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.

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 10 -99 () (0.25E-02 1) Salinity:T1:C1 PSS-78 10 -99 () (-0.5E-02 1) $END !-1-- --2--- ---3---- --4-- ---5--- 6- ---7---- -8-- ---9---- 10---11-- 12--13- 14--15- 16--17-- 18---19-- 20---21-- 22--23-- 2 !Samp Pressu Temperat Trans Fluores Bo Salinity Numb Salinity F Oxygen: F Nitra F Silic F Phosph F Alkalin F Carbon: F Chloro F !le_ re ure: missi cence: tt :T0:C0 er_o :Bottle l Dissolv l te_ l ate l ate l ity: l Dissolv l phyll: l !Numb Primary vity URU: ~u ~bin ~ ed ~ plus_ ~ ~ ~ Total ~ ed: ~ Extrac ~ !er Seapoin mb _rec l e Nitri t t t a Inorgan i ted e ! t er ords e d te e e e l ic c d !---- ------ -------- ----- ------- -- -------- ---- -------- - ------- - ----- - ----- - ------ - ------- - ------- - ------ - *END OF HEADER 30 5.0 17.4141 25.8 0.587 20 31.8256 121 31.8475 5.868 0.0 6.2 0.38 2155.08 1929.54 0.38 29 11.0 16.8078 26.4 0.969 19 31.9684 121 31.9691 5.997 0.2 8.0 0.45 2162.93 1937.63 0.59 28 20.7 16.4666 26.9 0.720 18 32.2633 121 32.2962 6.080 0.0 2.0 0.41 2174.21 1955.06 0.37 27 30.3 13.3365 32.9 2.029 17 32.4215 121 32.4289 6.526 0.9 4.2 0.55 2182.72 1969.67 0.38 26 50.6 9.6731 51.7 0.521 16 32.4942 121 32.4950 6.530 5.9 8.2 0.86 2163.45 2008.55 0.27 25 76.6 8.2641 59.6 0.257 15 32.6811 121 32.6586 6.068 11.9 12.0 1.13 2205.65 2037.75 0.10 24 103.6 7.7319 59.6 0.244 14 33.0693 121 33.0447 5.048 18.9 20.1 1.49 2217.37 2091.14 -99.00 23 125.0 7.3214 59.7 0.168 13 33.4934 121 33.4874 4.647 24.3 28.3 1.76 2249.60 2140.16 -99.00 22 150.0 7.0101 59.7 0.156 12 33.6640 121 33.6673 3.862 26.7 34.9 1.91 2259.62 2164.80 -99.00 21 175.1 7.0451 59.7 0.160 11 33.8056 121 33.8044 3.433 29.1 39.6 2.05 2270.71 2184.82 -99.00 20 201.0 6.9904 59.8 0.156 10 33.8973 121 33.8954 2.645 32.5 45.6 2.26 2279.52 2210.41 -99.00 19 253.0 6.6536 59.8 0.158 9 33.9584 121 33.9575 2.190 35.0 52.1 2.44 2284.30 2230.93 -99.00 18 308.1 6.2046 59.8 0.159 8 34.0060 121 34.0029 1.587 38.3 61.1 2.67 2293.03 2258.05 -99.00 17 400.8 5.5840 60.1 0.161 7 34.0512 121 34.0508 1.081 41.0 73.1 2.90 2310.20 2286.44 -99.00 16 599.3 4.6856 60.0 0.162 6 34.1762 121 34.1764 0.501 44.4 96.7 3.17 2336.83 2329.17 -99.00 15 798.8 4.1861 59.9 0.165 5 34.2740 121 34.2740 0.310 45.5 112.3 3.26 2365.77 2346.72 -99.00 14 1000.2 3.5603 59.7 0.165 4 34.3830 120 34.3830 0.574 45.9 131.7 3.32 2378.72 2367.81 -99.00 13 1000.2 3.5603 59.7 0.165 3 34.3829 97 34.3847 0.493 46.0 131.5 3.29 2381.74 2367.34 -99.00 12 1252.3 2.9419 60.2 0.161 2 34.4708 121 34.4709 0.802 45.9 149.7 3.25 2406.35 2380.37 -99.00 11 1299.6 2.8198 60.1 0.163 1 34.4863 121 34.4885 0.803 45.8 153.0 3.23 2418.48 2385.85 -99.00
