The glacial freshwater melt in the Arctic will render much of it a dead zone.
Fresh water melt is not only more acidic, but is also lighter, warmer, less saline and because it is warmer, has a vastly reduced oxygen carrying capacity, than the deepwater.
The net result is that the fresh water melt acts much like putting a clear plastic bag over your face. You can see through it, but it will suffocate you to death.
Most of the Arctic will end up as a dead zone.
This is the physics of water.
