    Description: Proximal evidence of the surface ocean response to the size reduction of the Greenland Ice Sheet (GIS) during the Last Interglacial (MIS5e) and preceding glacial termination (T2) remains largely elusive. Using a new sediment record from the western Iceland Sea, the behavior of the northeastern GIS and its relation to the (subpolar) North Atlantic surface hydrography is examined. Extremely light oxygen isotopic (delta18O) values are found off central East Greenland during early MIS5e and point to enhanced meltwater release, potentially from the northeastern sector of the GIS. Data from downstream the cold East Greenland Current (EGC) and its eastward branches suggest a far-reaching effect of this meltwater not only in the Nordic Seas but also in the SE Labrador Sea. In particular, whereas an early MIS5e warming (at ~128.5-126.5 ka) in the two regions coincided with the relative reduction of meltwater input into the EGC, the subsequent cooling noted at ~126.5 ka followed a renewed major freshwater event off central East Greenland. Our data further indicate persistent freshwater influence from the East Greenland margin over the entire MIS5e interval and, in addition, also reveal a late MIS5e meltwater event. The latter event occurred just prior to the last glacial inception and emphasizes the importance of Greenland meltwater as forcing factor on Interglacial climates.

    Description: Sediments of the Arctic Ocean are recorders of oceanographic and climatic evolution in the northern hemisphere, The sedimentary history is reflected in the sediment physical properties, thus knowledge about them is a key to its Interpretation particularly within the Quaternary. In this study, 29 sediment cores from the eastern Arctic Ocean were investigated On porosity, wet bulk density and ten cores on compressional (P-) wave velocity. Analysis of these parameters permits interpretations about the sedimentary conditions in the Amundsen and Makarov Basins and on the Lomonosov Ridge, Yermak Plateau and Morris Jesup Rise. The distribution of 25 sediment cores throughout abyssal hill and abyssal plain locations of the eastern Arctic Ocean show specific distribution patterns of wet bulk densities and porosities which characterize the sedimentary regions. On the Yermak Plateau undisturbed pelagic sedimentation predominates. The Lomonosov Ridge and the Morris Jesup Rise are characterized by winnowing. On the Gakkel Ridge turbidite and ice transported deposits are dominant. With the exception of turbidite layers in the Amundsen Basin and ice transported sandy layers in the Makarov Basin, sediments of these basins are dominated by fine-grained sediment. ff...

    Description: The Last Interglacial in the Arctic region is often described as a time with warmer conditions and significantly less summer sea ice than today. The role of Atlantic water (AW) as the main oceanic heat flux agent into the Arctic Ocean remains, however, unclear. Using high-resolution stable isotope and faunal records from the only deep Arctic Gateway, the Fram Strait, we note for the upper water column a diminished influence of AW and generally colder-than-Holocene surface ocean conditions. After the main Saalian deglaciation had terminated, a first intensification of northward-advected AW happened (~124 ka). However, an intermittent sea surface cooling, triggered by meltwater release at ~122 ka, caused a regional delay in the further development towards peak interglacial conditions. Maximum AW heat advection occurred during late MIS 5e (118.5-116 ka) and interrupted a longer-term cooling trend at the sea surface that started from about 120 ka on. Such a late occurrence of the major AW-derived near-surface warming in the Fram Strait - this is in stark contrast to an early warm peak in the Holocene - compares well in time with upstream records from the Norwegian Sea, altogether implying a coherent development of south-to-north ocean heat transfer through the eastern Nordic Seas and into the high Arctic during the Last Interglacial.
