Abstract

Centennial-scale records of sea-surface temperature and opal composition spanning the Last Glacial Maximum and Termination 1 (circa 25-6ka) are presented here from Guaymas Basin in the Gulf of California. Through the application of two organic geochemistry proxies, the U 37 K index and the TEX 86 H index, we present evidence for rapid, stepped changes in temperatures during deglaciation. These occur in both temperature proxies at 13ka (∼3C increase in 270years), 10.0ka (∼2°C decrease over ∼250years) and at 8.2ka (3C increase in
