Description

This project operates instruments at South Pole Station to answer outstanding questions raised by the discovery of correlations between auroral kilometric radiation (AKR) observed 200,000 kilometers above Earth and AKR-like signals observed simultaneously at South Pole Station. The higher electron cyclotron harmonic radiation is polarized, which suggests a different and possibly nonlinear generation mechanism. These phenomena are best observed, and in most cases can only be observed, from Antarctica, making the South Pole a perfect location for this research.

Field Season Overview

No on-site fieldwork is to be performed by the science team this year. The instrument will continue to operate autonomously, year-round, via remote monitoring and control, aided by on-site support provided by ASC staff and other station infrastructure (IT network, station services, etc.) as needed.
