Modern and past climate variability in the eastern Pacific warm pool

Creator:

Benway, Heather M.

Abstract:

Westward transport of water vapor across the Panama Isthmus helps to maintain the salinity contrast between the Atlantic and Pacific Oceans, important in thermohaline circulation and global climate. Relatively low sea-surface salinities and a strong, shallow pycnocline in the eastern Pacific warm pool (EPWP) region near Central America reflect high...

Benway, Heather M., Mix, Alan C., Haley, Brian A., and Klinkhammer, Gary P.

Abstract:

Multiproxy geologic records of δ18O and Mg/Ca in fossil foraminifera from sediments under the Eastern Pacific Warm Pool (EPWP) region west of Central America document variations in upper ocean temperature, pycnocline strength, and salinity (i.e., net precipitation) over the past 30 kyr. Although evident in the paleotemperature record, there is...
