Estimating Exchange Rates of Water in Embayments using Simple Budget Equations. part of Quantitative Skills:Activity Collection

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.

Is There a Trend in Hurricane Number or Intensity? part of Cutting Edge:Topics:Hurricanes-Climate Change Connection:Activities

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 ...

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples

Module by Peter LaFemina, Penn State, State College, PA. This cover page by Ali Furmall, University of South Florida, now at University of Oregon.

SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.

Porosity and Permeability of Magmas part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples

chuck connor

SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

What is the Relationship between Lava Flow Length and Effusion Rate at Mt Etna? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples

chuck connor

SSAC Physical Volcanology module. Students use Excel to determine a log-log relationship for flow length vs effusion rate and compare it with a theoretical expression for the maximum flow length.
