Australia will evacuate 24 Macquarie Island expeditioners in October to avoid the psychological and operational impact of a potential bird-flu outbreak near a large elephant-seal colony, with the RSV Nuyina set to retrieve the team and remote monitoring planned; the roughly $370m station rebuild is temporarily slowed but long-term Antarctic presence will continue.
Two remote locations reveal mantle rocks at the surface: Macquarie Island, where ongoing plate motion brings oceanic mantle-derived rock to the surface at an active boundary, and Gros Morne National Park’s Tablelands, where an ancient ophiolite block places upper-mantle rocks atop continental crust—each site representing different tectonic settings and timescales, with Macquarie remaining remote and heavily bio-secured and Gros Morne playing a historic, foundational role in plate tectonics research.
