MeBo70 seabed drilling on a polar continental shelf: operational report and lessons from drilling in the Amundsen Sea embayment of West Antarctica
A multibarrel seabed drill rig was used for the first time to drill unconsolidated sediments and consolidated sedimentary rocks from an Antarctic shelf with core recoveries between 7% and 76%. We deployed the MARUM-MeBo70 drill device at nine drill sites in the Amundsen Sea Embayment. Three sites we...
