Although the pulsating nature and abruptness of last deglaciation are well documented in marine land records, very few records have so far been able to capture high‐frequency climatic changes recorded Greenland ice core Dye 3. We studied high‐resolution sediment cores from SE Norwegian Sea, which display a detailed record during comparable that Accelerator mass spectrometry age control enables us correlate this detail with continental records. The results indicate surface waters Sea were...
Eight time slices of surface‐water paleoceanography were reconstructed from stable isotope and paleotemperature data to evaluate late Quaternary changes in density, current directions, sea‐ice cover the Nordic Seas NE Atlantic. We used isotopic records 110 deep‐sea cores, 20 which are accelerator mass spectrometry (AMS)‐ 14 C dated 30 have high (>8 cm /kyr) sedimentation rates, enabling a resolution about 120 years. Paleotemperature estimates based on species counts planktonic...
High‐resolution records from IMAGES core MD95‐2011 in the eastern Norwegian Sea provide evidence for relatively large‐ and small‐scale high‐latitude climate variability throughout Holocene. During early mid‐Holocene a situation possibly driven by consistent stronger westerlies increased eastward influence of Arctic intermediate near‐surface waters. For late Holocene relaxation atmospheric forcing resulted Atlantic water. The main changes show no obvious connection to changing solar...
A continuous 3.5 Myr IRD record was produced from Ocean Drilling Program (ODP) Site 907. timescale based on magnetic polarity chrons, oxygen isotope stratigraphy (for the last 1Myr) and orbital tuning developed. The documents a stepwise inception of large‐scale glacial cycles in Nordic Seas region, first being marked expansion Greenland ice sheet at 3.3 Ma. second step occurred 2.74 Ma by an large scale sheets Northern Hemisphere. Ice variability around tightly coupled to global volume over...
Carbon isotopic records from benthic foraminifera are used to map patterns of deep ocean circulation between 3 and 2 million years ago, the interval when significant northern hemisphere glaciation began. The δ 18 O 13 C data four Atlantic sites (552, 607, 610, 704) one Pacific site (677) show that global cooling over this was associated with increased suppression North Deep Water (NADW) formation. However, relative strength NADW production always greater than is observed during late...
