CHAPTER IV, SECTION 4 Figure 4-28. Pier and Leading Ramp at Site Tare CHANNELS and BEACHING CONDITIONS. Channels leading to the various sites on Eniwetok Atoll were well established during the period of the previous two test operations. Although considerable shifting of beach sand was observed, no significant sanding up of channels occurred. The work undertaken for this operation consisted of lifting, overhauling and replanting of channel buoys at Ursula, and con- struction of a concrete ramp and the establishment of temporary channel lighting for night Dewar operations at this site. For channels and beaching conditions at this Atoll see Figure 4-30. At the commencement of operations in Bikini Lagoon, a reconnaissance of all sites was made and the best natural approaches to the sites were located. The only natural satisfactory landing beach was found at How. Atsites Tare, George, Charlie, Nan, Able and Uncle, blasting of coral heads and reefs was undertaken. Channels were marked with buoys con- structed of empty oil or gas drums and anchor- ed with concrete blocks. Range lights were erected at Tare, Charlie and George. A pier was constructed at Tare, and moles at Charlie and Able. For channels and beaching conditions at this Atoll see Figure 4-31. The pier and loading ramp at Tare is shown in Figure 4-28. The installation and maintenance of nav- igational aids for sea-going vessels was the re- sponsibility of the U.S. Coast Guard. Thelargevessel channels within Bikini Lagoon were wire dragged by the U.S. Navy with support provided by the H&N boat pool The U.S. Navy Hydrographic office charts No. 6032 and 6033 revised as of 1 January 1954 indicate the hydro- graphic conditions and navigational aids in both lagoons. MOORING BUOYS. At Eniwetok Atoll a number of existing small craft mooring buoys were lifted, overhauled and replaced off Elmer and Fred. A number of additional buoys were planted under Job IV work orders for small Page 4-37
