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

The instrumentation for this project is located in the B2 Lab and V8 vault. It runs continuously year-round, essentially autonomously, with only limited intervention required by personnel onsite and by the science party via the internet. No field team members will deploy this season. An onsite research associate will provide monitoring, troubleshooting, and the collection and forwarding of data as needed throughout the year.
