The ocean is the source of all life. With every drop you drink and every breath you take, you are connected to the ocean no matter where on Earth you live. Oceans generate 70% of the oxygen in the air, and absorb much of its carbon dioxide. They drive the climate, the weather and the chemistry of the planet. Our oceans occupy over 2/3 of the planets surface and provide a home for most of the creatures on Earth. Unfortunately, our knowledge of the ocean is far outstripped by our impact on it. Although time is running out, it isn't too late to expand on our understanding of the worlds oceans, and to use that knowledge to effect positive change.

The Sub Marine Explorer was built in New York by Julius Kroehl in the mid-1800s. Kroehl brought his invention to Panama's pearl islands for pearl fishing, but the craft was technically flawed, giving its occupants the "bends" or decompression sickness. It was abandoned near shore in 1865 and was rediscovered in 2001 by archaeologist Dr. James Delgado. In 2008, the Waitt Institute partnered with Dr. Delgado, the Institute of Nautical Archaeology and the Instituto Nacional de Cultura de Panama to complete documentation of the sub before the tides erode its hull into the sea.

Great White Sharks: the most majestic and most misunderstood predator on the face of the earth. A recurring population migrates each fall to Isla Guadalupe to feed on seals, sea lions, and tuna. Known as "apex' predators, these sharks are absolutely critical in maintaining a balanced marine ecosystem, but their future is threatened as their numbers decline due to commercial fishing and poaching.

www.silvertipworld.com - In the freezing waters of Svalbard, beyond 79 degrees north, an unusual predator is feeding on the abundant plankton. This is a type of ctenophore, or comb jelly - the name derives from the hair-like structures running down their length, which are used for movement. This jelly has swallowed an animal called a larvacean, a type of plankton that exists in huge numbers in these waters. This particular meal tries to escape - watch to see what happens!

The waters around Bermuda are warmed by the Gulf Stream, and host the Sargasso Sea--a liquid jungle of creatures such as loggerhead turtles, fish, sea hares, crabs, and seahorses that exists in floating forests of golden brown sargassum seaweed on the surface of the sea. Within Bermuda's deep waters, explorers William Beebe and Otis Barton discovered bioluminescent sea creatures reminiscent of comets, suns and stars. In between the surface and the deep sea, humpback whales and jellies drift along with the ocean currents.

Freeport, Gand Bahama is known for the pods of wild dolphin that frolic in it's waters. It is also known for UNEXSO the Underwater Explorers Society which operates one of the largest one of the largest interactive captive dolphin programs where tourists can get in the water and swim with trained captive dolphin and experience these wonderful gentle creatures in their own element. What is truly unique is that these dolphin are taken out into the open ocean on a daily basis to play with divers and snorkelers but never swim away to escape captivity. It is a testament to UNEXSO and the wonderful care they receive. This video was shot by George Monteiro of Sea-Cam, Inc. on the new Red Digital Cinema camera.

Just off the coast of Monterey Bay is an undersea canyon that ranks among the largest in the world. It supports life from tiny krill to baleen whales who feed on them. The bay is also home to the Humboldt squid, mola mola, seals, orcas -- and giant kelp forests full of sea slugs, sea urchins, octopus, melibe, and sea otters. At the curve of the bay is the Elkhorn Slough, a seasonal estuary rich in birds and marine life. Cannery Row used to be located here at a time when sardines, salmon and halibut were historically overfished, but the waters around Monterey Bay are now a protected marine sanctuary.

A research team led by Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions on the Arctic Ocean seafloor almost 2.5 miles deep. Scientists did not think volcanoes submerged under such intense water pressure were capable of such violent eruptions. Researchers found jagged, glassy fragments of rock (called pyroclastic deposits) spread out over a 4-square-mile (10-square-kilometer) area around a series of small volcanic craters on the Gakkel Ridge, a remote and mostly unexplored section of the mid-ocean ridge, the volcanic undersea mountain chain that wraps around the globe. These are the first pyroclastic deposits we've ever found in such deep water, at oppressive pressures that inhibit the formation of steam, and many people thought this was not possible, said WHOI geophysicist Rob Reves-Sohn, chief scientist of an expedition to the Gakkel Ridge in July 2007. This means that a tremendous blast of carbon dioxide was released into the water column during the explosive eruption.
