Detecting El Niño in Sea Surface Temperature Data
David Smith, GLOBE; Betsy Youngman
DATA: Sea Surface Temperature (SST). TOOL: My World GIS. SUMMARY: Examine 15 years of SST data from the Pacific Marine Environmental Laboratory. Create and analyze average SST maps to identify El Nino and La Nina events.
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 ...
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, 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.
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.
Gulf Stream Heat Budget and Europe
Warren Tomkiewicz, Plymouth State University
Student groups are presented a problem scenario to research and make recommendations, predictions, and a resolution of the problem based on data and visualizations.
2004 Asian Earthquake and Tsunami Disaster Project
Char Bezanson, Eastview High School, Apple Valley, Minnesota
Students are employees of a unit of the United Nations responsible for coordinating disaster relief after a major disaster (the 2004 Asian Earthquake and Tsunami) occurs. The agency needs to understand the ...
Case Study: Coastal Stabilization Structures
Al Trujillo, Palomar College
This ocean activity is used to help students analyze different solutions to a real-world case study of the problem of using various coastal stabilization structures. It is intended to be used as a small group ...
