230Th derived glacial to Holocene sediment fluxes in the southern Arabian Sea: insights into carbonate sedimentation
(John Wiley & Sons, Ltd, 2021)We present a record of glacial to Holocene 230Thxs normalized sediment mass fluxes for a site located on the eastern flank of the Carlsberg Ridge, Arabian Sea to evaluate carbonate burial, preservation and surface ocean ... -
234-Th-Based Carbon Export Flux Along the Indian GEOTRACES GI02 Section in the Arabian Sea and the Indian Ocean
(John Wiley & Sons, 2018)234-Th (t1/2 = 24.1 d), present in seawater, is a naturally occurring particle-reactive radionuclide formed through the radioactive decay of its parent, 238U (t1/2 = 4.47 x 109 years). The 234Th:238U disequilibrium is ... -
234Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, 1996)We have determined the particle scavenging rates, export fluxes of @u234@@Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
26th December 2004 great Sumatra-Andaman earthquake: Co-seismic and post-seismic motions in northern Sumatra
(Elsevier, 2007)Trench-parallel thrust faults verging both landward and seaward were mapped in the portion of wedge located between northern Sumatra and the Indian-Indonesian boundary The spatial aftershocks distribution of the 26th ... -
2D NMR Studies of Bromotyrosine Alkaloid, Purpurealidin K from Marine Sponge Psammaplysilla purpurea
(2019)Marine sponges of the order Verongida and related organisms are the richest source of bioactive bromotyrosine alkaloids. Purpurealidin K (1) along with purealidin Q (2), aerophobin 2 (3) and aplysamine 2 (4) were isolated ... -
