Poleward Heat Transport Jigsaw
E. Christa Farmer, Hofstra University
Based on great plate tectonic exercise by Sawyer et al. (2005 JGE), this small-group exercise with maps of data about earth's energy balance helps students visualize poleward heat transport.
Jennifer Bown, Clackamas Community College
Students choose shell fragments from different species of Molluscs and calculate percent lose after soaking in different ph solutions for different periods of time. They research ocean acidification and especially ...
Detecting El Niño in Sea Surface Temperature Data
David Smith, GLOBE; Betsy Youngman

Is There a Trend in Hurricane Number or Intensity?
Todd Ellis, Western Michigan University
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 ...
Estimating Exchange Rates of Water in Embayments using Simple Budget Equations.
Keith Sverdrup, National Science Foundation
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.
Learning About Marine Sediments Using Real Data
Kristen St. John, James Madison University
This exercise set explores marine sediments using real core photos and composition data from the scientific ocean drilling programs DSDP, ODP, and IODP in an inquiry-based approach.
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.
Seasonal variation in light, mixing depth and primary productivity in temperate northern hemisphere waters
Lauren Sahl, Maine Maritime Academy
In this exercise students work with light, temperature, and phytoplankton biomass proxy (chlorophyll a concentration) data to; Become more skilled in reading and interpreting semi log graphs, temperature profiles, ...
Grocery Store Survey of Aquaculture Products
Susan Richardson, Florida Atlantic University
Students work in pairs to survey seafood items sold in local grocery stores or fish markets, recording whether items are farm-raised or wild caught, fresh, frozen or preserved, as well as country of origin. ...
Melting ice cubes
Mirjam Glessmer, Leibniz Institute for Science and Mathematics Education at Kiel University, Germany
Explore how melting of ice cubes floating in water is influenced by the salinity of the water. Important oceanographic concepts like density and density driven currents are visualized and can be discussed on the ...
