NAAMES04 IFCB READ ME

During NAAMES04 the IFCB had several problems that required major changes in the instrument.  When using data from this leg bear in mind that the camera and computer have been changed during the cruise and as a result sensitivity of the instrument has changed. 

Other comments

1. Change of camera: 20180322 starting with file D20180322T215446_FCB107- new camera
Alignment throughout the cruise was not ideal. We did several Micro-90 treatments (sample2cone, let sit for a few minutes and then flush fast with both pumps) to remove debris that may have stuck to the walls of the flow cells but it did not improve by much. After changing the camera. New (old) camera did not seem to fit well as it was pushed all the way to the end with no room to move it further tin the direction needed to improve vertical alignment. 

2. Filters were not replaced since names 1. They may have cracked at some point as we noticed lots of particles/cells when running FSW and DIW samples. 
Filters replaced on 20180325. File D20180325T135914_FCB107 start with new filters

3. 20180328 some run crashed in the middle, network problem with the computer + a series of corrupted files (see log for flagged samples). Computer finally died on 20180401.
Rough seas- waited a day before could open it to replace; computer stack replaced on April 1. First file with new computer D20180402T125812_FCB107. Note- sensitivity have change (for the same gain/PTM).

4. Stations were short. To maximize inline time in station  (+incubation samples) we did not run as many micro layer samples on this leg. 

5. After installing new computer stack the time was 40 minutes early, look at the log for more details
