As a result, applications are invited for projects making a significant contribution to current environmental debates and with a potential to influence a wider public. Applicants with an interest in post-graduate training in practical marine science will also be welcome.

The prize on offer is five days aboard Prince Madog during next year for a proposed science or training project for which the winner will be awarded a certificate before being invited to present a lecture at a future Challenger Society event.

A science prize, peer-reviewed by NERC, will be awarded on the basis of scientific merit and originality while that for training will be dependent upon proposed training outcomes and a potential to satisfy future requirements of scientists at sea.

Applicants must provide a letter of nomination, a nominee's CV and a two-page science case or outline training plan. The closing date for submissions is 17 December, with the winner being announced next February.
