These are a few graphs made from GLOBE Student Data
collected by schools collaborating in the Ozark Hydrothon.
This effort was undertaken to see if students could identify
any measurable effects of human activities upon the
White River and its tributaries.

Since the linked pages are of actual data reported to the GLOBE dataset, you may change any of the display options available in the menu driven fields found at the linked pages. If you feel really ambitious, you can access the GLOBE Data search function (within the visualizations menu field) and compare any other selected school's data to ours in a graphical form just by selecting (or adding) their school and data fields.

Since only six sites can be displayed on any single graph, other Ozark Hydrothon sites can be displayed by removing one of those that appears and adding another from the menu driven display. Data from other GLOBE schools may also be displayed if you are willing to search, select and manipulate any of the thousands of reporting schools world-wide. If you need some help in using the GLOBE Visualizations, contact their Help Desk or drop me an e-mail with your specifics. I may not drop everything, but I will get back to you with an answer.

To illustrate this last type of visualization, I have linked Big Creek (a tributary of the White River) from another schools' data set with the Ozark Hydro-thon data to show a higher than normal nitrate loading of a stream. Big Creek in Baxter County carries the effluent of the City of Mountain Home Wastewater Treatment Plant. Cotter Access WR, Buffalo City Accres WR, and Shipps Ferry Access are all upstream of Big Creek. Norfork Village Access WR is downstream and on the opposite river bank from the mouth of Big Creek. By careful review of the data illustrated, you can make some interesting discoveries about our White River's dynamics.

Additionally, an Air / Soil Temperature datalogger was installed at Norfork Village Hydrology Site on 5 May 2002. Another datalogger was installed at Jordan Marina on Lake Norfork on 1 Nov 2003. Air temperature, and soil temperature at depths of 5, 10, and 50 centimeters is recorded every 15 minutes. Both datasets can br compared to recordings made by a third gidentical datalogger at the school weather station. Downloads can be obtained at the data access link here. Unfortunately, this equipment was lost in the flood of 24-25 April 2004

As a classroom experiment, non-GLOBE sanctioned water testing for chlorides and phosphates has been conducted on several area streams for the purpose of classroom comparison of the results of urban sprawl upon the environment. While no one would categorize this area as subject to urbanization, there is a human impact upon water quality which can be more easily identified using these tests. Results can be found below.
