Holocene variability in chemical weathering and ocean redox state: A reconstruction using sediment geochemistry of the Arabian Sea
(Elsevier, 2022)
Major and trace elemental geochemistry of a sediment core (SSK40/GC10; water depth ~50 m) from the eastern Arabian Sea (17� 59.89123 N, 72� 22.45161 E) have been investigated to reconstruct the continental weathering pattern ...
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 ...
Aragonite pteropod abundance and preservation records from the Maldives, equatorial Indian Ocean: Inferences on past oceanic carbonate saturation and dissolution events
(2019)
During the International Ocean Discovery Program (IODP) Expedition 359, a long continuous carbonate-rich sequence was recovered from the Inner Sea of Maldives. We investigated pteropod proxies (absolute abundance of pteropods ...
Early diagenetic processes affecting nutrients in the pore waters of Central Indian Ocean cores
(Elsevier, 1989)
Pore-water nutrients, nitrite, nitrate, phosphate, silicate, pH and solid-phase organic carbon were analysed for one core from the Arabian Sea and three cores from the manganese nodule area in the Central Indian Ocean ...
Basalt microlapilli in deep sea sediments of Indian Ocean in the vicinity of Vityaz fracture zone
(Geological Society of India, 1989)
Two cores recovered from the flanks of Mid-India oceanic ridge in the vicinity of Vityaz fracture zone consist of discrete pyroclastic layers at various depths. These layers are composed of coarse-grained, angular basaltic ...
Marine minerals: The Indian perspective
(1988)
The sea floor of the continental margins of India is covered by a wide variety of terrigenous, biogenous, and chemogenous mineral deposits. Terrigenous heavy mineral placers containing ilmenite, magnetite, monazite, zircon, ...
Modified interstitial water squeezer for trace metal analysis
(CSIR-NISCAIR, 1988)
Hydraulic squeezer of Manheim, used in the extraction of pore water of sediments, has been modified by providing teflon inner lining and increasing the volume of squeezer. The modified version facilitates collection of ...
A~30 kyr sub-centennial to millennial Indian summer monsoon variability record from the southern Andaman Sea, northeastern Indian Ocean
(Elsevier, 2022)
This paper reports centennial-scale variations in the Indian summer monsoon (ISM) that induced stratification and resultant productivity changes in the southern Andaman Sea. The study is based on foraminifera assemblages ...
Manpower
(New Delhi: Department of Ocean Development, 1988)
The recruitment, training and deployment of manpower for scientific work during an oceanographic expedition is discussed. Fifty scientists and 50 technicians in various disciplines of oceanography were recruited. A training ...
Shell weights of foraminifera trace atmospheric CO2 from the Miocene to Pleistocene in the central Equatorial Indian Ocean
(Springer, 2020)
The Maldives Sea is a region dominated by the South Asian monsoon (SAM) and at present, a CO2 source to the atmosphere. Ti/Al elemental ratios from Site U1467 and U1468 recovered from the Maldives Sea show a gradual increase ...
