Marine Science students set out on Casco Bay on the College’s boat, SeaWolf, to collect samples. Contributed SOUTH PORTLAND — Southern Maine Community College students are taking a look at the cause of red ties in Casco Bay, thanks to a new federal grant.According to the Maine Department of Marine Resources, the state each year see red tides, a bloom in harmful algae that occurs in the Gulf of Maine. Shellfish, which are filter-feeders, consume these harmful toxins and become unsafe for human consumption. “We will be using it to look at red tide organisms, there are two in particular that can produce toxins that can make shellfish unmarketable,” marine science instructor Brian Tarbox said. “There is also a third species not seen in Maine until three years ago – it’s not known to be a human hazard but can deplete oxygen in the ocean.” In their research, students are hoping to find diatoms, or micro algae, to see if they produce neurotoxic chemicals. By confirming its presence, they may be able to better predict harmful algal blooms in the future, according to marine science major Allyson Fogg. “It is important to determine if it is present because harmful blooms… Read full this story
