  • Aluminum in the northwestern Indian-Ocean (Arabian Sea) 
    Upadhyay, S.; Sengupta, R. (Marine Chemistry. 47(3-4); 1994; 203-214.)
    The distribution of Al has been studied along two transects (approximately 15-degrees and 18-degrees-N) in the Arabian Sea. The waters of the Arabian Sea along the Indian coast are relatively enriched in Al (approximately ...
  • The behaviour of aluminium in waters of the Mandovi estuary, west coast of India 
    Upadhyay, S.; SenGupta, R. (Marine Chemistry. 51(3); 1995; 261-276.)
    The concentration of dissolved Al in both the freshwater (similar to 0.08-0.23 mu M) and seawater (less than or equal to 0.07 mu M) endmembers of the Mandovi estuary is low, the former being always greater in magnitude ...
  • Sorption model for dissolved aluminium in freshwaters 
    Upadhyay, S.; Liss, P.S.; Jickells, T.D. (Aquatic Geochemistry. 8(4); 2002; 255-275.)
    A series of aluminium speciation measurements were made in the freshwaters of the Yare and Great Ouse rivers (England). Samples were analysed for dissolved and particulate Al, suspended particulate matter (SPM), and other ...
  • Sorption model for dissolved and leachable particulate aluminium in the Great Ouse Estuary, England 
    Upadhyay, S. (Aquatic Geochemistry. 18(3); 2012; 243-262.)
    The behaviour of dissolved Al in the Great Ouse estuary, in particular with respect to salinity, is complex. There is, however, evidence from field data as well as laboratory mixing experiments to suggest that flocculation ...
  • Sorption model for dissolved and particulate aluminium in the Conway estuary, UK 
    Upadhyay, S. (Estuarine, Coastal and Shelf Science. 76(4); 2008; 914-919.)
    Dissolved Al carried in river water apparently undergoes a fractional removal at the early stages of mixing in the Conway estuary. On the other hand, dissolved Al behaves almost conservatively in high salinity (greater ...
