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 8.5m due to much higher data quality during downcasts. The comparison of SBE25 salinity with bottle samples suggests that the CTD was reading low. However, 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 samples came from about 8db where the salinity gradients were high, making the comparison even less suitable for recalibration of salinity. This was the first use of this CTD since the temeprature and conductivity sensors were last recalibrated, so it is expected that their calibrations would not have drifted significantly. No recalibration was applied to CTD salinity. The pressure sensor appeared to read high by 0.22db, which is within the accuracy quoted for the sensor. Pressure was recalibrated by adding 0.22db to avoid negative values. A pH sensor was attached to the CTD, 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 processing report: 2012-50-proc.doc. ---------------------------------------------------------------------------------- !-1-- --2--- --3--- ---4---- ---5---- ---6---- 7- --8--- 9- --10-- 11 --12-- 13 --14-- 15 --16-- !Samp Depth: Pressu Temperat Salinity Salinity Fl Nitrat Fl Silica Fl Phosph Fl Chloro Fl Phaeo- !le_ Nomina re ure: :T0:C0 :Bottle ag e_ ag te ag ate ag phyll: ag Pigmen !Numb l Primary ~o plus_ ~t ~i ~p Extrac ~a t: !er tt Nitrit ri ca ha ted ct Extrac ! le e te te te ed ted !---- ------ ------ -------- -------- -------- -- ------ -- ------ -- ------ -- ------ -- ------ *END OF HEADER 166 10.0 8.5 11.1300 30.5210 30.5990 3 2.0 0 9.4 0 0.50 0 2.21 6 1.09
