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 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-- - !Samp Pressu Temperat Trans Fluores Bo Salinity Numb Salinity F Oxygen: F Nitra F Silic F Phosph F !le_ re ure: missi cence: tt :T0:C0 er_o :Bottle l Dissolv l te_ l ate l ate l !Numb Primary vity URU: ~u ~bin ~ ed ~ plus_ ~ ~ ~ !er Seapoin mb _rec l e Nitri t t t ! t er ords e d te e e e !---- ------ -------- ----- ------- -- -------- ---- -------- - ------- - ----- - ----- - ------ - *END OF HEADER 299 5.1 16.3636 14.3 0.506 20 31.9068 121 31.9042 0 5.859 0 0.0 0 4.6 0 0.39 0 298 10.7 16.2076 10.9 0.532 19 31.9038 121 -99.0000 0 5.882 0 0.0 0 4.5 0 0.39 0 297 20.8 16.1638 11.0 0.600 18 31.9027 121 -99.0000 0 5.968 0 0.0 0 4.6 0 0.40 0 296 30.9 11.5116 21.1 3.610 17 32.1130 121 -99.0000 0 7.113 0 1.3 0 7.1 0 0.55 0 295 50.3 8.9438 48.1 0.951 16 32.2382 121 -99.0000 0 6.362 0 9.6 0 11.4 0 1.08 0 294 76.0 7.9049 52.9 0.330 15 32.4660 121 -99.0000 0 6.175 0 12.5 0 13.6 0 1.24 0 293 100.6 7.3957 53.7 0.172 14 32.8059 121 -99.0000 0 5.260 0 18.4 0 21.9 0 1.61 0 292 125.3 7.1299 53.5 0.147 13 33.1890 121 -99.0000 0 4.451 0 23.0 0 29.5 0 1.86 0 291 150.0 6.7955 53.3 0.144 12 33.4568 121 -99.0000 0 4.009 0 25.9 0 34.8 0 2.02 0 290 200.2 6.1012 53.6 0.145 11 33.7633 121 -99.0000 0 3.333 0 30.5 0 46.2 0 2.26 0 289 249.6 5.7803 53.7 0.149 10 33.8707 121 -99.0000 0 2.564 0 34.7 0 57.1 0 2.50 0 288 302.0 5.3480 53.8 0.149 9 33.9152 121 -99.0000 0 1.933 0 37.8 0 66.2 0 2.73 0 287 400.1 4.8207 54.0 0.151 8 33.9858 121 -99.0000 0 1.275 0 41.2 0 79.4 0 2.96 0 286 600.4 4.1572 54.2 0.152 7 34.1488 121 -99.0000 0 0.525 0 44.4 0 104.5 0 3.19 0 285 801.1 3.6451 54.3 0.155 6 34.2720 121 -99.0000 0 0.298 0 45.2 0 123.5 0 3.27 0 284 1000.8 3.2284 54.3 0.155 5 34.3603 121 -99.0000 0 0.288 0 45.8 0 138.7 0 3.29 0 283 1249.8 2.6837 54.5 0.153 4 34.4348 120 34.4324 0 0.408 0 45.6 0 154.7 0 3.25 0 282 1250.2 2.6830 54.5 0.154 3 34.4350 95 34.4326 0 0.409 0 45.9 0 155.0 0 3.24 0 281 1501.5 2.3775 54.6 0.153 2 34.4937 121 34.4902 0 0.604 0 45.1 0 163.6 0 3.19 0 280 2000.7 1.9194 54.7 0.150 1 34.5841 121 34.5816 0 1.410 0 43.2 0 173.3 0 3.04 0
