PurposeResearch
ObjectivesJC080 was to sample the vents sites at E2 and E9 on the East Scotia Ridge, and the Kemp and Adventure craters at the southern end of the South Sandwich Islands. The sampling programme at E2 was very successful completing all the objectives assigned to that site. We found evidence of an additional vent site at E2 north. It was not possible to access the southern sites at E9 and the Kemp crater because the sites were covered in ice as a result of the very hard austral winter, although we were optimistic this would be possible before the end of the cruise. As we were about to complete the study at E2 a crew member became ill and had to be evacuated. The ship set sail to Montevideo, considered the most convenient port, which effectively ended the JC80 science programme.
