6/4/12 - 6/21/12
Pre-cruise preparation at C-MORE

-LISST 1285: problems with pressure sensor.
Run water into pressure cavity to dissolve salt. The pressure decreased slowly from ~200 m to ~4 m (6/21/12).
-ACS malfunctioned in the last cruises.
Tested in the lab and stopped logging reporting an error "connection timed out", after 33, 77 and 31 minutes in three separate tests. A later test showed what according to the Wetlabs technician is a block in the internal wheel.
Instrument sent to the manufacturer.
-LISST 1421: sent by OSU to replace 1285 till the pressure sensor is again reliable.

Pre cruise preparation at HOTSPOT

-Mounted 2 LISST sensor in the cage (the second in the space left by the ACS)
-Adjusted position of LICOR sensor to have a better vertical orientation
