And he leads by example.
This summer, Boss and UMaine master's graduate Thomas Leeuw will board Tara — a sailboat for the planet — to collect data and conduct research in the Mediterranean Sea. They'll study the ocean color, composition and pigments of surface particles.
And in addition to collaborating with international scientists, they'll talk with schoolchildren about the ocean, swim in warm aqua water and eat delicious meals with backdrops of beautiful Mediterranean vistas.
“It's a wonderful career,” Boss says. “You should do something you're passionate about,” he says. “You can be serious about science and have fun in the process.”
Boss finds the work and play aboard Tara so valuable and fun, he's gearing up for his third voyage. In August, he'll be one of the scientists aboard during the 10-day leg from Israel to Malta. Boss, who participated in water sports growing up in Israel, says he's most comfortable in the water and knew from an early age he wanted to pursue a career in oceanography.
Tara is three months into its seven-month, nearly 10,000-mile 2014 international expedition that includes stops in 11 countries, including France, Greece, Israel, Italy and Spain. Tara departed in May from Lorient, a seaport in northwestern France, and is scheduled to return in December.
During the trek, a host of other scientists are exploring the impact of plastic on the Mediterranean ecosystem and the degree to which microplastics in the ocean are part of the food chain. Researchers also seek to raise awareness about the Mediterranean's environmental issues and encourage policymakers in the region — where approximately 450 million people live — to develop better waste management plans.
At each stopover, the team that generally includes five sailors, two scientists, a reporter and an artist — invite the public to tour the 118-foot-long, 33-foot-wide, 120-ton research vessel. And they take part in outreach projects. May 31 on No Tobacco Day, for instance, crewmembers of Tara removed 53 gallons of trash, including cigarette butts, from a beach.
French designer Agnes B. founded the nonprofit Tara Expeditions in 2003 to “understand the impact of climate change and the ecological crisis facing the world's oceans,” according to its website.
Boss says the mission, outreach, interdisciplinary science, sharing of chores, stunning scenery and immersion in various cultures make for a valuable and inspiring venture.
And he's eager to have students experience it as well. Last summer, then-graduate students Leeuw and Alison Chase participated in the 2013 Tara Oceans Polar Circle expedition, as did the husband-and-wife Boss pair — Emmanuel and Lee Karp-Boss, associate professor in UMaine's School of Marine Sciences.
They utilized a $149,714 grant from NASA to gather biogeochemical information from the Arctic Ocean — information that NASA uses to verify data that its satellites glean daily from the same water.
This summer, Boss and Leeuw, who this spring earned his master's degree in oceanography, will utilize an additional NASA award of $27,000 to continue collecting data in the Mediterranean.
Boss says he was persistent in his efforts to get NASA to provide the follow-up funding. “If you want to make something happen, put all of your weight and belief behind it to make it happen,” he says. “You only live once; go for it. Don't give up on your dream.”
He gives similar advice to students.
Leeuw says his interest in oceanography emerged when he took an undergraduate course with Boss. Leeuw, a marine science major, subsequently became a research assistant in the University of Maine In-situ Sound and Color Lab.
Multiple opportunities subsequently became available, he says. Leeuw and Boss analyzed data collected from 2009 to 2012 during the Tara Oceans expedition. This past year, the two developed an iPhone app that measures water quality.
And after this summer's month-long Mediterranean trek, the Lincoln, Vermont, native will drive cross country to Washington state, where he has accepted a job developing environmental sensors at Sequoia Scientific, Inc.
The lesson: “Don't be afraid to make friends with faculty; some of the best learning and research opportunities can happen outside the classroom,” Leeuw says.
Last summer's Arctic trip was unlike anything Leeuw had ever experienced. “It was empowering to work as a scientist,” he says. “It prepared me for this upcoming situation. I'm more confident.”
He monitored a suite of optical instruments and as water was pumped into the vessel's flow-through system, he recorded its temperature, salinity profile and fluorescence.
Leeuw calls the data that UMaine collected last summer — which is free and accessible to the public — unparalleled. “We drifted up to an ice pack and took a bunch of samples,” he says. “The water was below freezing but there were massive plankton blooms. Just amazing."
A UMaine student is currently working to identify the types of species, he says.
During that trek, Tara was blocked by ice in the Vilkitsky Strait for about a week. When Tara was able to forge ahead, she arrived late at the next destination — Pevek, Russia. The scientists departing the vessel after that leg of the trek, including Leeuw, had missed that week's one flight out of the northern port.
This summer's adventure begins for Leeuw on June 26, a couple of weeks after World Oceans Day. He'll board Tara in Nice, France, work for just over a month and debark in Cyclades — a dazzling Greek island group in the Aegean Sea.
Results of the voyage are expected to provide scientific insight into “what is in the ocean — where species are and why they are there,” Leeuw says, all of which advance researchers' understanding of the ocean and the mission of Tara Expeditions.
Etienne Bourgois, president of Tara Foundation, says Tara's quest is to understand what is happening with the climate and to explain it simply.
“This exceptional ship must pursue her mission as ambassador of the world's citizens, must remain a catalyser of energy and desire to tackle without glitter the main question that arises for each one of us: What future are we preparing for our children?” he says on the website.
