Interstadial North Atlantic warming during the last glacial period involved the operation of both fast and slow components of the coupled atmosphere–ocean–sea-ice system, according to analyses from the Portuguese Margin and climate model simulati

Direct proxy evidence for the many explanations for past millennial-scale atmospheric CO2 changes remains scarce. Here, the authors show that changes in the efficiency of respired carbon storage in the deep Southern Ocean were linked to variations in

The Biological Pump During the Last Glacial Maximum

Autor: Luke C Skinner, Eric D. Galbraith

Publikováno v: Annual Review of Marine Science. 12:559-586

Much of the global cooling during ice ages arose from changes in ocean carbon storage that lowered atmospheric CO2. A slew of mechanisms, both physical and biological, have been proposed as key drivers of these changes. Here we discuss the current un

The Fram Strait is the only deep gateway between the Arctic Ocean and the Nordic Seas and thus is a key area to study past changes in ocean circulation and the marine carbon cycle. Here, we study deep

Deep ocean 14C ventilation age reconstructions from the Arctic Mediterranean reassessed

Highlights • Strong ocean stratification in the Fram Strait during the late glacial (33–26 ka). • Breakup of ocean stratification during the LGM (26–20 ka) due to enhanced upwelling. • No extreme aging of >6000 yr in the Arctic Mediterranea
