What was the air temperature and wind speed when you took that video?Weren't you nervous about falling in?
Temperatures were about 28 degrees F (WARM!) and wind 0 mph!The ice we walk on, most of the time, is about 2 meters thick! That's thicker than Mr Morgan is tall! So we don't worry too much about falling in. Where the pup is playing in the slush, it is a place where a small crack has let sea water from the ocean below up and on top of the ice, making the slush pool. So even though it looks like I am filming from the slush pool, I'm not, I'm standing on solid ice next to the slush pool.Living and working on the ice can be a little frightening at first, but once you get used to it, and figure out that, even though there is a huge amount of water below you, the ice is thick enough that you don't have to worry most of the time! BUT, we only walk on ice when we absolutely know that it is thick enough to support our weight.
That's how I wake up in the morning from under my blanket.
