LCMM diver after completing a dive (LCMM Collection). Additional Safety and Dive Protocols Extensive dive briefings were held each day before operations commenced which included a discussion of safety aspects, potential hazards, and emergency procedures. A detailed dive log was kept of each day’s activities which recorded dive and weather conditions, time (diver in and out), air pressure (diver in and out), and tasks completed. While divers were submerged, an international dive flag (Alpha flag) and a civilian “diver-down” flag (red with diagonal white stripe) were flown from the boat platform, alerting boat traffic to the presence of divers in the water. 43
FINAL Phase IB Underwater Archaeological Resources Report for Onondaga Lake Superfund Site Decontamination Procedure The dive operations required contact with lake water, and some contact with bottom sediment. The following decontamination protocol was performed after each dive (Figure 32). Decontamination assistants wore eye protection and latex gloves: 1. The diver with his gear in place was assisted onto the bow of the R/V Lophius. 2. The diver and his gear were rinsed with lake water to remove any bulk sediments. 3. The diver and his gear were sprayed with a solution of Alconox and water; if excess sediments were observed, that area was scrubbed with a brush. 4. The diver and his gear were thoroughly rinsed with clean water. All wash water was allowed to run into the lake via the boat’s bow door. Figure 32.

UNDERWATER ARCHAEOLOGICAL TECHNIQUES The methods and procedures used during the dive verification fieldwork at the Onondaga Lake Superfund Site were standards in the fields of nautical archaeology. The methods used during the project are discussed in a number of archaeological manuals. 114 Common references to specific archaeological techniques, for example those concerning archaeological illustration, were used to develop standards for the project. 115 Dive verification was accomplished using two primary methods: visual survey and metal detection. To visually survey an area, the diver employed a survey technique that best addressed the type of anomaly 44
