More filming today. At nine in the morning we are on a MarViva boat, speeding out of the bay and around to the other side of the island. This boat is smaller and more mobile than the Ranger, larger and more stable than our little dingies, and MarViva has offered to transport the diving team from one site to another.
Miguel (a MarViva captain) steers, Mar watches the water. Every once in a while fins appear momentarily, or something jumps and lands with a splash. For a few minutes we have dolphins at the bow. The marine life at Cocos, even on the surface, is extraordinary -- but in this place it is the norm. The island itself is verdant and wet, quite literally dripping with water; it falls in threads down the island's steep green sides. Some of the waterfalls disappear into the forest. Others have carved long channels from the top of the island down to the sea. Cocos gets 280 inches of rain a year. There is so much water here that the park rangers who work on the island (they rotate month-long shifts) have constructed a hydroelectric dam to power their base.
