Himalayan sedimentary pulses recorded by silicate detritus within a ferromanganese crust from the Central Indian Ocean
Banakar, V.K.; Galy, A.; Sukumaran, N.P.; Parthiban, G.; Volvaiker, A.Y. (Elsevier, 2003)A Central Indian Ocean deep-water seamount hydrogenous ferromanganese crust (SS663-Crust) contains variable (7-23%) amounts of detrital material (silicate-detritus). Taking into account the growth rate of the authigenic ... -
Indian Ocean circulation and productivity during the last glacial cycle
Piotrowski, A.M.; Banakar, V.K.; Scrivner, A.E.; Elderfield, H.; Galy, A.; Dennis, A. (Elsevier, 2009)The Indian Ocean is an important part of the global thermohaline circulation system, receiving deep waters sourced from the Southern Ocean and being the location of upwelling and surface-ocean current flow which returns ... -
Interhemispheric controls on deep ocean circulation and carbon chemistry during the last two glacial cycles
Wilson, D.J.; Galy, A.; Piotrowski, A.M.; Banakar, V.K. (American Geophysical Union, 2015)Changes in ocean circulation structure, together with biological cycling, have been proposed for trapping carbon in the deep ocean during glacial periods of the Late Pleistocene, but uncertainty remains in the nature and ... -
Quaternary climate modulation of Pb isotopes in the deep Indian Ocean linked to the Himalayan chemical weathering
Wilson, D.J.; Galy, A.; Piotrowski, A.M.; Banakar, V.K. (Elsevier, 2015)We use reductive sediment leaching to extract lead (Pb) from the authigenic fraction of marine sediments and reconstruct the Pb isotope evolution of the deep central Indian Ocean over the past 250 thousand years at ~3 kyr ...
