Data are used to suggest and discuss a possible sequence of Holocene RSL changes. 3km wide and 25 km long with a maximum water-depth in the fjord of 160 m. Despite the steep fiord sides, depositional shorelines appear frequently along the fiord.
The study area, Saqqarliit Ilorliit, is located in the inner part of Akulliit, which is the middle of three large fiords on western Disko (Fig. The bedrock in the fiord consists of Tertiary basalts. Generally, littoral deposits consist of beach gravel. The wave climate on western Disko is characterized by wind generated waves and swell caused by cyclones in Davis Strait and Baffin Bay.
14 datings of organic carbon in seven lagoon sediment samples (AAR 1810-1816) were carried out on bulk samples using the AMS-technique at the University of Aarhus, Denmark (Heinemeier et al. Errors caused by pre-sampling contamination of bulk samples have been described in details by Mook and van de Plassche(l9B6). The criterias used for the construction of the curve are described in details in the figure text.
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.
Total C and S were determined by combustion in a LECO induction furnace and extractable metals (Ca, Mg, Na, K, Fe and Mn) were analysed using atomic absorption spectrophotometry (AAS).
For metal extraction a simplified successive treatment with concentrated nitric acid and hydrochloric acid, suggested by Bengtsson and Enell (1986), was used to determine the acid-soluble amounts of various elements.
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.
