Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC900 Colorimeter is controlled by Visual-Basic program to titrate the oxygen samples. !-1-- --2--- ---3--- !Cons Depth Oxygen: !ecut Dissolv !ive_ ed !no !---- ------ ------- *END OF HEADER 147. 0.0 7.755 146. 5.0 7.192 145. 10.0 5.859 144. 15.0 4.685 143. 20.0 2.575 142. 25.0 0.067 141. 30.0 0.285 140. 34.0 0.072 148. 34.0 0.049
