From the website, www.semesteratsea.org:

• “Semester at Sea voyages offer a truly global experience each fall and spring. All … voyages on the MV World Odyssey are 100+ days, explore at least 10 countries and 4 continents, and allow students to earn 12-15 academic credits from Colorado State University“
• “… students select academic courses drawn from 20 – 25 fields of study that are integrated with relevant field classes in up to a dozen countries, allowing for an experiential, comparative education that is truly global”
• “The Institute for Shipboard Education (ISE) is a 501c3 nonprofit based in Fort Collins, Colorado that administers the Semester at Sea study abroad program in conjunction with the Colorado State University … Since 1963, more than 68,000 individuals from 1,700 institutions, have traveled to more than 60 countries on Semester at Sea and its predecessor programs”.

As it looks, in the summer half of the year, the ship is used as a cruiser named “Deutschland”, while, in the winter half of the year, it serves as the floating campus of “Semester at Sea” / Soweit erkennbar, fährt das Schiff nun im Sommerhalbjahr als Kreuzfahrtschiff „Deutschland“ und im Winterhalbjahr unter dem Namen „World Odyssey“ als Campus für „Semester at Sea“.
