Aquarius, the world's only underwater laboratory, was today re-installed on the sea floor at a depth of 63 feet at Conch Reef in the Florida Keys National Marine Sanctuary. After a series of systems tests, certification and dive training, science missions in Aquarius will resume in late March or April, the National Oceanic and Atmospheric Administration announced today.

Aquarius makes it possible for aquanaut-scientists to live and work under water continuously during 10-day missions to study North America's largest living coral reef system.

With eight science missions planned for 1998, Aquarius is the centerpiece of NOAA's comprehensive environmental research program aimed at better understanding and preserving endangered coral reef ecosystems in U.S. waters.

Following its first deployment on Conch Reef from September 1993 to May 1996, the Aquarius system was completely renovated and upgraded by the National Undersea Research Center at the University of North Carolina at Wilmington, Harbor Branch Oceanographic Institution, Fort Pierce, Fla., the Harris Corporation, Melbourne, Fla., and NOAA. UNCW operates Aquarius. NOAA owns Aquarius and funds its operations.

During the Aquarius science missions beginning next year, teams of four scientists from various universities will spend up to nine hours a day diving to conduct environmental research to better understand factors that affect the condition of coral reefs in Florida in particular, and the health of the coastal oceans in general. Aquarius operations are planned at Conch Reef through 2001.

Aquarius was retrieved from the Florida Keys and moved to Harbor Branch in September 1996 to be refurbished and upgraded to improve efficiency, safety and scientific operations. Previously, operations were monitored 24 hours a day from a support barge moored above Aquarius. The new system, dubbed "Aquarius 2000," instead operates using a stand-alone support buoy that will use microwave telemetry to provide live data, audio and video links from Aquarius to shore and to the Internet.

Computer and electronic capabilities in Aquarius, plus the extensive bottom time for aquanaut-scientists working from Aquarius, make it possible to conduct research that could not be done from the surface. Links to the Internet will provide other scientists and the public with a virtual window to Aquarius and Conch Reef while aquanauts conduct their studies.
