The mangrove forest is a place of amazement both above and below the waterline. Mangroves have the unique ability to live in salt water, and they use their highly specialized roots to filter salt, inhale oxygen, and extract nutrients from an environment that other trees can not tolerate. The world within the tangled mess of mangrove roots is dark, silty, eerie, and wonderful.
The vast, unexplored ocean is filled with wonderful and mysterious creatures. This week, we journey far offshore for a midnight drift dive with over 1,000 feet of water between us and the seafloor. The animals here are bizarre and beautiful, and little is known about their biology.
One of the most difficult habitats for any organism to inhabit is the intertidal. Wave energy, temperature fluctuations, and salinity changes make living here impossible for all but a few of the hardiest plants and animals. In the 4th episode of our series UnderH2O, we sneak into this mostly unexplored habitat during the short window of time when the tide is out and the tidepools are accessible.
Two miles off the shore of Oahu, a Corsair F4U airplane crashed into the water in the closing months of World War II. The plane is an oasis of life in an otherwise barren desert of sand. The UnderH2O film team dives to a depth of 100 feet to document this fully intact piece of history.
Manta rays are one of nature's most graceful and eerie animals. In Episode 2 of UnderH2O, we go underwater off the Kona Coast of the Big Island of Hawaii -- in the dark of night -- to film these enormous creatures. When conditions are right, manta rays flock to this special area in search of giant mouthfuls of plankton which they scoop up as they spin and loop around the divers.
