GP15 passed by Flint Island, an uninhabited coral island approximately 2.5 miles long and 0.5 miles wide. At its highest point it is just 25 feet above sea level.
The surface of the ocean takes on an array of textures and colors depending on the conditions.

An oceanic white-tip shark soars through the water on its broad pectoral fins after the Revelle has been sitting in place for more than 24-hours. As the ship’s shadow collects smaller fish seeking shelter, sharks and other predators come in to investigate. Sadly, the experienced oceanographers on board confirmed that shark sightings are much rarer now than they used to be.
The crystal clear waters of the South Pacific offer a virtually unobstructed view of this oceanic white-tip shark.

Looks like a great leg…I would have enjoyed being there…
