Alaska in a Nutshell
Alaska offers some of the world's best cold water diving, featuring stunning scenery and spectacular animal sightings above and below the ocean's surface.
Visibility drastically varies depending on divesites. You can expect to see anywhere between 25 - 80 feet. Keep in mind that when visibility is worse, it is due to upwellings of nutrients - which then pulls in the marine life - so not necessarily a bad thing! Currents can be quite strong, so it is best to time your dives during slack tide (which operators will typically do anyways).
Due to all the nutrients in the water, and the lack of pollutants, there is a shocking amount of life up north - contrary to popular belief. Halibut, octopus, rock fish, ling cod, sea lions, spawning salmon, and humpbacks to name a few.
