History of the Gulf of Mexico "Dead" Zone
Martin Farley, University of North Carolina at Pembroke
Student analysis of the last 1000 years of the Gulf of Mexico hypoxia zone (informally "dead" zone) by using relative abundance of low-oxygen tolerant benthic foraminifera. In this example of ...

Unit 6.2 - Biogeochemical Examples
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 ...

Anoxic Events - Instructor's Guide | Data Explorations
This exercise is a case study that, if used in full, takes students through the entire learning cycle from invitation to reflection as applied to a dead zone on the Oregon continental shelf. Pieces of the exercise ...

Nutrient Loading Module
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 Metabolism Module
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 ...

Module 4: Food and Water
Gigi Richard, Fort Lewis College
In this module, students will be introduced to the connections between water and agriculture. The first part of the module (4.1) explores how water is essential for growing food and how water is embedded in all of ...
