Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner 10AU fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). 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 QF2012-03nut-chl*.xls. Salinity samples were collected in 200 mL type ll glass bottles with disposable plastic 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 days after the end of the cruise. For details including a duplicate analysis, see document QF2012-03SAL*.xls. Nutrient samples were collected in plastic tubes. All samples were later analyzed at IOS using the Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document NUTS_QF2012-03nut-chl*.xls. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

CTD data were taken from the upcast at 10m. Fluorescence data are nominal and unedited, except that some records were removed in editing temperature and salinity. There was no calibration sampling for dissolved oxygen, but the results of cruise 2012-04 were used to derive DO concentration. Recalibration of CTD salinity was based on many 10m bottles and 1 deep bottle from this cruise and from sampling during 2012-04. Both comparisons were limited by great variability, but salinity data are likely good to +/-0.003. The SBE pH sensor malfunctioned throughout the cruise. For details on the processing see processing report: 2012-03-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: :T1:C1 :Bottle ag : n: e_ ag te ag ate ag phyll: ag Pigmen !Numb l Secondar URU: ~o Dissol Disso plus_ ~t ~i ~p Extrac ~a t: !er y Wetlabs tt ved: lved: Nitrit ri ca ha ted ct Extrac ! le SBE SBE e te te te ed ted !---- ------ ------ -------- ------- -------- -------- -- ------ ----- ------ -- ------ -- ------ -- ------ -- ------ *END OF HEADER 115 10.0 10.0 7.5844 0.542 29.7670 29.7957 0 5.93 258.7 15.4 0 26.3 0 1.37 0 0.25 6 0.17
