My friend Graham runs a company that takes people into the Canadian Arctic to go scuba diving under the ice. Yeah, under the arctic ice. If you ever go on one of these diving trips under the ice, you can see polar bears, seals, narwhal, and walruses. One thing you will not find down there, however, is me swimming around.
Here is a video from one of his recent expeditions where they are actually scuba diving under and around an iceberg that is frozen into the sea ice and grounded. Amazingly, Graham also ice-climbs these grounded icebergs. Pretty c-c-cool.
