The National Science Foundation operates stations on the ice sheets of Antarctica and Greenland to investigate Earth's climate history, life in extreme environments, and the evolution of the cosmos. Understandably, logistics costs predominate budgets due to the remote locations and harsh environments involved. Currently, manual ground‐penetrating radar (GPR) surveys must preceed vehicle travel across...
This paper addresses the inherent complexity in coordinating learned behavioral strategies of multiple agents working towards a common goal. Because of the interactions among the agents, a primary challenge of policy learning is escalating computational complexity with increasing number of agents and the size of the task space (including action choices and world states). We employ an approach that...
Radar survey of the Antarctic shear zone was conducted using an ultra-wideband (2-10 GHz) frequency modulated continuous wave (FMCW) radar. The radar was mounted on a sled and pulled by a robot that was specifically designed to operate in a harsh polar environment. Our FMCW radar had good penetration through Antarctic snow and we observed snow stratigraphy to a depth of 20 m. The radar images also...
