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 381 4.9 10.8664 38.5 0.696 14 29.6022 121 27.9780 0 4.943 0 14.4 0 29.2 0 1.45 0 380 11.3 10.5296 46.1 0.703 13 30.7044 121 -99.0000 0 5.005 0 14.5 0 25.5 0 1.54 0 379 20.8 10.4248 46.8 0.629 12 31.2872 121 -99.0000 0 5.259 0 13.8 0 24.4 0 1.52 0 378 31.1 9.8096 48.5 0.490 11 31.4727 121 -99.0000 0 4.429 0 17.6 0 30.9 0 1.77 0 377 50.7 8.7838 51.3 0.249 10 31.9359 121 -99.0000 0 3.534 0 23.0 0 40.9 0 2.03 0 376 75.7 7.8078 51.4 0.194 9 32.4897 121 -99.0000 0 2.837 0 27.1 0 51.2 0 2.29 0 375 101.2 7.1524 49.5 0.178 8 33.0395 121 -99.0000 0 2.303 0 29.4 0 60.4 0 2.52 0 374 126.1 7.0689 49.3 0.180 7 33.1127 121 -99.0000 0 2.289 0 29.5 0 60.9 0 2.53 0 373 151.3 7.0022 50.1 0.166 6 33.1571 121 -99.0000 0 2.362 4 29.9 0 59.9 0 2.49 0 372 175.9 6.9713 49.5 0.158 5 33.1790 121 -99.0000 0 2.299 0 30.2 0 61.1 0 2.50 0 371 200.6 6.9510 49.3 0.161 4 33.1946 121 -99.0000 0 2.289 0 30.3 0 61.2 0 2.51 0 370 250.8 6.9198 50.1 0.157 3 33.2183 121 33.2187 0 2.306 4 30.6 0 61.0 0 2.50 0 369 301.3 6.9119 47.8 0.159 2 33.2282 121 33.2289 0 2.263 4 30.5 0 62.8 0 2.54 0 368 325.3 6.9139 47.3 0.160 1 33.2288 121 33.2290 0 2.275 4 30.5 0 63.0 0 2.57 0
