Sedimentary strata, Quaternary, late to post glacial.
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.
Flat, low topography bedrock outcrop east and west of borehole.
