Sources of these waters may have been the low-latitude eastern Tethys and high-latitude North Atlantic. Changes in intermediate to deep water sources were probably steered by eccentricity-controlled insolation fluctuations. Lower insolation favored the formation of high-latitude deep waters due to positive feedback mechanisms resulting in high-latitude cooling. This led to a displacement of low-latitude deep waters at Blake Nose. Higher insolation reduced intermediate to deep-water formation in high latitudes, yielding a more northern flow of low-latitude deep waters.","descriptionType":"Abstract"},{"description":"Supplement to: Friedrich, Oliver; Herrle, Jens O; Kößler, Peter; Hemleben, Christoph (2004): Early Maastrichtian stable isotopes: changing deep water sources in the North Atlantic?
