We are very excited to announce the team for the 2018 Polaris Project expedition to the Yukon-Kuskokwim Delta. We are 21 people strong, including 12 students (10 new undergraduates and 2 from the 2017 team who are returning for another round) who were selected from a remarkably strong set of applicants. The students come from across the US and from a great diversity of backgrounds. We look forward to our first online meeting in early March and to assembling the team in Woods Hole April 7-8 for safety training and orientation. Our expedition to the Yukon River Delta in Alaska will launch in late June. A complete list of the 2018 Polaris Project participants can be found here.
