<>Does anyone have any idea how this extra heat and volume will dissipate ?
Probably not but as we're on the cusp of the freezing/melting season here are some options....
1. It's a 'one off' that slowly fades away by mixing, adding to general AGW.
2. It's perennial and layer thickness and temperature increase yearly, eventually warming surface layer and reducing ASI.
3. Without the thick ice 'governor' the gyre spins up to unstable speed, the freshwater layer slips off into the CAB at the end of the melting season and freezes in place up to 20m thick. The warm layer radiates into space in clear skies and gives us another 10 years to save the planet. Marvel make a film about it.

didn't mean to imply your ideas were wild Bruce Steeleedit: incoming from bering/chukchi or upwelling?
