Cast #111 was full of pressure spikes, so was not prepared for archiving. There was no calibration sampling during this cruise. During 4 previous cruises that used CTD#0456, conductivity and salinity data were bad and were removed from all files. The dissolved oxygen sensor performed normally during 2023-020 and 2023-021 but performed erratically during 2023-003 and 2023-022 with some profiles looking normal and others having spikes and/or unbelievable values. The erratic performance continued through this cruise, with some profiles that looked normal while others had negative values, large spikes or small spiky sections. Some of the spikes were amenable to editing, but channel Oxygen:Dissolved:SBE was removed from casts #32, 37, 43, 47, 52, 83, 120, 127, 136, 141, 145, 157.
