Halas has been working to protect coral systems in Florida since 1981. After observing coral damage caused by careless anchoring, he took it upon himself to develop an environmentally friendly anchor and mooring buoy system that prevents damage to coral reefs. Then he worked to implement this anchorage system worldwide. Reef mooring buoys eliminate the need to drop anchor on fragile coral reefs by providing boaters with a convenient means of securing their vessels. In July 1981, Halas initiated the first experimental embedment anchor mooring system at French Reef, Key Largo National Marine Sanctuary in the Florida Keys. Drawing on coral core sampling techniques, a hole was drilled into the ancient limestone substrate and a stainless steel eye pin was cemented into the bottom, creating a strong attachment point for a riser, buoy, and polypropylene line. Over the next few years, over 80 buoys were placed out in the Florida Keys National Marine Sanctuary. Later, nonprofit organizations established buoys following Halas' design off Key West, Marathon, and Islamorada. Now, there are nearly 400 buoys in the Florida Keys Sanctuary.
