In an effort to QC the dissolved oxygen data from the DNR geoduck outplant, I checked out WA Ecology’s online tool, the Environmental Information Management (EIM) System.
Here’s the website layout. I opted to search under the Results field
After experimenting a bit with search options, I searched for “dissolved oxygen”:
Here is a shot of the results table. I then downloaded all results.
The downloaded results file was a .csv. I opened in Excel and generated 2 histograms: 1) All DO data points measured in mg/L; 2) All DO data points measured in mg/L AND measurements from marine/salt/brackish water.
Main take-away: All DO data ranged from 0-21 mg/L, therefore the data points in the DNR dataset >21 should not be included in my data analysis.
