Alert
As of midnight, December 20, 2024, the U.S. government is experiencing a lapse in appropriations. Until the situation is resolved, please refer to OPM.gov website regarding the status for federal employees. We expect the U.S. Antarctic Program to remain operational under our contractor for the foreseeable future. Should the situation change, we will post additional information on this website when it is legally permissible to do so.

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 will be performed by the science team this year. Research associate support will be provided throughout the year for routine monitoring and maintenance of equipment, to include observation of the equipment in the B2 Laboratory and V8 vault to ensure they are in normal operating mode, shutdown and restart of software and hardware, data transfer, and communication with the project's PI and other personnel as needed.
