Project OC3 - Methods

Sedimentological, geochemical, and biological proxies for SST and paleosalinity (carbonate and opal-based), sea-ice (diatoms), atmospheric dust (sediment and ice), and thermocline depth (foraminifera).
High-resolution core scanning; dating (210Pb, 226Ra, 14C).
Numerical simulations using the comprehensive climate model CCSM3 including dynamical vegetation and dust-transport modules.
