Studies report on changes of Norwegian glaciers
Journal of Glaciology has used a historical map from 1902 of the Østre Svartisen ice cap as cover image. See the full cover here.
A new issue of Journal of Glaciology includes two papers by NVE authors on glacier changes in Norway.
Glacier change in Norway since the 1960s:
This paper gives an overview of changes in area, length, surface elevation and mass balance of glaciers in mainland Norway since the 1960s. More than half of the observed glaciers, 27 of 49, had marked advances in the 1990s. The glaciological mass-balance values for the period 1962–2018, where 43 glaciersmhave been measured, show great inter-annual variability. The results reveal accelerated deficit since 2000, the most negative decade being 2001–2010.

Historical maps used to assess the ~1899 glacier extent of the Nordland county:
This study reconstructs the ∼1899 (covering the period 1882–1916) glacier extent in Nordland, northern Norway, from historical gradteigskart maps, with an emphasis on examining the accuracy of the mapped glaciers. This work is part of Paul Weber's ph.d. work (University of Poursemputh/UK).

A popular paper in Norwegian on the use of historical map series 'Gradteigskart' was published in Aftenposten in October 2019:
