Formerly glaciated landscapes are extremely complex, variable, and notoriously challenging to interpret on the present-day land surface, let alone in the shallow subsurface in offshore environments. The East Irish Sea Basin (EISB) has been a focal point for offshore Renewable Energy for the last 15 years and offshore wind developments have provided geoscience data in abundance. In 2021, a joint venture (JV) between bp Alternative Energy Investments Ltd (“bp”) and Energie Baden-Wurttemberg AG (“EnBW”) were awarded two lease areas in the East Irish Sea during the Offshore Wind Leasing Round 4. The area is challenging from a geological perspective as it was significantly affected by the Last Glacial Maximum (LGM). High-quality 3D Extremely High-resolution (EHR-3D) geophysical and geotechnical data have been acquired to better characterise the nature of the glaciated soils. This paper highlights some of the subsurface expressions of this formally glaciated landscape and discusses the challenges and uncertainties, even when the latest remote sensing technology and interpretation techniques are available.
