A 400 Ky x-axis time limit is used in order to view the big picture of all of the cycles. The red arrow is pointing at a cycle occurring at 100 Ky. The blue line represents the data with an 82,516-year interval. The red line represents the data with a 92,516-year interval. The green line represents the data with a 102,516-year interval. Chart Description automatically generated Fourier plot of the delta MS data showing peaks of interest for determination of cycles. A 25 Ky x-axis time limit is used in order to pick out both precession and sub-precession cycles. The red arrows are pointing to cycles occurring at 7 Ky 10-11 Ky and 19-21 Ky. The blue line represents the data with an 82,516-year interval. The red line represents the data with a 92,516-year interval. The green line represents the data with a 102,516-year interval. Chart, line chart Description automatically generated Fourier plot of the delta MS data showing peaks of interest for determination of cycles. A 3.5 Ky x-axis time limit is used in order to view the fine scale sub-precession cycles. The red arrows are pointing to cycles occurring at 2.0-2.05 Ky and 3.2-3.3 Ky. The blue line represents the data with an 82,516-year interval. The red line represents the data with a 92,516-year interval. The green line represents the data with a 102,516-year interval.

The idea is that you learn more about the United States, you get to work on your English skills; I get to learn more about Czechia and take this information back to the US, develop Czech language skills, and work with Dr. Kumpan as well as others on collaborative research projects. Who are you? What the class is about – Cyclic Stratigraphy and Astrochronology This course will review and discuss cyclic processes in the stratigraphic record and methodology for interpretation of the duration of the different cycles: Sloss super cycles, First, Second, and Third order sequences - global tectonics; Milankovitch cycles - orbital perturbations; Millennial-scale cycles - orbital perturbations and climate dynamics; and smaller scale cycles. This is a dynamic topic with relevance from Holocene to Archean climate, hydrological, and depositional studies that has implications in all aspects of sedimentary geology as the changes in climate have an impact on the distribution of organisms, weather patterns, and generation of clastic particles.

At our next meeting we will discuss these articles and then plan for the rest of the semester which will involve assigning when you will be in charge of discussion.
