In-situ Density from Gravity by Nettleton part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Scott White, University of South Carolina-Columbia
This activity develops students' understanding of gravity data corrections and density estimates by using a gravimeter to collect data and then interpret this data to find an estimate for the local bulk ...

Sequenced writing assignment part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Steven Jaume, College of Charleston
An iterative term paper where students include new geophysical data in each new version. This allows the instructor to work closely with the student and point out how different geophysical datasets constrain ...

Gravity and Magnetic Consulting Project part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Lawrence L. Malinconico, Lafayette College
This project involves the design, implementation, data collection, analysis and report writing for gravity and magnetic survey conducted over a two month period during the course.

Estimating Valley Fill Thickness with a Gravity Survey part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Bill Witte, University of Alaska Fairbanks
We will make a gravity traverse of the Goldstream valley to determine the thickness of the valley fill. The exercise will take ~ 4hrs, working in two teams all students will get to function in each of the survey ...

Equation Dictionary part of Workshop 07:Geophysics Activities
Jackie Caplan-Auerbach, Western Washington University
The equation dictionary is an expansion of the traditional notecard that students bring to equation-based tests. It requires them to provide a prose explanation for the processes described by an equation as well as ...

Concept puzzles about geophysical methods part of Workshop 07:Geophysics Activities
Sarah Titus, Carleton College
These exercises can be used in class to insure students have a firm grasp on the concepts behind a variety of geophysical techniques and can take anywhere between 10-45 minutes.

Density structure of the earth from mass and moment of inertia part of Workshop 07:Geophysics Activities
Donald Forsyth, Brown University
Using mass and moment of inertia as constraints, students construct density models of the whole earth. This activity uses concepts from physics, multi-dimensional calculus, and linear algebra, and also reinforces ...

Geophysics in the community part of Workshop 07:Geophysics Activities
Jackie Caplan-Auerbach, Western Washington University
In this activity students develop independent or small group research projects in collaboration with local community organizations, or with the goal of investigating a topic relevant to the greater community. This ...

Measuring the Gravity Field: "The Stairwell Lab" part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Samuel Peavy, Georgia Southwestern State University
This lab teaches the student how to use a gravimeter by measuring gravity in a stairwell. A plot of the data set will yield and estimate of the elevation correction.

Free-Air Gravity part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
, Louisiana State University, Baton Rouge
Students use gravity measurements to estimate the height to the top of a platform in the Howe-Russell Attrium. This assignment is used to show the precision of gravity measurements and the Free-Air correction

Digital Analysis of Geophysical Signals and Waves/Digital Recording part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
George Jiracek, San Diego State University
Sampling (digitizing) of geophysical data is explained using animations by multiplications in the time or space domains by Dirac combs and boxcar functions. Pitfalls in this process can render digital data totally ...

Digital Analysis of Geophysical Signals and Waves (DAGSAW)/Filtering part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
George Jiracek, San Diego State University
Filtering is one of the most important steps in geophysical data recording and processing since it is present in all geophysical analysis. Filtering is explained in the Digital Analysis of Geophysical Signals and ...

The gravitational attractive force of the English Dept. part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Bill Witte, University of Alaska Fairbanks
By measuring the gravitational force in the basement and on the roof of the Gruening Bldg. students will determine the gravitational attraction of the building and its contents and estimate the mass of the ...

Atlantic City Mapping Project part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Peter Knoop, University of Michigan-Ann Arbor
The Atlantic City project combines magnetic and gravimetric surveys with standard geological field mapping techniques. Lack of outcrops and Banded Iron Formations (BIFs) are a key features of the mapping area, and ...

Measuring the vertical gradient of gravity part of Cutting Edge:Courses:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Rob Sternberg, Franklin and Marshall College
The free-air effect tells us that as elevation above sea level increases, gravitational acceleration g decreases at the rate of about 0.3086 mgal/meter. This effect is routinely corrected for when making gravity ...

Skill puzzles part of Cutting Edge:Courses:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Sarah Titus, Carleton College
These are short exercises that allow students practice with concepts in Structural Geology, Tectonics, or Geophysics. (Many of them were designed with Eric Horsman.) The basic idea is to give students opportunities ...

New Views of an Old Continent: A Tectonics Lab Exercise Using Geophysical Maps of Australia part of Cutting Edge:Courses:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
David Greene, Denison University
In this lab activity students are given five different map views of the continent of Australia: Geology, Gravity Anomaly, Magnetic Anomaly, Digital Elevation, and Satellite Image, and asked to investigate and ...

Lithospheric flexure in Hawaii part of Cutting Edge:Data, Simulations and Models:Activity Ideas
Andrew Goodwillie, Kim Kastens, Linda Sohl, Jaime Toro, Amy Cline, Shelley Olds, Rob Graziono, Sarah Titus, Erin Heffron, Chuck Anderson, Jim Washburn, Steve Reynolds, Ron Schott, and Charlie Onasch Topic: ...
