Abstract

Summary

Buried glaciated landscapes—former glacial terrains now concealed beneath sediment or soil—pose several significant geohazards and geo-engineering constraints due to their hidden and highly variable characteristics. When developing offshore wind farms, encountering buried glaciated landscapes beneath the seafloor introduces several geotechnical and geological risks (e.g. ). These hazards can compromise the stability, safety, and cost-effectiveness of construction and long-term operation. Hazards can include the heterogeneity of the soil units; lateral discontinuity of soil units introducing uncertainty in extrapolating geotechnical responses from point-locations; and the presence of buried channels with different infill properties. In summary, many of the hazards relate to the geospatial variability in soil type, leading to variability in shear strength and response to loading. So how can we map these buried landscapes and variable soils in more detail? This paper uses examples from two previously glaciated regions to investigate how ground truthing through core logging can add another layer of detail to the traditional ground model, enabling a more detailed analysis of the geohazards posed by soil variability.
