The ocean is under assault on a number of fronts. Two of the most egregious are excessive nitrogen that feeds harmful algal blooms to create ocean dead zones, and excessive carbon dioxide (climate change) that is making the waters more acidic. To save the ocean we need to better understand it, become more ocean literate. We must also be respectful of the awesome amount we do not know. Discover what you can do in your backyard and out into communities to save the ocean. Dr. Moir will illustrate his talk with images from last summer’s sail from Iceland across the Denmark Strait to Nuuk, Greenland.
