Glacial till, glaciomarine diamictites, and ice-rafted detritus found in marine cores collected off the shore of southeast Greenland record multiple Late Cenozoic glaciations beginning in the Late Miocene. Distinct rock assemblages and seismic stratigraphic control correlate the diamictites with glaciation of the southeast Greenland margin. Glaciers advanced to the sea during several intervals in the Pliocene and Pleistocene. North Atlantic glaciation may have nucleated in southern Greenland… 
Seismic evidence for long-term history of glaciation on central East Greenland shelf south of Scoresby Sund
A seismic reflection transect crossing the central East Greenland continental margin south of the Scoresby Sund fjord system provides information regarding the long-term history of expansion and
Glacial-interglacial history of the Skaftafell region, southeast Iceland, 0 5 Ma
Volcanic strata in the Skaftafell region, southeast Iceland, record a sequence of at least 16 glacial and interglacial intervals since 5 Ma. Two composite sections of 2 to 2.8 km thickness have been
Only 5 southern Greenland shelf edge glaciations since the early Pliocene
It is concluded that the first large shelf edge glaciation of southern Greenland did occur prior to the Pliocene warmth epoch and that such extreme GIS expansions may have occur here only 3 times within the past c.

Abstract A seismic stratigraphic study of the Upper Neogene and Pleistocene shelf and deep-sea deposits of Southeast Greenland is presented. The depositional environment was controlled by glacial,
One million years of glaciation and denudation history in west Greenland
This work quantifies systematic variations in denudation rate among different glacial landforms caused by variations in ice thickness across the landscape by applying a novel Markov-Chain Monte Carlo modelling approach to all available paired cosmogenic 10Be-26Al bedrock data from Greenland.
A multimillion-year-old record of Greenland vegetation and glacial history preserved in sediment beneath 1.4 km of ice at Camp Century
The similarity of cosmogenic isotope ratios in the upper-most sediment to those measured in bedrock near the center of Greenland suggests that the ice sheet melted and re-formed at least once during the past million years.
Thresholds for Cenozoic bipolar glaciation
It is found that Oi-1 is best explained by Antarctic glaciation alone, combined with deep-sea cooling of up to 4 °C and Antarctic ice that is less isotopically depleted than previously suggested, which implies that episodic northern-hemispheric ice sheets have been possible some 20 million years earlier than currently assumed and could explain some of the variability in Miocene sea-level records.


Oxygen isotope calibration of the onset of ice-rafting and history of glaciation in the North Atlantic region
We report here that DSDP Site 552A, cored with the hydraulic piston corer on the west flank of Rockall Bank, recovered an undisturbed sequence of alternating white deep-sea carbonate oozes and
Paleotemperature oscillations in the Middle and Late Miocene of the northeastern Pacific.
The paleoclimatic and paleoceanographic history of the Middle and Late Miocene marginal eastern North Pacific has been studied in a north-to-south transect encompassing DSDP Site 173, the Newport
Evidence for massive discharges of icebergs into the North Atlantic ocean during the last glacial period
SEDIMENTS in the North Atlantic ocean contain a series of layers that are rich in ice-rafted debris and unusually poor in foraminifera1. Here we present evidence that the most recent six of these
Isotopic Evidence for Neogene Hominid Paleoenvironments in the Kenya Rift Valley
If hominids evolved in East Africa during the Late Miocene, they did so in an ecologically diverse setting with a heterogeneous environment with a mix of C3 and C4 plants has persisted for the last 15.5 million years.
Chronology of Fluctuating Sea Levels Since the Triassic
An effort has been made to develop a realistic and accurate time scale and widely applicablechronostratigraphy and to integrate depositional sequences documented in public domain outcrop sections from various basins with this chronostratigraphic framework.
Sedimentation on an early Proterozoic continental margin under glacial influence: the Gowganda Formation (Huronian), Elliot Lake area, Ontario, Canada
Eight continuous cores up to 150 m long and spaced an average of 200 m apart yield a detailed local insight into the composition and architecture of an ancient continental margin sequence, the
Northern Hemisphere climate regimes during the past 3 Ma: possible tectonic connections
The 100 ka rhythm of orbital eccentricity has dominated large-amplitude climatic variations in the high-latitude North Atlantic during the Brunhes magnetic chron (0-0.735 Ma BP). Earlier, during the
