TLDR
In this article, the authors present a biomarker record from Ocean Drilling Program (ODP) Site 912, going back to the Pliocene-Pleistocene boundary and indicating that sea ice of variable extent occurred in the Fram Strait/southern Yermak Plateau area at least since about 22 Ma, and support the idea that a combination of IP25 and open water, phytoplankton biomarker data (PIP25 index) may give more reliable and quantitative estimates of past sea ice cover.About:

TL;DR: In this paper, the changes in sea ice are happening faster than models have projected and substantial uncertainties in the exact timing and high interannual variability will remain as sea ice decreases.

The Arctic sea ice biomarker IP25: a review of current understanding, recommendations for future research and applications in palaeo sea ice reconstructions
Simon T. Belt,Juliane Müller +1 more
TL;DR: A review of the use of IP25 as a proxy for sea ice is given in this article, where the authors highlight the importance of rigorous analytical identification and quantification of the IP25, especially if measurements of this biomarker are going to be used for quantitative sea ice reconstructions, rather than qualitative analyses alone.
Journal ArticleDOI
Source identification of the Arctic sea ice proxy IP25.
TL;DR: Chemical and taxonomical investigations suggest that the IP25-containing taxa represent the majority of producers and are distributed pan-Arctic, thus establishing the widespread applicability of the IP 25 proxy for palaeo Arctic sea ice reconstruction.

TL;DR: In the Eurasian sector of the Arctic Ocean, ice-free conditions prevailed in the early Pliocene until sea ice expanded from the central Arctic Ocean for the first time ca.

A Pliocene-Pleistocene stack of 57 globally distributed benthic δ18O records
TL;DR: In this paper, a 53-Myr stack (LR04) of benthic δ18O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm is presented.

A review of sterol markers for marine and terrigenous organic matter
TL;DR: It is indicated that inferences drawn from sterol distributions regarding sources of organic matter must be made with caution and should be supported using other lipid data, and that in ancient sediments and crude oils a high proportion of C 29 steranes need not indicate that most of the organic matter was derived from vascular plants.

Arctic sea ice decline: Faster than forecast
TL;DR: In this paper, a multi-model ensemble mean time series provides a true representation of forced change by greenhouse gas (GHG) loading, 33-38% of the observed September trend from 1953-2006 is externally forced, growing to 47-57% from 1979-2006.

TL;DR: The sequence of extreme September sea ice extent minima over the past decade suggests acceleration in the response of the Arctic sea ice cover to external forcing, hastening the ongoing transition towards a seasonally open Arctic Ocean.

TL;DR: In this article, a set of century and multidecadal-scale observational data of surface air temperature (SAT) and sea ice is used in combination with ECHAM4 and HadCM3 coupled atmosphere-ice-ocean global model simulations in order to better determine and understand arctic climate variability.
