    Science objectives/activities planned:
Service and recover/deploy wellhead (and in one case seafloor) instrumentation at 7 “CORK” instrumented boreholes near Juan de Fuca Ridge. Of the 7 borehole sites, 4 are original CORK designs visited many times with Alvin in past, and 3 (1026B, 1301A, 1301B) are new designs installed in summer of 2004 and revisited once with ROPOS. Three sites (857D, 1024C, and 1025C) are isolated and will require one devoted dive each. The other four sites (1026B, 1027C, 1301A, 1301B) are closely spaced and the remaining dives will probably each visit more than one of these four sites. Possible night-time work for Cowen one or two nights at Endeavour Axis.
