The lab studies climate variability in the tropical and mid-latitude Atlantic,
and the tropical and subtropical Pacific. My research most commonly use materials
collected from deep sea sediment cores, but I also occasionally use sediment traps
to describe the relationship between modern processes and what is eventually deposited
on the sea floor - this has the added benefit of allowing us to calibrate paleoclimate
proxies to instrumental records.
I have active research projects in the Cariaco Basin , the circum-Caribbean
region, and at the Bermuda Rise. The Cariaco Basin contains a rich archive of tropical
Atlantic climate variability, including fluctuations in the Intertropical Convergence
Zone, trade winds, sea surface temperature, and continental vegetation. My Caribbean
studies involve the use of speleothems (cave deposits) to reconstruct regional precipitation
patterns, forcing mechanisms, and hydrographic modelling of those patterns for the
last 1,000 years. A new project has just started to explore the alterations of
sinking particles with respect to carbon fluxes, and the impact of horizontal particle
fluxes on paleoceanographic records at the Bermuda Rise. Recent past projects have
explored El Niño Southern Oscillation and Pacific Decadal Oscillation variability
using material from the Santa Barbara Basin, and sediment trap design testing in
the eastern tropical North Pacific. Click on any of the boxes above (or the links
