Because WHOI operates year-round, its needs do not necessarily increase in the summer months. If interested in a job, please browse WHOI's list of current job openings [2]. If you are interested in a summer position, you should monitor this page regularly to see if a job has been posted, and follow the same procedures as you would for all of our job openings.
