The National Oceanic and Atmospheric Administration
(NOAA) Undersea Research Program featured on CNN.com: On July
20, 2005, NOAA's Aquarius was featured on CNN.com as a result of
a press conference on July 19 held at the National Press Club in
Washington, D.C.
Background: Aquarius is an underwater ocean laboratory
located in the Florida Keys National Marine Sanctuary. The laboratory
is deployed three and half miles offshore, at a depth of 60 feet,
next to spectacular coral reefs. Scientists live in Aquarius during
ten-day missions using saturation diving* to study and explore our
coastal ocean. Aquarius is owned by NOAA and is operated by the
NOAA Undersea Research Program Center at the University of North
Carolina at Wilmington.
* Scientific divers that use SCUBA diving to conduct
their research have limitations that can inhibit their productivity
underwater. Limiting factors such as, diving depth, gas mixtures
and supply, weather, and decompression obligations can have a significant
impact on the amount of time a scientist will actually have to conduct
their research underwater. By using a diving technique known as
"saturation diving," scientists can lengthen the time
they spend underwater. Once a diver is saturated at 60 foot depth,
he can spend unlimited time around that depth and decompress once
at end of his dive. The revolutionary development of undersea habitats
(also known as undersea laboratories) has made "saturation"
diving a reality for scientific divers. An undersea habitat is a
pressurized facility that provides a living space for a small team
of divers on the ocean floor and extends the depth ranges and time
at depth for the divers.
Significance: NOAA's Aquarius is the only underwater laboratory
in the world. The article published on cnn.com stresses the importance
of the Aquarius as a research tool. NOAA through its Undersea Research
Program provides scientists the ability to live and work beneath
the waves in the Aquarius undersea laboratory. The habitat accommodates
four scientists and two technicians for missions averaging ten days.
Aquarius successfully supported 80 missions between 1993 and Aquarius
scientists work to understand our changing ocean and the condition
of coral reefs. Coral reefs are threatened locally, regionally,
and globally by ncreasing amounts of pollution, over-harvesting
of fisheries, disease, and climate change. Science achievements
from Aquarius include discoveries related to the damaging effects
of ultraviolet light on coral reefs, geological studies that use
fossil reefs to better understand the significance of present-day
changes in coral reefs, research that is rewriting the book on how
corals feed, growth studies of important sponges that uncovered
surprising factors affecting their abundance and distribution, water
quality studies to evaluate sources of pollution, and long-term
studies of reefs to distinguish between changes caused by natural
system variability and humans.
