One obvious manifestation of changing climate has been the recent rapid reduction in the extent and volume of Arctic sea ice. However, a dense observational data set spans only a few decades. To better understand sea ice dynamics and especially the context of the recent decline, scientists need to construct longer records. This relies on proxy data from marine sediments, ice cores, and coastal material, each providing evidence of past sea ice presence or absence.
