Two acoustic datasets collected on a frozen shallow freshwater lake during March of 2023 are included. This collection took place over one full week on Portage Lake in the Upper Peninsula of Michigan, USA. The first dataset consists of ambient ice and environmental noises collected by an array of hydrophones, microphones and geophones placed below, above and on the ice respectively. The second dataset consists of instrumented force hammer impacts at a series of locations on the the ice with the corresponding response at each acoustic sensor. Corresponding local weather data is also provided. These two data sets offer a rich look into the physics of ice cover movement, response to weather phenomena, shallow water and ice cover waveguide acoustic propagation and ice sheet response to weather. The datasets consists of raw time series data from all sensors, array dimensions and placement and hardware descriptions.
