Vegetation and climate development on the North American Atlantic Coastal Plain from 33 to 13 million years ago (IODP Expedition 313)

Abstract: Abstract. We have investigated the palynology of sediment cores from Sites M0027 and M0029 of IODP Expedition 313 on the New Jersey shallow shelf, east coast of North America, spanning an age range of 33 to 13 million years before present. Additionally, a pollen assemblage from the Pleistocene was examined. The palynological results were statistically analyzed and complemented with pollen-based quantitative climate reconstructions. Transport-related bias of the pollen assemblages was identified via analysis of… Show more

“…This result is completely opposite to the picture of the cryosphere depicted in the literature; i.e., a build-up of Antarctic ice sheets reaching the present-day volume or larger, but with an ice-free Arctic (Zachos et al, 2001;Pekar and DeConto, 2006;Liebrand et al, 2011;Mawbey and Lear, 2013). Terrestrial pollen data from Denmark (Śliwińska et al, 2014), northeastern Tibet (Miao et al, 2013), and the North American Atlantic coastal plain (Kotthoff et al, 2013) support our interpretation; they show the sudden and brief expansion of conifer forests during the Mi-1 event, indicating cooling of 2-4 °C in the NH highmiddle latitude regions. This supporting evidence, with our own results, calls for a forcing mechanism that was able to drive the significant NH cooling during this episode.…”

“…Este mismo autor observó una aberración climática para este periodo en el límite Eoceno-Oligoceno, hace unos 34 millones de años aproximadamente, donde se incrementó la placa de hielo continental de la Antártida y las temperaturas decayeron. Kotthoff et al, (2013) recuperaron palinomorfos del lecho marino de la costa este de Estados Unidos en New Jersey y encontraron que para finales del Eoceno los conjuntos palinológicos contenían altos porcentajes de polen bisacado el cual corresponde a bosques de coníferas e indicaron que la temperatura media anual decreció aproximadamente 3° C en la transición Eoceno-Oligoceno.…”

“…Estas condiciones climáticas adversas aceleraron las tasas de recambio y especiación en ciertos grupos, así como la extinción de otros. Kotthoff et al, (2013) basándose en los conjuntos paleopalinológicos recuperados de sedimentos marinos de las costas de New Jersey, dedujeron que hace unos 23.4 millones de años las temperaturas eran mucho más cálidas y que estas disminuyeron entre 3 y 4° C; como consecuencia, se observó una expansión de los bosques de coníferas, reflejado en los altos porcentajes de polen bisacado recuperado de dichos sedimentos. (Zachos et al, 2001).…”
