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. ------------------------------------------------------------------- Comments from secondary file: Q:\Cruise_Data\2004-20\CTD\che\2004-20-0050.nuts ------------------------------------------------ Sample #264 - NO3 poor peak shape *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 276 5.2 16.3598 11.0 0.543 22 31.9705 121 31.9683 0 5.813 0 0.1 0 4.8 0 0.39 0 275 11.0 16.3540 10.6 0.613 21 31.9713 121 31.9684 0 5.818 0 0.0 0 4.8 0 0.39 0 274 20.9 16.3474 10.7 0.673 20 31.9712 121 31.9851 0 5.857 0 0.1 0 4.8 0 0.40 0 273 31.4 11.6549 23.2 1.397 19 32.2634 121 32.2570 0 7.082 0 3.3 0 7.6 0 0.68 0 272 41.1 9.7880 30.4 1.676 18 32.3309 121 32.3381 0 6.956 0 7.3 0 9.9 0 0.94 0 271 51.1 8.2483 49.5 0.701 17 32.3822 121 32.3822 0 6.655 4 10.0 0 11.5 0 1.09 0 270 61.5 7.6573 51.1 0.439 16 32.4510 121 32.4517 0 6.456 4 11.9 0 12.6 0 1.19 0 269 74.9 7.0172 52.3 0.271 15 32.4930 121 32.4911 0 6.334 4 13.7 0 15.8 0 1.31 0 268 101.1 6.5567 52.9 0.187 14 32.7548 121 32.7598 0 5.749 4 18.2 0 22.5 0 1.55 0 267 126.9 6.3924 52.8 0.154 13 33.1926 121 33.2048 0 4.687 0 23.8 0 31.3 0 1.84 0 266 150.7 6.1234 52.3 0.148 12 33.5047 121 33.5041 0 4.159 0 27.0 0 37.5 0 2.02 0 265 201.1 5.5569 52.8 0.150 11 33.7540 121 33.7503 0 3.441 0 30.6 0 49.1 0 2.21 0 264 252.4 5.2949 52.9 0.151 10 33.8479 121 33.8482 0 2.409 4 35.8 0 62.1 0 2.54 0 263 301.8 5.1364 52.9 0.150 9 33.9076 121 33.9071 0 1.753 4 38.3 0 68.7 0 2.72 0 262 401.1 4.4161 53.5 0.153 8 33.9759 121 33.9748 0 1.147 4 42.0 0 84.4 0 2.97 0 260 600.3 3.9840 53.6 0.154 6 34.1555 89 34.1559 0 0.470 0 43.9 0 108.0 0 3.17 0 261 600.6 3.9842 53.6 0.154 7 34.1556 120 34.1531 0 0.463 4 43.9 0 107.8 0 3.17 0 259 801.2 3.5789 53.7 0.155 5 34.2721 121 34.2704 0 0.300 0 44.6 0 124.3 0 3.23 0 258 1001.0 3.1558 53.8 0.156 4 34.3491 121 34.3505 0 0.281 0 45.1 0 137.7 0 3.24 0 257 1250.9 2.7403 53.9 0.154 3 34.4366 121 34.4353 0 0.355 0 44.9 0 153.0 0 3.23 0 256 1501.2 2.3892 54.0 0.153 2 34.4921 121 34.4911 0 0.595 0 44.7 0 162.5 0 3.18 0 255 2001.6 1.9401 54.1 0.149 1 34.5794 121 34.5779 0 1.367 0 42.9 0 173.7 0 3.04 0
