Installed during the 1959-60 field season, the Cosray Lab is the longest continually running experiment in the U.S. Antarctic Program. This 56-year data set plays a crucial role in understanding the nature and cause of cosmic ray and solar terrestrial variations occurring over the 11-year sunspot cycle, 22-year Hale cycle, and longer time scales. Neutron monitoring provides a three-dimensional perspective of the anisotropic flux of cosmic rays that continuously bombard Earth. The data acquired by this research project will advance the understanding of fundamental plasma processes that occur on the Sun and in interplanetary space. Researchers will analyze data acquired on station, in concert with data from the "Spaceship Earth" neutron monitor network, to understand variations associated with solar energetic particles that occur on time scales of minutes to hours. The observations will also assist space-weather forecasting and specification.

Field Season Overview

Team members will deploy to McMurdo station where they will implement their retrograde plan for this project. There are two distinct components to the plan for this season: (1) Crating and packing the remaining two sections of the neutron monitor into shipping containers for transport to Christchurch, New Zealand, where they will be held for pickup by collaborators from the Korean Antarctic Program; (2) Crating and packing equipment for retrograde to the continental United States.
