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 148 2.0 6.635 10.4 25.8 1.13 147 10.3 5.812 12.2 27.4 1.35 146 19.4 5.465 15.3 32.5 1.25 145 29.5 5.163 15.2 30.4 1.11 144 48.8 4.801 18.2 35.6 0.93 143 73.9 4.415 16.4 28.7 1.24 142 90.3 4.142 17.2 28.7 1.42
