Distribution and fractionation of rare earth elements and Yttrium in suspended and bottom sediments of the Kali estuary, western India
Suja, S.; Fernandes, L.L.; Rao, V.P. (Springer, 2017)Concentrations of rare earth elements (REE) and yttrium (Y), and major metals (Al, Fe and Mn) were measured in suspended particulate matter (SPM) and bottom sediments of the Kali estuary, western India, for their distribution ... -
Estuarine turbidity maximum in six tropical minor rivers, central west coast of India
Fernandes, L.L.; Rao, V.P.; Kessarkar, P.M.; Suja, S. (IWA Publishing, 2018)Understanding patterns of erosion and sedimentation and their driving mechanisms is important for formulating a variety of estuarine management issues (conservation, shoreline protection, navigation, dredging and embanking). ... -
Geochemistry of sediments in contact with oxygen minimum zone of the eastern Arabian Sea: Proxy for palaeo-studies
Kessarkar, P.M.; Fernandes, L.L.; Parthiban, G.; Kurian, S.; Shenoy, D.M.; Pattan, J.N.; Rao, V.P.; Naqvi, S.W.A.; Verma, Swati (Springer, 2022)The Arabian Sea encompasses oxygen minimum zone with denitrifying conditions.
