Scientists call for new stewardship of the deep ocean: Earth's last frontier
Date:2/16/2014

The deep ocean, the largest domain for life on earth, is also its least explored environment. Humans are now encroaching more vigorously than ever into the ocean's deep regions, exploiting the deep's resources and placing its wealth of vibrant habitats and natural services for the planet at risk.

Lisa Levin, a biological oceanographer at Scripps Institution of Oceanography at UC San Diego, believes the vital functions provided by the deep seafrom carbon sequestration to nurturing fish stocksare key to the health of the planet. As humans ramp up exploitation of deep-sea fish, energy, minerals, and genetic resources, a new "stewardship mentality" across countries, economic sectors, and disciplines is required, Levin says, for the future health and integrity of the deep ocean.

Levin and several other experts will describe this need during "Deep-Ocean Industrialization: A New Stewardship Frontier" at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago at a news briefing (noon, Central Standard Time, Sunday, Feb. 16, AAAS Newsroom Headquarters: St. Gallen 2 room, Swisstel, 323 East Upper Wacker Drive, Chicago, Ill. 60601) and scientific presentation (1:30-4:30 p.m. CST, Sunday, Feb. 16, Columbus EF at the Hyatt Regency Chicago, 151 East Wacker Drive, Chicago, Ill., 60601).

As the human population has more than doubled in the past 50 years, demand for food, energy, and raw materials from the sea has risen with it.

"At the same time, human society has undergone tremendous changes and we rarely, if ever, think about these affecting our ocean, let alone the deep ocean," said Levin, who has conducted research on the deep sea for more than 30 years. "But the truth is that the types of industrialization that reigned in the last century on land are now becoming a reality in the deep ocean."

"As we exhaust many coastal stocks, commercial fishers have turned towards deeper waters," said L
