Abstract:
The Automated Meteorology - Ice - Geophysics - Ocean observing Systems are a series of multi-sensor stations that have been employed for in situ data gathering in support of polar research since 2009, with multiple installations on the Antarctic Peninsula, the Nansen Ice Shelf, and on Thwaites Glacier's eastern ice shelf. The station series have been optimized for weather data collection and near-surface glaciology (AMIGOS-I) and later augmented with sensors for measurements related to ice-ocean interaction and internal ice sheet temperature profiling (AMIGOS-II and -III). The stations are powered by a solar + battery system, and provide real-time data through an Iridium uplink. The stations include cameras, weather instruments, thermistors, and GPS sensors, with later versions including ocean instruments (CTDs and doppler current meters) and a Distributed Temperature Sensing (DTS) fiber optic system. We present an overview of the instrument, past data from earlier installations, and a summary of the data sets and results from the two AMIGOS-III units installed on the Thwaites Glacier ice shelf.
