Ichthyofaunal diversity and ecology of intertidal rock pools of Goa, west coast of India
(Fishing Chimes, 2012)A total of 386 fish representing 9 species were collected from two rocky shores of Goa viz. Vainguinim and Anjuna beaches. Family Blenniidae constituted 80% of fishes which included three species of the Genus Istiblennies ... -
Abundance and size variation of Globorotalia menardii in the Northeastern Indian Ocean during the Late Quaternary
(Geological Society of India, 2012)Variation in absolute abundance, size and coiling direction ratio of the planktic foraminifera Globorotalia menardii during the late Quaternary have been studied in three cores, collected along a north-south transect from ... -
Influence of upper-ocean stratification on tropical cyclone-induced surface cooling in the Bay of Bengal
(American Geophysical Union, 2012)Surface cooling induced by tropical cyclones (TCs) is about three times larger during premonsoon than during postmonsoon season in the Bay of Bengal. We investigate processes responsible for this seasonal contrast using ... -
Microbial community response during the iron fertilization experiment LOHAFEX
(American Society for Microbiology, 2012)Iron fertilization experiments in high nutrient-low chlorophyll areas are known to induce phytoplankton blooms. However, little is known about the response of the microbial community upon iron fertilization. As part of the ... -
Controlling factors of the oxygen balance in the Arabian Sea's OMZ
(European Geosciences Union, 2012)The expansion of OMZs (oxygen minimum zones) due to climate change and their possible evolution and impacts on the ecosystems and the atmosphere are still debated, mostly because of the inability of global climate models ... -
Identification of mangroves and coral reefs in the southern Gulf of Kachchh using principal component analysis and geo-spatial techniques: A case study
(ESRI India, 2012)The major objectives of this study were to extract the coral reef zones and mangroves using IRS P6 LISS IV data by employing the most appropriate technique, suited for the particular feature. Firstly, a few sample locations ... -
Preface: Special Issue of the 5th International Symposium on Biological and Environmental Chemistry of DMS(P) and Related Compounds, Goa, India, 19–22 October 2010
(Springer, 2012)This Special Issue of Biogeochemistry contains a selection of papers presented at the 5th International Symposium on Biological and Environmental Chemistry of DMS(P) and Related Compounds, organized at the National Institute ... -
Yttrium and rare earth element contents in seamount cobalt crusts in the Indian Ocean
(Current Science Association, 2012)Cobalt-rich Fe-Mn crusts occur on almost all seamounts and plateaus of the world oceans. Fe-Mn crusts are formed through layer-by-layer accretion of colloidal precipitates from cold ambient seawater onto exposed seamount ... -
Imtechella halotolerans gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from estuarine water
(International Union of Microbiological Societies, 2012)A novel Gram-negative, rod-shaped, non-motile, non-sporulating bacterium, designated strain K1 sup(T), was isolated from an estuarine water sample collected from Kochi, Kerala, India. Colonies on marine agar were circular, ... -
Isolation and characterization of antibacterial compound from a mangrove-endophytic fungus, Penicillium chrysogenum MTCC 5108
(Association of Microbiologists of India, 2012)Microorganisms, especially endophytic fungi that reside in the tissue of living mangrove plants, seem to play a major role in meeting the general demand for new biologically active substances. During the course of screening ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari Basin: Full waveform inversion
(American Geophysical Union, 2012)In fine-grained, faulted sediments, both stratigraphic and fault-induced structural variations can simultaneously determine the gas hydrate distribution. Insights into hydrate distribution can be obtained from P wave ... -
Altimetric observations and model simulations of coastal Kelvin waves in the Bay of Bengal
(Taylor & Francis, 2012)Wavelet analyses of sea surface height (SSH) obtained from Simple Ocean Data Assimilation (SODA) reanalysis, satellite altimetry derived SSH anomalies during 1993–2006, and HYbrid Coordinate Ocean Model (HYCOM) simulations ... -
The 2005 volcano-tectonic earthquake swarm in the Andaman Sea: Triggered by the 2004 great Sumatra-Andaman earthquake
(American Geophysical Union, 2012)A 6 day duration earthquakes swarm occurred in the Andaman Sea, 31 days after the giant 2004 Sumatra-Andaman earthquake (Mw 9.2). The swarm occurred less than 100 km from the eastern edge of the 2004 earthquake rupture and ... -
Impact of tropical cyclones on the heat budget of the south Pacific Ocean
(American Meteorological Society, 2012)The integrated ocean response to tropical cyclones (TCs) in the South Pacific convergence zone through a complete ocean heat budget was investigated. The TC impact analysis is based on the comparison between two long-term ... -
Ganga-Brahmaputra river discharge from Jason-2 radar altimetry: An update to the long-term satellite-derived estimates of continental freshwater forcing flux into the Bay of Bengal
(American Geophysical Union, 2012)This paper discusses the use of Jason-2 radar altimeter measurements to estimate the Ganga-Brahmaputra surface freshwater flux into the Bay of Bengal for the period mid-2008 to December 2011. A previous estimate was generated ... -
Recent studies on wind seas and swells in the Indian Ocean
(IIT Bombay, 2012)Winds and waves measured at a few locations along the west coast of India were analysed to study the wave characteristics in the deep as well as near shore regions during different seasons. The potential generation of ... -
Modification of wind-wave model WAM and its verification against buoy data in the Indian Ocean
(IIT Bombay, 2012)An attempt is made to improve the accuracy of wave prediction in the Indian Ocean. For this purpose, two versions of the wave model WAM have been used: WAM (Cycle 4) and the new version of WAM, called NewWAM. The three ... -
A multi-sensor autonomous platform for fast ocean observation studies
(Indian National Centre for Ocean Information Services (INCOIS), 2012)A new platform Autonomous Vertical Profiler (AVP) has been developed at CSIR - National Institute of Oceanography in Goa, India that can rapidly and autonomously collect repetitive data to 200m water depth. It is equipped ... -
Seafloor roughness estimation employing bathymetric systems: An appraisal of the classification and characterization of high-frequency acoustic data
(American Institute of Physics, 2012)The study of the seafloor is important for living and non-living resource estimation along with the related processes identification. To understand the fine-scale seafloor processes, various methods such as application of ... -
