Could this be an arctic sculpin?

I was wondering if somebody can definitely identify this species. We encountered it while diving in North-East Greenland. Water temperature was about a few degrees C. It was in relatively shallow water (about 6 meters) lying on the bottom.

All suggestions are welcome.

Our diveguide had the feeling it was an arctic sculpin.

This is in norwegian, an 'ulke'.

Can provide real name tomorrow

Very common here.

I have the feeling that means it is a sculpin. I tried to google "ulke" and got several fish amongst which some sculpins. But if you can give me the "real name" that would be very much appreciated.
