Sample Number 507: SAL:Bottle - replicate outliers. Cap loose on replicate sample bottle. One value looks ok in COMPARE, other looks bad. Used better one. Sample Number 517: Bottle Number 24 - top valve not sealed; OXY:Bottle - compares well with Oxygen:Dissolved:CTD nonetheless. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with plastic inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater within 2 months of collection. The duplicate analysis is in file 2011-027_SAL.pdf. Oxygen samples were analyzed on an automated Winkler titration system (Brinkmann Dosimat model 765 and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). All samples were analyzed at sea. For details of the duplicate analysis see file 2011-027_OXY.pdf. Nutrient samples were collected in plastic tubes. Most samples were analyzed fresh at sea. A few loop samples were analyzed frozen at IOS. An Astoria analyzer was used following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate analysis see file 2011-027_NUT.pdf. NOTE: July 2013: A correction has been applied to Nitrate_plus_Nitrite:Bottle and Phosphate:Bottle data from deep-water cruises analyzed at IOS between 2009 and 2012. For details see the report: Corrections_to_Nitrate_and_Phosphate_Data_2009-2012.pdf. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours and analyzed 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 et al 1965). Chlorophyll samples were analyzed on board ship in a controlled temperature lab. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). For details on duplicate samples see file 2011-027_CHL.pdf. Phaeopigment data are provided for information only and no quality flags are assigned to them. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2011-027_DMS_report.pdf and for duplicates see file 2011-027_DMS.pdf. The minimum detectable level for DMSP-D:Bottle is 0.1 nM, so “0” values should be interpreted as <0.1. The minimum detectable level for DMSP-T:Bottle in this file is 0.1 nM from 0 to 20 dbar, and 1 nM from 20 to 200 dbar, so “0” values should be interpreted as < those values. DMSP data are limited to 2 significant figures. For details on analysis see document 2011-027_DMS_report.pdf. HPLC samples were filtered onto 47mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~2 months after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a, Chlide-a and Me-chlide. References: 1.

For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. The calibration of the Oxygen:Dissolved:CTD channel was done using the method described in the SeaBird Application Note #64-2 (Sea-Bird_64-2_Feb2010.pdf).

Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- 2- 3- --4--- ---5---- ---6---- ---7---- --8-- --9--- --10- ---11-- ---12--- 13 ---14-- --15- 16 --17- 18 --19-- 20 --21- 22 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phosph Fl Silic Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv n:Dis ag te_pl ag ate: ag ate: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottl ~o !er mb en CTD CTD: d:CTD Wetlabs tt Bottle: ottle tt ite:B tt tt e tt ! er ce Volume :Mass le Volume :Mass le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ----- -- ------ -- ----- -- *END OF HEADER 517 24 24 5.1 12.9592 32.5160 24.5034 52.8 6.27 273.4 1.194 32.5223 6 6.276 273.5 2 11.5 0 1.15 0 16.0 0 516 23 23 10.9 12.9574 32.5158 24.5036 52.7 6.25 272.4 1.623 32.5176 0 6.264 273.0 0 11.6 0 1.16 0 16.0 0 515 22 22 24.9 12.9302 32.5158 24.5089 53.7 6.26 272.6 2.037 32.5219 0 6.256 272.6 0 11.7 0 1.17 0 15.9 0 514 21 21 49.3 6.3145 32.7499 25.7616 59.5 7.28 316.8 2.315 32.7650 0 7.290 317.3 0 17.0 0 1.55 0 27.0 0 513 20 20 76.1 4.6461 32.7938 25.9907 63.3 7.08 308.2 0.813 32.7940 0 7.077 308.0 6 19.9 0 1.70 0 30.3 0 512 19 19 101.1 4.3344 32.8112 26.0372 64.5 7.03 305.7 0.339 32.8195 0 7.038 306.3 0 20.9 0 1.75 0 32.5 0 511 18 18 125.2 4.4073 33.1376 26.2889 64.7 5.68 247.1 0.124 33.1313 0 5.762 250.7 0 25.1 0 1.99 0 40.9 0 510 17 17 149.5 4.3397 33.6796 26.7265 65.0 3.50 152.1 0.097 33.6762 0 3.537 153.8 0 33.9 6 2.49 6 61.0 6 509 16 16 174.9 4.1294 33.7375 26.7944 65.1 3.00 130.5 0.087 33.7395 0 3.030 131.8 0 36.4 0 2.64 0 68.0 0 508 15 15 201.2 4.0060 33.7725 26.8349 65.2 2.63 114.2 0.052 33.7724 0 2.662 115.8 0 38.0 0 2.75 0 73.0 0 507 14 14 249.1 3.9690 33.8469 26.8978 65.4 2.07 89.8 0.058 33.8538 3 2.104 91.5 0 40.0 0 2.86 0 80.8 0 506 13 13 301.5 3.9621 33.9162 26.9536 65.5 1.57 68.4 0.039 33.9164 0 1.581 68.7 6 41.9 0 2.97 0 87.8 0 505 12 12 400.4 3.9113 34.0324 27.0512 65.7 1.07 46.6 0.037 34.0322 0 1.111 48.3 0 43.2 0 3.10 0 100.0 0 504 11 11 600.5 3.6097 34.1973 27.2126 65.9 0.63 27.3 0.045 34.1992 0 0.653 28.4 0 44.3 0 3.19 0 119.3 0 503 10 10 800.3 3.2000 34.3066 27.3389 65.9 0.53 22.9 0.047 34.3068 0 0.572 24.9 0 45.0 0 3.24 0 135.4 0 502 9 9 999.8 2.8818 34.3789 27.4257 65.9 0.48 21.0 0.039 34.3784 6 0.495 21.5 0 45.1 0 3.26 0 146.7 0 501 8 8 1250.4 2.5776 34.4478 27.5074 66.0 0.45 19.6 0.030 34.4579 0 0.452 19.6 2 45.4 0 3.28 0 158.2 0 500 7 7 1499.3 2.3016 34.5070 27.5781 66.1 0.63 27.6 0.032 34.5102 0 0.617 26.8 0 45.2 6 3.24 6 165.7 6 499 6 6 1999.5 1.9235 34.5860 27.6717 66.1 1.34 58.2 0.030 34.5868 0 1.331 57.8 0 43.1 0 3.09 0 170.6 0 498 5 5 2500.3 1.7025 34.6298 27.7238 66.2 1.99 86.5 0.031 34.6294 0 1.998 86.8 6 41.4 0 2.96 0 172.1 0 497 4 4 3000.1 1.5678 34.6568 27.7555 66.2 2.55 110.8 0.020 34.6581 6 2.569 111.6 0 39.7 0 2.83 0 170.9 0 496 3 3 3500.0 1.5107 34.6720 27.7719 66.2 2.91 126.5 0.016 34.6806 0 2.976 129.3 0 38.4 0 2.74 0 169.2 0 495 2 2 3998.0 1.4995 34.6809 27.7799 66.3 3.14 136.6 0.007 34.6796 0 3.177 138.0 0 37.8 0 2.69 0 168.6 0 494 1 1 4316.0 1.5201 34.6841 27.7809 65.5 3.18 138.2 0.015 34.6853 0 3.198 138.9 0 37.8 0 2.69 0 172.9 0
