Episode 102: Mission to Inner Space

Episode Description:

They call it "inner space." It's an inhospitable environment that's difficult to explore and unfit for human habitation. Nevertheless, scientists have figured out ways to live and work on the ocean floor.

The Aquarius Undersea Laboratory is the only underwater operating station in the world today. Located inside the Florida Keys National Marine Sanctuary, at 60 feet below the ocean's surface, this unique facility provides researchers around the clock access to the nearby coral reef. Known as "America's Inner Space Station," the Aquarius Reef Base becomes home to a select few as they spend 10 straight days underwater. During this specific mission, a team of ‘Aquanauts,' or saturation divers, studies the local effects of a global problem, ocean acidification.

Ocean acidification is caused by a change in the water's chemistry. Increased levels of CO2 in the water is leading to lowered pH levels, making it potentially more difficult for organisms like corals to form their calcium carbonate skeletons. This Aquarius mission is unique, in that it is the first ocean acidification study during which aquanauts conduct various experiments and take continuous measurements while living out on a coral reef. What will their findings tell us?

Aquarius Undersea Lab
The Aquarius Reef Base is the world's only undersea laboratory dedicated to marine science. Owned by the National Oceanic and Atmospheric Administration (NOAA) and managed by the University of North Carolina at Wilmington (UNCW), Aquarius provides scientists and others with a unique way to study the ocean.

If Reefs Could Talk
"Six divers live in an unfamiliar habitat 50 feet below the ocean, diving up to nine hours a day to conduct experiments and get a close-up look at Florida's coral reefs — while giving you the chance to travel along!"

National Undersea Research Center (NURC)
NURC maintains six different regional centers of undersea research within the United States. Under the direction of the National Oceanic and Atmospheric Administration (NOAA), the mission of each center is to "direct research towards marine-related issues, provide undersea technology to scientists, and enhance public awareness of the problems and solutions facing our coastal oceans."

NOAA's Undersea Research Program (NURP)
"NURP is primarily an extramural program located at major universities that functions to provide scientists with the tools and expertise they need to investigate the undersea environment, including submersibles, remotely operated vehicles, autonomous underwater vehicles, mixed gas diving gear, underwater laboratories and observatories, and other cutting edge technologies."

The Ocean Acidification Network
This website is a central source for accessing information on topics related to ocean acidification. General ocean acidification data, the latest news, events and research are available on The Ocean Acidification Network.

NOAA's PMEL CO2 Program
The Pacific Marine Environment Laboratory Carbon Dioxide Program conducts ocean carbon cycling research from ships and moorings in all of the major ocean basins. This program monitors changes in ocean carbon chemistry, collects important CO2 data from marine resources and is currently building a network of CO2 moorings to make high resolution time series measurements in the global ocean.

Effects of Climate Change and Ocean Acidification on Living Marine Resources
Woods Hole Oceanographic Institution Senior Scientist Scott Doney testifies before the U.S. Senate Committee on Commerce, Science and Transportation's Subcommittee on Oceans, Atmosphere, and Coast Guard.

Monterey Bay Aquarium Research Institute
This website provides a brief description on the process of ocean acidification as well as an illustration of how carbon dioxide enters the environment.

Buried at Sea
Can trapping carbon dioxide in a sub-seafloor cavern help decrease greenhouse gases? Scientists from the Scripps Institution of Oceanography and Norway's Statoil are testing new methods of carbon dioxide sequestration that may help to reduce global warming.
