Correlations between climate records from North Atlantic sediments and Greenland ice
OXYGEN isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations—called Dansgaard–Oeschger events—punctuated the last glaciation1. Here we present records of seaExpand
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 theseExpand
Redfield ratio based on chemical data from isopycnal surfaces
The composition of the organic matter oxidized within the thermocline of the Atlantic and Indian oceans has been estimated from the chemical data along the σθ 27.0 and 27.2 horizons. These estimatesExpand
Gas exchange rates between air and sea
Gas exchange rate studies carried out in the laboratory suggest that the stagnant film model is adequate to relate the transfer coefficients of most gases between the atmosphere and sea to anExpand
Interhemispheric Atlantic seesaw response during the last deglaciation
TLDR
New records from the South Atlantic are presented that show rapid changes during the last deglaciation that were instantaneous (within dating uncertainty) and of opposite sign to those observed in the North Atlantic. Expand
PALEOCEAN CIRCULATION DURING THE LAST DEGLACIATION : A BIPOLAR SEESAW ?
Hughen et al. [1998] have documented that during the first 200 years of Younger Dryas time the 14C content of atmospheric CO2 increased by ∼50‰ and that during the remainder of thisExpand
The Peru Upwelling and the Ventilation of the South Pacific Thermocline
A reconstruction of the prebomb A 14C distribution in the tropical Pacific using data from old coral heads shows that surface waters with the lowest A14C content are found distinctly south of theExpand
Routing of meltwater from the Laurentide Ice Sheet during the Younger Dryas cold episode
ROOTH1 proposed that the Younger Dryas cold episode, which chilled the North Atlantic region from 11,000 to 10,000 yr BP, was initiated by a diversion of meltwater from the Mississippi drainage toExpand
Does the ocean–atmosphere system have more than one stable mode of operation?
The climate record obtained from two long Greenland ice cores reveals several brief climate oscillations during glacial time. The most recent of these oscillations, also found in continental pollenExpand
Massive iceberg discharges as triggers for global climate change
Observations of large and abrupt climate changes recorded in Greenland ice cores have spurred a search for clues to their cause. This search has revealed that at six times during the last glaciation,Expand
