Experiments with particle settling part of Cutting Edge:Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
In this activity, students experiment with the effects of Reynolds numbers (viscosity), particle shape, and particle concentration (flocculation) on settling velocity.
Sediments and the Global Carbon Cycle part of Cutting Edge:Sedimentary Geology:Activities
This is a series of exercises designed to introduce undergraduate students to the role of sediments and sedimentary rocks in the global carbon cycle and the use of stable carbon isotopes to reconstruct ancient sedimentary environments. Students will make some simple calculations, think about the implications of their results, and see an optional demonstration of the density separation of a sediment sample into a light, organic fraction and a heavier mineral fraction.
Exploring sea level change in Google Earth part of Cutting Edge:Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
This is a short activity that uses Google Earth to explore sea-level change as measured by tidal gauges around the world
Exploring Barrier Islands in Google Earth part of Cutting Edge:Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
This is an exploration in Google Earth of the links between barrier island morphology and wave and tidal energy.
Sediment production and distribution across the margins part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
The aim of this exercise is for students to explore the relationships among tectonics, sediment production, oceanographic forcing, coastal morphology, and sediment accumulation at the margins. The students will receive data on the size, runoff, and sediment discharge of a suite of watersheds, including the Amazon, Columbia, Eel, Fly, Mississippi, and Waipaoa. Students will use GeoMapApp 2.0 to locate the watersheds, characterize their tectonic settings, collect additional data on watershed relief and coastal morphology. Their task will be to compare these twelve systems and to draw conclusions about the factors that explain their differences .
Quantification of Critical Shear Stress part of Cutting Edge:Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
This is a lab activity designed to give students experience with the concept and quantification of critical shear stress.
Marine Sediment Transport part of Cutting Edge:Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Courses
This course is designed as an introduction to the theory and reality of sediment transport in the marine environment. The course includes both lectures and laboratory experiments that investigate the processes that control the settling of sediment grains through fluids, the erosion of sediment grains from the seabed, the transport of sediments as suspended load and bedload, and the formation and migration of bedforms such as ripples and dunes. In addition to covering the basic physics that governs these processes, the course reviews real-world complications, how sediment transport measurements are made in the field, and case studies of sediment transport in particular marine environments, from estuaries to the deep sea.
