Decadal shoreline assessment using remote sensing along the central Odisha coast, India
(Springer, 2015)One of the major requirements of planning coastal protection works is to understand the processes of erosion, deposition, sediment transport, flooding and sea level changes which continuously alter the shoreline. Significant ... -
Deep sea drilling in the Arabian Sea: Constraining tectonic-monsoon interactions in South Asia (Report)
(International Ocean Discovery Program, 2015)The Indian (southwest) summer monsoon is one of the most intense climatic phenomena on Earth. Its long-term development has been linked to the growth of high topography in South and Central Asia. The Indian continental ... -
Detection of decadal shoreline changes along Dhamara and Maipura coast, Odisha, India
(IAHR-AIRH, 2014)Coastal erosion is one of the major problems of the coastal zone. The erosion is triggered by various reasons such as high wave energy, reduction of sediments, natural disasters and climate change etc. In the era of ... -
Directional characteristics of shallow water waves along southwestern Bay of Bengal
(Elsevier, 2016)The aim of the present research is to investigate the directional characteristics of waves along the southwestern Bay of Bengal based on the measured data during 2010 at 14 m water depth. Diurnal, monthly and annual variation ... -
Effect of wind turbine on TLP flating platform response
(eSAT Publishing House, Bangalore, India, 2015)Ever increasing population of India demands high production of electrical energy which puts immense pressure on our limited stock of non-renewable sources of energy and makes us dependent over imports from foreign countries. ... -
Environmental isotopes to test hypotheses for fluid mud (mud bank) generation mechanisms along the southwest coast of India
(Elsevier, 2015)Occurrence of fluid mud (mud banks) in the southwest coast of India is an enigma for the scientific community. Over the years, several multi-disciplinary studies were conducted and various hypotheses were postulated on the ... -

Estimating discharge from the Godavari river using ENVISAT, Jason-2, and SARAL/AltiKa radar altimeters
(Taylor & Francis, 2016)The present work discusses the application of radar altimeters on-board Environmental Satellite (ENVISAT), Jason-2, and Satellite with Argos and AltiKa (SARAL) missions to estimate the Godavari River discharge draining ... -
Estimation of air-sea CO2 flux in the coastal waters of Visakhapatnam
(Springer, 2015)Observations were conducted in a time series mode off Visakhapatnam in Bay of Bengal, for a period of 10 days from 8 to 19th February 2013 to examine the short-term atmospheric events on chemical processes in the upper 100 ... -
Estimation of sea surface temperature (SST) using marine seismic data
(Springer, 2016)Not much attention is given to direct wave arrivals in marine seismic data that are acquired for petroleum exploration and prospecting. These direct arrivals are usually muted out in routine seismic data processing. In the ... -
Evaluation of the influence of monsoon climatology on dispersal and sequestration of continental flux over the southeastern Arabian Sea
(Elsevier, 2016)Associated with the coupled land–ocean heating–cooling, seasonal reversal of monsoon winds regulates hydrography, precipitation, upwelling, fluvial influx and a host of biogeochemical processes. We evaluate the role of the ... -
Evolution and sub-surface characteristics of a sea-surface temperature filament and front in the northeastern Arabian Sea during November–December 2012
(Elsevier, 2015)We used satellite-derived sea-surface-temperature (SST) data along with in-situ data collected along a meridional transect between 18.85 and 20.25°N along 69.2°E to describe the evolution of an SST filament and front during ... -
Evolution of extreme high waters along the east coast of India and at the head of the Bay of Bengal
(Elsevier, 2016)The recent evolution of extreme high waters along the severe cyclone-risk coasts of the Bay of Bengal (the east coast of India and Bangladesh) was assessed using long-term (24–34 years) hourly tide gauge data available ... -
Fine scale analyses of a coralline bank mapped using multi-beam backscatter data
(NIOT, Chennai, 2015)In this work, we have developed a classification technique to characterize the seafloor of the Gaveshani (coralline) bank area using multi-beam backscatter data. Softcomputational techniques like the artificial neural ... -
Fluctuations of Mediterranean outflow water circulation in the Gulf of Cadiz during MIS 5 to 7: Evidence from benthic foraminiferal assemblage and stable isotope records
(Elsevier, 2015)We studied variations in benthic foraminiferal assemblages and δ<sup>13</sup>C for the last 225 kyr at IODP site U1387 which is currently bathed by upper core of the Mediterranean Outflow Water (MOW). The MOW paleocirculation ... -
Geospatial approach towards enumerative analysis of suspended sediment concentration for Ganges-Brahmaputra Bay
(Elsevier, 2016)This study presents an easy, modular, user-friendly, and flexible software package for processing of Landsat 7 ETM and Landsat 8 OLI-TIRS data for estimating suspended particulate matter concentrations in the coastal waters. ... -
How biological (fish) noise affects the performance of shallow water passive array system
(NIOT, Chennai, 2015)Passive acoustic data off Grand Island, Goa were acquired using a single wideband hydrophone system deployed at the water depth of ~20.5 m during the month of April, 2014. The 4- elements hydrophone array with an aperture ... -
Identifying the source of tar balls deposited along the beaches of Goa in 2013 and comparing with historical data collected along the west coast of India
(Elsevier, 2015)Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a ... -
