The biostratigraphy and paleobiology of Oligocene planktonic foraminifera from the equatorial Pacific Ocean (ODP Site 1218)
Planktonic foraminifera from a continuous Oligocene succession with clear magnetochronology and sediment cycles at Ocean Drilling Program Site 1218 (equatorial Pacific Ocean) were studied in the interval from 27 to 30 Ma. Paragloborotalia taxa are common and we examined their size, relative abundance, and stable isotopes. Multispecies stable isotope data indicate the depth habitats of Oligocene...
متن کاملIntraseasonal ‘‘monsoon jets’’ in the equatorial Indian Ocean
[1] The zonal wind in the equatorial Indian Ocean (EqIO) is westerly almost throughout the year. It has a strong semiannual cycle and drives the spring and fall Wyrtki jets. In addition, high resolution daily satellite winds show ‘‘westerly wind bursts’’ lasting 10–40 days, associated with atmospheric convection in the eastern EqIO. These bursts have the potential to produce intraseasonal eastw...
متن کاملA tropospheric ozone maximum over the equatorial Southern Indian Ocean
We examine the distribution of tropical tropospheric ozone (O3) from the Microwave Limb Sounder (MLS) and the Tropospheric Emission Spectrometer (TES) by using a global three-dimensional model of tropospheric chemistry (GEOS-Chem). MLS and TES observations of tropospheric O3 during 2005 to 2009 reveal a distinct, persistent O3 maximum, both in mixing ratio and tropospheric column, in May over t...
متن کاملA biweekly mode in the equatorial Indian Ocean
The National Institute of Oceanography, Goa deployed moorings with several subsurface current meters at 0◦, 93◦E (in February 2000) and 0◦, 83◦E (in December 2000) in the eastern Indian Ocean. Observed meridional current at all depths has a 10-20 day (or biweekly) variability that is distinct from longer period (20-60 day) subseasonal variability. Lags between different instruments suggest the ...
متن کاملWind-Driven Cross-Equatorial Flow in the Indian Ocean
Meridional velocity, mass, and heat transport in the equatorial oceans are difficult to estimate because of the nonapplicability of the geostrophic balance. For this purpose a steady-state model is utilized in the equatorial Indian Ocean using NCEP wind stress and temperature and salinity data from the World Ocean Atlas 2005 (WOA05) and Argo. The results show a Somali Current flowing to the sou...
