Paleoceneeocene Thermal Maximum


PaleoceneEocene Thermal Maximum PETM, also called Initial Eocene Thermal Maximum IETM, a short interval of maximum temperature lasting approximately 100,000 years during the late Paleocene and early Eocene epochs roughly 55 million years ago. The interval was characterized by the highest global temperatures of the Cenozoic Era 65 million years ago to the present.

Paleoceneeocene Thermal Maximum Explained


The onset of the PaleoceneEocene Thermal Maximum has been linked to an initial 5 C temperature rise and to extreme changes in Earths carbon cycle. The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe more specifically, there was a large decrease in 13 C 12 C ratio of marine and terrestrial carbonate s and organic carbon.

The PaleoceneEocene Thermal Maximum PETM is one of the most intense and abrupt intervals of global warming in the geological record. It occurred around 56 million years ago, at the boundary between the Paleocene and Eocene epochs. This warming has been linked to a similarly rapid increase in the concentration of greenhouse gases in Earth.

Aug 30, 2017 Abstract. The PalaeoceneEocene Thermal Maximum 1,2 PETM was a global warming event that occurred about 56 million years ago, and is commonly thought to have been driven primarily by the destabilization of carbon from surface sedimentary reservoirs such as methane hydrates 3. However, it remains controversial whether such reservoirs were indeed.

Response Of Antarctic Odp Site 690 Planktonic


1 Highresolution study of Antarctic planktonic foraminiferal assemblages Ocean Drilling Program Site 690, Weddell Sea shows that these microplankton underwent a stepwise series of changes during the PaleoceneEocene thermal maximum PETM. Initiation of this response coincides with the onset of the carbon isotope excursion CIE but precedes the benthic foraminiferal mass extinction.

The PaleoceneEocene thermal maximum PETM 56 Ma was a transient global warming event associated with a huge perturbation to the global carbon cycle. Changes in marine biological productivity may have contributed to the rapid recovery from this climate change event, by driving the burial of inorganic and organic carbon.

The Coupling Of Climate And Carbon Cycle During The Late


Much work has focused on determining the sensitivities of sea surface pH, climate and the hydrologic cycle to carbon release during the largest hyperthermal of the Cenozoic, the PaleoceneEocene Thermal Maximum PETM ca. 56 Ma. However, Eocene Thermal Maximum 2 ETM2 ca. 54 Ma provides a secondary calibration point on assessing the.

Instructors may want to preface this activity by discussing the importance of the PaleoceneEocene Thermal Maximum in Earths climate. If a more constructivist approach to learning is followed, then this activity would provide a good foundation of information about the role foraminifera play in helping scientists reconstruct ocean temperature.
