Macrobenthic abundance in the vicinity of spreading ridge environment in Central Indian Ocean
(Indian Academy of Sciences, 2003)Macrofaunal communities of the Central Indian Ocean were evaluated for their composition, distribution, abundance and biomass. The fauna comprised of 24 major groups belonging to 15 phyla. The density of macrofauna varied ... -
Manganese nodules as a possible source of precious metals
(Indian Academy of Sciences, 2004)Marine geochemistry of Platinum (Pt) and Iridium (Ir) shows that both the elements are relatively enriched in manganese nodules. Compared to Pt concentration in the earth's upper continental crust the oceanic manganese ... -
Megafaunal community structure of Andaman seamounts including the back-arc basin - A quantitative exploration from the Indian Ocean
(Public Library of Science, 2011)Species rich benthic communities have been reported from some seamounts, predominantly from the Atlantic and Pacific Oceans, but the fauna and habitats on Indian Ocean seamounts are still poorly known. This study focuses ... -
Micrometer- and nanometer-sized platinum group nuggets in micrometeorites from deep-sea sediments of the Indian Ocean
(The Meteoritical Society, 2011)We examined 378 micrometeorites collected from deep-sea sediments of the Indian Ocean of which 175, 180, and 23 are I-type, S-type, and G-type, respectively. Of the 175 I-type spherules, 13 contained platinum group element ... -
Minima of interannual sea-level variability in the Indian Ocean
(Elsevier, 2010)Wavelet analysis of altimeter sea level in the Indian Ocean shows regions of high variability (maxima) and low variability (minima) at all time scales. At interannual time scales, i.e., at periods of 17 months or more, ... -
Mismo field experiment in the equatorial Indian Ocean
(American Meteorological Society, 2008)The Mirai Indian Ocean cruise for the Study of the Madden–Julian oscillation (MJO)-convection Onset (MISMO) was a field experiment that took place in the central equatorial Indian Ocean during October-December 2006, using ... -
Modeling the barrier-layer formation in the South-Eastern Arabian Sea
(American Meteorological Society, 2007)The effect of salinity on the formation of the barrier layer (BL) in the South-Eastern Arabian Sea (SEAS) is investigated using an ocean general circulation model. In accordance with previous studies, the runoff distribution ... -
Monograph On Bothid Larvae (Pleuronectiformes - Pisces)
(Regional Centre, National Institute of Oceanography, Cochin, 2004)The scarcity of larval material in the IIOE collections, the faulty preservation which led to the mutilation and dismembering of parts of the specimens as well as nonavailability of connecting links between various stages ... -
Monsoonal and ENSO impacts on particle fluxes and the biological pump in the Indian Ocean
(American Geophysical Union, 2009)Data obtained by sediment trap experiments in the Indian Ocean were evaluated in conjunction with additional information derived mainly from the Joint Global Ocean Flux Study (JGOFS) expeditions in 1994/1995. Our results ... -
Monsoonal reversal of remote sensing biases in latent heat flux over eastern Arabian Sea
(American Geophysical Union, 2006)The Arabian Sea is a unique basin where a number of atmospheric and oceanographic processes occur due to the contrasting climatic conditions, which it experiences. The drastic monsoonal variability occurring in the boundary ... -
Morphology and physiology of the marine straminipilan fungi, the aplanochytrids isolated from the equatorial Indian Ocean
(NISCAIR, CSIR, 2006)While thraustochytrids, a group of unicellular marine straminipilan protists, have been found to be abundant in the water column, little is known of aplanochytrids. These constitute one of the 3 groups belonging to the ... -
Net community production in the northern Indian Ocean
(American Geophysical Union, 2009)The monthly/seasonal variability in net community production (NCP) is controlled by the monsoon either through increasing nutrients to the euphotic zone or an increase in river runoff in the northern Indian Ocean. Net ... -
New records of Thecacineta cothurnioides and Trematosoma rotunda (Ciliophora, Suctorea) as epibionts on nematodes from the Indian Ocean
(Not clear, 2009)This article deals with the report of two suctorian ciliates species viz. Thecacineta cothurnioides Collin, 1909 and Trematosoma rotunda (Allgen, 1952) as epibionts on Tricoma sp. and Pseudochromadora sp. (Nematoda) ... -
New stable isotope records of sediment cores from the SE Arabian Sea - Inferences on the variations in monsoon regime during the late Quaternery
(Indian Academy of Sciences, 2001)We reconstruct here the changes in regional hydrography related to the fluctuations in Indian monsoons during the late Quaternary based on the stable isotope composition of the foraminifers and organic matter in three ... -
Observational evidence for westward propagation of temperature inversions in the southeastern Arabian Sea
(American Geophysical Union, 2004)A warm pool forms in the southeastern Arabian Sea (SEAS) prior to the onset of the summer monsoon over India in early June; the core of this warm pool is in the Lakshadweep Sea (LS). XBT and surface salinity data collected ... -
Occurrence of soft sediment deformation at Dive Agar beach, west coast of India: possible record of the Indian Ocean tsunami (2004)
(Springer, 2011)Authors describe here a sequence of soft sediment deformation (SSD) structures at Dive Agar beach near Srivardhan in the west coast of India. The approx.120-cm-thick sediment package is represented by a basal undeformed ... -
Ocean-atmosphere interactions during cyclone Nargis
(American Geophysical Union, 2009)Cyclone Nargis (Figure 1a) made landfall in Myanmar (formerly Burma) on 2 May 2008 with sustained winds of approximately 210 kilometers per hour, equivalent to a category 3-4 hurricane. In addition, Nargis brought approximately ... -
Oceanic fronts along 45 degrees across Antarctic Circumpolar Current during austral summer 2004
(Indian Academy of Sciences, 2005)A pilot expedition was launched to monitor the oceanic fronts in the southwestern sector of the Indian Ocean during January–February 2004. Major fronts along 45 degrees E between 40 and 56 degrees S were delineated and ... -
On the diurnal ranges of sea surface temperature (SST) in the north Indian Ocean
