Examples of mid-water oxygen minima in areas of hypoxic bottom waters, July
2004. Oxygen, solid line; fluorescence, dashed line; density, dotted line. Station A4 is 37 km
northwest of Southwest Pass of the Mississippi River, 20-m depth, 0035 GMT, sunrise; station
C6C is 100 km west of Southwest Pass and 100 km east of the Atchafalaya River, 18-m depth,
1610 GMT, mid-morning; station D
4 is 120 km from Southwest Pass and 110 km from the
Atchafalaya River, 30-m depth, 0555 GMT, midnight. Data are from a SeaBird system with
SBE43 oxygen probe calibrated by Winkler titrations, derived density, and fluorescence from a
Turner SCUFA. Data from: N.N. Rabalais, LUMCON.
