• Cyclic Sedimentation and Secular Variation
• Computer-based training

Peter's work on Permain strata of the world has added sections in TUnisia, but he has also gone back to his "geological roots" by working on chalks once again. For the last two years, he has been working on some Cretaceous North Sea chalks. This work hopefully will coninue during his upcoming sabbatical in Copenhage, Denmark (at the University of Copenhagen). In addition, Peter has had an opportunity to work on Cretaceous platform carbonates of Greece and Qatar. With Dana Ulmer-Scholle, Peter has also started integrating fluid-inclusion studies into his current research.

In the past 3 years, Peter has spent extensive time collecting teaching materials for SEPM (Society for Sedimentary Geology) to improve instruction in Carbonate Petrography and Sedimentology, Oceanography and Environmental Science. When the carbonate Photo CD project is completed, the CD's will cover the entire geologic record and include most of the classic outcrops from around the world.

Furthermore, Peter has started working on computerbased instructional modules for both educational and industrial users in carbonate sedimentolgoy and petrology. With Dana Ulmer-Scholle and Noel James, the first module will be an interactive guide to carbonate petrography with thousands of color photos and illustrations and even a few "rock" videos. The module is making good, but slow, progress. Another sabbatical goal is to complete the computer-generated diagrams (a very time consuming task); most of the programming has been completed. Peter has also expended considerable time and effort in putting his course materials on the Internet for easy student access. Coming soon... on-line testing so that students can judge their progree prior to exams.

Peter has had considerable experience running field trips to Florida, the Bahams, Barbados, and comparable areas. He leads a sedimentology field studies course which includes a 9-day field trip to Grand Cayman Island. Students learn the geological and biological development of Caribbean-type islands, including the formation and ecology of reefs, associated production of carbonate sediments, history of island platform developemtn, influence of human activities on island ecology, and related topics. Needless to say, this is a popular field course.
