Minimum distance to calving glacier fronts
The Governor advises all seafarers to keep their distance to calving glacier fronts in Svalbard.
The Norwegian Polar Institute has, on request from the Governor, made a report where the main conclusions are that it is impossible to predict when an ice block will fall, how big it will be and how/ where it will land in the water. To avoid direct hits by ice and the biggest waves, 200m will, according the report, be a reasonable minimum distance. The Governor still points out that 200 m might be too close in certain cases, and that it is the captains' and the tour operators' duty to assess the risk at any visit to a calving glacier front. The minimum safety distance should be increased when visiting glacier fronts in narrow fjords, in shallow fjords and at glacier fronts higher than 40-50 meters. The Governor recommends the use of a rangefinder to assess the distance to the glacier front.
