Following is a brief chronology of the first week of setup
Monday, July 26:
Unpacked two boxes that Steve sent on Friday, containing the data system,
the console computer, and the sonic cables. Hooked up everything at WHOI
and everything ran okay. Steve worked with Janet Fredericks and Gordon to
change IP addresses to the WHOI internal network.
Tuesday, July 27:
Steve and Janet took ASTER to the MVCO (Martha's Vineyard Coastal Observatory)
shore lab, while Peter Sullivan and I went out to ASIT (Air-Sea Interaction
Tower) to install the data system and the spare CSAT. This was accomplished
successfully and Steve could see the data on ASTER.
Wednesday, July 28:
The sonic booms and yokes arrived and we mounted the yokes, CSAT electronics
and cables on the crossbeams. WHOI replicated our steel towers in
aluminum, but the dimensions of the sides are slightly too small so that the
yokes do not fit snugly. The two grooves on the hinged part of the yoke
do not match the tubing on the new tower section.
Thursday, July 29:
Arrived at WHOI early to take the crossbeams out to ASIT, but the wave
heights were too high. Postponed until Friday.
Friday, July 30:
Left WHOI at 6:30 am for ASIT. Raised the lower crossbeam onto the ASIT
platform at 12 m. Mounted the sonics on the crossbeam and lowered into
place on the two vertical tower sections mounted by WHOI on the ASIT
'diving board'. The nine sonics (a1-a9) are in place but at an angle of
approximately 45 degrees above horizontal. The sonics increase in
position number (a1-a9) and in serial number from right to left when
viewed from behind.
Tuesday, August 3
Raised the upper crossbeam onto the ASIT platform, mounted sonics, and mounted
the crossbeam onto the vertical support tower sections. Lots of adjustment of
the yokes to retighten them and bring the sonics into nominal alignment with
each other. Jim mounted the inertial motion package on the upper crossbeam
and we lowered the whole shebang. In the process, Jim also mounted his sonic,
Licor 7500 and TRH at the 9 m level on the left-hand (facing outward) vertical
support tower.
