Calibration of paleoclimate proxies in planktonic foraminifera from the Santa Barbara Basin.
Dorthy Pak (Researcher), James Kennett, David Lea

Determination of glacial/interglacial tropical sea surface temperatures using Mg/Ca paleothermometry in planktonic foraminifera.
Dorthy Pak (Researcher), David Lea

Evidence of late middle Eocene deep water circulation and climate changes using stable isotopes of foraminifera from the western subtropical Atlantic.
Dorthy Pak (Researcher)

The timing and magnitude of the latest Paleocene isotopic excursion and benthic foraminiferal extinction event in the subtropical Atlantic; implications for warm saline deepwater production.
Dorthy Pak (Researcher), Mimi Katz (Lamont-Doherty Earth Observatory)

Correlation between surface and borehole site characteristics (including geology, P- and S-wave velocity, depth to bedrock, etc...) with ground motion amplification.
Jamison Steidl (Researcher)

Establishing the "reference" site in seismic hazard estimation. Is a surface rock site a good reference site?
Jamison Steidl (Researcher)

Site response study using aftershocks from the 1994 Northridge earthquake and instruments from the SCEC portable deployment.
Jamison Steidl (Researcher)

Using marine magnetic and bathymetric data to solve for relative plate motions of the Cocos, Nazca, and Pacific plates through the Neogene.
Doug Wilson (Researcher)

Using worldwide plate motion solutions to calibrate the Cenozoic time scale. Rather than using a spline to prevent abrupt rate changes on a single plate pair, I am trying to minimize simultaneous accelerations on unrelated plate pairs.
Doug Wilson (Researcher)

Reconstructing the tectonic setting of California volcanic fields and sedimentary basins.
Doug Wilson (Researcher), P. McCrowry (USGS), R. Stanley (USGS)

Crustal structure of oceanic crust formed at 200 mm/yr spreading rate. A research cruise is tentatively scheduled for Jan.-Feb. 1999 in the Guatemala basin area of the Eastern Pacific, on the research vessel Maurice Ewing for surveying in preparation for possible future sampling by the Ocean Drilling Program.
