MIT Sea Grant College Program Brown Bag SeminarTuesday April, 26thE38-3rd Floor Conference Room12:00 ¤ 1:00pmFor the past two decades, efforts to stem the tide of new marine invasions focused on ballast water exchange and treatment. Nonetheless, established invasive species populations are expanding their ranges and the rate of introduction is likely to increase. The role of hull fouling in spreading marine species has been underestimated, but climate-related impacts, such as increased sea temperatures, ocean acidification, changes in salinity and habitat alterations also contribute to expanding ranges and new introductions. This talk reviews changes observed in local populations and challenges the engineering community to develop innovative approaches to antifouling coatings.We encourage attendees to bring their lunch to the seminar. The seminar is open to the public. Please pass this announcement along to interested parties. Questions can be sent to KBaltes@mit.edu.
