Dynamics of trace metals in sediments of a seasonally hypoxic coastal zone in the southeastern Arabian Sea
Dayana, M.; Gireeshkumar, T.R.; Shameem, K.; Furtado, C.M.; Arya, K.S.; Udayakrishnan, P.B.; Balachandran, K.K. (Elsevier, 2022)This study examined the effect of water column hypoxia on the distribution and geochemical fractionation of trace metals in the seasonally hypoxic coastal environment in the southeastern Arabian Sea.Water and surface ... -
Factors determining variations in viral abundance and viral production in a tropical estuary influenced by monsoonal cycles
Jasna, V.; Parvathi, A.; Aswathy, V.K.; Aparna, S.; Dayana, M.; Aswathy, A.J.; Madhu, N.V. (Elsevier, 2019)Viruses are the most abundant, dynamic, and ubiquitous components in the marine and estuarine environments. They outnumber prokaryotes in their abundance by at least one order of magnitude, but their relationship varies ... -
