Clear Seas is celebrating a milestone: five years of providing research on issues around sustainable marine shipping – from underwater noise, oil tankers, air pollution from ships and more – to over 200,000 website users, most of whom are in Canada. During its first five years, Clear Seas has become key to building awareness about commercial marine shipping and to reach Canadians of all ages and backgrounds, from policy makers, researchers, and educators, and anyone who wants to learn more about marine shipping issues. The organization is now looking forward to the value it will bring in the years to come.
