This work explores the potential of using commercial single-beam echo sounders for accurate thickness determination of sea ice. Therefore, an own sensor system has been developed which allows to study the performance of different echo sounders monitoring sea ice under varying environmental conditions in a laboratory setup. The sensor system consists of

Influences of gas bubble and ice density on ice thickness measurement by GPR
Applied Geophysics, 2010Lake ice thickness changes with regional hydrometeorology and is closely associated with global climate change. We tested the detection of ice thickness using ground penetrating radar (GPR) in the Hongqipao reservoir. Ice crystals, gas bubbles, ice density and ice thickness were also determined by concurrently drilling for validation.

A wideband radar depth sounder for measuring the thickness of glacial ice
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004We developed a wideband coherent radar depth sounder (WCORDS) system developed to measure glacial ice thickness and map internal layers with high resolution. The radar operates over a frequency range of 50-200 MHz, providing a resolution of about 1 m in ice.

Ultrawideband Radar Measurements of Thickness of Snow Over Sea Ice
IEEE Transactions on Geoscience and Remote Sensing, 2007An accurate knowledge of snow thickness and its variability over sea ice is crucial in determining the overall polar heat and freshwater budget, which influences the global climate. Recently, algorithms have been developed to extract snow thicknesses from satellite passive microwave data.

High-resolution penetrating radar for ice thickness measurement
2012 14th International Conference on Ground Penetrating Radar (GPR), 2012We have developed a high-resolution penetrating radar to measure glacial ice thickness. With an operating frequency band of 100–150 MHz, this radar can provide a range resolution of less than 2 m in ice. The radar is designed to measure ice sheet thickness up to 3000 m.
