A time-series of evolving glacial geomorphology for Esjufjallajökull (Breiðamerkurjökull), southeast Iceland

This paper presents four glacial geomorphology maps depicting glacier retreat and landscape evolution between September 2021 and May 2023 at Esjufjallajökull, the central flow unit of Breiðamerkurjökull, southeast Iceland. The foreland, which deglaciated between 2010 and 2023, was mapped from repeat uncrewed aerial vehicle (UAV) survey data. A total of 16 landform types were identified, and their spatial distribution and morphological evolution provide valuable insights into ice and meltwater dynamics during deglaciation. The time-series reveals spatiotemporal variations in landform assemblages: a buried ice environment characterising the western study area, proglacial lakes, hummocky meltwater tracts and eskers dominating the central zone, and meltwater eroded spillways further east. The maps cover an area ranging from 2 to 5.4 km2, at a scale ranging between 1:4000 and 1:5000. © 2025 The Author(s).
