Sedimentary strata, Quaternary, late to post glacial.
Lithology:
The geology at this site consists of a very thin (few cm) vegetative cover followed by a sequence of late to post glacial marine silty clays. The depth to bedrock is 6.9 m as observed from a borehole at the same location drilled in 1978 in connection with site investigations for the airport. Bedrock is gneiss. Ice content is high in the upper 1 m of the permafrost. Due to a considerable residual salinity, the sediments in the deeper parts of the borehole have large freezing point depressions, rendering the sediments technically unfrozen.
Morphology:
Flat, low topography bedrock outcrop east and west of borehole.
