Antarctica has never had a native people, yet it has more than twenty thousand place names, almost all given in the last two centuries by two dozen nations at once. I mapped 20,151 of them: who named each one, when, and after whom.
Every other continent was named by the people who lived on it, over thousands of years, in languages long since lost. Antarctica was named in a hurry, by strangers, mostly within living memory. Sealers and naval expeditions gave the first names in the 1820s and 1840s; the explorers of the heroic age added more; and then, from the 1940s, aircraft photographed the interior and survey teams found tens of thousands of mountains, glaciers and nunataks that needed something to be called. The names went to the people who were there, to the people who paid, to ships and aircraft, to kings and queens, and sometimes to what a rock looked like.
The Scientific Committee on Antarctic Research (SCAR) keeps a Composite Gazetteer of Antarctica that brings together the national lists of 25 countries: 39,187 names for 20,151 features once the same feature listed by several countries is counted once. Most entries carry a short narrative that says who named the feature and after what. I read those narratives with a set of rules, checked them by hand where it mattered, and linked the people to Wikidata to find where they were born. The question is simple. Whose continent is it, on the map?
Each dot is a named feature, coloured by the nation that named it. Pick a nation to see only its names, or colour by what the features are named after. Click any dot for its story; the map on the right shows where the person it honours was born, when Wikidata knows.

Coast and ice shelves from OpenStreetMap via OpenFreeMap; grounded ice from Natural Earth. Claims are the seven national sectors frozen by the Antarctic Treaty; the Antarctic Peninsula is claimed by Argentina, Chile and the United Kingdom at once. Birthplaces from Wikidata, for the 1,998 features whose Wikidata entry names a person.
The United States named 5,253 features (26%), most through its Advisory Committee on Antarctic Names, which since 1947 has named the features found by American aircraft, ships and field parties. The United Kingdom named 3,981 (20%), above all through its Antarctic Place-names Committee and the surveys of the Falkland Islands Dependencies Survey and the British Antarctic Survey on the Antarctic Peninsula. Then come Norway (1,590), Bulgaria (1,534), Australia (1,442), New Zealand (1,368) and Russia (1,292).
Features named by each nation

A name in a country's gazetteer is not always that country's name. The SCAR gazetteer holds 39,187 entries because most features are listed by several countries: 59% appear in more than one national list. The Russian list, for example, holds 4,808 entries, most of them transliterations of names given by others. I count each feature once, for the nation that named it first. For 10,831 features the narrative says who named it; for 6,397 only one national list holds the feature; for 1,559 I take the expedition the narrative says discovered or charted it; for 956 the list that approved it first, the weakest of these rules; 401 remain unknown. I read the attribution of every land, coast, sea and ice shelf by eye and corrected 7.
Seven countries claim slices of Antarctica, frozen but not given up under the Antarctic Treaty of 1959. Naming a place has always been a way of saying it is yours, and the claimants mostly name inside their own claims: 99.5% of Argentina's names, 96% of Australia's and 80% of Norway's lie in their own sectors. But they do not name most of what they claim. Australia named 38% of the features in the Australian Antarctic Territory and Norway 56% of Dronning Maud Land. The United States, which claims nothing, named 48% of the features in New Zealand's Ross Dependency and 96% of unclaimed Marie Byrd Land. On the Antarctic Peninsula, claimed three times over, Britain named 41% of the features inside the Argentine claim, and Argentina only 5.5%.
Who named the features inside each claim
Features inside each national sector by the nation that named them. The three Peninsula claims overlap. Undersea features (254) are left out, and the 59 features of Peter I Island count with Norway's claim. Hover a block.
Only 148 of the dated names carry a date from the heroic age of exploration (1897 to 1922), the era of Amundsen, Scott, Shackleton and Mawson, though many more were given then and are dated here by a later approval. The flood came later. After the Second World War, aerial photography from American, British, Norwegian and Australian expeditions revealed whole mountain ranges, and the International Geophysical Year of 1957 to 1958 put permanent stations on the continent. Between 1960 and 1979 7,472 features were named, 43% of all dated names; the busiest decade was the 1960s with 5,384. Naming has not stopped: 18% of dated names were given in 2000 or later, 48% of them by Bulgaria.
Names given in each decade
Features by decade of naming, stacked by the naming nation. The year is the one in the naming statement where the narrative gives it, otherwise the first approval by a national committee. Hover a column.
For 16,354 features (81%) the narrative says what the name means. Of those, 57% honour a person, 18% describe the place (its shape, colour or something that happened there), 6% are named after a place elsewhere, 5% take the name of a nearby feature and 3% honour a ship. Nations name very differently. 83% of American names whose origin is recorded honour a person, and 53% of British ones. Norway and Japan describe: 61% of Norwegian names and 86% of Japanese ones are descriptive, like the Norwegian Skakktoppen (the crooked peak) or the Japanese Mikazuki Iwa (crescent rock). Bulgaria, which began naming in earnest in the 2000s, names after home: 57% of its names are towns, villages, rivers and mountains in Bulgaria.

The people on Antarctica's map are not mostly famous. The commonest surnames among the features named after a person are Smith (35), Davis (23), Brown (22), Johnson (21) and Wilson (19), because the American and British committees honoured the people who did the work: the scientists, the surveyors, the aircrew and the station staff. Reading what the narratives say about each person, 33% were scientists or surveyors and 18% naval or military personnel. 30% of the people on American names served in the US Navy or another service, mostly in the air squadrons of Operation Deep Freeze; 25% of the people on Australian names were station staff such as cooks, radio officers and weather observers. Bulgaria honours its own history: 18% of its people are tsars, khans and politicians, and 13% writers, artists and composers.

Wikidata links 1,998 Antarctic features to 1,772 people, 1,449 of them with a known birthplace. 74% were born in Europe and 17% in North America; Oceania has 66, Asia 33, South America 18 and Africa 7. By modern country the United Kingdom leads (307), then the United States (239), France (166) and Norway (132). Some nations look abroad more than others: of the people on British names with a known birthplace, 40% were born in the United Kingdom, against 81% of the people on Norwegian names born in Norway. The most honoured in Wikidata are Roald Amundsen (8 features), Ernest Shackleton and Douglas Mawson (7 each).

Of the 9,353 features named after a person, 315 honour a woman (3.4%). They include some of the biggest names on the map: Queen Maud Land, Victoria Land, Marie Byrd Land and the Ronne Ice Shelf. But until recently the women on the map were there because of whom they were related to. Of the women honoured in names given before 1990, 64% were queens, princesses, wives, daughters, mothers or sisters of explorers and patrons. Since 1990 the share of women among people honoured has risen to 10.3%, against 1.9% before, and most of them are scientists and support staff honoured for their own work, from the glaciologist Julie Palais to the geologist Margaret Bradshaw: only 6% are relatives or royals.

Before 1990, nearly two in three of the women on Antarctica's map were there as someone's wife, daughter or queen.
Most features in several national lists share one name, translated or transliterated: the Bellingshausen Sea is the Mar de Bellingshausen in Spanish and Bellingshausenhavet in Norwegian. But 1,038 features (8.7% of those listed more than once) carry names that differ by more than spelling or transliteration in different lists. Some are translations (the Seal Nunataks are the Robbeninseln in German and the nunataks Foca in Argentina's list); many are genuinely different names, mostly on the Antarctic Peninsula, where Argentina and Chile kept their own names for features Britain had named.

Data. The SCAR Composite Gazetteer of Antarctica, as served by the Australian Antarctic Data Centre: 39,187 names in 25 national gazetteers, plus undersea features named through the GEBCO undersea names committee. Names of the same feature share a common identifier; I count 20,151 features after merging 8 pairs of identifiers that hold the same name at the same place. People and birthplaces come from Wikidata (CC0): features with coordinates in Antarctica and a "named after" statement, matched to the gazetteer by name within 25 km (86% of Wikidata's Antarctic features matched).
Reading the narratives. The naming nation, the naming year and what each feature is named after are read from the narratives by rules (published with the code): the phrase "named by" gives the committee, expedition or leader, mapped to a nation; the words after "named for", "named after" or "in honour of" give the honoree, sorted into a person, a ship, a place elsewhere, a description and so on. A first random audit of 100 features found about one in ten misread; after improving the rules a second audit of 60 found 7 faults, which are fixed. An independent review then read the doubtful classes again and corrected 196 more readings (mostly people filed as "other"), found 106 women the first pass had missed and removed 5 wrong Wikidata links; some people remain in "other", so the share of people is if anything an underestimate. Every possible woman (from titles, relatives, given names, Slavic surnames and Wikidata's sex) was read by hand: 368 candidates, 315 confirmed. Features named after a couple or a family are not counted as honouring a woman. 21 Wikidata birthplaces that are only a country or state are left off the map. Countries of birth are modern (Natural Earth). In the source, 226 British approval dates of 2001 to 2010 are stored a century early (1901 to 1910); I corrected them.
Caveats. The narratives vary by country: the American, British, Australian and New Zealand ones are full, while many Russian, Argentine and Chinese entries have no narrative in English or none at all, so 19% of features have no recorded meaning. The naming year is often the year a committee approved a name rather than the year it was first used, which pulls older names into the 1940s to 1960s. Claims are drawn as longitude sectors; undersea features (254, SCAR's sea-floor class) are counted as features but left out of every claim share. Wikidata covers only some of the people. Some readings will still be wrong; the data file lists the rule-based reading and the text it came from for every feature, so that anyone can check.
