Absolute and relative errors on altitude measurements are considered to be respectively ± 0.5 m and less than ± 0.2 m.Figure 3: Topographic profiles of the western (A), the middle (B) and the eastern (C) cuspate forelands at Saqqarliit Ilorliit.
The coastal geomorphology of three cuspate forelands at Saqqarliit Ilorliit, western Disko, West Greenland is described, sediment core data from salt marshes and lagoons are presented, an emergence curve is constructed, and data are discussed in relation to late Holocene relative sea-level (RSL) changes. The coastal geomorphology at Saqqarliit Ilorliit suggest transgression early in the interval 2.5 -1.0 ka BP and between 0.7 ka BP and the present.
On western Disko, falling RSL in early-middle Holocene was followed by rising RSL in late Holocene. The first transgression resulted in formation of an intertidal platform and coastal cliffs.
The inner part of the fiord is a good natural harbour even during severe storms. The sea in Akulliit is usually frozen from the middle of December to the beginning of June.
Akulliit has semi-diurnal mixed tide with a spring tidal range of c. A geomorphological map of the coastal zone at Saqqarliit Ilorliit was prepared from field-checked air photo interpretation (Fig. Altitudes of landforms were measured along profiles (Figs.
