A simple estimation of equatorial Pacific response from windstress to untangle Indian Ocean dipole and basin influences on El Nino
Sea Surface Temperature (SST) anomalies that develop in spring in the central Pacific are crucial to the El Nino Southern Oscillation (ENSO) development. Here we use a linear, continuously stratified, ocean model, and its ...
The NOW regional coupled model: Application to the tropical Indian Ocean climate and tropical cyclone activity
(American Geophysical Union, 2014)
This paper presents the NOW regional coupled ocean-atmosphere model built from the NEMO ocean and WRF atmospheric numerical models. This model is applied to the tropical Indian Ocean, with the oceanic and atmospheric ...
Comparison of long-term variability of sea surface temperature in the Arabian Sea and Bay of Bengal
Long-term variability of Sea Surface Temperature (SST) in the Arabian Sea (AS) and Bay of Bengal (BoB) during 1880–2010 is examined using all the available data sets of monthly SST, wind speed, incoming solar radiation, ...
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!
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
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 ...
