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). Chlorophyll samples were analyzed at IOS in Room 2423 within ~2 weeks of the cruise. 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. Precision Statement: Chlorophyll values ranged from 0.01-1.69 ug/l. Average %CV for this cruise was 3.72% with 7 out of 104 duplicate pairs having a CV>10% and 1 out of 104 duplicate pairs having a CV>30%. Our average dataset %CV is 2.83 % for 2013 - 2015 so the overall quality of this dataset is within 1 standard deviation of this average and is very good. For details see worksheet “CV%” in file QF2017-01CHL*.xls. Oxygen samples were analyzed at sea and on shore using an automated Winkler titration system (Metrohm Dosimat model 876 and a UV light source and detector with a 365nm filter controlled by LV02_876 software designed and constructed by Scripps Institution of Oceanography) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details including a duplicate analysis, see document QF2017-01OXY*.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 on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 7 - 25 days after collection. For details including a duplicate analysis, see document QF2017-01SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples was collected and frozen immediately. Another set of samples from 400m and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. 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. For details including a duplicate analysis, see document QF2017-01nuts*.xls. DMS samples were collected in 250mL ground glass stoppered bottles and stored in a fridge, in the dark and removed one at a time before analysis. A sample was loaded onto the stripper and purged with UHP Nitrogen for 10 minutes at ~100mL/min. The DMS was extracted from the water and absorbed on to a Tenax TA trap kept at -80C. The trap was subsequently desorbed at 100 deg C (with a dewar containing boiling water) onto a Choromasorb 330 column which eluted onto a Flame Photometric Detector (FPD). All samples were run as soon as possible after being collected. For more detail see file "2017-01 DMS report.doc" and for data and duplicate analysis see "DMS summary (2017-01).xls." The minimum detectable level for DMS is 0.10 nmol/L, so “0” values should be interpreted as <0.1nmol/L. Cesium Analysis: Large volume (~60 L) water samples were collected and then passed through potassium cobalt ferrocyanide (KCFC) resin columns to selectively extract Cs isotopes from seawater. Column extraction efficiencies are generally greater than 96% as determined using spiked yield tracers with resin columns arranged in series. The isotopes 137Cs and 134Cs were subsequently measured on the oven-dried KCFC resins in the laboratory using high purity Ge well detectors. All data were decay-corrected to the time of sampling. A second level of analysis was often undertaken by subsequently decay correcting the data to April 6 2011 which was the time of maximum discharges from Fukushima. Detection limits (DL) for 137Cs and 134Cs were generally 0.10 Bq/m3 and 0.13 Bq/m3 respectively so "0" values should be interpreted as < detection limit. Detector efficiencies were measured using National Institute of Standards and Technology (NIST) and National Bureau of Sciences (NBS) calibration standards (e.g., NBS 4350B river sediment) and IAEA reference materials All the CTD variables are averaged over the same pressures in order to have one line of data per sample. The lowest sample number was used to represent a sample. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

The Transmissivity channel was removed because of frequent shifts in values during casts and large variations between values during repeat casts. The data are available, by request, from the chief scientist. 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. It is recommended that users check extracted chlorophyll values where available. Dissolved oxygen was calibrated using the method described in SeaBird Application Note #64-2, June 2012 revision, except that a small offset in the fit was allowed.
