Demobilization 495 4 45-day period; billeting and messing support, generators, fuel supply; and carpentry support, intra-a toll communications; minor welding emergency medical support, and evacuation provisions in a contingency 1980 to 26 situation. The survey was scheduled for the period 12 January to February 1980. A mobile trailer was moved from Enewetak Island Enjebi to provide billeting and showerfacilities for the 15 participants who would camp there. Onetrailer was already permanently installed at Enjebi to support the tree nursery. Portable, tactical radios were assigned to the team to provide communications support from the base survey vessel, the LCM-8, to the whalers and to the base camp on Enjebi, as well as to provide 24-hour communications from Enjebi to the Enewetak Island base camp radio control station. Emergency MEDEVACsupport was provided by the helicopters attached to the JTG and H&N provided personnel for messing support and to operate the boats. Food resupply runs were established to insure a supply of fresh food wasavailable at Enjebi. Prior to the arrival of the technical survey crew, a 48-hour test of the communications system was performed and constant communications were maintained throughout the period. On 11 January 1980, a C-141 MACspecial mission flight took off from Ellington AFB, Texas, for Honolulu with the survey equipment, contractor personnel, and Field Command representatives. On 13 January, the flight departed Honolulu for Enewetak. Onarrival, all of the personnelparticipating in the project were briefed by JTGrepresentatives on the environment, safety considerations, communications systems, area of operations, MEDEVAC provisions, weather and tides, occupational and health hazards, and recreational activities. After equipment preparations, the survey team joined with the H&N personnel and moved to the northern camp at Enjebi on 17 January 1980. By 4 February, EASI survey operations were complete at the Mike and Koa Craters and, based on operational experience, Field Command authorized the conduct of overwater multipak and refraction surveys at the Oak Crater.53 Despite some periods of high winds and heavy wave action during which operations were suspended, the measurementsat Oak Crater were completed on 21 February 1980, 3 days aheadof the planned completion date. The navigation stations and towers which had been emplaced to support the various surveys were demobilized and, on 22 February, the base camp at Enjebi was vacated. All contractor-supplied equipment was packed and crated and, on 26 February, the EASI participants departed Enewetak by C-141 for Honolulu and subsequent return to Houston, Texas. Even though cleanup demobilization efforts accelerated greatly during the January-February time frame and, in fact, all military personnel were scheduled to depart by 28 February 1980, the EASI project was supported
