A look at over a decade of data from Physical Geography weekend field trips across Puget Sound by Everett Community College. Students learn as undergraduates how to measure water quality, map it, and build story maps using utilizing the scientific method (hypothesis). This data is publicly available as a service on ArcGIS online, as well as student story maps built from it.

Since 2008, data has been collected three times a year on saltwater and freshwater from 4 base locations: Orcas Island; Deception Pass; Port Hadlock; and Sequim. Over 40 saltwater and 16 freshwater locations are maintained from these bases, measuring a wide degree of ambients (and growing all the time). Freshwater data is sampled and tested using a Photometer, while Saltwater data is tested using a multi-probe YSI meter.

Much of the equipment we are now using was made possible by a grant from the Rose Foundation, and we are now upgrading the metadata of our data to become public and authoritative. This will be a first attempt to pull some of the data together and conduct some analysis, but this data is meant to be shared by everyone.

This poster would fit the theme of "Geographies of Access: Inclusion and Pathways"
