 2010)The observed variability of the Kelvin waves and their propagation in the equatorial wave guide of the Indian Ocean and in the coastal wave guides of the Bay of Bengal (BoB) and the southeastern Arabian Sea (AS) on seasonal ... -
Intraseasonal meridional current variability in the eastern equatorial Indian Ocean
(American Geophysical Union, 2008)Intraseasonal variability in meridional current in the eastern equatorial Indian Ocean is investigated by use of results from a high-resolution ocean general circulation model. Both the simulated and observed meridional ... -
Intraseasonal response of the northern Indian Ocean coastal waveguide to the Madden-Julian Oscillation
(American Geophysical Union, 2009)A new observational record of upper-ocean currents at 15 degrees N on the western coast of India is dominated by intraseasonal (55-110 day) variations of alongshore currents, whereas sea level at the same location has a ... -
Introduction to Indian Ocean biogeochemical processes and ecological variability: Current understanding and emerging perspectives
(American Geophysical Union, 2009)Despite a history of exploration dating back to the classical era and its leading role as a pathway for trade and cultural exchange for the great civilizations of those times, the Indian Ocean has consistently been subject ... -
Late quaternary fluctuations in carbonate and carbonate ion content in the northern Indian ocean
(2008)The proposed research is aimed to understand the Late Quaternary fluctuations in carbonate and carbonate ion content in the northern Indian Ocean with the following specific objectives: 1) To identify suitable paleocarbonate ... -
Link between convection and meridional gradient of sea surface temperature in the Bay of Bengal
(Indian Academy of Sciences, 2007)We use daily satellite estimates of sea surface temperature (SST) and rainfall during 1998-2005 to show that onset of convection over the central Bay of Bengal (88-92E, 14-18N) during the core summer monsoon (mid-May to ... -
Low-frequency variability of sea level along the coast of India
(1998)Coastal sea level is one of the better documented oceanic variables, there being several tide-gauge records of hourly sea level that stretch back to the last century. This, together with the fact that geostrophic, low-frequency ...
