On the sea surface temperature high in the Lakshadweep Sea before the onset of the southwest monsoon
(American Geophysical Union, 1999)The north Indian Ocean becomes the warmest area of the world oceans prior to the onset of southwest monsoon in June. During this period a zonal band of high sea surface temperature (SST), the ``thermal equator'' (TE), moves ... -
On the semi-diagnostic computation of climatological circulation in the western tropical Indian Ocean
(India Meteorological Department, 2000)The seasonal mean climatological circulation in the Indian Ocean north of 20°S and west of 80°E during the summer and winter has been investigated using a 3-dimensional, fully non-linear, semi-diagnostic circulation model. ... -
Oxygen deficiency in the North Indian Ocean
(Universidad de Concepción, 2006)The Indian Ocean contains one of the oceans' most pronounced oxygen minimum zone (OMZ), which anolalously, is the most intene in the northwestern sector (Arabian Sea). It also contains the majority of the area of oceanic ... -
Past 20,000-year history of Himalayan aridity: Evidence from oxygen isotope records in the Bay of Bengal
(Indian Academy of Sciences, 2003)Late Quaternary climate history of the Himalayas is inferred from sea surface salinity (SSS) changes determined from the oxygen isotope in planktonic foraminifers, in a turbidity-free, 14C-dated core from the Bay of Bengal. ... -
Periodic deformation of oceanic crust in the central Indian Ocean
(AGU, 1998)New seismic reflection profiles of ~~ 5370 km, running through the Ocean Drilling Program Leg 116 sites and Deep Sea Drilling Project Sites 215 and 218, were obtained to investigate the spatial extent, timing, and nature ... -
Physical properties of a sediment core from the Central Indian Basin
(Indian Geophysical Union, 1998)A box core of 7.5 m was collected from the Central Indian Basin for the purpose of geotechnical studies and depthwise variation of physical properties and clay mineralogy. Water content, Atterberg limits, specific gravity ... -
Platinum group elements and gold in ferromanganese crusts from Afanasiy-Nikitin seamount, equatorial Indian Ocean: Sources and fractionation
(Indian Academy of Sciences, 2007)The major element relationships in ferromanganese (Fe–Mn) crusts from Afanasiy–Nikitin seamount (ANS), eastern equatorial Indian Ocean, appear to be atypical. High positive correlations (r = 0.99) between Mn/Co and Fe/Co ... -
Post-Cretaceous intraplate volcanism in the Central Indian Ocean Basin
(Elsevier, 1998)Interplate volcanism in the Central Indian Ocean Basin (CIOB) has been of much interest, since this tectonicaly young and structurally complex basin holds signatures of at least one major plate reorganisation (at 65 ~c 5 ... -
Preface to: Marine micropaleontological studies from the northern Indian Ocean
(NISCAIR, CSIR, 2007)Indian Ocean is unique, being land-locked towards the northern margin, and experiences, highest reported oceanic productivity. It is also the locale for the most severe oxygen depleted waters in the coastal and intermediate ... -
Quantitative characteristics of the Indian Ocean seafloor relief using fractal dimension
(NISCAIR, CSIR, 2007)In this paper spectral technique has been applied for seafioor topographic data analyses from three seafioor provinces of the Indian Ocean. Study sites include West of the Andaman Island (WAT), Western Continental Margins ... -
RAMA: The Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (including supplement)
(American Meteorological Society, 2009)The Indian Ocean is unique among the three tropical ocean basins in that it is blocked at 25 degrees N by the Asian landmass. Seasonal heating and cooling of the land sets the stage for dramatic monsoon wind reversals, ... -
Relevance of bacterioplankton abundance and production in the oligotrophic equatorial Indian Ocean
(Springer, 2008)Bacterioplankton abundance and production, chlorophyll a (Chl a) concentrations and primary production (PP) were measured from the equatorial Indian Ocean (EIO) during northeast (NEM), southwest (SWM) and spring intermonsoon ... -
Remote forcing annihilates barrier layer in southeastern Arabian Sea
(American Geophysical Union, 2004)Time-series measurements of temperature and salinity profiles were made every two hours at 74 deg 30'E, 9 deg 13'N in the southeastern Arabian Sea (SEAS) during 22 March to 7 April and 23 May to 7 June 2003 as part of ... -
Report of epibiont Thecacineta calix (Ciliophora: Suctorea) on deep sea Desmodora (Nematoda) from the Andaman Sea, Indian Ocean
(Marine Biological Association of the United Kingdom, 2010)Suctorian epibionts Thecacineta calix attached on the cuticle of nematodes Desmodora sphaerica and D. pontica are reported here from the deep sea hexactinellid sponge Pheronema sp. from the Andaman Sea (Indian Ocean). The ... -
Research opportunities and challenges in the Indian Ocean
(American Geophysical Union, 2008)The Indian Ocean is a dynamically complex and highly variable system, with circulation features and biogeochemical properties that are unusual in many respects. Yet the Indian Ocean (IO) remains one of the most under-sampled ... -
Resolving orographic rainfall on the Indian west coast
(Royal Meteorological Society, 2008)We discuss a method to obtain the spatial estimates of rainfall on the Indian west coast for calculating the surface water budget. The region includes the basin of the Mandovi River, a typical west-coast river whose catchment ... -
Response of deep-sea macrobenthos to a small-scale environmental disturbance
(Elsevier, 2001)To assess the possible effect of nodule mining on deep-sea environment, the Indian deep-sea environment experiment (INDEX) was undertaken in the Indian Basin. The present investigation is a part of the disturbance and ... -
Response of west Indian coastal regions and Kavaratti lagoon to the November-2009 tropical cyclone Phyan
(Springer, 2011)Response of the coastal regions of eastern Arabian Sea (AS) and Kavaratti Island lagoon in the AS to the tropical cyclonic storm `Phyan’, which developed in winter in the south-eastern AS and swept northward along the ... -
Role of eddies in the Bay of Bengal circulation and hydrography and in the distribution of nutrients and chlorophyll
(2007)Eddies are ubiquitous in the ocean and are products of geophysical turbulence. They develop from the hydrodynamic instabilities and are known to alter the physical and biochemical properties of the ocean. In the north ... -
