Estimating Exchange Rates of Water in Embayments using Simple Budget Equations.
Keith Sverdrup, University of Wisconsin-Milwaukee
Simple budgets may be used to estimate the exchange of water in embayments that capitalize on the concept of steady state and conservation principals. This is especially true for bays that experience a significant exchange of freshwater. This exchange of freshwater may reduce the average salt concentration in the bay compared to seawater if it involves addition of freshwater from rivers, R, and/or precipitation, P. Alternatively, it may increase the average salt concentration in the bay compared to seawater if there is relatively little river input and high evaporation, E. Since freshwater input changes the salt concentration in the bay, and salt is a conservative material, it is possible to combine two steady state budgets for a bay, one for salt and one for water, to solve for the magnitude of the water flows that enter and exit the bay mouth. Students will make actual calculations for the inflow and outflow of water to Puget Sound, Washington and the Mediterranean Sea and compare them to actual measured values.
Exploring the Link between Hurricanes and Climate using GCM Results
Cindy Shellito, University of Northern Colorado
This activity requires students to examine global climate model output available online and consider the potential impact of global warming on tropical cyclone initiation and evolution. As a follow-up, students ...
Is There a Trend in Hurricane Number or Intensity?
Todd Ellis, SUNY College at Oneonta
This lab guides students through an examination of the hurricane record to determine if there is a trend in hurricane intensity over the past 40 years and introduces some issues related to statistics and ...
Sea Ice Extension for the Earth as a System Learning Activity
Gary Randolph, GLOBE

Using Google Earth to measure seacliff erosion rates
Alfred Hochstaedter, Monterey Peninsula College
This lab uses Google Earth to measure the rate of seacliff retreat. It touches upon coastal processes, natural hazards, and coastal management issues. The central focus of the lab is in the Monterey Bay area.

Steve LaDochy, California State University, Los Angeles
This online set of activities help students learn properties of ocean waves, wind-wave relationships and properties of tsunamis.
Lisa Doner, Plymouth State University
This is a homework assignment that focuses student attention on ongoing hurricane/tropical storm development, often during the height of hurricane season. The students are directed to a web site (I like ...
Melinda Huff, Northeastern Oklahoma Agricultural and Mech Coll
This is a simple homework assignment that will reinforce topics discussed in lecture as well as enabling students to search and analyze information on the web.
Climate Change and Atlantic Hurricanes: A GIS Inquiry
Chris Van de Ven, Albion College
Students make hypotheses about how hurricane numbers, locations, or intensities have been changing, and then use hurricane tracks, wind speed, barometric pressure, and dates to test their hypotheses.
