South Shetland Islands | |||||
King George Island | Arctowski Ice Field | −62.1203 | −58.6453 | 19/20 | King George Island (95 km long and 25 km wide, with an area of 1150 km2) is the largest of the South Shetland Islands, lying 120 km off the coast of Antarctica in the Southern Ocean. Research stations operated by Argentina, Brazil, Chile, China, South Korea, Peru, Poland, Russia, and Uruguay are located on the island, where Chile operates one of the busiest Antarctic airfields. Of the visitors who travelled with IAATO members to the region in the season 2019/20, about 6% took at least one flight in or out of King George Island, combined with a Peninsula cruise. We sampled at 8 sites on the island including at two of the three major bays (Maxwell Bay and Admiralty Bay Arctowski) as well as on Collins Glacier, which covers about 75% of the island. |

We sampled at 2 sites at Walker Bay near Hannah Point on the south coast of the island. Most of the extensive Byers Peninsula (about 60 km2), forming the west extremity of Livingston Island, is ice-free. |

Deception Island | Mount Pond | −62.9656 | −60.5522 | 19/20 | Deception Island is the caldera of an active volcano. The island has a scientific outpost with Argentine and Spanish research stations, and has become a popular tourist destination. We sampled at Mount Pond near the Whaler Bay on the southwest coast of the island and at a site nearby the Spanish Gabriel de Castilla Station. |

The glacier is the site of a blue-ice runway and two seasonally occupied camps (a Chilean camp and another operated by a private company that provides private expedition support and tours). In addition to the blue-ice runway, both camps operate ski-equipped airplanes. We sampled at two sites northwest of the Chilean camp, about 6 km east of the Blue-Ice Runway but less than 1 km away from designated landing sites for ski-equipped airplanes. |
