Kangerlussuaq, Greenland

The Kangerlussuaq fjord (Danish: Søndre Strømfjord) is a marine environment flanked by highly reworked Archean gneisses. The present-day depth varies between a few meters by the Kangerlussuaq airport (SFJ) near uplifted sediments where concretions have been collected to over 300 m where the mouth of the fjord meets the Davis Strait. During the early Holocene, sea level was approximately 40 m above the present-day land surface at the head of fjord in this paleo tidewater glacier environment. Eventually, it experienced relative sea level decline due to isostatic rebound as the Greenland Ice Sheet (GIS) retreated at the end of the Last Glacial Maximum (LGM). This exposed ancient capelin spawing grounds where spawning-induced fish-kills resulted in an assemblage of exceptionally preserved fossils.

Sediments by the airport are elevated glaciomarine deposits which have recently been exposed due to isostatic rebound from the Last Glacial Maximum.
