A major change in the North Atlantic pattern of ice-rafting deposition, during the last interglacial-glacial cycle, occurred approximately 75,000 B.P. Prior to this time, deposition for a period of almost 50,000 yr during isotopic stage 5 was greatest in the northwest near Greenland and Newfoundland. The main glacial pattern was very different; the main depositional axis shifted abruptly to a zonal axis along lat 46° to 50°N, reflecting the passage of ice farther from the pole before reaching…

Ice-rafted evidence of long-term North Atlantic circulation
Abstract The absolute and relative rates of deposition of ice-rafted volcanic and terrigenous clastic material were determined for the interval from the base of oxygen isotope stage 5 (∼ 127,000 yrs
Patterns of Ice-Rafted Detritus in the Glacial North Atlantic (40–55°N)
The observation by Heinrich (1988) that, during the last glacial period, much of the input of ice-rafted detritus to the North Atlantic sediments may have occurred as a succession of catastrophic
Freshwater influx, hydrographic reorganization and the dispersal of ice‐rafted detritus in the sub‐polar North Atlantic Ocean during the last deglaciation
A sediment core from the north-east North Atlantic contains high-resolution co-registered foraminiferal δ18O and ice-rafted detritus (IRD) records for the last deglaciation. These reveal a distinct
Evolution and demise of the Last Interglacial warmth in the subpolar North Atlantic
Detailed faunal, isotopic, and lithic marine records provide new insight into the stability and climate progression of the last interglacial period, Marine Isotope Stage (MIS) 5, which peaked
Evidence for regional cooling, frontal advances, and East Greenland Ice Sheet changes during the demise of the last interglacial
Abstract High-resolution lithic and sea surface climate records are used to portray the progression of North Atlantic climate, hydrography, and Greenland Ice Sheet (GIS) activity through the peak of
A reconstruction of sea surface warming in the northern North Atlantic during MIS 3 ice-rafting events
Marine isotope stage 3 (29–59 kyr BP) is characterised by rapid shifts from cold stadial to warm interstadial periods, which may be linked to changes in the vigour of the Atlantic Meridional
An alternative suggestion for the Pliocene onset of major northern hemisphere glaciation based on the geochemical provenance of North Atlantic Ocean ice-rafted debris
Abstract The onset of abundant ice-rafted debris (IRD) deposition in the Nordic Seas and subpolar North Atlantic Ocean 2.72 millions of years ago (Ma) is thought to record the Pliocene onset of major
Reorganization of the North Atlantic Oscillation during early Holocene deglaciation
Laurentide ice-sheet retreat continued into the mid-Holocene. Speleothem-based precipitation records suggest the cessation of melt led to the establishment of the present precipitation patterns
Oceanic evidence for the mechanism of rapid northern hemisphere glaciation
Abstract The oxygen isotopic stage 5/4 boundary in deep-sea sediments marks a prominent interval of northern hemisphere ice-sheet growth that lasted about 10,000 yr. During much of this rapid ice
Rapid ice-sheet growth and initiation of the last glaciation
Abstract Calculations based on temperature-corrected oxygen-isotope ratios from deep-sea cores yield a glacioeustatic sea-level fall in excess of 50 m during the first 10,000 yr of the last


Time-transgressive deglacial retreat of polar waters from the North Atlantic
Abstract A 9300 yr-old zone of disseminated volcanic ash in North Atlantic sediments between 45° N and 65° N provides a time-synchronous reference layer against which we have compared the
Glacial marine sediments from the northeast Pacific
ABSTRACT Pleistocene sediments of glacial marine origin have recently been cored within Cascadia Basin in the northeast Pacific Ocean as far south as 44°10N. A uniform distribution of sand grains and

Abstract Eight cores taken on the eastern flank of the Mid-Atlantic Ridge from 3°N to 60°N document climatic shifts over the last 225,000 years. Southward penetration of polar water elimiontated the
Glacial and Quaternary geology
The North America landscape north of about 40°N was extensively glaciated during the last Ice Age, which ended about 14,000 years ago. Thus, much of the landscapes that we see around us was created
