This was confirmed by finding some unreasonable values particularly during deep casts. An estimate of water depth was made by adding the maximum depth sampled and the bottom altimetry reading. In cases where the water depth entry differed from the estimate by more than 4m and where the altimetry profile shows those values are reliable, the estimate was used to replace the water depth entry. This was done for 16 casts including most casts deeper than 400m that sampled within 15m of the bottom. The entries for other deep casts are suspect but altimetry is not available or not reliable enough to make a better estimate. Events for which the entry was adjusted are: #37, 40, 45, 46, 48, 50, 75, 89, 91, 92, 105, 106, 148, 154, 171 and 180. Conductivity, Transmissivity, Fluorescence:URU:Seapoint and PAR data are nominal and unedited except that some records were removed in editing temperature and salinity. There were serious problems with Niskin bottles and lanyards with reports in the logs of tops not being seated properly and leaks in spigots. Chips were noted on one Niskin and it broke during a later cast. The comparison of CTD dissolved oxygen and salinity with bottle samples was clearly affected by these problems, so recalibration was based on the results of cruise 2018-26 that followed 2018-39 and used the same equipment. These problems also made it impossible to make an estimate of accuracy for the dissolved oxygen sensor mounted on the CTD. For more details on the problems with bottles see the chief scientist's post-cruise report "PAC2018-039_Science Cruise Report view.pdf" in the DOC folder. NOTE: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. For details on the CTD data processing see document: 2018-039_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
