(Springer, 2010)Sediment underlying the oxygen minimum zone of the eastern Arabian Sea is rich in organic matter. Bacteria in this sediment-water interface are of great ecological importance as they are responsible for decomposing, ... -
18 Ka BP records of climatic changes, Bay of Bengal: Isotopic and sedimentological evidences
(Indian Academy of Sciences, 2001)Based upon the oxygen isotopic records of Globigerinoide sacculifer, the clay mineral assemblages and aridity indicator chlorite/illite (C/I) ratio, the palaeoclimatic changes during the past 18 Ka BP have been archived. ... -
18S rDNA sequencing data of benthic polychaetes from the Eastern Arabian Sea
(Elsevier, 2018)The limited DNA sequence data of the polychaetes species are available from the Eastern Arabian Sea. We have sequenced 18S rDNA gene from 54 polychaetes species and 37 species identified up to the species level. The DNA ... -
2-D model for pollutant dispersion at the coastal outfall off Paradip
(Indira Gandhi Centre for Atomic Research, Kalpakkam, India, 1999)Simulation of dispersion of the effluent discharge has been carried out using 2-D Model to verify the advection and diffusion of the pollutant patch of the proposed effluent disposal off Paradip, Orissa, India. The simulation ... -
2015-16 ENSO contributed reduction in oil sardines along the Kerala coast, south?west India
(2019)Fishery along the west coast of India largely depends on pelagic fish such as oil sardines, which are dominant during the south?west monsoon. However, the response of sardine population to the warming caused by the climatic ... -
210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
(American Geophysical Union, 2008)Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ... -
