Content

The archive contains different files. A processed high resolution Geotiff in UTM 33N (1200 dpi), a processed JPG in UTM 33N (300 dpi), the raw Geotiff in WGS84, the used Source SHP File with their secondary files, the “sources map” PDF and the release notes PDF.

The processed UTM 33N Geotiff and JPG are designed for simple and direct usage, while the raw WGS84 Geotiff is for work in different map projections. The original SHP-Files are for work with alternative colour ramps or detailed insight on the used sources and specific reasons for interpolation.

Basic Information

This is map version 1.1. The map extend is defined from 12°W to 44°E and 43°N to 72°N. All Data were digitalised from different sources (See sources map), which are listed further down on this site.

The modern coastline is derived from Natural Earth (https://www.naturalearthdata.com), large lakes were added from the “WISE Large rivers and large lakes” dataset provided by the European Environment Agency (https://www.eea.europa.eu/data-and-maps/data/wise-large-rivers-and-large-lakes). Finally the shaded elevation is calculated on the “GEBCO One Minute Grid” from the “GEBCO Gridded bathymetric Data” (https://www.gebco.net/).  

The maps where produced with QGIS 3.

Source notes

  • Fennoscandian ice sheet data that is not corresponding with Stroeven et al. 2017 was removed and replaced by either water or land areas
  • Coastlines where partially interpolated due to missing data (different ice sheet sizes), based on extrapolation from other sources
  • The British coastline from Brooks et al. 2011 was assumed as the mean value of the 13000 and 10000 BP maps
  • The Bornholm Coast was interpolated with the data from Jakobsson et al. 2007
  • Sea level for the Adriatic sea was set to -45 m a.s.l. based on sea level curve from Moscon et al. 2015
  • Sea level for the Black sea was set to -100 m a.s.l. based on sea level curve from Lericolais 2017
  • The coastlines of Mezen Bay and Kanin Peninsula were interpolated to fit the coast line from Pasanen et al. 2010
  • Minor adjustments were made to smoothen the coastline
