Samples were extracted in 90% acetone for 24 hours and analyzed in the lab on a Turner 10AU fluorometer which is calibrated annually with commercially pure chlorophyll a (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen 1965). For full results, see file "Hi Seas Salmon 2010-18Final*.xls." NOTE: Phaeopigment data are provided for information only and no quality flags are assigned to them. Salinity samples were collected in glass bottles and analyzed on Guildline Autosal model 8400B, S/N 69086, at IOS. Salinometers are standardized with IAPSO standard seawater. Full results are in file 2010-18-salinity*.xls. Nutrient samples were collected in plastic tubes and stored frozen and later analysed at IOS using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). File "Hi Seas Salmon 2010-18Final*.xls." includes the raw data and an analysis of duplicates. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

CTD data were taken from the upcast from 11.5db. For a few casts no CTD data were available at the sampling level. The SBE Dissolved Oxygen data are nominal and unedited except that some records were removed in editing temperature and salinity. Post-cruise calibrations were used for all sensors on the CTD. No estimate can be made of the precision of the SBE Dissolved Oxygen channel since there was no DO sampling. The availability of a post-cruise calibration in late December 2010 should minimize errors due to calibration drift, but not those due to slow response time. For details on the processing see processing report: 2010-18-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 Trans Salinity Salinity Fl Oxygen Oxyge Nitrat Fl Silica Fl Phosph Fl Chloro Fl Phaeo- !le_ Nomina re ure: missi :T0:C0 :Bottle ag : n: e_ ag te ag ate ag phyll: ag Pigmen !Numb l Primary vity ~o Dissol Disso plus_ ~t ~i ~p Extrac ~a t: !er tt ved: lved: Nitrit ri ca ha ted ct Extrac ! le SBE SBE e te te te ed ted !---- ------ ------ -------- ----- -------- -------- -- ------ ----- ------ -- ------ -- ------ -- ------ -- ------ *END OF HEADER 342 10.0 11.5 9.0914 52.6 27.3995 24.8273 0 4.10 179.1 15.8 0 39.9 0 1.41 0 0.19 6 0.12
