Earthquake Location part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Earthquake location is an interesting and significant aspect of seismology. A number of methods that vary from simple to complex are available for learning about earthquake location. The methods also allow connections to other important concepts in seismology and provide a variety of approaches that address different learning styles and can be used for reinforcement and assessment.
Field Geophysics Sampling and Aliasing Theory and Examples part of Cutting Edge:Geoscience in the Field:Activities
Collecting geosciences data in the field involves sampling in time and space. Sampling includes theoretical limitation and the possibility of aliasing which has severe effects on sampled data. The concepts are applicable to spatial sampling and geological data. The discussion is most appropriate for classroom or computer laboratory use prior to field data collection.

Vibroseis Correlation - An Example of Digital Signal Processing part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
In the vibroseis method of seismic exploration, the seismic energy source (ground vibration controlled by shaking the mass of the vibroseis truck) is distributed over a time of several seconds. To see how vibroseis recording and processing works, we will look at the mathematics of vibroseis signal processing in both the time and frequency domains and view illustrations of the recorded and processed signals.
Supporting Minority Students at Purdue University-Main Campus part of Integrate:Programs:Supporting Minority Students
The majority of undergraduate students at Purdue University are from Indiana (57%) or surrounding states in the mid-west. Also, international students make up 17% of the undergraduate enrollment. The mid-western states have the lowest percentage of minority population of any region in the United States. Below are some statistics (2013-14) for undergraduate enrollment of the university. Purdue undergraduate enrollment: Male 16,843 (57.2%) Female 12,597 (42.8%) Purdue undergraduate minority enrollment: 16% of all undergraduates 19.4% of all U.S. undergraduates Purdue undergraduate underrepresented minority (URM) enrollment: 8.5% of all undergraduates 10.2% of all U.S. undergraduates Within Purdue's College of Science, there are 3319 undergraduates of which 2164 (65.2%) are male and 1155 (34.8%) are female. Demographic data for the Earth, Atmospheric, and Planetary Sciences (EAPS) department are shown below: EAPS undergraduate majors (2013-14) Male 70 (60.9%) Female 45 (39.1%) International students 12 (10.4%) Minority students 13 (11.3%) There are six undergraduate major programs within EAPS: Atmospheric Science/Meteorology, Geology and Geophysics, Environmental Geoscience, Planetary Science, Earth and Space Science Education, and Interdisciplinary Science (joint with other departments in the College of Science). The EAPS department was founded in 1967 in order to increase the coverage of science programs within the College of Science, provide degree programs in Earth and atmospheric sciences, and in recognition of the significance of the geosciences to societal issues into the future. The department was originally named the Department of Geosciences. The name was subsequently changed to the Department of Earth and Atmospheric Sciences and then to the Department of Earth, Atmospheric, and Planetary Sciences. There has been significant change in the EAPS demographics in the past 5 years. The percentage of female undergraduate students has increased from 27.2% in 2009-10 to 39.1% in 2013-14. Similarly, the percentage of international students has increased from 4.4% to 10.4%, and the percentage of minority students has increased from 5.2% to 11.3% in the same time period.
