Abstract

— The Esjufjallarönd medial moraine separates two branches of the south flowing Breiðamerkurjök-ull outlet of Vatnajökull ice cap, Southeast-Iceland. The more rapidly flowing easternmost branch (Norðlinga-lægðarjökull) descends along a trench, reaching 200–300 m beneath sea level, and calves into the Jökulsárlón lagoon. Recently the rate of calving has increased and a depression has formed in the glacier surface. Hence, inflow of ice toward the eastern branch has led to a lateral shift of the Esjufjallarönd medial moraine bending it eastward by up to 900 m, during the period 2006 to 2016. Thus, the moraine has been shifted by ice flow into the lagoon.
