What do a rum company and green-oriented environmentalists have in common? They're both teaming up to offer a short an unusual internship. Click here to learn more about green internships.

Malibu Rum has teamed up with Reef Check to offer 10 people a Malibu beach internship working as coral reef health checkers. The interns who are selected will travel to Thailand, the Maldives or the Philippines to work with Reef Check, a group that monitors, protects and rehabilitates coral reefs.

The internships, which last 10 days, are unpaid. But the program is an innovative way to encourage interns to try something different, instead of sitting in an office all day during the summer.

On top of that, it's a win-win for both companies. Malibu gets to promote its rum, while Reef Check gets to highlight the importance of coral reef health which can be an important early indicator in the effects of global warming.

Applicants must be U.S. citizens and at least 21-years old. Those who convey the most creativity, enthusiasm and character will be selected as finalists. Those interns will then blog about their experiences.

"What we love about the Malibu/Reef Check Partnership is that it is very real - with on-the-ground training in reef monitoring - the core of the Reef Check program," Dr. Gregor Hodgson, founder and executive director of Reef Check, said. "With Malibu's help we can reach out to so many thousands of young people and engage them in marine conservation."

Anyone not selected to be a Malibu beach intern can still join Reef Check expeditions to destinations such as the Philippines, Oman and Honduras, with fees ranging from around $999-$3000 for the dive trips.
