Evaluating the sea ice proxy IPSO25 at the Western Antarctic Peninsula

Sea ice proxies are important tools to reconstruct the climate and environmental history in polar regions. The novel sea ice proxy for the Southern Ocean is the biomarker IPSO25 (Ice Proxy Southern Ocean with 25 carbon atoms), a highly branched isoprenoid (HBI) diene produced by sea ice diatoms. Wit...

Description
Summary:Sea ice proxies are important tools to reconstruct the climate and environmental history in polar regions. The novel sea ice proxy for the Southern Ocean is the biomarker IPSO25 (Ice Proxy Southern Ocean with 25 carbon atoms), a highly branched isoprenoid (HBI) diene produced by sea ice diatoms. With this poster we present the first approach of a sea ice index derived from IPSO25, called PIPSO25, for past sea ice reconstructions in Antarctica.
