Reconstruction of Holocene patterns of change in a High Arctic coastal landscape, Southern Sassenfjorden, Svalbard

Multidecadal (1960–2011) shoreline changes in Isbjørnhamna (Hornsund, Svalbard)

“…Strzelecki 2011;Zagórski 2011;Zagórski et al 2012Zagórski et al , 2013Sessford et al 2015b;Strzelecki et al 2015), the coast of Isbjørnhamna is a high−energy coast. Low−energy shores are largely developed by terrigenous processes.…”

Terrestrial processes affecting unlithified coastal erosion disparities in central fjords of Svalbard

“…All the field sites are located within nonglacierized zones, that is, all hydrological influence acting directly on the cliffs comes from precipitation runoff, snowmelt and groundwater flow. These are also locations where modern and historical infrastructure are present and in some cases in danger of being lost or damaged by coastal erosion (Johannessen 1997;Flyen 2009;Sessford et al 2015). Climate and permafrost measurements indicate a warming trend that will continue over the next 100 years or more as discussed by Førland et al (2012).…”

“…Recent years have shown that even if fast ice is not present in the fjord during winter months, there is still an ice foot attached to the shoreline, with snow drifts that build on top of it ( Fig. 2d; Sessford et al 2015).…”

“…Sea-ice coverage has declined for the entire Arctic over the past four decades (Førland et al 2009), and Svalbard in particular is known to have lower sea-ice coverage due to the warm Atlantic Waters which flow past the western coast and enter into fjords (Å dlandsvik & Loeng 1991;Nilsen et al 2008). Although the open-water season is longer in Svalbard, wave action does not appear to have as regular or consistent influence on coastal erosion as might be suspected (Ogorodov et al 2010;Sessford 2013;Sessford et al 2015). Automatic camera photographs show that there were no large storm events during the open-water season over the course of this study, suggesting that erosion is mainly caused by terrestrial influences.…”

Glacial isostatic adjustment associated with the Barents Sea ice sheet: A modelling inter-comparison

“…The N05 scenario is constrained using dated ice-marginal The S04 scenario is built using an ice sheet model (based on the conti- '' nuity equation for ice ow) coupled with a model of water-saturated basal sediment deformation and transportation (Siegert et al, 1999;Siegert and Dowdeswell, 2004). Inputs to the ice-sheet model correspond to an initial bedrock topography at 30 ka BP (assumed similar to the present-day topog-!…”
