Ice streams and outlet glaciers are important components of an ice sheet’s mass balance and their behaviour directly impacts on sea level. These corridors of fast-flowing ice have been described as the ‘art eries’ of an ice sheet and their distinction is largely semantic, with ice streams bordered by slower-moving ice and outlet glaciers bordered by expos ed bedrock at the surface. Since the recognition of the importance of these features in the 1970s, there has been a huge growth in their investigation . This began with the pioneering work on West Antarctic ice streams and has subsequently expanded to studies of ice streams and outlet glaciers in all of the world’s major ice sheets and ice masses. Of urgent concern for soci ety are recent observations of dynamic changes in ice streams and outlet gl aciers, which are thought to be responsible for an acceleration in global e ustatic sea-level rise.

In parallel, those studying palaeo-ice sheet beds have long recognized the distinctive geomorphology of ice streams in b oth marine and terrestrial settings. The study of palaeo ice streams offers an unprecedented opportunity to reconstruct their behaviour over time-scal es much longer than modern observations permit, generating new insights int o the spatial and temporal controls on their flow, including longer-term pe rspectives on retreat rates and thinning histories. The beds of palaeo ice streams and outlet glaciers are also more accessible for investigation, lea ding to new insights regarding the mechanisms of sediment erosion, transpor t and deposition beneath fast- flowing ice, including the formation of subg lacial bedforms.

In addition to empirical studies, there have been ma jor advances in our ability to simulate ice-stream and outlet-glacier behav iour in numerical models. Moreover, observations and reconstructions of ice streams/outlet glaciers have provided useful data to test and calibrate nu merical models and recent developments have seen improved projections of ma ss loss.

The aim of this symposium is to bring together scientists wo rking on both modern and palaeo ice streams/outlet glaciers, together with those using numerical modelling, in order to facilitate greater interaction and the cross- pollination of ideas, data and theoretical insight on one o f glaciology’s most important topics.
