Understanding our seas: National Institute of Oceanography, Goa
(Current Science Association, 2015)
The present article summarizes the research done at the CSIR–National Institute of Oceanography in 2014 in ocean science, resources and technology. Significant research has been conducted on air–sea interactions and coastal ...
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 ...
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 ...
Mud banks of Kerala: Mystery yet to be unveiled!
(CSIR-NISCAIR, 2016)
Mud Banks are areas of the sea adjoining the coast with calm water during the roughest monsoon conditions of the sea. They provide a rich catch of fishery too.
Storm and tsunami induced sediment transport and morphology changes in vicinity of tidal inlets
(Indian Institute of Technology, Madras, 2014)
This study comprises of numerical modelling studies on the morphology changes in the vicinity of tidal inlets. Two real case scenarios comprising of a very severe cyclonic storm and the mega Indian Ocean tsunami were ...
Range-based underwater vehicle localization in the presence of unknown ocean currents: Theory and experiments
(IEEE, 2016)
This paper addresses the problem of range-based autonomous underwater vehicle (AUV) localization in the presence of unknown ocean currents. In the setup adopted, the AUV is equipped with an attitude and heading reference ...
Indian Ocean dipole modulated wave climate of eastern Arabian Sea
(European Geosciences Union, 2016)
Intrinsic modes of variability have a significant role in driving the climatic oscillations in the oceanic processes. In this paper, we investigate the influence of an inter-annual mode of variability, the Indian Ocean ...
Why is the Bay of Bengal experiencing a reduced rate of sea surface warming?
(Royal Meteorological Society, 2016)
The sea surface temperature (SST) in the Bay of Bengal (BoB) during the period 1960–1995 showed a decadal cycle, riding over a warming trend. The disruption of the decadal cycle was noticed post-1995 and was followed by a ...
Absolute calibration of SARAL/AltiKa in Kavaratti during its initial calibration-validation phase
(Taylor and Francis, 2015)
The Kavaratti calibration-validation site in India at Lakshadweep Sea has been improved to carry out absolute calibration of SARAL/AltiKa altimeter. This site is augmented with a down-looking radar gauge and a permanent ...
Mineralogy and Sr–Nd isotopes of SPM and sediment from the Mandovi and Zuari estuaries: Influence of weathering and anthropogenic contribution
(Elsevier, 2015)
Clay minerals and Sr–Nd isotopes of suspended particulate matter (SPM) and bottom sediment were investigated along transect stations of the Mandovi and Zuari estuaries, western India to determine the provenance and role ...
