Furthermore, following publication of the Greenland Ice Core Chronology 2005 (GICC05)[4] for theNorth GRIPice core, it became clear thatDansgaard–Oeschger events also show no such pattern.[2][5][6] The North Atlanticice-rafting events happen to correlate with episodes of lowered lake levels in the Mid-Atlantic region of the United States,[7] the weakest[clarification needed] events of theAsianmonsoon for at least the past 9,000 years,[8][9] and also correlate with most aridification events in theMiddle East for the past 55,000 years (bothHeinrich and Bond events).[10][11]
Most Bond events do not have a clear climate signal; some correspond to periods of cooling, but others are coincident with aridification in some regions. Gap between events has been estimated to be 1,000-1,500 years[2][1] with Bond event # 4 as anoutlying data point.
Holocene 18O and deuterium derived from ice records in Sajama, Huascarán and Illimani. Arrows showing the temperature drops that could be related to Bond events.
Bond events have been detected in remote regions such as the centralAndes of South America.[18] Up to six Bond cycles during the upper and middleHolocene have been identified in three ice core records of the tropical Andes. The records were extracted from the summits ofNevado Sajama,Nevado Huascarán andNevado Illimani. The detected cycles were at 6400 years Before Present, 5500 years B.P., 3700 years B.P., 2700 years B.P., 1300 years B.P. and 200 years B.P. and represented temperature drops.
