CAUTION
Density of soundings does not fully exclude undiscovered shoals.

Surveys are incomplete in the area. Soundings within unsurveyed areas are unreliable. 
We will strongly advise against any navigation in these areas.

Limits of glaciers are subject to frequent change. In front of glaciers going into sea, 
depths at considerable distance can change essentially (many metres) from year to year. 
All navigation must give attention to this.

Due to irregular nature of botton and incomplete surveys, uncharted dangers may exist.
