Sea state observation in island-sheltered nearshore zone based on in situ intermediate-water wave measurements and NCEP/CFSR wind data
(Springer, 2015)In this study, wind-seas, swells, and the coastal wind pattern are examined to interpret the temporal diversity of the sea state in the island-sheltered nearshore zone off Karwar on the west coast of India. The sea state ... -
Lead distribution in coastal and estuarine sediments around India
(Elsevier, 2015)This study describes the geochemical distribution of lead (Pb) and identifies the critical factors that significantly control Pb distribution and speciation in coastal and estuarine sediments around India by using published ... -
Impact of river discharge on the coastal water pH and pCO<sub>2</sub> levels during the Indian Ocean Dipole (IOD) years in the western Bay of Bengal
(Elsevier, 2015)Monthly variations in inorganic carbon components during January 2010–December 2011 in the coastal Bay of Bengal (BoB) were studied in relation to the variations in Godavari River (GR) discharge using ship board measurements, ... -
Inter-annual sea level variability in the southern South China Sea
(Elsevier, 2015)The South China Sea (SCS) is the largest marginal sea in the western Pacific Basin. Sea level anomalies (SLAs) in the southern South China Sea (SSCS) are assumed to be governed by various phenomena associated with the ... -
Indo-Arab trading posts along the Saurashtra coast, Gujarat India (Study based on underwater archaeological explorations)
(Swati Publications; Delhi; India, 2015) -
An appraisal of biological responses and network of environmental interactions in non-mining and mining impacted coastal waters
(Springer, 2015)The coastal waters of Goa and Ratnagiri lying on the West coast of India are influenced by terrestrial influx. However, Goa is influenced anthropogenically by iron-ore mining, while Ratnagiri is influenced by deposition ... -
Khalkattapatna port: The lost archaeological heritage of Odisha, east coast of India
(Current Science Association, 2015)The history of Odisha, lying on the east coast of India, is well documented from the Stone Age onwards. The evidences suggest that the ports of Odisha had contacts with the Arabs, Mediterranean countries and South Asia, ... -
Seasonal variations in abundance, biomass and grazing rates of microzooplankton in a tropical monsoonal estuary
(Springer, 2015)Seasonal abundance, composition and grazing rates of microzooplankton (20–200 µm) in the Zuari estuary were investigated to evaluate their importance in food web dynamics of a tropical monsoonal estuary. Average abundances ... -
A seismotectonic study of the 21 May 2014 Bay of Bengal intraplate earthquake: Evidence of onshore-offshore tectonic linkage and fracture zone reactivation in the northern Bay of Bengal
(Springer, 2015)The earthquake of 21 May 2014 (Mw 6.0) in the northern Bay of Bengal (BOB) highlights the importance of studies on intraplate earthquakes in the oceanic regime for understanding the stress state of the oceanic lithosphere. ... -
Mineral chemistry and alteration characteristics of spinel in serpentinised peridotites from the northern central Indian Ridge
(Geological Society of India, 2015)Serpentinites (frequently cross cut by gabbroic dikelet), collected from Northern Central Indian Ridge (NCIR), Indian Ocean, contain both Cr-rich (Group I) and Cr-poor (Group II) variety of spinel. Based on mineralogy they ... -
Variability in stratification and flushing times of the Gautami-Godavari estuary, India
(Indian Academy of Sciences, 2015)In order to examine the influence of forcing (river flow and tides) and anthropogenic activities (dredging and dam regulation) on stratification, a study was conducted over a period of 19 months (June 2008– December 2009) ... -
Seasonal variability of salinity and salt transport in the northern Indian Ocean
(American Meteorological Society, 2015)Analyses using a suite of observational datasets (Aquarius and Argo) and model simulations are carried out to examine the seasonal variability of salinity in the northern Indian Ocean (NIO). The model simulations include ... -
Observational evidence of mixed rossby gravity waves at the central equatorial Indian Ocean
(Springer, 2015)Six-hourly soundings (GPS sonde) were carried out at the central equatorial Indian Ocean (80º–83ºE) during 25th September–10th October 2011 under the CINDY2011 (Cooperative Indian Ocean Experiment on Intra-seasonal variability ... -
Complementary terrain/single beacon-based AUV navigation
(University of Porto, 2015)This paper describes work done towards the development of advanced geophysical-based navigation systems for autonomous underwater vehicles (AUVs). The specific problem that we tackle is that of combining terrain-aided ... -
Salinity response to seasonal runoff in a complex estuarine system (Cochin estuary, west coast of India)
(Coastal Education and Research Foundation, 2015)The hydrographic conditions in Cochin estuary are investigated using longitudinal measurements of salinity profiles during a 1-year period. The estuary transformed from salt wedge conditions during the wet season to a ... -
Biogeosciences connecting earth`s spheres from microscopic to global scales
(European Geosciences Union, 2015)Mineralogical and elemental analyses of 20 ferromanganese (FeMn)-coated pumice samples from the Central Indian Ocean Basin (CIOB) indicate that todorokite is the major mineral phase, whereas vernadite occurs only rarely. ... -
The tectonic stress field evolution of India since the Oligocene
(Elsevier, 2015)A multitude of observations suggest neotectonic deformation in and around India, but its causes and history are unknown. We use a 2 dimensional finite element model with heterogeneous elastic strengths in continental regions ... -
A tectonic model reconciling evidence for the collisions between India, Eurasia and intra-oceanic arcs of the central-eastern Tethys
(Elsevier, 2015)Despite several decades of investigations, inferences on the timing and nature of collisions along the Mesozoic–Cenozoic Eurasian margin remain controversial. We assimilate geological and geophysical evidence into a plate ... -
Trends in surface wind speed and significant wave height as revealed by ERA-Interim wind wave hindcast in the Central Bay of Bengal
