DRBC Tests Top-Bottom Dissolved Oxygen Logger

On June 27, 2014 DRBC staff deployed a test metering system to measure dissolved oxygen (DO) in the tidal Delaware River near Burlington, N.J. This particular set-up is made of two data loggers (i.e. meters), one that will take near bottom DO readings and one that will take near surface DO readings.

The purpose of this test deployment is to determine if the set-up works, is able to withstand tidal river conditions, and also to determine if there are differences in DO levels dependent on where DO is being measured (top vs. bottom). DRBC staff will be checking on this deployment periodically to retrieve data from the data card and to also complete any needed maintenance.
