Super ENSO and Global Climate Oscillations at Millennial Time Scales
The late Pleistocene history of seawater temperature and salinity variability in the western tropical Pacific warm pool is reconstructed from oxygen isotope (δ18O) and magnesium/calcium composition…
Magnitude and timing of temperature change in the Indo-Pacific warm pool during deglaciation
TLDR
Observations suggest that the tropical Pacific region plays an important role in driving glacial—interglacial cycles, possibly through a system similar to how El Niño/Southern Oscillation regulates the poleward flux of heat and water vapour.
Decline of surface temperature and salinity in the western tropical Pacific Ocean in the Holocene epoch
TLDR
The data imply either that the Pacific basin as a whole has become progressively less salty or that the present salinity gradient along the Equator has developed relatively recently.
The nitrogen isotope biogeochemistry of sinking particles from the margin of the Eastern North Pacific
Chemoautotrophy in the redox transition zone of the Cariaco Basin: A significant midwater source of organic carbon production
During the CARIACO time series program, microbial standing stocks, bacterial production, and acetate turnover were consistently elevated in the redox transition zone (RTZ) of the Cariaco Basin, the…
An 8-century tropical Atlantic SST record from the Cariaco Basin: Baseline variability, twentieth-century warming, and Atlantic hurricane frequency
[1] We present the first direct comparison and calibration of a downcore foraminiferal Mg/Ca record to historical instrumental sea surface temperature (SST). Mg/Ca measured on the planktic…

Climate and hydrographic variability in the Indo‐Pacific Warm Pool during the last millennium
Planktonic foraminiferal Mg/Ca and δ18O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long‐term cooling and freshening trend, as well as…
Increased northeast Pacific climatic variability during the warm middle Holocene
We use a pair of decadally resolved planktonic foraminiferal δ18O records from Santa Barbara Basin (SBB) to show that the warmest interval of the current interglacial, the middle Holocene, was…
