In early September 2022, eight geologists from different disciplines across BGS completed the applied glacial geology field-based training course in north Norfolk, led by BGS\u2019s Emrys Phillips and Jonathan Lee. The course benefits geoscientists working on applied projects where glacial geology will affect ground conditions and properties of the shallow subsurface, such as offshore windfarms. <\/p>\n\n\n\n

During the course we visited Sheringham, West and East Runton, Happisburgh and Weybourne. We were able to develop skills to describe and interpret glacial sediments and deformed materials, and their influence on ground conditions both on and offshore.<\/p>\n\n\n\n\n

Day 1: Happisburgh and Weybourne<\/h2>\n\n\n\n

On the first training day, we drove to Happisburgh. We were lucky with the weather not only on the first day but also throughout the field course. With a beautiful sea view, Emrys and Jon introduced us to the topic of glacial geology and explained the history of coastal erosion at the site. At Happisburgh, we examined several cliff sections through the Happisburgh Till Member<\/a>, the Ostend Clay Member and the Happisburgh Sand Member<\/a>.<\/p>\n\n\n\n

In the afternoon we drove up the coast to Weybourne, where we encountered the Wroxham Crag Member<\/a>, which overlies Chalk Group<\/a> bedrock. The shallow marine sands and gravels of the Wroxham Crag directly overlie a brecciated chalk unit, which exhibits evidence of periglacial features such as frost heave, soft-sediment deformation and hydrofracturing.<\/p>\n\n\n\t\t\t\t
