EXPERIMENTAL DESIGN AND METHODS:

Transects were conducted in a motorboat with a sample inlet device located beneath the hull that, when the boat was moving, would force water into an enclosed chamber and past the sampling probe. Dissolved oxygen, percent saturation, conductivity, temperature and pH were measured in the chamber with a Hydrolab H2O probe (see ANALYTICAL METHODS).  On dates when DIC and pCO2 were measured, samples were collected in the outlet line into glass bottles, and killed with HgCl2.  As we did not need to stop at each station to obtain a sample, transects were completed quickly and represent a close to instantaneous dissolved oxygen transect of the estuary.

NOTES AND COMMENTS:

 

VARIABLE DESCRIPTION:

STATION = Station name and/or number

DIST = distance (km) from the Parker River Dam

COND = conductivity (mS / cm)

TEMP = temperature (C)

DO = dissolved oxygen (mg / l)

% SAT = dissolved oxygen percent saturation

pH = pH
