Analysis methods: ----------------- Chlorophyll samples were analyzed frozen at IOS in Room 1310. The average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. For details see worksheet “CV%” in file QF2012-50CHL*.xls. Salinity samples were collected in 200 mL type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry, Ltd. and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab at IOS on a Guildline 8400B salinometer standardized with IAPSO standard seawater about 4 months after collection. For details including a duplicate analysis, see document QF2012-50SAL*.xls. Nutrient samples were collected in plastic tubes. Samples were stored fozen and later analyszed using an Astoria analyzer at IOS. For details including a duplicate analysis, see document NUTS_QF2012-50nuts*.xls. References: 1.

CTD data were taken from the downcast at 10m due to much higher data quality during downcasts. The fluorescence data are nominal and unedited except that some records were removed in editing temperature and salinity. There was no Dissolved Oxygen sampling, so no estimate is made of accuracy. Recalibration was based on results of cruise 2012-01. It is likely that there has been some drift since then which usually results in values that are low by a few %. Salinity samples were stored for 4 months before they were analyzed. Based on recent cruises using the same types of bottle inserts, it appears that significant evaporation occurs after 2 months, and that by 4 months bottle values are likely to read high by an average of >0.01. Furthermore, all but one sample came from 10db where the salinity gradients were high, making the comparison even less suitable for recalibration of salinity. The last good calibration of the salinity from these sensors came from cruise 2012-01 in Feb. 2012 and showed the primary salinity to be very close to bottle values. A pH sensor was attached to the CTD for casts #355 to #409, but the data are not included in the files to be placed in the IOS Data Library because no field calibration information was available at the time of processing, and there are some concerns about how the sensors perform. For details on the processing see the report: 2012-50-proc.doc. ---------------------------------------------------------------------------------- !-1-- --2--- --3--- ---4---- ---5--- ---6---- ---7---- 8- --9--- --10- --11-- 12 --13-- 14 --15-- 16 --17-- 18 --19-- !Samp Depth: Pressu Temperat Fluores Salinity Salinity Fl Oxygen Oxyge Nitrat Fl Silica Fl Phosph Fl Chloro Fl Phaeo- !le_ Nomina re ure: cence: :T0:C0 :Bottle ag : n: e_ ag te ag ate ag phyll: ag Pigmen !Numb l Primary URU: ~o Dissol Disso plus_ ~t ~i ~p Extrac ~a t: !er Wetlabs tt ved: lved: Nitrit ri ca ha ted ct Extrac ! le SBE SBE e te te te ed ted !---- ------ ------ -------- ------- -------- -------- -- ------ ----- ------ -- ------ -- ------ -- ------ -- ------ *END OF HEADER 388 10.0 11.0 9.8400 2.710 30.5120 30.4990 3 5.78 252.1 18.3 6 32.7 6 1.58 6 2.87 6 1.18
