Earthwatch recruits participants and prepares them to assist researchers in the field. Earthwatch participants can be adults, students (age 15-18), teachers, or corporate employees.
Participants join researchers in the field for set blocks of time in groups called teams. A typical project would require engagement of a minimum of 4 and up to 15 participants per team on 4 to 10 teams per year. Each team typically spends 7-17 days in the field.
Students are a key participant group for Earthwatch; it is advantageous to be open to student participants (age 15-18). It is also advantageous to be open to occasional larger groups of participants.
