Pyloniid stratigraphy - A new tool to date tropical radiolarian ooze from the central tropical Indian Ocean
(Elsevier, 2002)
Pyloniid stratigraphy, a faunal abundance-variation stratigraphic tool, similar to Cycladophora davisiana stratigraphy employed at high latitudes, is found to work well for tropical radiolarian ooze. The relationship between ...
Supra-generic radiolarian transfer function based late Miocene palaeomonsoonal changes in the northeastern tropical Indian Ocean
(Indian Geological Association, 1995)
A Q-mode factor analysis of the % data of 25 broadly defined supra-generic radiolarian groups in 42 deep-sea surface sediments produced four statistically significant and geographically distinct faunal assemblages related ...
Radiolarian fluxes from the southern Bay of Bengal: sediment trap results
(Pergamon, 2002)
A study of radiolarian fluxes collected during 1991-93 from time-series sediment traps deployed at 1071 and 3010 m water depth in the southern Bay of Bengal (SBBT) yielded 40 species/groups of radiolarians. Among the order ...
Supra-generic radiolarian transfer function based late Miocene palaeomonsoonal changes in the northeastern tropical Indian Ocean
(Indian Geological Association, 1995)
A Q-mode factor analysis of the % data of 25 broadly defined supra-generic radiolarian groups in 42 deep-sea surface sediments produced four statistically significant and geographically distinct faunal assemblages related ...
Radiolarian monsoonal index Pyloniid group responds to astronomical forcing in the last approx. 500,000 y ears: Evidence from the Central Indian Ocean
(Indian Society for Prehistoric and Quaternary Studies, 1999)
Pyloniid radiolarians, oceanic micro-zooplanktons (surface water dwelling), are sensitive to monsoon sea surface temperature and salinity, and their variation down a core may provide an insight into the proxy climatic ...
Record of carbonate preservation and the Mid-Brunhes climatic shift from a seamount top with low sedimentation rates in the Central Indian Basin
(John Wiley, 2013)
In the present investigation, an age model of carbonate-rich cores from a seamount top in the Central Indian Basin (CIB) was constructed using both isotopic (sup(230)Th sub(excess), AMS sup(14)C, oxygen isotopes) and ...
Quaternary radiolarian faunal changes in the tropical Indian Ocean: Inferences to paleomonsoonal oscillation of the 10 degrees S hydrographic front
(Current Science Association, Bangalore, 1997)
The northern Indian Ocean is characterized by three distinct surface water masses, i.e. (1) highly saline (greater than 34.5 ppt) Arabian Sea, (2) low saline (less than 34.5 ppt) Bay of Bengal and (3) a moderate salinity ...
