Along one set of islands, the water was sounding very wet. The first clip below is from above the water as it slurps into crevasses on the rock, and the second is of the same place with my Jez Riley French hydrophone.
Some caves didn’t open up to the lagoon, but curled into the belly of the island. Here is the sound from inside one of those caves.
Outside one cave, monkeys were hanging in the trees. If you look hard in the photo below, you might find one.
