Open AccessForCenS-LGM: a dataset of planktonic foraminifera species assemblage composition for the Last Glacial Maximum
Species assemblage composition of marine microfossils offers the possibility to investigate ecological and climatological change on time scales inaccessible using conventional observations. Planktonic foramini...

Open AccessStrong temperature gradients in the ice age North Atlantic Ocean revealed by plankton biogeography
The cold Last Glacial Maximum, around 20,000 years ago, provides a useful test case for evaluating whether climate models can simulate climate states distinct from the present. However, because of the indirect...

Open AccessA global synthesis of high-resolution stable isotope data from benthic foraminifera of the last deglaciation
We present the first version of the Ocean Circulation and Carbon Cycling (OC3) working group database, of oxygen and carbon stable isotope ratios from benthic foraminifera in deep ocean sediment cores from the...

Open AccessRyder Glacier in northwest Greenland is shielded from warm Atlantic water by a bathymetric sill
The processes controlling advance and retreat of outlet glaciers in fjords draining the Greenland Ice Sheet remain poorly known, undermining assessments of their dynamics and associated sea-level rise in a war...

Open AccessThe Holocene retreat dynamics and stability of Petermann Glacier in northwest Greenland
Submarine glacial landforms in fjords are imprints of the dynamic behaviour of marine-terminating glaciers and are informative about their most recent retreat phase. Here we use detailed multibeam bathymetry t...

Meridional shifts of the Atlantic intertropical convergence zone since the Last Glacial Maximum
The position of the intertropical convergence zone is thought to be linked to changes in the Earth’s climate state. Analyses of marine sediment show that over the past 25,000 years, the intertropical convergen...

Extraterrestrial 3He as a tracer of marine sediment transport and accumulation
THE deposition rate of deep-sea sediments, and their focused redeposition by deep-sea currents, can be evaluated from analyses of sedimentary 230Th with a temporal resolution limited only by bioturbation6,7,10,11

Oceanic Response to Orbital Forcing in the Late Quaternary: Observational and Experimental Strategies
Observations on deep-sea cores demonstrate that late Pleistocene climate is dominated by three broad-band cycles centered near periods of 23 ky, 41 ky, and 100 ky. These cycles permeate the global system, and ...
