Sea ice in the Arctic is one of the most rapidly changing components of the global climate
system. Over the past few decades, summer areal extent has declined over 30%, and all …

While there are numerous hypotheses concerning glacial–interglacial environmental and
climatic regime shifts in the Arctic Ocean, a holistic view on the Northern Hemisphere's late …

In this article, we review evidence of how climate change has already resulted in clearly
discernable changes in marine Arctic ecosystems. After defining the term 'footprint'and …

As the planet cooled from peak warmth in the early Cenozoic, extensive Northern
Hemisphere ice sheets developed by 2.6 Ma ago, leading to changes in the circulation of …

We present the first sedimentary biomarker study encompassing the entire Arctic Ocean. A
large data set of organic markers for terrigenous, petroleum and combustion inputs [alkanes …

New sediment cores were recovered along two transects from the Canada Basin across the
central Mendeleev Ridge towards the Makarov Basin and the Lomonosov Ridge in the …

Sediment core HLY0503-8JPC raised by the HOTRAX'05 expedition from the Mendeleev
Ridge was analyzed for multiple lithological, paleontological, and stable-isotopic proxies to …

The Cenozoic ice‐rafted debris (IRD) history of the central Arctic is reconstructed utilizing the
terrigenous coarse sand fraction in IODP 302 cores from 0 to 273 meters composite depth …

A study of three long cores from the outer shelf and continental slope north of Alaska in the
Arctic Ocean indicate that localized drift deposits occur here with sedimentation rates of …

Extensive dirty ice patches with up to 7 kg m− 2 sediment concentrations in layers of up to 10
cm thickness were encountered in 2005 and 2007 in numerous areas across the central …
