133. Multi-year ice is the hardest sea ice and should be avoided if possible. It is recognizable because of what tone to its surface color?
Multi-year ice appears bluish due to the loss of air bubbles and brine, which allows light to scatter and create a blue tone. This distinguishes it from younger ice types that appear grey-white, grey, or greenish, and highlights its increased thickness and hardness.
