| Summary: | This paper concerns the sedimentary processes and products associated with four tidewater gla-cier-dominated inlets of the fjord Isfjorden, Spits-bergen: Tempelfjorden, Billefjorden, Yoldiabuk-ta and Borebukta (Fig. 1). The study is based on high resolution acoustic data and sediment cores. About 60 % of the Svalbard archipelago is cov-ered by glaciers, many of which terminate in fjords as tidewater glaciers. Most of the present Svalbard glaciers are referred to as polythermal (Hagen et al. 1993; Hambrey et al. 1999), and many of them surge (Liestøl 1969; Jiskoot et al. 2000). Environmental factors controlling surges are not fully understood, and advances related to surges are not necessarily climatically induced (e.g. Hamilton & Dowdeswell 1996). The inner parts of Isfjorden were deglaciat-ed around 10 14C Kya (thousands of radiocarbon years ago) (Svendsen et al. 1996). During the early and mid-Holocene, the inner parts of Isfjorden were probably not influenced by tidewater gla-ciers (Svendsen & Mangerud 1997).
