By Mass Communications Specialist 1st Class Michael D. Kennedy, Fleet Public Affairs Center Det. In preparation for Talisman Saber 2007 (TS07), Sailors and embarked Marines aboard USS Juneau (LPD 10) are learning environmental protection measures to safely preserve Australia’s Great Barrier Reef. The main operating area for the exercise -- which will bring together nearly 32,000 U.S.-Australian forces for training -- is in Shoalwater Bay Training Area. The 1,000 square mile area near the Barrier Reef has a high environmental value. The area is administered by the Australian Army to ensure sound environmental practices are observed.
