This website, https://seaice.uni-bremen.de/sea-ice-concentration/, has fantastic images and movies of the current ice situation in the Arctic (and the Antarctic). They have a sattelite image of the current ice concentrations in the Northwest Passage that are updated every day.

They also maintain a video which shows the last twenty days, and how the ice has been changing in the Northwest Passage. The darker sections are those where the ice is beginning to melt.
