Diving in the Marshall Islands with tuna, turtles and wrecks

It was clear right away it was a tuna swimming past because of the distinctive bumps along its back that lead to its angular tail. And what a whopper. It was about the size of a small person, and seemed unbothered by me bobbing just a few feet away.

It was my second dive, with a colleague, in the remote Marshall Islands, located midway between Hawaii and Australia. There's little tourism here, but plenty to see below the surface. During our first dive, in the Majuro lagoon, we'd explored a sunken plane, helicopter and ship in water that was warm and crystal clear.

We started with the plane, an old DC3 that was resting on the sandy bottom at a shallow depth of between 3 and 6 meters, making it accessible for novice scuba divers and even experienced snorkelers.
