Nutrient Loading Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Castendyk, D.N., T. Meixner, and C.A. Gibson. 6 June 2015. Project EDDIE: Nutrient Loading. Project EDDIE Module 7, Version 1. Module development was supported by NSF DEB 1245707.
Estimating nutrient loads is a critical concept for students studying water quality in a variety of environmental settings. Many STEM/Environmental science students will be asked to assess the impacts of a proposed anthropogenic activities on human water resources and/or ecosystems as part of their future careers. This module engages students in exploring factors contributing to the actual loads of nitrogen that are transmitted down streams. Nitrogen is a key water quality contaminant contributing to surface water quality issues in fresh, salt, and estuarine environments. Students will utilize real-time nitrate data from the US Geological Survey to calculate nitrate loads for several locations and investigate the interplay of concentration and discharge that contributes to calculated loads.

Assessing the Risk of Invasive Species Using Community Science Data part of Project EDDIE:Teaching Materials:Modules
Matthew Heard, Belmont University

Paleoclimate and Ocean Biogeochemistry part of Project EDDIE:Teaching Materials:Modules
Allison Jacobel, Middlebury College
This module guides students through an examination of how surface ocean productivity relates to global climate on glacial-interglacial timescales and how the availability of ocean nutrients can be correlated with ...

Wind and Ocean Ecosystems part of Project EDDIE:Teaching Materials:Modules
Alanna Lecher, Lynn University; April Watson, Lynn University
Wind has a fundamental impact on ocean ecosystems. Wind drives physical processes, including current development and upwelling through Ekman transport. These physical processes, in turn, have cascading impacts on ...

Unit 4.2 - Carbon Budgets part of Critical Zone Science
Jim Washburne, The University of Arizona
The purpose of this unit is to explore, compare, contrast, and interpret carbon fluxes from the Ameriflux network to better appreciate the critical factors that account for the different timing and magnitudes of ...

Unit 6.2 - Biogeochemical Examples part of Critical Zone Science
Adam Hoffman, University of Dubuque
In this week-long unit students will explore Critical Zone function and dynamics as they relate to nutrient cycling in agricultural systems and nutrient pollution into aquatic systems. This unit is generally ...

Modeling Rare Plant Distributions Using ArcGIS part of Teaching Activities
Elizabeth Crook, University of California-Irvine
In this activity, students work with rare plant occurrence data from the Nature Reserve of Orange County, California to create species distribution maps in ArcGIS. Students are given shapefiles of species ...

Climate Drivers of Phenology part of Project EDDIE:Teaching Materials:Modules
Emily Mohl, Saint Olaf College
Many species' life cycles are strongly influenced by temperature, but other cues, like day length and precipitation, can also trigger life cycle changes. Phenology is a way of recording the time when events, ...

Lake Metabolism Module part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State Univ
Different lakes exhibit a range of catchment sizes, morphometry, and land use that contribute to differences in lake function. These functional differences mean that lakes vary in ecosystem services such as habitat ...
