Panel to Discuss Deep-Sea Mining at AAAS Meeting

Home to an immense diversity of marine life, the deep ocean also contains valuable minerals with metals such as nickel, copper, cobalt, manganese, zinc, and gold, and rare-earth elements used in electronic technology like smart phones and medical imaging machines. As demand for these resources increases and supplies on land decrease, commercial mining operators are looking to the deep ocean as the next frontier for mining.

Coral Gardens in the Dark Depths

The words “coral reefs” conjure up images of a tropical paradise: shallow, warm, aquamarine waters, bright sunlight, white coral sand, and colorful, darting fish. But corals also live deep in the sea, in regions where the sun doesn’t penetrate and water temperatures remain just above freezing.

Scientists Find Active Underwater Volcano East of Samoa

Marine geologists from the Woods Hole Oceanographic Institution (WHOI) and the Scripps Institution of Oceanography (SIO) have confirmed the existence of an active underwater volcano east of Samoa. The volcano, recently named VailuluA?u by local students, is located about 28 miles east of TaA?u Island and rises more than 16,400 feet from the seafloor to within 2,000 feet of the ocean surface. The scientists found billowing “smoggy” water in the summit and extending out for more than five miles.

Active 14,000 Foot Submarine Volcano Found near Samoa in South Pacific

An active volcano rising more than 4,300 meters (over 14,100 feet) from the ocean floor in the Samoa Islands has been discovered by a team of U.S. scientists, providing more evidence to the scientific debate over the formation of hot spot island chains. The volcano, more than 35 kilometers (about 22 miles) across at its base, rises to within 600 meters (about 2,000 feet) of the surface; its peak is marked by a circular caldera some two kilometers (over 1 mile) across and 400 meters (1,300 feet) deep. It is similar in size to Mt. Whitney in California, the largest mountain in the contiguous 48 U.S. states.
