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 357 4.6 13.9572 7.3 4.767 13 29.8779 121 29.9017 0 7.237 0 0.6 0 3.0 0 0.40 0 356 10.1 13.9342 16.1 1.952 12 30.6969 121 -99.0000 0 6.325 0 3.0 0 8.1 0 0.58 0 355 20.0 10.0834 48.8 0.453 11 31.9097 121 -99.0000 0 4.832 0 16.1 0 28.1 0 1.63 0 354 30.4 9.2684 51.2 0.291 10 32.2463 121 -99.0000 0 4.109 0 20.0 0 35.5 0 1.90 0 353 40.3 8.9567 51.7 0.255 9 32.3960 121 -99.0000 0 3.867 0 21.4 0 38.0 0 1.96 0 352 49.9 8.7920 51.2 0.226 8 32.4883 121 -99.0000 0 3.798 0 21.9 0 38.6 0 1.98 0 351 75.3 7.8003 52.5 0.172 7 32.7163 121 -99.0000 0 3.429 0 25.1 0 42.2 0 2.07 0 350 100.0 7.1011 53.3 0.146 6 33.1146 121 -99.0000 0 3.386 0 26.7 0 43.8 0 2.10 0 349 125.3 6.6564 52.8 0.148 5 33.4531 121 -99.0000 0 2.685 0 30.6 0 51.6 0 2.32 0 348 150.4 6.2760 49.8 0.149 4 33.8093 121 -99.0000 0 2.076 0 34.5 0 60.2 0 2.53 0 347 183.2 6.1164 39.0 0.152 3 33.8723 121 33.8745 0 1.772 0 35.3 0 66.7 0 2.65 0 346 194.4 6.1163 38.5 0.153 2 33.8732 121 33.8757 0 1.807 0 35.4 0 66.9 0 2.66 0 345 198.6 6.1150 38.5 0.152 1 33.8749 121 33.8775 3 1.850 0 35.4 0 66.9 0 2.65 0
