Western Pacific thermocline structure and the Pacific marine Intertropical Convergence Zone during the Last Glacial Maximum
Paleoclimate proxy evidence suggests a southward shift of the Intertropical Convergence Zone (ITCZ) during times of Northern Hemisphere cooling, including the Last Glacial Maximum, 19–23 ka before present. However, evidence for movement over the Pacific has mainly been limited to precipitation reconstructions near the continents, and the position of the Pacific marine ITCZ is less well constrai...
متن کاملRadiocarbon as a thermocline proxy for the eastern equatorial Pacific
[1] An ocean model is used to test the idea that sea surface DC behaves as a thermocline proxy in the eastern equatorial Pacific. The ORCA2 model, which includes DC as a passive tracer, has been forced with reanalysis fluxes over 1948–1999, and the output is compared with a previously reported Galapagos DC record. The model reproduces the abrupt increase in the seasonally minimum DC in 1976/77 ...
متن کاملDeep-reaching thermocline mixing in the equatorial pacific cold tongue
Vertical mixing is an important factor in determining the temperature, sharpness and depth of the equatorial Pacific thermocline, which are critical to the development of El Ninõ and Southern Oscillation (ENSO). Yet, properties, dynamical causes and large-scale impacts of vertical mixing in the thermocline are much less understood than that nearer the surface. Here, based on Argo float and the ...
متن کاملSynchronous deglacial thermocline and deep-water ventilation in the eastern equatorial Pacific
The deep ocean is most likely the primary source of the radiocarbon-depleted CO2 released to the atmosphere during the last deglaciation. While there are well-documented millennial scale Δ14C changes during the most recent deglaciation, most marine records lack the resolution needed to identify more rapid ventilation events. Furthermore, potential age model problems with marine Δ14C records may...
متن کاملNorth Atlantic Deep Water Production during the Last Glacial Maximum
Changes in deep ocean ventilation are commonly invoked as the primary cause of lower glacial atmospheric CO2. The water mass structure of the glacial deep Atlantic Ocean and the mechanism by which it may have sequestered carbon remain elusive. Here we present neodymium isotope measurements from cores throughout the Atlantic that reveal glacial-interglacial changes in water mass distributions. T...
