A simple estimation of equatorial Pacific response from windstress to untangle Indian Ocean dipole and basin influences on El Nino
(Springer, 2016)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 ... -
About the role of westerly wind events in the possible development of an El Nino in 2014
(American Geophysical Union, 2014)Similarities between early 1997 and 2014 has prompted climate scientists to wonder if an El Niño matching the 1997 “El Niño of the century” could develop in 2014. Until April 2014, the equatorial Pacific exhibited positive ... -
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 ... -
Acoustic communication for Maya Autonomous Underwater Vehicle - performance evaluation of acoustic modem
(NIOT, Chennai, 2015)Autonomous underwater vehicles (AUV) traverse considerable distances underwater without any intervention. Very often the operations are in coastal waters with small depth, large horizontal distances, seabed obstacles, ... -
Acoustic reflections in the water column of Krishna-Godavari offshore basin, Bay of Bengal
(Acoustical Society of America, 2016)Seismic oceanographic studies from various oceans worldwide have indicated that the acoustic reflections are mostly observed along thermal boundaries within the water column. However, the authors present a case study of ... -
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 ... -
Assessment of existing sediment transport models for sand barrier dynamics under wave and currents
(IAHR-AIRH, 2014)The paper summarizes morphology changes over rippled sand barriers under wave and wave combined current of 27 laboratorial experiments. Data of 4 wave conditions (H=10cm, T=1s; H=12cm, T=1s; H=12cm, T=1.5s; H=14cm, T=1.5s) ... -
Assessment of seasonal and year-to-year surface salinity signals retrieved from SMOS and Aquarius missions in the Bay of Bengal
(Taylor & Francis, 2016)The Bay of Bengal (BoB) exhibits a wide range of sea surface salinity (SSS), with very fresh water induced by heavy monsoonal precipitation and river run-offs to the north, and saltier water to the south. This is a ... -
Atmospheric fine and coarse mode aerosols at different environments of India and the Bay of Bengal during winter-2014: Implications of a coordinated campaign
(Metrology Society of India, 2014)In this paper, we present mass concentrations of particulate matter [PM<sub>2.5</sub>, PM<sub>10</sub> size fractions and total suspended particulates (TSP)] measured simultaneously over land stations (Kullu, Patiala, ... -
Backtrack modeling to locate the origin of tar balls depositing along the west coast of India
(Elsevier, 2016)Tar ball (TB) deposition along the West Coast of India (WCI) is a common phenomenon during the southwest monsoon season, particularly along the coast of Goa and Gujarat, and it is a major concern to the stake holders. Our ... -
Changes in nearshore waves during the active sea/land breeze period off Vengurla, central west coast of India
(Copernicus Publications, 2016)A unique feature observed in the tropical and subtropical coastal area is the diurnal sea-breeze/land-breeze cycle. We examined the nearshore waves at 5 and 15 m water depth during the active sea/land breeze period ... -
Characteristics of long-period swells measured in the near shore regions of eastern Arabian Sea
(Elsevier, 2016)Measured wave data covering two years simultaneously at 3 locations along the eastern Arabian Sea reveals the presence of long-period (peak wave period > 18 s) low-amplitude waves (significant wave height < 1 m) and the ... -
Characteristics of shallow water waves off the central west coast of India before, during and after the onset of the Indian summer monsoon
(Elsevier, 2015)We studied the wave characteristics before, during and after the onset of the Indian summer monsoon based on data measured using the buoy moored at 3 locations off the central west coast of India. The study reveals the ... -
Chemical characterization of meltwater from East Rathong glacier vis-a-vis Western Himalayan glaciers
(Springer, 2015)Ice and meltwater samples from Rathong glacier and its pro-glacial stream Rathong chu, were collected during late winter season. Samples were analyzed to study the chemical composition , weathering, and geochemical processes ... -
Classification of tidal inlets along the Central east coast of India
(Elsevier, 2015)Coastal inlets are the openings along the coastline that provide a linkage between the open ocean and the hinterland water bodies. These coastal inlets are varied in nature depending on many influencing parameters such as ... -
Classification of tidal inlets along the central west coast of India
(Elsevier, 2015)Tidal inlets along the Maharashtra coast on the central west coast of India were classified according to three methods available in the literature. Two classification methods viz., (i) Hydrodynamic classification (Hayes, ... -
