Design, Implementation, and Assessment of an Undergraduate Interdisciplinary Watershed Research Laboratory

This article discusses the establishment of Shippensburg University's Burd Run Interdisciplinary Watershed Research Laboratory and the advantages of linking disciplinary perspectives across courses in geology, geography, biology, and teacher education. The laboratory provides an easily adaptable conceptual model for improving environmental science education at teaching-oriented institutions nationwide. Its success is largely attributable to three factors: the project is student-centered and goal specific; the selected watershed is accessible, diverse, and at a manageable scale; and the Laboratory Advisory Board provides for continuous revision, adaptation, and improvement.

Comparing Rain-Gauge Data with Radar-Derived Precipitation Estimates

In this lab, student teams collect rain-gauge data and compare it with radar-derived (NEXRAD) precipitation estimates. They use GIS to look for discrepancies between the two datasets and explain them by looking for sources of error in the method. This website details the lab's context and learning goals, and includes teaching notes and materials, assessment recommendations, and links to useful references and resources.

Geographically Isolated Wetlands Are Important Biogeochemical Reactors on the Landscape

Wetlands provide many ecosystem services, including sediment and carbon retention, nutrient transformation, and water quality improvement. Although all wetlands are biogeochemical hotspots, geographically isolated wetlands (GIWs) receive fewer legal protections compared with other types of wetlands because of their apparent isolation from jurisdictional waters. Here, we consider controls on biogeochemical functions that influence water quality, and estimate changes in ecosystem service delivery that would occur if these landscape features were lost following recent US Supreme Court decisions (i.e., Rapanos, SWANCC). We conclude that, despite their lack of persistent surfacewater connectivity or adjacency to jurisdictional waters, GIWs are integral to biogeochemical processing on the landscape and therefore maintaining the integrity of US waters. Given the likelihood that any GIW contributes to downstream water quality, we suggest that the burden of proof could be shifted to assuming that all GIWs are critical for protecting aquatic systems until proven otherwise
