York 7 is in the middle of an expedition called Warming Waters which partially consists of students testing and comparing results of water samples to see what effects, if any, global warming is having, will have, or has had, on the quality of the water. Students have been testing water at Mackworth Island, Maine Yacht Center, and East End Beach, for dissolved oxygen (DO), potential hydrogen (PH), and salinity. Kids can be seen writing results and observations, testing, and collecting samples of the water at the fieldwork sites in the pictures that are soon to come to the blog.
