Sens. Olympia Snowe and Susan Collins of Maine say federal grants totaling more than $1 million are being awarded to the Bigelow Laboratory for Ocean Sciences. They say a grant of nearly $1 million will go toward construction of a new facility focusing on ocean acidification. A second grant of about $150,000 will help fund a study of the ecosystem within the earth’s crust underneath the ocean floor. From its base in Boothbay Harbor, Bigelow scientists have traveled around the world to every ocean and the polar seas. Research ranges from microbial oceanography to large-scale interactions between ocean ecosystems and global environmental conditions.
