SWIFT-A: Shallow Water Ice Fracturing Tracking and Acoustics

DOI

A data set containing passive acoustic data from microphones, geophones and hydrophones placed on a frozen lake for 1 week. The experiment was conducted in February of 2024 on Portage Lake in the Upper Peninsula of Michigan, USA.The primary passive data is structured in 1-minute HDF5 files, each containing 8 or 11 channels of ambient ice fracture time series data recorded at 52100 Hz sample rate. The sensors were placed on/below ice ~254mm thick over water ~600mm deep. The secondary data set contains HDF5 files of in a similar structure to the first data set, but contain active impact responses in an array of locations around each acoustic sensor. Active impacts were created with a force hammer at a pre-determined set of impact locations around each acoustic array.
