Description
Summary:Following on from the successful project to recover an ice core to bedrock on Berkner Island, similar drilling equipment and logistics were used on two further projects to recover ice cores to bedrock in the Antarctic Peninsula. At James Ross Island, a ship- and helicopter-supported project drilled to bedrock at 363m depth in a single season, while a Twin Otter-supported project drilled to bedrock at 654m depth, again in a single season, from Fletcher Promontory. In both new projects, drilling was from the surface, with the infrastructure enclosed in a tent, using an uncased, partially fluid-filled, borehole.
