Day Date Time Activity TODAY 8/2 - Load Ship, test equipment 1 8/5 0700 Depart Honolulu 2 8/6 0700 Arrive Loihi after 24 hr transit. Check surface waters for signs of eruptive activity - discolored watrer, pumice, etc. CTD cast to obtain up-to-date water velocities and initial evaluation of plume activity. Deploy and record sonobuoys on approach to summit to get an initial indication of acoustic activity. 2 8/6 1500 Begin transponder array (long baseline acoustic navigation) tests. Begin initial SeaBeam survey to look for gross changesin topography. Deploy transponders as necessary. Calibrate transponder array. 2 8/6 2200 Begin CTD rosette and tow-yo casts. 0600 Evaluate CTD, SeaBeam, and sonobuoy results. Decision on if and where to conduct 1st dive, with pre-cruise preference for Pele's vents . 3 8/7 0700 A) Begin PISCES Dive 1. PISCES places instruments, collects rock samples, surveys and documents activity. KOK continues SeaBeam coverage in immediate area. OR B) If safety, weather or the lack of a clear target preclude a dive, continue CTD and CTD tow-yo casts. 3 8/7 1600 End PISCES Dive 1. CTD rosette casts on grid and as modified by suspected plume location. Continued sonobuoy monitoring of activity. 4 8/8 0700 A) Begin PISCES Dive 2. PISCES samples vent and plume waters, collects rock samples, continues documentation. OR B) If safety, weather or the lack of a clear target preclude a dive, continue CTD and tow-yo casts. 4 8/8 1600 End PISCES Dive 2. CTD rosette casts on grid andas modified by suspected plume location. Continued sonobuoy monitoring of activity. 5 8/9 0700 A) Begin PISCES Dive 3. PISCES samples vent and plume waters, collects rock samples, continues documentation of eruptive activity. OR B) If safety, weather or the lack of a clear target preclude a dive, continue CTD and tow-yo casts. 5 8/9 1600 End PISCES Dive 3. Re-survey active areas with SeaBeam, fill in any holes in water sampling grid. 6 8/10 2100 Depart Loihi 6 8/10 2000 Return Honolulu after 23 hour transit
