“…The Outer Porsanger and preceding Risvik sub-stages are the earliest sub-stages of the last deglaciation in Finnmark; both pre-date the late-glacial interstadial (Greenland interstadial 1) and are dated to ca. 15,000 cal yr BP (Romundset et al, 2011) and ca. 16,000 cal yr BP (Winsborrow et al, 2010), respectively.…”

Abstract: Recent studies have highlighted the dynamic behavior of marine-terminating outlet glaciers over decadal time-scales, linked to both atmospheric and oceanic warming. This helps explain episodes of near-synchronous flow acceleration, thinning and retreat, but non-climatic factors such as subglacial overdeepenings can also induce rapid recession. There is support for these topographic controls on glacier retreat, but there are few long-term records to assess their significance across a population of glaciers over millennial time-scales. Here, we present retreat chronologies alongside topographic data for eight major outlet glaciers that experienced similar climatic forcing during deglaciation of the Fennoscandian Ice Sheet (ca. 18-10 cal. kyr B.P.). Retreat rates averaged over several millennia (~30 m a-1) are less than half those recently observed on modern-day outlet glaciers (>100 m a-1), but deglaciation was punctuated by episodes of more rapid retreat (up to ~150 m a-1) and re-advances. Significantly, phases of rapid retreat were not synchronous between glaciers and most occurred irrespective of any obvious atmospheric warming. We interpret this to reflect the complex interplay between external forcing and both topographic (e.g., bathymetry, width) and glaciological factors (e.g., ice catchments) that evolve through time, but conclude that basal over-deepenings in wide fjords induce episodes of rapid retreat (>100 m a-1), further exacerbated by their greater susceptibility to oceanic warming. This complicates attempts to predict the centennial-scale trajectory of outlet glaciers and suggests that modeling the interaction between neighboring catchments and the accurate description of subglacial topography beneath them is a priority for future work.Response to Reviewers: See attached cover letter and response to reviewer comments Powered by Editorial Manager® and ProduXion Manager® from Aries Systems CorporationPublisher: GSA Journal: GEOL: Geology Article ID: G35299 Recent studies have highlighted the dynamic behavior of marine-terminating 11 outlet glaciers over decadal time-scales, linked to both atmospheric and oceanic warming. 12This helps explain episodes of near-synchronous flow acc...

“…A gradual lowering of the sea level (∼10 m between 6.0 and 2.5 ka BP) in the area (Romundset et al . ) probably resulted in a more restricted AW exchange compared to the early Holocene (López Correa et al . ) and may have had the effect that bottom‐water temperatures became more susceptible to atmospheric changes compared to the early Holocene.…”

A high-resolution record, covering 9.3-0.2ka BP, from the sub-arctic Stjernsund (70 degrees N) was studied for benthic foraminiferal faunas and stable isotopes, revealing three informally named main phases during the Holocene. The Early- to Mid-Holocene (9.3-5.0ka BP) was characterized by the strong influence of the North Atlantic Current (NAC), which prevented the reflection of the Holocene Climatic Optimum (HCO) in the bottom-water temperature. During the Mid-Holocene Transition (5.0-2.5ka BP), a turnover of benthic foraminiferal faunas occurred, Atlantic Water species decreased while Arctic-Polar species increased, and the oxygen isotope record showed larger fluctuations. Those variations correspond to a period of global climate change, to spatially more heterogeneous benthic foraminiferal faunas in the Nordic Seas region, and to regionally diverging terrestrial temperatures. The Cool Late Holocene (2.5-0.2ka BP) was characterized by increased abundances of Arctic-Polar species and a steady cooling trend reflected in the oxygen isotopes. In this period, our record differs considerably from those on the SW Barents Sea shelf and locations farther south. Therefore, we argue that regional atmospheric cooling triggered the late Holocene cooling trend. Several cold episodes centred at approximate to 8.3, approximate to 7.8, approximate to 6.5, approximate to 4.9, approximate to 3.9 and approximate to 3.3ka BP were identified from the benthic foraminiferal faunas and the 18O record, which correlated with marine and atmospherically driven proxy records. This suggests that short-term cold events may result from reduced heat advection via the NAC or from colder air temperatures
