@ninalanyon interesting. I'm realising how Antarctica Ice.. must be sweet water and not sea water.. how did it stay there ? Magnetic field perhaps ? I've never had this question before :)
Thanks for the detailed response 😊

@being Definitely not kept there by magnetic field! I think that Antarctic ice stays put because it is so cold that it just never melts.

Yes, it's fresh water, the Antarctic and Greenland ice sheets have more fresh water than the rest of the planet altogether. But the ice that forms on the fjord is a lot more complicated I suspect. Wikipedia says that sea ice is mostly ice but also contains five to ten percent of brine. But that won't be right for the fjord because there is a lot of fresh water coming down from the river. So the surface water is a lot less salty than the water further down so I imagine that the ice on the fjord will be mostly fresh water.

The polar ice sheets were formed by precipitation though not by freezing sea water.

Time for be, sweet dreams!

@ninalanyon sweet dreams, I'm going too

Thanks for writing all these :))

@turbineman40 Yes. Partly because I don't want to risk over doing things, but also because I don't want to set my expectations too high and then get discouraged. I'm easily discouraged from exercise!

@ninalanyon I agree with you completely on not liking excise
