Deglaciation and palaeoclimate of the Andfjord‐Vågsfjord area, North Norway
This paper reviews the deglaciation history and palaeoclimate from 22 to 9.5 14 Cka BP in the Andfjord‐Vagsfjord area. Eight main glacial events are recorded: The Egga‐I (>22 14 Cka BP), the Bjerka, the Egga‐II (>14.6 14 Cka BP), the Flesen (14.5 14 Cka BP), the D (13.8–13.2 14 Cka BP), the Sk...

| Summary: | This paper reviews the deglaciation history and palaeoclimate from 22 to 9.5 14 Cka BP in the Andfjord‐Vagsfjord area. Eight main glacial events are recorded: The Egga‐I (>22 14 Cka BP), the Bjerka, the Egga‐II (>14.6 14 Cka BP), the Flesen (14.5 14 Cka BP), the D (13.8–13.2 14 Cka BP), the Skarpnes (12.2 14 Cka BP), the Tromsø–Lyngen (10.7–10.3 14 C ka BP) and the Stordal (10.0–9.5 14 Cka BP). Onset of the final deglaciation occurred about 14.6 14 Cka BP. Most of the western part of the Fennoscandian and Barents Sea Ice Sheets receded from the outer continental shelf 15–14 14 Cka BP. The delivery and melting of icebergs at this time to the Norwegian‐Greenland Sea resulted in a low oxygen isotope event recorded in a number of cores in the region. Atlantic water intruded the area 13.2 14 Cka BP, and an atmospheric warming commenced 12.9/12.8 14 Cka BP. A marked glacial recession occurred before the Skarpnes event. During Allerød time, the glaciers retreated to the fjord heads or even farther inland. The Fennoscandian outlet glaciers readvanced (locally more than 40 km), reached their Younger Dryas outer limit after 10.7 14 Cka BP and retreated from this position before about 10.3 14 Cka BP. |
