Cantrell and Fain's underwater stay lasted 73 days, two hours and 34 minutes, breaking the world record for longest time spent living underwater.

"There is a sun," Cantrell said with a laugh as he and Fain broke the surface of the water.

"Going in, we had goals that we wanted to accomplish," Cantrell said. "At the end of 73 days, I think we've exceeded those goals. We've reached a lot of people. Now the challenge for us is to carry that forward."

Fain said that teaching people about ocean conservation was one of the project's most important goals.

"I really hope that people take away from this that the oceans are something that we need to protect," Fain said. "We need to learn more about the oceans and how they work."

Their mission broke the record held by Richard Presley (69 days, 19 minutes in Jules' Undersea Lodge from May 6-July 14, 1992). Presley greeted Fain and Cantrell after they surfaced.

"It's exciting to see the focus more on education and using technology to involve more students," Presley said. "We didn't have that technology in '92."

While living 25 feet underwater, Fain and Cantrell hosted nine episodes of an online lecture series titled Classroom Under the Sea. Presented by Roane State and the Marine Resources Development Foundation, Classroom Under the Sea featured guests such as astronaut Buzz Aldrin and marine life artist Wyland.

Viewers have watched 65,000 minutes of Classroom Under the Sea video content on the project's YouTube channel. Video content has been viewed in 124 countries.

Cantrell and Fain also spoke by video chat with students across the country and around the world. Students at a small school in Nickelsville, Va. shared their thoughts on talking with two professors living underwater.

"Our school is a very small school; we don't even have 300 people," wrote senior Chelsey Stapleton. "So getting this chance to talk to Bruce and Jessica about their experience was so interesting and amazing."

Marine Resources Development Foundation and Jules' Under the Sea Lodge arranged for middle school students and high school students to have "Lunch with the Aquanauts." Thirty students participated, including groups from Massachusetts, Maryland and North Carolina.

Cantrell and Fain also received dozens of letters from students.

"When you start hearing back from these students, and they're telling you 'this is so cool' and 'what's it like living underwater,' you really feel like you are reaching your goals," Fain said. "You feel like you are making a big difference in their lives. We brought a whole new world to some of these kids."

In addition to hosting shows and speaking with students, Cantrell taught a college-credit course - BIOL 2600: Living and Working Under the Sea - for Roane State students.

Fain made her own mark by breaking the record for a female living underwater. The record was 14 days, set in 1970 by scientist Dr. Sylvia Earle and her team during their stay in the Tektite habitat. The Tektite program was the first nationally sponsored effort to place scientists in the sea to live.

"It's a great honor," Fain said. "She's a pioneer. She's a great marine biologist. By me living underwater for 73 days, I'm making a big step for females and showing girls, especially young girls, that it's OK, that this may be a field where there's a lot more guys, but girls can definitely succeed."

In 1986, the habitat started a new life as Jules' Undersea Lodge, which is the only underwater hotel in the world and accessible to any recreational diver. Learn more at www.jul.com.

They entered the habitat on Oct. 3.

On Monday, Nov. 3, Fain and Cantrell had lived underwater for 31 days, surpassing the 30-day mark set by famed explorer Jacques-Yves Cousteau's oceanauts in Conshelf II (1963) and by astronaut Scott Carpenter in SEALAB II (1965).

Conshelf II was a project, led by Cousteau, to create an ocean-floor habitat for humans. The U.S. Navy's SEALAB program was an effort in the 1960s to experiment with underwater habitats.

On Tuesday, Nov. 4, Fain and Cantrell's 32 days underwater surpassed the 31-day mark recorded this summer by Fabien Cousteau, Jacques Cousteau's grandson, in the underwater habitat Aquarius.

"Jessica and I are proud and humbled to add our modest contributions to the great work of Jacques Cousteau, Scott Carpenter and Fabien Cousteau," Cantrell said. "They inspired us, and we share their vision to teach others the wonder of the oceans and the importance of conserving our environment."

Fain and Cantrell plan to resurface Dec. 15 after 73 days underwater. The current overall record for living underwater (69 days, 19 minutes) was set by Richard Presley in 1992, according to Guinness World Records.

On Oct. 18, Fain also set the record for a female living underwater. The previous mark was 14 days, set in 1970 by renowned scientist Dr. Sylvia Earle and her team during their stay in the Tektite habitat. The Tektite program was the first nationally sponsored effort to place scientists in the sea to live.

As of Saturday, Oct. 18, Fain and Cantrell had lived continuously underwater for 15 days.

"I am honored to be among a select group of aquanauts that includes people such as Sylvia Earle," Fain said. "It is a surreal feeling to know that I am one of very few women who have lived in an underwater habitat for an extended period of time. To know that I am now the only female to live in an underwater habitat for this long is an incredible personal achievement and I hope it inspires future generations of women."

The current overall record for living underwater (69 days, 19 minutes) was set by Richard Presley in 1992, according to Guinness World Records. Fain and Cantrell submerged on Oct. 3 and plan to resurface Dec. 15.

Jules' Undersea Lodge was the undersea research habitat called "La Chalupa," which Marine Resources Development Foundation operated from 1971-1976. Several missions were conducted in the habitat, including two at a depth of 100 feet. In 1986, the habitat started a new life as Jules' Undersea Lodge, which is the only underwater hotel in the world and accessible to any recreational diver. Learn more at www.jul.com.

"We're excited, after months of planning, to begin our mission to raise awareness about marine science and ocean conservation and to encourage young students to pursue science fields," Cantrell said. "We have a fantastic lineup of topics and guest speakers for the lecture series, and we deeply appreciate the Marine Resources Development Foundation, Jules' Undersea Lodge and our sponsors for giving us this once-in-a-lifetime education opportunity."

Jules' Undersea Lodge is located 25 feet down in the lagoon at the Marine Resources Development Foundation on Key Largo in the Florida Keys.

While in the habitat, where living space is the size of a dorm room, Fain and Cantrell will host weekly live episodes of the online lecture series Classroom Under the Sea, presented by Roane State and the Marine Resources Development Foundation (MRDF).

The first episode, "History of Man in the Sea," will be Thursday, Oct. 9 at 1 p.m. EDT. Cantrell and Fain will host episodes each Thursday at 1 p.m. Eastern through Dec. 11, with a one-week break for Thanksgiving.

"Marine Resources is an advocate for conservation," said Ginette Hughes, senior vice president for MRDF. "We hope Classroom Under the Sea will show that the health of our oceans affects all communities, whether they are located near the coast or hundreds of miles away."

Fain developed laboratory lesson plans that relate to the topic of each episode. Teachers and parents can download lesson plans and conduct experiments with students. The lesson plans are available at roanestate.edu/classroomunderthesea.

"Part of our mission is to excite students about science," Fain said. "One of the best ways to develop a student's interest in biology, chemistry and other subjects is through hands-on activities. The lessons plans are a great way to let students see that science is more than just what is in a textbook."

Classroom Under the Sea topics include "The Sea and Space Connection," on Oct. 16, which will feature astronaut Buzz Aldrin; "Marine Archaeology" on Nov. 6, which will discuss how scientists find and restore cultural resources lost in the oceans; and "Coral Restoration," on Dec. 4, which will address the devastation of coral reefs.

Roane State adjunct professor Jessica Fain wants to do her part, and she's willing to live underwater for 72 days to show that science is cool, for boys and for girls.

"I definitely see those social barriers for girls interested in science," Fain said. "They don't want to be labeled as the nerd. We still have this stigma of wanting to be the popular girl and not wanting to be the science geek. I want them to see that it is OK to be the smart, nerdy girl."

Fain, who has a bachelor's degree in biology and teaches biology labs for Roane State, will participate in Classroom Under the Sea, a joint project between Roane State and the Marine Resources Development Foundation in Key Largo, Fla. Along with Roane State biology professor Bruce Cantrell, Fain will live and work in an underwater habitat for 72 days this fall (Oct. 4-Dec. 15).

The habitat, Jules' Undersea Lodge, is located 25 feet below the sea in the lagoon at the Marine Resources Development Foundation. While they live in the habitat, Fain and Cantrell will host a weekly program titled "Classroom Under the Sea" that will cover a variety of topics in marine science.

Classroom Under the Sea is the type of hands-on science experience that fascinates students, Fain said. Lab experiments inspired Fain to pursue science, and she hopes living underwater shows students that science is more than reading textbooks.

"Hands-on experiences are the best way to get young people interested in science," Fain said. "Why not do the fun, exciting experiences when they are impressionable? That excitement will carry over into other, harder concepts.

"I could read about air pressure all day long, but when I am in a lab and can physically see the way air pressure affects things, I am getting the concept. I can read about the ocean ecosystems. I can read about how they use the wetlands and inland lagoon areas as nurseries, but with Classroom Under the Sea, I can actually see it and help show young people what is happening."

Fain, of Lenoir City, graduated from East Tennessee State University in 2011 and began teaching for Roane State.  She is an experienced diver who has logged more than 100 hours in underwater habitats and labs.

The natural world, Fain said, has fascinated her since childhood. She said she "fell in love with marine science" the first time she went snorkeling.

"It's amazing how many systems go into an ecosystem underwater," she said. "Nature has this cool way of if something happens to that balance, it can rebalance itself. I'm passionate about marine science and preserving our oceans, and I hope that people who watch us during Classroom Under the Sea will see that if you are passionate about something, and you go out and do it, most likely you are going to open doors for yourself."

Classroom Under the Sea programs will be available for anyone to watch at roanestate.edu/classroomunderthesea and on youtube.com/classroomunderthesea. Sponsors of Classroom Under the Sea include Diversity in Aquatics and the Professional Association of Diving Instructors (PADI).

This fall, Cantrell will finally have a chance to teach Roane State students about living and working under the sea. And he'll do it while he actually lives and works under the sea.

Cantrell and faculty member Jessica Fain will live and teach from an underwater habitat for 73 days this fall. While they live in a space the size of a college dorm room submerged about 25 feet, Cantrell and Fain will host weekly shows titled Classroom Under the Sea.

The shows, presented in partnership with the Marine Resources Development Foundation on Key Largo in the Florida Keys, will feature scientists and explorers and will cover topics such as underwater archeology and ocean exploration.

In addition to the weekly programs, Cantrell will also teach his dream class online, BIOL 2600: Living and Working Under the Sea. Enrolled Roane State students can register for the class now, but only 30 spots are available.

Students in the class will be able to interact live with Cantrell and Fain through video conferencing.

"What we're going to do, staying 73 days, has never been done before," Cantrell said. "Teaching an online, college-level course from an underwater habitat has never been done before. I'm excited to share this experience with Roane State students and to engage them in learning about marine science. I can't wait, and I hope students will be excited that while they chat with me online, I'll be 25 feet underwater living in the environment they are studying."

Cantrell and Fain will start their underwater adventure Oct. 3 and resurface on Dec. 15. They will live in Jules' Undersea Lodge, which is in the lagoon at the Marine Resources Development Foundation's facilities on Key Largo in the Florida Keys. The weekly programs will be available for anyone to watch at roanestate.edu/classroomunderthesea and on youtube.com/classroomunderthesea.

During their stay, Cantrell and Fain will set a world record for the longest time spent living underwater. What excites Cantrell and Fain most, though, is the opportunity to show young students the value of education in science.

"The coolness factor is definitely there," Fain said. "But I think there is a great need for education for our middle schoolers especially in science or marine biology. To be able to reach people in this kind of manner is something that hasn't been done, and I think that's going to be very exciting. If maybe even a fourth of students who watch us, or not even students just people, if even a fourth of them become interested in science, interested in conserving our marine ecosystems, then to me it's been a success."

Roane State has a long relationship with the Marine Resources Development Foundation. Since 2005, Cantrell has taken about 20 students a year to participate in the foundation's MarineLab education program.

Roane State fall classes begin Aug. 25.

While underwater, associate professor of biology Bruce Cantrell and adjunct instructor Jessica Fain will offer the most unique educational experience in the college's history and raise awareness of issues affecting the oceans. During their stay, Cantrell and Fain will also set a world record for the longest time spent living underwater.

Roane State and the Marine Resources Development Foundation on Key Largo in the Florida Keys, are partnering on the Classroom Under the Sea project. Cantrell and Fain plan to start their underwater adventure Oct. 3 and resurface on Dec. 15. They will live in Jules' Undersea Lodge at the Marine Resources Development Foundation's facilities.

"Roane State professors have taught in a variety of locations as part of our mission to bring higher education to the communities we serve," Roane State President Dr. Chris Whaley said. "What Bruce and Jessica are planning is certainly new territory. While their project is unique, their expertise, spirit of adventure and passion for teaching are representative of what make community colleges so special."

Roane State has a long relationship with the Marine Resources Development Foundation. Since 2005, Cantrell has taken about 20 students a year to participate in the foundation's MarineLab education program. While at MarineLab, Roane State students survey coral reefs and upload their findings to a database hosted by the Los Angeles-based Reef Check Foundation.

The Marine Resources Development Foundation is led by Ian Koblick, president, chairman of the foundation's board and the organization's founder. Koblick, an expert in underwater habitats, designed the sophisticated undersea lab La Chalupa, which he and partner Dr. Neil Monney later converted to Jules' Undersea Lodge. The lodge is located in the lagoon at the Marine Resources Development Foundation's facilities. Jules' Undersea Lodge is about 600 square feet, with approximately half for living space.

Koblick approached Cantrell last fall about the Classroom Under the Sea project, and Cantrell accepted the offer to participate. Cantrell invited Fain, who has assisted with organizing Roane State trips to MarineLab.

"Each year, I have been deeply impressed by Bruce and the Roane State students who visit MarineLab," Koblick said. "When we came up with the idea for Classroom Under the Sea, I knew I wanted to involve Bruce and Roane State."

While underwater, Cantrell and Fain will host a weekly program featuring interviews with leading scientists and explorers. Plans are for the programs to be hosted on the Roane State website. A schedule and further details will be announced at a later time.

Roane State students in Cantrell's fall online biology class will have an especially interesting experience. While they take Cantrell's course, he will be leading it from Jules' Undersea Lodge.

"I developed my passion for marine science while in the Navy and have continued to study it throughout my career," said Cantrell, a Roane County native and Harriman High School graduate. "I am honored to have the opportunity to raise awareness about issues affecting our oceans, promote the value of underwater habitats and to offer an amazing learning experience for my students."

Cantrell started teaching at Roane State in 1992. A veteran of the U.S. Navy and U.S. Army, he has an associate degree from Roane State, a bachelor's degree in biology from Tennessee Tech and a master's in biology from American University. Cantrell has numerous diving certifications, and he has logged more than 200 hours in the Jules' underwater habitat, including four 24-hour stays.

Fain, of Lenoir City, graduated from East Tennessee State University in 2011 with a bachelor's degree in biology and became an adjunct instructor at Roane State. While at Roane State, she became a certified scuba diver and has since earned additional diving certifications. She has logged more than 100 hours in underwater habitats and labs and accompanied Roane State students to MarineLab for the past three years.

"I have a particular interest in introducing students to coral reef ecology and to helping them understand the need to protect the ecological balance of both freshwater and marine ecosystems," Fain said. "The Classroom Under the Sea project is a once-in-a-lifetime teaching opportunity, and I'm looking forward to it."

Jules' Undersea Lodge (named for writer Jules Verne), where Cantrell and Fain will stay, is located 25 feet below the surface of the sea the Marine Resources Development Foundation's facilities. For safety, Jules' Undersea Lodge is monitored at all times by Jules' staff.

While they can leave the lodge for underwater excursions, Cantrell and Fain do not plan to break the surface of the water for 73 days. If successful, they will break the record of Richard Presley, who spent 69 days and 19 minutes underwater from May 6-July 14, 1992, according to Guinness World Records.
