AMOC Modulates Ocean Heat Content During Deglaciations
GEOPHYSICAL RESEARCH LETTERS
26 march 2025
Markus Grimmer, Daniel Baggenstos, Hubertus Fische...
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 me...
The role of AMOC variations on the rapid increase of atmospheric CO2 at the onset of interglacial MIS9

ADVANCES IN UNDERSTANDING THE CAUSES, MECHANISMS, AND IMPACTS OF QUATERNARY ABRUPT CLIMATE CHANGES AND THEIR IMPLICATIONS FOR THE FUTURE I ORAL
paleoceanography and paleoclimatology | 13 december 2024
Kathleen Wendt, Christoph Nehrbass-Ahles, Kyle Nie...
The last glacial period was punctuated by cold intervals in the North Atlantic region that culminated in extensive iceberg discharge events. These col...

The Effect of Past Saturation Changes on Noble Gas Reconstructions of Mean Ocean Temperature
GEOPHYSICAL RESEARCH LETTERS
21 march 2023
Frerk Poppelmeier, Daniel Baggenstos, Markus Grimm...
The ocean's immense ability to store and release heat on centennial to millennial time scales modulates the impacts of climate perturbations. To ga...
High-resolution measurements of δ13C-CH4 reveal heavy anomalies during enhanced CH4 emissions associated with Heinrich Events
ICE CORE RECORDS OF ENVIRONMENTAL CHANGE I POSTER
cryosphere | 14 december 2022
Ben RiddellYoung, Edward J. Brook, James E. Lee, J...
Past abrupt millennial scale changes in atmospheric methane (CH4) are linked to similarly dramatic changes in Northern Hemisphere climate known as Dan...
