The first thing is generally the wind.
In some places, you may hear the noise of the generator providing electricity or a snow mobile but there enough space around to avoid those areas if you wish. Princess Elisabeth is more quiet than some other bases as the electricity is produced by windmills and solar panels.
The ice itself is moving so slowly that you did not hear it if you are away from crevasses and ice cliffs that goes to the sea. Even in those regions, the noise is only occurring in some occasions when a movement or a collapse occurs.
This is quite different from the sea ice that floats on the oceans and moves much more quickly. It can be broken by the winds or compressed making ridges, ‘playing’ a complex and sometimes scary music.
There is nearly no life away from the coast so no bird singing or mosquito flying around you.
Consequently, if you are away from buildings and not moving in a windless day, you basically hear nothing during minutes. That is an impressive feeling!
good job
I was there in the late 1960’s with the navy. Most us hated it but had I volunteered as a civilian I might have enjoyed it more. I was a technician and fixed electronic equipment.
