Why working as a travel guide or cruise lecturer can be an effective form of science outreach
In 2013, Sarah Aciego came up with an idea while conducting field research on glaciers in Greenland. Her mother, Mindy Cambiar, is a photographer who had accompanied Aciego to document her team’s work. The pair discussed bringing tourists to Greenland and Iceland, where Aciego could explain climate change amid dramatic landscapes. Although Aciego had tried other forms of outreach, such as public lectures, their impact felt limited. “I felt like I was just talking to the same people,” says Aciego, then a glaciochemist at the University of Michigan in Ann Arbor. Aciego and Cambiar started a travel company called Big Chill Adventures and issued a press release that resulted in a New York Times story. During the firm’s first trips in 2015, Aciego enjoyed sharing awe-inspiring spectacles, such as the Greenland ice sheet, with travellers. Aciego left her job in Michigan, and now splits her time between Big Chill Adventures and working as a flight instructor and as a part-time adjunct assistant professor for the University of Wyoming in Laramie.
Aciego recognizes that tourism can damage fragile ecosystems and produce high carbon emissions. To minimize harm, she keeps tour groups small, avoids disturbing pristine areas and teaches responsible wilderness practices such as reducing litter. And she hopes that clients leave with a greater awareness of environmental issues. Helen Giacoma, of Dallas, Texas, went to Iceland with Aciego last autumn, and was able to see for herself how far a glacier had retreated over one year. “It just hits you, how real it is”, she says. She now follows science news more closely.
Scientists have many options for outreach, ranging from making videos to giving talks. But for some researchers, nothing compares to travelling the globe to show tourists the science behind landscapes, ecosystems or the night sky. These jobs offer opportunities to see new places, revisit beloved spots and communicate to a captive audience over several days. “You’re getting paid to travel,” says Dominic Rollinson, a senior birdwatching guide at Birding Ecotours in Cape Town, South Africa.
The work isn’t a series of holidays, however. Trips can involve long hours, difficult clients and many logistical duties. Long absences from home can strain relationships with family and friends. And the pay is often modest.
The downsides haven’t deterred scientists such as Bob Jackson, founder of the travel company Geology Adventures in Ravensdale, Washington, and a former geology consultant. “It has its ups and its downs,” he says. “But it is definitely the most fun thing I’ve ever done.”
Tourism has exploded over the past few decades: the United Nations World Tourism Organization in Madrid estimates that the number of international tourist arrivals rose from 531 million to 1.3 billion from 1995 to 2017. Although statistics on science-themed tourism are sparse, signs of growth are emerging. Birding tourism has “gone through the roof” over the past decade, partly as a result of interest in citizen science and the promotion of birding events through social media, says Chris Lotz, founder of Birding Ecotours. According to the United Nations Educational, Scientific, and Cultural Organization in Paris, on average, about eight Global Geoparks — areas with international geological significance — have been established annually over the past decade, and there are currently about 140 such sites worldwide.
Tourists are seeking “a more enriching, educational travel experience”, says Tao Tao Holmes, director of trip design and operations at Atlas Obscura — a company based in New York City that runs trips and an online database about places and foods from around the world. This year, about 15% of the firm’s tours have a science or wildlife theme. Holmes says that science-themed trips regularly fill up, and clients often sign up for more afterwards.
Scientists take a variety of paths into the industry. Rollinson led day tours for a birdwatching travel company while he was a PhD student at the University of Cape Town. Lotz, whom he met through birdwatching circles, then offered him a full-time job. Jackson led geology field trips for elementary school students, and the popularity of these excursions prompted him to start Geology Adventures. He now runs trips full-time for more than 1,500 travellers each year in western North America, Spain and Australia.
Researchers can suggest ideas to travel companies. Atlas Obscura is open to proposals for trips that offer special access or knowledge, Holmes says. For instance, during a Utah trip that the company ran this year with an avian biologist, travellers got to help researchers find tiny and elusive flammulated owls. Partnering with a company can relieve a scientist-guide of some responsibilities; Atlas Obscura takes care of details such as advertising, payments and liability insurance.
Some cruise companies hire biologists, geologists or astronomers to give talks and point out natural phenomena. Ornithologist Samuel Temidayo Osinubi started working for the cruise line Silversea in Monaco, after being recommended by another lecturer. Now a postdoc at the University of Cape Town in South Africa, he spends about two months each year on cruises and has sailed around west Africa, the British Isles, the Arctic and Antarctica.
Communicating science to travellers has advantages over other outreach. People are outside their comfort zone, so the information might make a bigger impact, says Vicky Stein, who has worked as a marine biologist on whale-watching tours for Sanctuary Cruises in Moss Landing, California. And talking face-to-face makes it easier to tackle controversial issues. She says that she has had productive discussions with climate-change sceptics. “It feels like more of a real conversation,” says Stein, now a news assistant at PBS NewsHour in Arlington, Virginia. Hands-on activities can inspire children; Michael O’Clair, of Seattle, Washington, says his daughter’s interest in geology was “piqued enormously” when he took her on a mineral-collecting trip led by Jackson in 2007. She was seven years old then, and she has continued the hobby ever since.
Long trips also allow for more-nuanced discussions. Jason Goldman, a former animal-cognition researcher who is now a freelance science journalist in Los Angeles, California, and travel guide for Atlas Obscura, talks about complex conservation issues during his ecology-themed tours. “It’s a sustained, multi-day-long conversation with your audience,” he says. He hopes that the information will encourage people to change their consumer behaviour and choose responsible ecotourism operators for future trips.
Troubleshooting on trips
Travel work involves logistical drudgery. “Anything can go wrong,” says Monica Yeung, co-director of the natural-history travel company Gondwana Dreaming in Canberra. “You always have to have plan B, C and D.” A bus could break down, bad weather might derail plans or a client may need help arranging an unexpected flight home to attend to a family emergency. Guides should have local contacts to call when plans go awry, Holmes says.
Rude travellers can sour the mood. If one person clashes with the rest of the group, the guide may need to ask them to change their behaviour. “That is never fun,” Jackson says. And on the road, trip leaders get few breaks from interacting with clients. “If the customer needs you, you’ve got to be there,” Yeung says.
Scientists also must consider environmental impacts. Irresponsible tour operators can damage habitat, disturb wildlife, pollute waters and leave litter; according to one study, greenhouse-gas emissions from tourism in 2013 made up about 8% of the world’s total emissions (M. Lenzen et al. Nature Clim. Change 8, 522–528; 2018). Some guides minimize impact by keeping their distance from animals, ensuring that waste is removed and instructing travellers to avoid trampling rare plants. To reduce their carbon footprint, they might also stay in lodges with low electricity use or spend more time at fewer stops rather than drive long distances to visit lots of places. Birding Ecotours donates at least 10% of its profits to conservation initiatives and contributes to programmes that plant native trees.
It is important to ensure that as much revenue as possible returns to locals, Goldman notes. For instance, his tour groups stay at a lodge partly owned by a community in Peru. The hope is that tourism will generate an economic incentive for locals to protect wildlife from poaching and the land from other uses, such as mining, logging or agriculture.
Although some guides earn good wages, the work generally isn’t lucrative. Jackson says that he makes a comfortable living, but it took about three years for his company to bring in enough money to support himself full-time. Aciego’s annual income from her travel company, which occupies about two-thirds of her time, is about half of what she earned as a full-time professor. A starting salary for a scientist joining a travel firm would be slightly less than a postdoc’s, and part-time guides earn about US$100–250 a day, Rollinson estimates. For cruise lecturers, Osinubi says that $50–200 a day is typical.
And scientists must consider time spent away from home. “The travel is wearing,” Aciego says. The job might be difficult for parents; guides tend to be in their 20s and 30s, and those who stay longer often transition to roles with less travel, such as management, Rollinson says. In some cases, scientists might be able to bring family members. Osinubi knows a couple who work as lecturers on cruises together; some cruise lines might allow researchers to bring close family members for limited periods.
Researchers who don’t want a full-time travel career can dabble in one (see ‘The travel bug’). They could lead day tours at the weekend or longer trips during the summer. Rollinson says his PhD supervisors did not mind his travel guiding as long as he met research deadlines. Through the website ToursByLocals, scientists can apply to guide travellers who are visiting their area, and specify when they are available to give tours. Researchers who are already flying to a remote locale for fieldwork could tack on a nearby trip.
Although being a part-time travel guide might take time away from research, Aciego argues that it is a valid form of science communication. And the work might inform studies. For instance, Osinubi has seen cruise lecturers collect data on animal populations during voyages. Travel guides can build close relationships with locals, who could notify researchers later about environmental changes, Aciego says.
Sharing their knowledge with curious guests often reignites researchers’ passion for the subject. Jackson recalls his clients’ amazement when he brought them to a mine littered with pyrite crystals in Spain. “I can’t even describe how enthused they are,” he says. “That wonder that they experience for the first time — I just feed on that. It’s a great feeling to be able to do that for people.”
