For details see document QF2017-03OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with disposable nylon inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab at IOS on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 7 to 12 days after collection. For details see document QF2017-03SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. All analysis was performed on frozen samples. All samples were returned to IOS for analysis. They were analyzed using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney.

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. There was no extracted chlorophyll sampling during this cruise. Dissolved oxygen was calibrated based on the results of cruise 2017-63 when the same equipment was used. WARNING: The transmissometer used for this cruise malfunctioned during two previous uses. There is no clear evidence of problems during this cruise but the data should be used with caution. There is a lot of variability in the transmissivity during repeat casts, but this was expected due to the nature of the sampling.
