A modeling study of processes controlling the Bay of Bengal sea surface salinity interannual variability
Akhil, V.P.; Lengaigne, M.; Vialard, J.; Durand, F.; Keerthi, M.G.; Chaitanya, A.V.S.; Papa, F.; Gopalakrishna, V.V.; Montegut, de B.C. (John Wiley & Sons, Ltd, 2016)Recent observational studies provided preliminary insights on the interannual variability of Bay of Bengal (BoB) Sea Surface Salinity (SSS), but are limited by the poor data coverage. Here, we describe the BoB interannual ... -
Assessment of seasonal and year-to-year surface salinity signals retrieved from SMOS and Aquarius missions in the Bay of Bengal
Akhil, V.P.; Lengaigne, M.; Durand, F.; Vialard, J.; Chaitanya, A.V.S.; Keerthi, M.G.; Gopalakrishna, V.V.; Boutin, J.; de Boyer, M.C. (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 ... -
Modulation of the Ganges-Brahmaputra River Plume by the Indian Ocean Dipole and Eddies Inferred From Satellite Observations
Fournier, S.; Vialard, J.; Lengaigne, M.; Lee, T.; Gierach, M.M.; Chaitanya, A.V.S. (Wiley, 2017)The Bay of Bengal receives large amounts of freshwater from the Ganga?Brahmaputra (GB) river during the summer monsoon. The resulting upper?ocean freshening influences seasonal rainfall, cyclones, and biological productivity. ... -
Monsoon rainfall and contrasting source rocks influenced sediment composition of peninsular basins along the east coast of India (western Bay of Bengal)
Peketi, A.; Mazumdar, A.; Pillutla, S.P.K.; Rai, V.K.; Sawant, B.; Chaitanya, A.V.S.; Krishna, R. (Elsevier Ltd, 2020)The peninsular India is characterized by remarkable variation in lithological composition as well as contrasting rainfall distribution patterns. The erosional and weathering history of these source rocks along with monsoonal ... -
Observed year-to-year sea surface salinity variability in the Bay of Bengal during the 2009–2014 period
Chaitanya, A.V.S.; Durand, F.; Mathew, S.; Gopalakrishna, V.V.; Papa, F.; Lengaigne, M.; Vialard, J.; KranthiKumar, C.; Venkatesan, R. (Springer, 2015)The present study describes the observed sea surface salinity (SSS) interannual variability in the Bay of Bengal over the 2009–2014 period. It is based on an original compilation of all available in situ SSS observations ... -
Salinity measurements collected by fishermen reveal a ``River in the Sea`` flowing along the eastern coast of India
Chaitanya, A.V.S.; Lengaigne, M.; Vialard, J.; Gopalakrishna, V.V.; Durand, F.; KranthiKumar, C.; Amritash, S.; Suneel, V.; Papa, F.; Ravichandran, M. (American Meteorological Society, 2014)Being the only tropical ocean bounded by a continent to the north, the Indian Ocean is home to the most powerful monsoon system on Earth. Monsoonal rains and winds induce huge river discharges and strong coastal currents ... -
Signature of Indian Ocean Dipole on the western boundary current of the Bay of Bengal
Sherin, V.R.; Durand, F.; Gopalkrishna, V.V.; Anuvinda, S.; Chaitanya, A.V.S.; Bourdalle-Badie, R.; Papa, F. (Elsevier, 2018)This study uses an unprecedented collection of 27 years of repeated eXpendable Bathy Thermograph (XBT) sections crossing the western and north-western boundaries of the Bay of Bengal (BoB). Our objective is to analyse the ...
