Exploring Seafloor Topography
Sandra Swenson
DATA: Digital Elevation Model Data. TOOL: GeoMapApp. SUMMARY: Explore a timeline about how we have learned about the oceans. Construct a profile across the Atlantic Ocean and create 3-D visualizations of the seafloor.

Measuring Ground Motion with GPS: How GPS Works
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
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.

Paleoclimate and Ocean Biogeochemistry
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 ...

Hypoxia in Coastal Marine Ecosystems
Annette Brickley; Kathy Browne, Rider University; Gabriela Smalley, Rider University
Aquatic ecosystems are home to a complex intersection of physical and biological factors and an intersection of natural and anthropogenic factors. In the Chesapeake Bay, low oxygen events have occurred periodically ...

Indiana River Meanders Mapping Exercise
Emily Zawacki, Arizona State University at the Tempe Campus
In Indiana, major rivers and their tributaries cross much of the state. These rivers can produce significant hazards related to flooding and erosion, which threaten nearby residents and infrastructure. Rivers are ...

Unit 1: Collecting GPS Data
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure vertical and horizontal bedrock motion caused by a variety of geologic processes, such as plate movement and the changing amount of water and ice on Earth's surface. In this unit, students ...

Measure surface reflectance and albedo with smartphone apps
Jessie Turner, Old Dominion University
Using smartphones, students can measure the reflectance and albedo of water and other earth surfaces in the field. This is a great activity to reinforce the central concepts used in remote sensing. The smartphone ...

Modeling Rare Plant Distributions Using ArcGIS
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 ...

Unit 3: Glaciers, GPS, and Sea Level Rise
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure bedrock elevation change in response to the changing mass of glaciers. In this module, students will learn how to read GPS data to interpret how the mass of glaciers in Alaska and Greenland is ...
