“…The Antarctic tourism industry has experienced dramatic changes during the past 50 years, growing from small and infrequent trips, such as Lars-Eric Lindblad's 57 passenger Antarctic Expedition in 1966, to an industry with more than 50,000 visitors each year (Erceg, 2017;IAATO, 2019a). Wealthy passengers, predominantly from the USA, China, Australia, Germany, and the United Kingdom, spend $3,000-$20,000 USD per person to visit Antarctica for 10-21 days between November and March, when austral summer temperatures range from −4°C to 5°C and daylight can last up to 23 h per day (Bender et al, 2016;IAATO, 2017;Jabour, 2011;Picard, 2015;Shah, 2013). These visits are called expedition tours, with landings to camp on the ice, visit historic sites, view penguin and seal colonies, and go sea kayaking, trekking, or even scuba diving (Jabour, 2011;Liggett, McIntosh, Thompson, Gilbert, & Storey, 2011;Shah, 2013).…”
