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 183 4.4 13.6542 14.6 1.344 20 32.4448 121 32.4466 0 6.164 0 11.1 0 20.6 0 1.11 0 182 10.2 13.6549 12.3 1.333 19 32.4455 121 -99.0000 0 6.156 0 11.2 0 20.5 0 1.11 0 181 21.7 13.6521 10.7 1.330 18 32.4456 121 -99.0000 0 6.255 0 11.1 0 20.5 0 1.11 0 180 30.6 12.0429 11.5 1.456 17 32.5345 121 -99.0000 0 6.403 0 11.6 0 21.4 0 1.15 0 179 49.8 6.1258 40.9 1.342 16 32.7383 121 -99.0000 0 7.088 0 17.1 0 27.5 0 1.53 0 178 76.4 4.9599 49.7 0.484 15 32.9615 121 -99.0000 0 6.226 0 22.9 0 35.4 0 1.81 0 177 104.1 4.1568 51.9 0.204 14 33.4808 121 -99.0000 0 4.382 0 30.8 0 52.6 0 2.25 0 176 125.7 4.0800 51.8 0.180 13 33.6514 121 -99.0000 0 2.961 0 36.4 0 66.1 0 2.60 0 175 150.2 4.0608 52.0 0.171 12 33.7484 121 -99.0000 0 2.268 0 38.9 0 72.7 0 2.76 0 174 201.4 4.0016 52.3 0.158 11 33.8408 121 -99.0000 0 1.494 0 42.0 0 82.9 0 2.94 0 173 249.8 3.9241 52.2 0.156 10 33.9065 121 -99.0000 0 1.111 0 43.5 0 90.4 0 3.05 0 172 301.0 3.8710 52.3 0.158 9 33.9692 121 -99.0000 0 0.935 0 44.1 0 96.4 0 3.10 0 171 402.1 3.7834 52.4 0.155 8 34.0814 121 -99.0000 0 0.713 0 44.4 0 107.7 0 3.09 0 170 601.4 3.4728 52.6 0.154 7 34.2299 121 -99.0000 0 0.506 0 45.4 0 125.5 0 3.09 0 169 799.7 3.1417 52.7 0.156 6 34.3197 121 -99.0000 0 0.450 0 45.3 0 137.8 0 3.12 0 167 1001.0 2.8024 52.7 0.156 4 34.3946 54 -99.0000 0 0.393 0 45.5 0 149.8 0 3.14 0 168 1001.0 2.8028 52.7 0.156 5 34.3945 120 -99.0000 0 0.380 0 45.6 0 150.0 0 3.15 0 166 1249.6 2.4920 52.8 0.156 3 34.4620 121 34.4636 0 0.458 0 45.7 0 159.3 0 3.13 0 165 1501.0 2.2546 52.9 0.154 2 34.5136 121 34.5156 0 0.677 0 45.5 0 166.0 0 3.08 0 164 2001.7 1.9148 53.1 0.149 1 34.5853 121 34.5864 0 1.409 0 43.6 0 172.8 0 2.93 0
