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.

Teleconnections part of Project EDDIE:Teaching Materials:Modules
Kaitlin Farrell, University of Georgia; Cayelan Carey, Virginia Polytechnic Institute and State Univ
Ecosystems can be influenced by teleconnections, in which meteorological, societal, and/or ecological phenomenon link remote regions via cause and effect relationships. Because it is difficult to predict how ...

Measuring Ground Motion with GPS: How GPS Works part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

Converging Tectonic Plates Demonstration part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Bomb Cyclones - They're Explosive! part of Project EDDIE:Teaching Materials:Modules
Jacqui Degan, Cape Fear Community College
Storms can have devastating impacts on coastal communities. Typically, tropical storms like hurricanes get the most attention, but there are other types of storms that occur at more northern latitudes that can be ...

Nutrient Monitoring in the Chesapeake Bay part of Project EDDIE:Teaching Materials:Modules
Akinyele Oni, Morgan State University; Niangoran Koissi, Morgan State University
The Chesapeake Bay waters receive input from rivers and streams from areas of Washington D.C, Maryland, Delaware, Virginia, West Virginia, and some parts of New York and Pennsylvania. Historically, humongous ...

Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards part of Project EDDIE:Teaching Materials:Modules
Christopher Berg, Orange Coast College; Beth Pratt-Sitaula, EarthScope; Julie Elliott, Michigan State University
Students work with high precision GPS data to explore how motion near a plate boundary is distributed over a larger region than the boundary line on the map. This allows them to investigate how earthquake hazard ...

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 ...

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 ...

Climate Change Effects on Lake Temperatures part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State Univ; Kaitlin Farrell, University of Georgia
Climate change is modifying the thermal structure of lakes around the globe. Because it is difficult to predict how lakes will respond to the many different aspects of climate change (e.g., altered temperature, ...
