North Atlantic marine biogenic silica accumulation through the early to middle Paleogene: implications for ocean circulation and silicate weathering feedback

Autor: J. Witkowski, K. Bryłka, S. M. Bohaty, E. Mydłowska, D. E. Penman, B. S. Wade

Publikováno v: Climate of the Past, Vol 17, Pp 1937-1954 (2021)

The Paleogene history of biogenic opal accumulation in the North Atlantic provides insight into both the evolution of deepwater circulation in the Atlantic basin and weathering responses to major climate shifts. However, existing records are compromi

New composite bio- and isotope stratigraphies spanning the Middle Eocene Climatic Optimum at tropical ODP Site 865 in the Pacific Ocean

Autor: K. M. Edgar, S. M. Bohaty, H. K. Coxall, P. R. Bown, S. J. Batenburg, C. H. Lear, P. N. Pearson

Publikováno v: Journal of Micropalaeontology, Vol 39, Pp 117-138 (2020)

The Middle Eocene Climatic Optimum (MECO) at ca. 40 Ma is one of the largest of the transient Eocene global warming events. However, it is relatively poorly known from tropical settings since few sites span the entirety of the MECO event and/or hos

Tropical Atlantic climate and ecosystem regime shifts during the Paleocene–Eocene Thermal Maximum

Autor: J. Frieling, G.-J. Reichart, J. J. Middelburg, U. Röhl, T. Westerhold, S. M. Bohaty, A. Sluijs

Publikováno v: Climate of the Past, Vol 14, Pp 39-55 (2018)

The Paleocene–Eocene Thermal Maximum (PETM, 56 Ma) was a phase of rapid global warming associated with massive carbon input into the ocean–atmosphere system from a 13C-depleted reservoir. Many midlatitude and high-latitude sections have been s

Expansion and diversification of high-latitude radiolarian assemblages in the late Eocene linked to a cooling event in the southwest Pacific

Autor: K. M. Pascher, C. J. Hollis, S. M. Bohaty, G. Cortese, R. M. McKay, H. Seebeck, N. Suzuki, K. Chiba

Publikováno v: Climate of the Past, Vol 11, Iss 12, Pp 1599-1620 (2015)

The long-term cooling trend from middle to late Eocene was punctuated by several large-scale climate perturbations that culminated in a shift to "icehouse" climates at the Eocene–Oligocene transition. We present radiolarian micro-fossil assemblage

Astronomical calibration of the geological timescale: closing the middle Eocene gap

Autor: T. Westerhold, U. Röhl, T. Frederichs, S. M. Bohaty, J. C. Zachos

Publikováno v: Climate of the Past, Vol 11, Iss 9, Pp 1181-1195 (2015)

To explore cause and consequences of past climate change, very accurate age models such as those provided by the astronomical timescale (ATS) are needed. Beyond 40 million years the accuracy of the ATS critically depends on the correctness of orbital

Small but mighty: how overlooked small species maintain community structure through middle Eocene climate change

Autor: L. E. Kearns, S. M. Bohaty, K. M. Edgar, T. H. G. Ezard

Publikováno v: Paleobiology. 49:77-98

Understanding current and future biodiversity responses to changing climate is pivotal as anthropogenic climate change continues. This understanding is complicated by the multitude of available metrics to quantify dynamics and by biased sampling prot
