Deep-sea temperature and circulation changes at the Paleocene-Eocene Thermal Maximum.
A rapid increase in greenhouse gas levels is thought to have fueled global warming at the Paleocene-Eocene Thermal Maximum (PETM). Foraminiferal magnesium/calcium ratios indicate that bottom waters warmed by 4 degrees to 5 degrees C, similar to tropical and subtropical surface ocean waters, implying no amplification of warming in high-latitude regions of deep-water formation under ice-free cond...
متن کاملSurviving rapid climate change in the deep sea during the Paleogene hyperthermals.
Predicting the impact of ongoing anthropogenic CO2 emissions on calcifying marine organisms is complex, owing to the synergy between direct changes (acidification) and indirect changes through climate change (e.g., warming, changes in ocean circulation, and deoxygenation). Laboratory experiments, particularly on longer-lived organisms, tend to be too short to reveal the potential of organisms t...
متن کاملThermal Maximum 2 and H2 High-resolution deep-sea carbon and oxygen isotope records of Eocene
Eocene Thermal Maximum 2 (ETM2) and H2 were two short-lived global warming events that occurred ~2 m.y. after the Paleocene–Eocene thermal maximum (PETM, ca. 56 Ma). We have generated benthic foraminiferal stable carbon and oxygen isotope records of four sites along a depth transect on Walvis Ridge (~3.5–1.5 km paleodepth, southeast Atlantic Ocean) and one site on Maud Rise (Weddell Sea) to con...
متن کاملWarming the Fuel for the Fire: Evidence for the Thermal Dissociation of Methane Hydrate During the Paleocene-Eocene Thermal Maximum
Dramatic warming and upheaval of the carbon system at the end of the Paleocene Epoch have been linked to massive dissociation of sedimentary methane hydrate. However, testing the Paleocene-Eocene thermal maximum hydrate dissociation hypothesis has been hindered by the inability of available proxy records to resolve the initial sequence of events. The cause of the Paleocene-Eocene thermal maximu...
