COASTAL MORPHO-STRATIGRAPHY AND HOLOCENE RELATIVE SEA-LEVEL CHANGES AT TUAPAAT, SOUTHEASTERN DISKO ISLAND, CENTRAL WEST GREENLAND

The geomorphology of a coarse clastic coastal landscape at Tuapaat (69 degrees 24'N 52 degrees 36'W), southeastern Disko Island, central Wes t Greenland, is described, and a coastal morpho-stratigraphy of the la ndscape is constructed. C-14 ages on marine shells, whale bones, pear and gyttja are used to construct relative sea level changes throughout the Holocene. The emergence of SE Disko Island occurred in the early part of the Holocene. The Holocene marine limit is situated ca. 80 m a .s.l. Between 4.7 and 1.0 ka sp, the relative sea level approached the present sea level and it has probably been below present sea level be tween 4.7 ka BP and the present. The morpho-stratigraphy in the lowest part of the coastal landscape at Tuapaat suggests a complex late Holo cene relative sea level history which includes at least 3-4 transgress ions during the last ca. 2.5 ka.
