AB: During the Paleocene Eocene Thermal Maximum, global temperatures rose dramatically and rapidly due to the release of methane clatherates from the ocean floor. The trigger of this event is still unknown, however it is likely tied to the global carbon and sulfur cycles. Marine barite (BaSO₄) found in ocean sediments precipitates continuously in the water column and does not alter diagenetically over time which enables us to measure the sulfur isotopes over the PETM. A high resolution sulfur curve over the PETM that will help us understand the causes of the Thermal Maximum and a barite accumulation rate record will be presented and discussed.
