Abstract The Mg/Ca of marine calcareous Planktic Foraminifera (PF) shells is commonly used for sea surface temperature reconstructions. However, compared to open marine environments, hypersaline (>40) oligotrophic seas have been shown to accommodate

Autor: Kimberley K. Mayfield, Tristan J. Horner, Adi Torfstein, Maureen E. Auro, Peter W. Crockford, Adina Paytan

Publikováno v: Frontiers in Earth Science, Vol 12 (2024)

The isotopic composition of barium (δ138Ba) has emerged as a powerful tracer of deep-ocean circulation, water mass provenance, and the oceanic Ba cycle. Although the δ138Ba of water masses is primarily controlled by the balance between pelagic bari

Productivity feedback did not terminate the Paleocene-Eocene Thermal Maximum (PETM)

Autor: A. Torfstein, G. Winckler, A. Tripati

Publikováno v: Climate of the Past, Vol 6, Iss 2, Pp 265-272 (2010)

The Paleocene-Eocene Thermal Maximum (PETM) occurred approximately 55 million years ago, and is one of the most dramatic abrupt global warming events in the geological record. This warming was triggered by the sudden release of thousands of gigatons
