The last couple of days I’ve been discussing sea-ice reconstructions at the Pages Sea-Ice Proxy workshop in Bremerhaven. A huge range of proxies have been presented, ranging from traces of halogens in ice cores to transfer function based reconstructions. One very promising proxy is the annual growth bands of coralline algae. Growth is poor when sea ice cover is high. Many of the presentations have stressed the need to understand the mechanic link between the proxy and sea ice.
That was one of the themes I explored in my presention of some of my work on transfer functions. Rather than dwelling on the problems of autocorrelation and other issues, I focused on the problems identified in Steve Juggins’ “sick science” paper.
My contribution seemed well received. I’ll post it here shortly.
