Late Paleocene Thermal Maximum
The early Eocene Climatic Optimum (EECO) was followed by a 17-My-long trend toward cooler or warmer conditions?
Cooler
the era of the last 65 million years
cenozoic
What was the Late Paleocene Thermal Maximum aberration characterized by?
a 5 to 6 degree C in deep-sea temperature in less than 10 ky
What high-resolution deep-sea element is used to to track trends of warming and cooling?
Oxygen
brief but extreme excursions often associated with profound impacts on global environments and the biosphere
transient events
About how long was the recovery of the Late Paleocene Thermal Maximum aberration?
200 ky from the onset of the event
How does the climate vary during all intervals characterized by glaciation?
in a quasi-periodic fashion
anomalies that stand out well above normal background variability in terms of rate or amplitude and are usually accompanied by a major perturbation in the global carbon cycle
abberations
What were the two climate aberrations (not Late Paleocene Thermal Maximum) characterized by?
positive oxygen isotope excursions that reflect brief extremes in Antarctic ice-volume and temperature.
Following the cooling and rapid expansion of Antarctic continental ice-sheets in the earliest Oligocene, did deep-sea δ18 O values remain high or low?
high ( >2.5% )
the distribution of solar energy throughout the earth, both latitudinally and seasonally
orbital forcing/pacing
What were the Oi-1 and Mi-1 aberrations both accompanied by?
accelerated rates of turnover and speciation in certain groups of biota
The long-term pattern of deep-sea warming and cooling is consistent with reconstructions of what early subpolar climates based on both marine and terrestrial geochemical and fossil evidence?
Cenozioc
