Climatically driven changes in oceanic processes throughout the equatorial Pacific

Creator:

Paytan, Adina, Lyle, Mitchell, Mix, Alan C., and Chase, Zanna

Abstract:

The mass accumulation rates of sedimentary components (carbonate, organic carbon, opal, barite, reactive phosphate, iron, terrigenous minerals, etc.) are used in many paleoceanographic reconstructions to learn about temporal and spatial changes in surficial Earth processes including wind stress and direction, oceanic circulation, weathering rates, marine productivity and ecosystem structure, climate...

Patterns of CaCO₃deposition in the eastern tropical Pacific Ocean for the last 150 kyr: Evidence for a southeast Pacific depositional spike during marine isotope stage (MIS) 2

Creator:

Lyle, Mitchell, Mix, Alan C., and Pisias, Nicklas G.

Abstract:

We constructed biogenic mass accumulation rate (MAR) time series for eastern Pacific core transects across the equator at ~105˚and ~85˚W and along the equator from 80˚to 140˚W. We used empirical orthogonal function (EOF) analysis to extract spatially coherent patterns of CaCO₃deposition for the last 150 kyr. EOF mode 1 (51%...

Increased dissolved terrestrial input to the coastal ocean during the last deglaciation

Creator:

Klinkhammer, Gary P., Mix, Alan C., and Haley, B. A.

Abstract:

Here we present the first downcore results for a new paleoproxy, the Mn/Ca ratio of foraminiferal calcite, applied to sediment accumulated in the extreme Eastern Tropical North Pacific (ETNP) over the last 30,000 years. The Mn/Ca results are compared to oxygen isotopes and sea surface temperature calculated from Mg/Ca. We...
