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.

Lake Mixing Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Carey, C.C., J.L. Klug, and R.L. Fuller. 1 August 2015. Project EDDIE: Dynamics of Lake Mixing. Project EDDIE Module 3, Version 1. cemast.illinoisstate.edu/data-for-students/modules/lake-mixing.shtml. Module development was supported by NSF DEB 1245707.
Stratified lakes exhibit vertical gradients in organisms, nutrients, and oxygen, which have important implications for ecosystem structure and functioning. Mixing disrupts these gradients by redistributing these ...

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 ...

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 ...

Unit 6.1 - Biogeochemical Modeling Framework part of Critical Zone Science
Adam Wymore, University of New Hampshire-Main Campus
In this unit, students will learn about the dynamic movement of nutrients among and within ecosystems primarily through the reading and discussion of scientific literature. This unit is generally subdivided into ...

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 5.1 - Water Balance of a Tree part of Critical Zone Science
Martha Conklin, University of California-Merced
The assignment is to calculate an annual water balance for a tree using data gathered at the Southern Sierra Critical Zone Observatory. In the framework of experimental design, students will organize around a ...

Unit 2.2 - Basic Critical Zone Concepts part of Critical Zone Science
Ashlee Dere, University of Nebraska at Omaha; Susan Gill, Stroud Water Research Center
Students will learn about geoscience-specific methods used to analyze data in the Critical Zone from data-driven activities and short presentations by their peers. The topics include the use of carbon isotopes, ...

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 ...

Macro-Scale Feedbacks part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State Univ; Kaitlin Farrell, University of Georgia
Environmental phenomena are often driven by multiple factors that interact across space and over time. In freshwater lakes and reservoirs worldwide, carbon cycling and subsequent carbon dioxide (CO2) and methane ...
