Maybe he'd find a hidden tribe that has been protected by a local water spirit, and he has to help them deal with some threat to their water source.
Since he's used to the water, he could seek out natural hot springs in Alaska. These would be his havens. He could also learn from the native Alaskans about how to dress warmly and make the most of the limited daylight during the winter. He'd have to be careful though, as his powers might react differently in the extreme cold, and he'd need to constantly adjust his fighting and survival techniques.

Along the way, he could team up with some local Inuit demigods who have their own unique powers and knowledge of the Alaskan wilderness.
