Subtropical Arctic Ocean temperatures during the Palaeocene/Eocene thermal maximum

Article Abstract:

The Palaeocene/Eocene thermal maximum in a marine sedimentary sequence obtained during the Arctic Coring Expedition is identified and shown that sea surface temperatures near the North Pole increased from ~18 degree C to over 23 degree C during this event. The analyses have shown that higher-than-modern greenhouse gas concentrations must have operated in conjunction with other feedback mechanisms to amplify early Palaeocene polar temperatures.

A humid climate state during the Palaeocene/Eocene thermal maximum

Article Abstract:

The significant differences between marine and terrestrial carbon isotope records spanning the Palaeocene/Eocene boundary thermal maximum (PETM) is demonstrated. The data and models are integrated to identify the carbon cycle processes responsible for amplifying the terrestrial carbon isotope excursion (CIE) signal.

Astronomical pacing of late Palaeocene to early Eocene global warming events

Article Abstract:

Distinct carbonate-poor red clay layers in deep-sea cores from Walvis ridge, which is termed the Elmo horizon, is reported. Deposition of the Elmo horizon at about 2 million years after the Palaeocene-Eocene thermal maximum is estimated using orbital tuning.
