This dataset comprises the geotechnical data from a series of surveys conducted in Harrison Bay, Alaska in July/August of 2021 and 2021. The contribution of this specific dataset to the overall project goals was connecting geotechnical sediment properties to erodibility parameters in an Arctic coastal environment. During the 2021 survey, geotechnical sediment properties from a portable-free fall penetrometer (PFFP) were related to physical sampling to develop a regional sediment classification scheme, and the data collected during the 2022 survey aimed to connect the results from the previous year to laboratory-based erodibility parameters from the Jet Erosion Test (JET), which was conducted on gravity core samples taken from the site. The attached repository contains both raw and processed data, and the specifics of the file structure can be found in the readMe.txt file.
