“…In the decades since, the label "gateway city" has been applied in numerous contexts, including in relation to immigrant gateway cities, which serve as points of entrance for migrants to the surrounding country (Knapp & Vojnovic, 2016); trade gateway cities, which provide entrance points for domestic and international commerce to an economic region (Huff, 2012); and nature gateway cities, which offer tourist point of entry to nature-based attractions such as national parks and remote areas (Line & Costen, 2017). There are gateway cities all around the world, from Jackson, Wyoming, to Rajin-Seonbong, North Korea (Jo & Ducruet, 2007;Line & Costen, 2017), but a substantial subset of the literature focuses specifically on polar, and particularly Antarctic, gateways (Dodds, 2017;Dodds & Salazar, 2021;Elzinga, 2013;Hall, 2000Hall, , 2015Leane, 2016;Leane et al, 2016;Montsion, 2015;Muir et al, 2007;Nielsen et al, 2019;Salazar, 2013).…”
