Krauss F.Baggenstos D.Schmitt J.Tuzon B.Menking J.A.Mächler L.Silva L.Grimmer M.Capron E.Stocker T.F.Bauska T.K.Fischer H.
Category 1: Peer-reviewed literature

Using high-precision ice core measurements of CO2, ?13C-CO2, CH4, and N2O, this study provides carbon isotope constraints on a sizeable, centennial-scale CO2 jump at the onset of Marine Isotope Stage 9 (MIS 9). The very end of the Heinrich stadial (HS) characterizing Termination IV (T-IV, ca.

AMOC Modulates Ocean Heat Content During Deglaciations Geophysical Research Letters, 2025 (Ref: 17241)

Grimmer M.Baggenstos D.Schmitt J.Krauss F.Shackleton S.Severinghaus J.P.Fischer H.
Category 1: Peer-reviewed literature

During deglaciations, Earth takes up vast amounts of energy, about half of which heats the global ocean. Thus, ocean heat content (OHC) is a key metric to assess Earth's energy budget.

Benthic d18O records Earth's energy imbalance. Nature Geoscience, 2023 (Ref: 17088)
Authors:
Shackelton S.Seltzer A.M.Baggenstos D.Lisiecki L.
Category 1: Peer-reviewed literature

Oxygen isotope ratios (d18O) of foraminifera in marine sediment records have fundamentally shaped our understanding of the ice ages and global climate change. Interpretation of these records has, however, been challenging because they reflect contributions from both ocean temperature and ice volume.

Laser-induced sublimation extraction for centimeter-resolution multi-species greenhouse gas analysis on ice cores. Atmospheric Measurement Techniques, 2023 (Ref: 17089)
Authors:
Machler L.Baggenstos D.Krauss F.Schmitt J.Bereiter B.Walther R.Reinhard C.Tuzson B.Emmenegger L.Fischer H.
Category 1: Peer-reviewed literature

Precision, accuracy, and temporal resolution are key to making full use of atmospheric trace gas records in ice cores. These aspects will become especially crucial for ice cores that aim to extend the ice core record to the last 1.5?Myr, i.e., across the Mid-Pleistocene Transition…

The Effect of Past Saturation Changes on Noble Gas Reconstructions of Mean Ocean Temperature Geophysical Research Letters, 2023 (Ref: 16752)
