Waterbot Data Update

We are just getting preliminary data from the Waterbots we installed in the park last week, but we are already seeing some interesting trends in the data. The above chart is a graph of Conductivity (red line) and Temperature (blue line) over the last week. Conductivity is represented as microsiemens per centimeter (the amount and rate of electricity that can pass through the water), and temperature is represented as 10 times the actual degrees Celsius (to make it graph on the same range as conductivity).

The conductivity fluctuates daily, with temperature, and you can see that on the evenings of the 21st, 22nd, and 23rd, conductivity reached the same low level. Interestingly on the 24th the conductivity dipped slightly less than the previous days. This could be the result of rain on the 24th (a little over a tenth of an inch) that may have washed various inorganic salts into the creek. Keep tuned in to the blog where we will periodically post the data we are collecting in and around the Park.

Partnerships with Pittsburgh Parks Conservancy and Carnegie Mellon University Expands MGT:21 Program

Taiji Nelson and Jake Francis in Frick Park, Pittsburgh along Nine Mile Run

Jake Francis, director of education at the Schrader Environmental Education Center, and Taiji Nelson, education program coordinator for Pittsburgh Parks Conservancy, are exploring sites within Pittsburgh’s Nine Mile Run Watershed for the installation of a WaterBot that will be used in the expansion and update to Mission Ground Truth:21.

The WaterBot is just one new instrument that MGT:21 scientists and students will be using to measure the health of western Pennsylvania and West Virginia watersheds. Developed by Carnegie Mellon University’s CREATE Lab, the WaterBot is a relatively inexpensive, yet accurate, in-stream water-sensing bot that measures temperature and conductivity at frequent intervals and uploads that information wirelessly to allow students to examine longitudinal data and compare their one-time stream samples with a much larger set of statistics.

Francis and Nelson are also researching sites for Pittsburgh students to conduct research in Frick Park as part of MGT:21. The dynamic partnership between Oglebay Institute, the Pittsburgh Parks Conservancy, and Carnegie Mellon University will bring the Mission Ground Truth:21 program to thousands of new students, expand to new public lands (including parks and schools), and link these students together using the latest technology and scientific tools.

MGT:21 was developed in 2000 by a team of regional educators and scientists and funded by the Claude Worthington Benedum Foundation and Richard King Mellon Foundation to actively engage middle school students in the scientific process. The curriculum consists of an integrated, interdisciplinary and inquiry-based 7th or 8th grade ecosystem assessment program that uses the “living laboratory” and state-of-the-art technologies to determine the ecological health of deciduous forest and freshwater stream ecosystems, as well as the decision-making process to weigh trade-offs between ecosystem values and functions. Annually, over 2,000 students from Ohio, West Virginia, and Pennsylvania conduct research at Oglebay Park and calculate the health of its streams and forests.
