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 ... -
A modeling study of the processes of surface salinity seasonal cycle in the Bay of Bengal.
Akhil, V.P.; Durand, F.; Lengaigne, M.; Vialard, J.; Keerthi, M.G.; Gopalakrishna, V.V.; Deltel, C.; Papa, F.; Montegut, C.deB. (AGU, 2014)In response to the Indian Monsoon freshwater forcing, the Bay of Bengal exhibits a very strong seasonal cycle in sea surface salinity (SSS), especially near the mouths of the Ganges-Brahmaputra and along the east coast of ... -
Bay of Bengal Sea surface salinity variability using a decade of improved SMOS re-processing
Akhil, V.P.; Vialard, J.; Lengaigne, M.; Keerthi, M.G.; Boutin, J.; Vergely, J.L.; Papa, F. (Elsevier Inc., 2020)Monsoon rain and rivers bring large freshwater input to the Northern Bay of Bengal (BoB), yielding low Sea Surface Salinity (SSS) after the monsoon. The resulting sharp upper-ocean salinity stratification is thought to ... -
Ganga-Brahmaputra river discharge from Jason-2 radar altimetry: An update to the long-term satellite-derived estimates of continental freshwater forcing flux into the Bay of Bengal
Papa, F.; Bala, S.K.; Pandey, R.K.; Durand, F.; Gopalakrishna, V.V.; Rahman, A.; Rossow, W.B. (American Geophysical Union, 2012)This paper discusses the use of Jason-2 radar altimeter measurements to estimate the Ganga-Brahmaputra surface freshwater flux into the Bay of Bengal for the period mid-2008 to December 2011. A previous estimate was generated ... -
Improved Bathymetric Dataset and Tidal Model for the Northern Bay of Bengal
Krien, Y.; Mayet, C.; Testut, L.; Durand, F.; Tazkia, A.R.; Islam, A.K.M.S.; Gopalakrishna, V.V.; Becker, M.; Calmant, S.; Shum, C.K.; Khan, Z.H.; Papa, F.; Ballu, V. (Taylor & Francis, 2016)The Bengal Delta is a highly complex and vulnerable environment where key dynamical features such as tides, storm surges, salinity, and sediment transport strongly depend on the accurate bottom topography representation. ... -
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 ... -
Recent salinity intrusion in the Bengal delta: Observations and possible causes
Sherin, V.R.; Durand, F.; Papa, F.; Islam, A.K.M.S.; Gopalakrishna, V.V.; Khaki, M.; Suneel, V. (Elsevier Ltd, 2020)Salinization stands among the most prominent environmental hazards of the largest delta on Earth, the Bengal delta. It has significant impacts on the local societies and the economy. Using an unprecedented collection of ... -
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 ...
