Lower than CTD by 0.004psu. Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter is controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples are analyzed fresh on board using a Technicon AAII auto- analyzer following methods described in Barwell-Clarke and Whitney (1996). Chlorophyll samples are collected in duplicate in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters are placed in glass scintillation vials and immediately frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract is decanted and measured using a Turner Designs 10-AU-005-CE fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll. Dissolved inorganic carbon (DIC) was determined using coulometric analysis. Total alkalinity (Alk) was determined by potentiometric titration. Complete documentation on DIC and ALK sampling, analysis and precision estimates can be found in the Carbon Excel file from the cruise located in the cruise "DOC" directory. . References: 1.

There remains some doubt about the CTD salinity which may be low by up to 0.004psu. ------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !--------------------- --------------- ---- ------ ------------ Temperature:Primary 'deg C (ITS90)' 10 -99 () (0.1E-02 1) Salinity:T0:C0 PSS-78 11 -99 (Pressure) (-0.8E-03 0.8E-06) Salinity:T1:C1 PSS-78 11 -99 (Pressure) (-0.137E-01 0.6E-06) $END !-1-- --2--- ---3---- --4-- ---5--- 6- ---7---- -8-- ---9---- - ---11-- - --13- - --15- - --17-- - --19-- - ---21-- 22 ---23-- 24 !Samp Pressu Temperat Trans Fluores Bo Salinity Numb Salinity F Oxygen: F Nitra F Silic F Phosph F Chloro F Carbon: Fl Alkalin Fl !le_ re ure: missi cence: tt :T0:C0 er_o :Bottle l Dissolv l te_ l ate l ate l phyll: l Dissolv ag ity: ag !Numb Primary vity URU: ~u ~bin ~ ed ~ plus_ ~ ~ ~ Extrac ~ ed: ~g Total ~T !er Seapoin mb _rec l e Nitri t t t ted e Inorgan an ot ! t er ords e d te e e e d ic ic al !---- ------ -------- ----- ------- -- -------- ---- -------- - ------- - ----- - ----- - ------ - ------ - ------- -- ------- -- *END OF HEADER 106 5.0 16.7007 14.2 0.294 23 32.2764 121 32.2752 0 5.972 0 3.2 0 9.0 0 0.60 0 0.14 0 1952.20 0 2186.10 3 105 10.1 16.5797 12.7 0.528 22 32.2787 121 32.2809 0 5.995 0 3.1 0 9.0 0 0.59 0 0.19 0 1950.60 0 2189.70 3 104 20.2 14.7775 16.0 0.617 21 32.3399 121 32.3437 0 6.623 0 3.7 0 9.0 0 0.60 0 0.20 0 1964.10 0 2197.90 3 103 31.5 10.3332 27.9 1.390 20 32.4129 121 32.4106 0 7.425 0 6.7 0 11.7 0 0.77 0 0.46 0 1987.40 0 2193.20 3 102 50.0 7.8516 47.5 1.713 19 32.4368 121 32.4393 0 7.241 0 10.0 0 13.0 0 1.06 0 0.46 0 2012.70 0 2196.90 3 101 75.9 7.0838 52.4 0.639 18 32.4927 121 32.4988 0 6.900 0 13.2 0 16.7 0 1.23 0 0.21 0 2034.10 0 2194.40 3 100 99.8 6.2802 56.0 0.338 17 33.2191 121 33.1550 0 5.853 0 20.0 0 24.6 0 1.56 0 -99.00 0 2096.80 0 2234.20 3 99 126.3 6.1467 56.3 0.176 16 33.6125 121 33.6128 0 5.029 0 23.3 0 31.4 0 1.64 0 -99.00 0 2138.30 0 2255.80 3 98 151.5 5.9192 56.3 0.161 15 33.7068 121 33.7133 0 4.880 0 24.1 0 37.1 0 1.73 0 -99.00 0 2152.30 0 2261.60 3 97 200.0 5.4779 56.3 0.153 14 33.7620 121 33.7633 0 3.990 0 28.8 0 47.3 0 2.00 0 -99.00 0 2184.20 0 2284.20 3 95 252.0 5.1400 56.5 0.155 12 33.8169 73 33.8185 0 2.973 0 33.7 0 60.2 0 2.35 0 -99.00 0 2229.90 6 2283.50 36 96 252.6 5.1399 56.6 0.155 13 33.8169 120 33.8181 0 2.988 0 33.6 0 59.4 0 2.32 0 -99.00 0 2228.40 0 2286.40 3 94 302.8 4.7497 56.8 0.164 11 33.8610 121 33.8613 0 2.285 0 37.2 0 69.4 0 2.55 0 -99.00 0 2259.50 0 2292.10 3 93 400.7 4.2776 57.3 0.155 10 33.9416 121 33.9410 0 1.508 0 41.5 0 84.4 0 2.85 0 -99.00 0 2286.60 0 2325.20 3 92 602.5 3.9037 57.6 0.156 9 34.1632 121 34.1606 0 0.641 0 44.2 0 110.8 0 3.11 0 -99.00 0 2334.80 0 2349.50 3 91 801.0 3.4358 57.7 0.165 8 34.2671 121 34.2680 0 0.356 0 45.5 0 128.2 0 3.15 0 -99.00 0 2362.50 0 2368.20 3 90 1001.0 3.0882 57.9 0.156 7 34.3531 121 34.3507 0 0.267 0 45.8 0 141.3 0 3.21 0 -99.00 0 2379.90 0 2379.30 3 89 1251.5 2.7359 58.0 0.156 6 34.4363 121 34.4361 0 0.332 0 46.2 0 154.4 0 3.19 0 -99.00 0 2387.80 0 2406.30 3 88 1503.9 2.3861 58.1 0.155 5 34.4983 121 34.4959 0 0.536 0 45.5 0 163.6 0 3.14 0 -99.00 0 2389.50 0 2417.50 3 87 2003.6 1.9249 58.2 0.151 4 34.5887 121 34.5858 0 1.366 0 43.5 0 173.9 0 2.97 0 -99.00 0 2377.00 0 2424.10 3 86 2503.5 1.7238 58.4 0.147 3 34.6292 121 34.6285 0 1.952 0 41.6 0 176.1 0 2.86 0 -99.00 0 2367.00 0 2434.10 3 85 3000.9 1.6039 58.3 0.147 2 34.6524 121 34.6500 0 2.443 0 40.4 0 175.1 0 2.77 0 -99.00 0 2354.60 0 2431.60 3 84 3601.4 1.5791 57.9 0.149 1 34.6650 121 34.6589 3 2.850 0 39.6 0 176.2 0 2.64 0 -99.00 0 2349.90 0 2444.60 3
