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 10 -99 () (0.25E-02 1) Salinity:T1:C1 PSS-78 10 -99 () (-0.5E-02 1) $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 9 5.1 14.9406 20.8 4.320 8 32.0027 121 31.9755 0 6.999 0 0.0 0 10.4 0 0.30 0 8 11.0 14.4261 25.7 2.684 7 32.0528 121 32.0686 0 6.451 0 1.4 0 14.1 0 0.50 0 7 21.1 9.8112 52.7 1.396 6 32.4613 121 32.4576 0 5.883 0 10.2 0 14.0 0 1.18 0 6 30.7 8.9324 56.5 0.875 5 32.5335 121 32.5322 0 6.245 0 9.9 0 10.9 0 1.09 0 5 51.2 8.1420 57.1 0.694 4 32.8315 121 32.8306 0 4.488 0 21.1 0 25.9 0 1.75 0 4 75.5 7.5364 56.0 0.221 3 33.3705 121 33.3729 0 3.185 0 29.2 0 40.1 0 2.27 0 3 101.5 7.0398 52.4 0.696 2 33.7133 121 33.7103 0 1.684 0 35.3 0 54.6 0 2.67 0 2 112.8 7.0029 48.3 0.424 1 33.7420 121 33.7435 0 1.778 0 35.7 0 57.2 0 2.74 0
