Description:
Ocean monitoring over the past several decades has shown that fluctuations of fish stocks in the California Current are to linked climate changes on inter-decadal time scales. However, few records, if any, are unambiguous enough to provide a context for these observations over longer time periods. One particularly promising and little-studied location is the bottom of an anoxic basin at 25oN off Baja California that may yield a ~500 yr with decadal to interannual resolution. A ~1-m long core was successfully collected on this location in October 2007 using a box corer and immediately flash frozen on shipboard to preserve all stratigraphic information. The focus of this project over the summer will be to (1) obtain a detailed record of variations in diffuse spectral reflectance (color) from a thawed slab of this core, and (2) embed another slab in epoxy and obtain an ultra-high resolution (
