Icebreaker Ship Oden

Oden Cruise

The Oden Cruise is a National Science Foundation (Office of Polar Programs and the Office of International Science and Engineering) project to calibrate an ice-based detector to study the sun. It will extend the capabilities of the IceTop surface array at the South Pole that is part of the international IceCube project.

An IceTop tank inside a freezer container went from Sweden to Antarctica and back on the icebreaker Oden. The data acquisition system recorded the event rate, latitude and longitude, barometric pressure, and threshold setting for the light sensors inside the tank. Knowing the location allows the geomagnetic cutoff to be determined. This is the minimum rigidity (momentum per unit charge) that a particle needs to reach the top of the atmosphere from interplanetary space, and hence can be used to calibrate the response to low energy particles.

Three undergraduate students traveled on the Oden to help monitor the tank and assist with operations on the ship. Drew Anderson (UWRF) traveled on the first from Sweden to Montevideo, Uruguay. Samantha Jakel (UW-Rock County, UW-Madison) took over next and accompanied the tank to McMurdo Station, Antarctica. Finally, Kyle Jero (UWRF) went from McMurdo to Punta Arenas, Chile.
