title = "Dual-Frequency Radar Measurements for the Swida-Rings Mission: Circumventing Antarctica to Map Its Grounding Line",
abstract = "We present a dual-band radar instrument package for measurements during the SWIDA-RINGS mission {\textendash} a large international scientific collaboration to circumvent Antarctica and collect new airborne data along the continent{\textquoteright}s grounding line {\textendash}. The radar instrument package consists of a \textasciitilde{}30-MHz radar depth sounder for ice thickness measurements and a microwave radar with multi-gigahertz bandwidth for mapping seasonal snow accumulation. We integrated the radar electronics and antennas onto a Twin Otter aircraft equipped with a gravimeter, a scanning lidar, optical cameras and an atmospheric sampling apparatus. This unique instrument combination will provide critical data to fill knowledge voids on the Antarctic Ice Sheet margins and general dynamics. This paper provides a brief overview of the SWIDA-RINGS mission and its objectives; a description of the dual-band radar instrument setup and aircraft integration efforts; and sample preliminary radar results from a logistically complex field campaign conducted in Antarctica during the 2024/2025 Austral Summer season.",
