I've found the NOAA snow and ice charts to be pretty interesting, especially as a New Zealander I underestimated just how long snow and ice persisted in the northern US and Canada. It's kind of fun to watch an animation of a few years as the snow accumulates then retreats.

Now for a pretty basic question: Canada's Hudson Bay seems to freeze over after snow has accumulated in the surrounding latitudes, but much ice remains for quite a long time after the last snow at similar latitudes has melted. Why is this? Is it simply a matter of the depth of the water making the ice thick enough that it takes a long time to fully melt? Like would a giant frozen puddle melt at a similar rate to snow? Or are salinity and/or physical properties of ice versus snow major factors?

Mass. The mass of ice that has to melt is far greater than that of the snow. Albedo also plays a role. On land, bare patches that show up in late spring quickly accelerate the melt of the remaining snow. On the Bay, a lot of ice has to melt for high-albedo open water to be exposed.

Northern Hemisphere snow cover now at record high levels.
Record Low is because of Global warming. Record High is because of climate change. Dont be a Dope. Weather and climate has always been cyclical on small and long term scales.
