Dr. Brian Tucholke, 1964 delegate to NYSC from South Dakota and scientist emeritus at the Woods Hole Oceanographic Institution in Woods Hole, MA, will lead a directed study on the geological evolution of the North Atlantic Ocean, June 28-30, at NYSC.
Plate tectonics theory as developed over the past four-five decades has been a powerful tool for both explaining and predicting the structure and evolution of the earth. Dr. Tucholke said that in this directed study, delegates will:
• Survey the basic tenets of plate tectonics and investigate how they have controlled the evolution of the North Atlantic Ocean basin,
• Use geologic maps and apply general geologic principles to construct geologic cross sections from the eastern margin of North America out to the axis of the Mid-Atlantic Range,
• Examine North Atlantic basin structure, ocean circulation and sedimentation patterns from the time of initial rifting in Late Triassic time up to the present using a map-series of plate reconstructions,
• Consider the structure of North Atlantic oceanic crust and how it is created at the axis of the present Mid-Atlantic Ridge.
“Attending the NYSC as a representative from South Dakota in 1964 was a remarkable and unforgettable experience. It’s a great pleasure to return and share a lifetime of learning in geology with young and enthusiastic NYSC attendees,” Dr. Tucholke said.
