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 were measured using an Autoanalyzer II, following the procedures outlined in Barwell-Clarke and Whitney (1997). Nitrate/silicate samples were defrosted about 24 h before analysis. Phosphate samples were rapidly defrosted in moving room temperature air or warm water. Lab temperature was noted periodically, and may be found on the original data sheets; it was generally around 26C. !-1-- --2--- ---3--- --4-- --5-- --6--- !Bott Pressu Oxygen: Nitra Silic Phosph !le_ re Dissolv te_ ate ate !Numb ed plus_ !er Nitri ! te !---- ------ ------- ----- ----- ------ *END OF HEADER 272 1.2 5.970 0.0 4.7 0.31 271 9.8 5.965 0.0 4.7 0.30 270 19.7 5.960 0.0 4.7 0.35 268 30.0 5.971 4.6 6.8 0.78 268 49.3 6.244 -99.0 -99.0 -99.00 267 73.7 6.020 8.8 11.6 1.03 266 99.2 4.263 20.7 24.6 1.31 265 123.6 3.685 25.1 31.0 1.89 264 148.6 3.679 27.2 35.9 1.92 263 173.6 3.519 28.0 39.7 2.12 262 199.1 3.287 29.7 43.1 1.94 261 249.0 2.857 32.9 52.9 2.25 260 300.5 2.592 32.4 56.2 2.28 259 400.4 1.532 39.4 75.8 2.40 258 500.1 0.962 42.1 88.9 2.61 257 599.4 0.629 37.6 90.8 2.91 256 799.1 0.290 44.3 113.6 3.25 255 999.6 0.271 44.7 130.0 3.32 254 1200.0 0.359 42.8 140.1 3.12 253 1499.6 0.762 42.1 156.9 3.09 252 2002.4 1.474 41.3 174.0 2.83
