The electronic maps were updated in June and the new paper maps were printed Sept. 8.
"In particular, along the land between Hotellneset and Barentsburg there is new information," said Kjetil Wirak, an official in the map production section for The Norwegian Mapping Authority. "We also received data from the polar institute about all the glacier fronts, so they are aligned."
He said the sea measurements revealed new shallows between Adventfjorden and Barentsburg.
The maps have also updated data from the middle of Isfjorden, but since it is so deep there that has no practical significance.
There are two maps that now come in new editions. The sea chart for Isfjorden and Isfjordrenna, the area from Barentsburg to Prins Karls Forland. Many of the changes in the Isfjorden map are based on measurements the mapping authority made between Adventfjorden and Barentsburg last year.
This year there were measurements in Dicksonfjorden and Ekmanfjorden, but Wirak cannot promise there will also be new maps for there next year.
"New shallows we find we report at that time in notices to mariners," he said. "Commercial traffic is required to update themselves about it. Recreational users can also access the pages of the mapping authority and see such changes."
This year there are about 300 new and altered shallows in Svalbard reported in the system. During the fall, all new shallows from the year's sea mapping voyage will be announced in notices to mariners.
Coming next year
Wirak said the data mappers are coming back next year.
"There is still much to measure in Svalbard," he said. "Especially north and east of Svalbard, there is little surveyed. There it is difficult to get to and there is a lot of ice. It is beginning to be reasonably good on the west coast."
How are areas to be measured chosen?
"We see a bit about the status of the data we have and try to fill the gaps that are missing," he said. "When it comes to Svalbard we must also make plans for the ice and how it is possible to measure. In June we measured on the west coast because of ice in the northeast. What areas we measure also has a background in the suggestions from users."
Last year there were new measurements made from Adventfjorden to Barentsburg. New shallows are plotted in the printed map released this month.
