Figures & Tables

Orthophotomap of the study area with nine aeolian deposition test sites (1–9) located within the Ebba Valley. Weather stations (E – Ebba Valley, S – Sven Glacier, and P – Pyramiden city) are marked with black stars. Orthophotomap source – Norwegian Polar Institute. Inner map shows the location of the study area (black arrows and circle) in the central Spitsbergen, High Arctic.

Geomorphological sketch of the study area (Ebba Valley, Svalbard). Modified after the original figure by Rachlewicz (2009).
