Preliminary investigation of a method for determining past winter temperatures at Ellis Fjord, eastern Antarctica, from fast-ice diatom assemblages

The abundance of diatoms from the fast-ice mat community in sediment assemblages from the fjords of the Vestfold Hills has the potential to provide a proxy record of average winter temperature. Fast-ice cover on the fjords determines the proportion of diatoms from the fast-ice mat community in the s...

Description
Summary:The abundance of diatoms from the fast-ice mat community in sediment assemblages from the fjords of the Vestfold Hills has the potential to provide a proxy record of average winter temperature. Fast-ice cover on the fjords determines the proportion of diatoms from the fast-ice mat community in the sedimentary diatom assemblages. ANARE expeditioner records demonstrate a tentative relationship between fjord ice cover and average winter temperature. Short cores from Ellis Fjord, Taynaya Bay and Nella Fjord show fluctuations in the proportion of fast-ice diatoms but so far it has not been possible to correlate these with historical records.
