Antarctic Circumnavigation Expedition was a coordinated scientific voyage encircling Antarctica during 2016–2017 that brought together researchers, institutions, and non-governmental organizations to study the Southern Ocean, Antarctic ecosystems, and the effects of climate change on polar environments. The expedition integrated expertise from polar research stations, universities, conservation groups, and intergovernmental bodies to conduct multidisciplinary studies from the Antarctic Peninsula to the Ross Sea and across the Weddell Sea.
The expedition emerged from collaborative initiatives among Scientific Committee on Antarctic Research, International Union for Conservation of Nature, BirdLife International, Convention on the Conservation of Antarctic Marine Living Resources, Commission for the Conservation of Antarctic Marine Living Resources and research programs linked to National Science Foundation (United States), British Antarctic Survey, French Polar Institute Paul-Émile Victor, Australian Antarctic Division, Alfred Wegener Institute, and National Institute of Polar Research (Japan). Motivations included accelerating baseline data collection influenced by findings from the Intergovernmental Panel on Climate Change reports, addressing recommendations from the United Nations Environment Programme and supporting policy processes under the Antarctic Treaty System and the Convention on Biological Diversity. Scientific drivers referenced earlier voyages such as Endurance Expedition (1914–1917), Discovery Investigations, and modern campaigns like the Southern Ocean Observing System and the International Polar Year.
The circumnavigation traced a course through the Drake Passage, along the Antarctic Peninsula, around the Weddell Sea, across the East Antarctic, and into the Ross Sea before returning via the Amundsen Sea and Bellingshausen Sea. Key ports of call and logistic links included Ushuaia, Punta Arenas, Stanley, Falkland Islands, Cape Town, and Hobart. The schedule coordinated with windows for access near McMurdo Station, Rothera Research Station, Mawson Station, Palmer Station, and field camps established under Scientific Committee on Antarctic Research protocols. Navigation referenced charts from the International Hydrographic Organization and satellite support from Copernicus Programme, Landsat, and Sentinel satellites.
Primary platforms featured ice-strengthened research vessels including former Soviet research ships such as RV Akademik Sergey Vavilov and RV Akademik Ioffe, outfitted with laboratories from institutions like Scripps Institution of Oceanography, Lamont–Doherty Earth Observatory, British Antarctic Survey, Australian Antarctic Division, and Scientific Committee on Antarctic Research member labs. Equipment included CTD rosettes tied to protocols by the Global Ocean Observing System, autonomous platforms such as Argo floats, unmanned aerial systems akin to platforms used by National Oceanic and Atmospheric Administration, underwater gliders similar to Seaglider, and long-term observatories inspired by Southern Ocean Observing System moorings. Shipboard suites integrated echo-sounders and multibeam systems calibrated against standards set by the International Hydrographic Organization.
Research objectives encompassed marine biology surveys building on work from Discovery Investigations and CCAMLR data, oceanography aligning with Argo and Global Ocean Observing System goals, physical climatology informed by Intergovernmental Panel on Climate Change assessments, and biogeochemical cycling connected to studies by Woods Hole Oceanographic Institution and Monterey Bay Aquarium Research Institute. Activities included plankton net tows used in protocols from Longhurst Biogeographical Provinces, marine vertebrate surveys aligned with methods from BirdLife International and IUCN Red List of Threatened Species, sea-ice thickness measurements comparable to CryoSat missions, and carbon export studies building on Joint Global Ocean Flux Study. Collaborations engaged researchers from University of Cambridge, Massachusetts Institute of Technology, University of Tasmania, University of Otago, University of São Paulo, P.P. Shirshov Institute of Oceanology, and National Institute of Polar Research (Japan).
Operations complied with the Protocol on Environmental Protection to the Antarctic Treaty and risk frameworks from the International Maritime Organization for polar code navigation. Pollution prevention followed standards from the MARPOL convention and biosecurity measures mirrored guidance from the Committee for Environmental Protection and Scientific Committee on Antarctic Research to limit non-native species transfer. Emergency response planning coordinated with United States Antarctic Program logistics, Australian Antarctic Division search-and-rescue protocols, and port-state contingency arrangements in Cape Town and Ushuaia. Safety equipment met recommendations from International Association of Classification Societies and satellite communications relied on networks associated with European Space Agency and Inmarsat.
The circumnavigation built on a lineage of polar voyages including the James Clark Ross expedition, Discovery Investigations, Endurance Expedition (1914–1917), mid-20th-century Operation Highjump, and scientific eras marked by the International Geophysical Year and International Polar Year (2007–2008). The 2016–2017 campaign itself coordinated legs that involved partnerships with Scientific Committee on Antarctic Research working groups, BirdLife International seabird observers, IUCN specialists, and national programs from Argentina, Chile, United Kingdom, United States, Australia, Russia, Japan, South Africa, and South African research stations. Follow-up cruises referenced planning workshops at institutions such as Scott Polar Research Institute and policy briefings at International Maritime Organization and United Nations Environment Programme forums.
Findings informed conservation proposals submitted to Commission for the Conservation of Antarctic Marine Living Resources including considerations for marine protected areas inspired by earlier designations in the Ross Sea Marine Protected Area and research cited by the Antarctic Treaty Consultative Meeting. Data contributed to assessments by the Intergovernmental Panel on Climate Change, biodiversity evaluations for the IUCN Red List of Threatened Species, and implementation guidance for the Protocol on Environmental Protection to the Antarctic Treaty. The expedition strengthened networks among Scientific Committee on Antarctic Research, Commission for the Conservation of Antarctic Marine Living Resources, BirdLife International, IUCN, and national polar programs, influencing stewardship debates at the United Nations Environment Programme and regional engagement with port authorities in Hobart and Cape Town.
