Detailed Description
Multicores collected from the northern Gulf of Mexico. These cores contain roughly 1 meter of sediment from the seafloor, and represent the past ~2000 years of deposition. USGS scientists slice these cores in 5 mm increments, and analyze the chemical composition of microfossils (e.g., foraminifera) and molecular fossils (e.g., alkenones, GDGTs, leaf waxes, etc.), to generate paleoclimate records over the past 2 millennia.
