How much ice did you have to break through to dive up there in Norway?
As
Tigerman says, it depends on where you are.
- Inland lakes: Up to chainsaw thickness
- Coast: No ice, due to the North Atlantic Drift. Our coastal harbors normally are open all through winter, all the way past the North Cape.
- Fjords: Varying ice thickness. Outer parts: no ice due to warm(ish), i.e. non-freezing coastal water flowing in with the tide. Inner parts: some ice, varying thickness.
The Trondheim fjord where I dive most is generally open throughout the winter, however the innermost part freezes over rather regularly. Myself, I haven't experienced water colder than 3-4°C .
Getting ready for our annual Christmas tree dive (-7°C air, 4°C surface, 7°C bottom):
Post-dive socializing with hot chocolate and a campfire that has burned out (I was a bit late out of the water):
On the boat, on our way to the dive site (-5°C air, 3°C surface, 4°C bottom). Note the snow on the islands in the background:
Out of the water, a little bit cold in a standard neoprene DS with wetgloves:
So why do we do it? Why the ma(so)chism? This is why (not my videos, alas). The viz can be just fantastic at that time of the year, and there's no algal soup in the top layer:
