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. ------------------------------------------------------------------- Pressure 2002.4 - replicates between alkalinity samples was large but analysis looked fine. *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---- 10---11-- 12 ---13-- 1 !Samp Pressu Temperat Trans Fluores Bo Salinity Numb Salinity F Alkalin Fl Carbon: F !le_ re ure: missi cence: tt :T0:C0 er_o :Bottle l ity: ag Dissolv l !Numb Primary vity URU: ~u ~bin ~ Total ~T ed: ~ !er Seapoin mb _rec l ot Inorgan i ! t er ords e al ic c !---- ------ -------- ----- ------- -- -------- ---- -------- - ------- -- ------- - *END OF HEADER 229 6.1 14.3450 4.6 1.568 24 32.3137 121 32.3160 -99.00 -99.00 207 2001.2 1.9553 52.8 0.148 2 34.5776 62 34.5782 2421.60 2384.03 f 206 2002.0 1.9552 52.8 0.149 1 34.5775 70 34.5791 2421.22 f 2382.88 f 224 2002.3 1.9542 52.8 0.153 19 34.5777 60 34.5779 -99.00 -99.00 212 2002.3 1.9545 52.8 0.150 7 34.5776 64 34.5794 -99.00 -99.00 211 2002.3 1.9546 52.8 0.150 6 34.5776 60 34.5794 -99.00 -99.00 210 2002.3 1.9548 52.8 0.149 5 34.5776 57 34.5770 2419.91 f 2385.53 f 209 2002.3 1.9550 52.8 0.149 4 34.5775 60 34.5775 2419.78 f 2385.33 f 208 2002.4 1.9547 52.8 0.149 3 34.5776 66 34.5781 2419.78 cf 2383.48 215 2002.5 1.9545 52.8 0.150 10 34.5777 120 34.5776 -99.00 -99.00 213 2002.5 1.9544 52.8 0.148 8 34.5777 65 34.5766 -99.00 -99.00 214 2002.8 1.9542 52.8 0.149 9 34.5778 119 34.5760 -99.00 -99.00 227 2002.9 1.9544 52.8 0.152 22 34.5777 65 34.5763 -99.00 -99.00 221 2002.9 1.9540 52.8 0.150 16 34.5779 68 34.5805 -99.00 -99.00 225 2003.1 1.9542 52.8 0.153 20 34.5779 61 34.5799 -99.00 -99.00 217 2003.1 1.9544 52.8 0.149 12 34.5777 77 34.5790 -99.00 -99.00 219 2003.2 1.9540 52.8 0.152 14 34.5778 69 34.5782 -99.00 -99.00 218 2003.2 1.9542 52.8 0.150 13 34.5777 70 34.5782 -99.00 -99.00 216 2003.2 1.9545 52.8 0.152 11 34.5776 92 34.5782 -99.00 -99.00 228 2003.5 1.9542 52.8 0.152 23 34.5778 120 34.5779 -99.00 -99.00 220 2003.5 1.9541 52.8 0.150 15 34.5778 69 34.5792 -99.00 -99.00 222 2003.8 1.9538 52.8 0.151 17 34.5779 60 34.5797 -99.00 -99.00 226 2003.9 1.9543 52.8 0.152 21 34.5777 63 34.5780 -99.00 -99.00 223 2003.9 1.9542 52.8 0.151 18 34.5777 62 34.5765 -99.00 -99.00
