Is the Arctic already ice-free during summer? Not an expert in this field but I'm just curious as to how accurate the Google Map is here

Also, from the interview with scientist Peter Wadhams, his estimate seems to be spot-on.

I still remember, as a kid, we used to draw a white landmass when illustrating the Polar North. Now, I think we'll have to teach the kids to draw wavy lines, representing the Arctic Ocean instead!
You can follow the sea ice extent here at http://polarportal.dk/en/sea-ice-and-icebergs/

There is a lot of things you can not see in regular maps as they fill in the area with ice as open sea on their products,It is the same for land areas too they do not change the maps if the ground is covered by snow.

So the answer to your question,There is still an ice cover in the arctic even if it is starting to get dangerously low at the end of summer.

As a side note it does look like the arctic ice cover is melting a lot faster this year than what it have done the last ten years on average,You can see a more detailed and year by year graph here https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/ for both arctic and antarctic sea ice
