Our cruise to Alaska this year involved traveling over about 1,000 miles of water. Needless to say, the water (average temperature 50F) surrounded our ship. The waters of the Pacific Ocean, the Gulf of Alaska, and the Gulf Islands of Canada changed with the weather and the outflows of rivers and glaciated bays. In Yakutat Bay, near the Hubbard Glacier, the water of the channel showed dramatically different colors where the outflow of glacier water from the melting glacier met the incoming bay and Pacific Ocean water. It’s remarkable how the boundary is so easy to spot.
