Crowdsourced facts on sea ice for newcomers and people wanting to learn more
« on: July 22, 2020, 06:46:56 PM »
I saw that many of us didn’t know about certain aspects of the ice which makes it difficult to have a conversation with shared knowledge, I propose that we do fact summaries on those many areas of knowledge on sea ice.

That would be about ice creation and melt processes, atmospheric circulation and weather in the Arctic, ice melt effects, sea ice and oceanic currents, feedback mechanisms...

Edit: thanks to Oren we have a new modus operandi, the top half of a dozen posts are would be articles and you can post any info on any of these topics below, preferably mentioning which one you are talking about, which Oren will edit into the articles. If you see any topic or subject missing you’re more than welcome to highlight it and we’ll incorporate it into the skeleton of one of our articles.
All info should be backed by reputed sources, preferably peer reviewed.
Hope this works and leaves us all a bit wiser than we were.

After a thousand steps on the ice, it cracked.
The Man looked down at the infinite blue of the sea.
On the horizon, standing still, the polar bear had just scented his next meal.

 Less than 3000 cubic kilometers this Piomas minimum.

Great idea, although some subjects may find disagreements. This can work like the glossary, users submit aryicles and corrections and I edit them into the top post.

Thanks a lot ajouis. Now all we need is knowledgeable people to start writing these articles or parts of them.

agreed, there is only a couple subjects I can even touch on, I will message some of the more knowledgeable posters to see if they are interested in contributing
