Surface Trends for Medicine Lake

The RUSS data from Medicine Lakehas been summarized to show the average values of the measured parameters in the lake's surface layer on each day.

NOTE: Currently the RUSS unit is limited to an uppermost sampling depth of about 0.7 meters. Typically, we will average values for 1, 2, and 3 meters to calculate the mean "surface water" value.

      1. temperature
      2. turbidity
      3. dissolved oxygen
      4. pH
      5. % oxygen saturation
      6. electrical conductivity

Also available is a downloadable Excel spreadsheet (it's about 80 Kbytes) that contains all of the data and charts listed above.

These data should be considered "provisional" until otherwise indicated. The data are undergoing several rounds of QA/QC review and some of the data may be modified at a subsequent date. We chose to leave the data hose on full blast whenever possible to familiarize ourselves with the operation and maintenance requirements of the RUSS units and to generate real data for use in developing curricula and lesson plans. Data gaps were associated with various RUSS system upgrades and occasional gremlins.
