| CU Maurice River is once again participating in a nationwide study of mercury deposition that is coordinated by the University of Maine\, National Park Service\, and the US \; Geological Survey. The Dragonfly Mercury Project \;is conducted in national parks across the continental United States and is now the country'\;s largest mercury contamination assessment. This year marks the study'\;s 10th anniversary. \n \; \n In the United States\, the primary anthropogenic source of mercury emissions into the atmosphere stems from the burning of coal and mining activities. Mercury is dispersed via wind currents and other natural forces. It is then deposited in parks\, rivers\, and other natural areas through precipitation. In certain environmental conditions\, like those found in aquatic habitats\, it is converted by microorganisms into methylmercury - a neurotoxin. In this form\, this contaminant bioaccumulates as it moves through the food web. Exposure to and consumption of methylmercury can cause the health of ecosystems\, wildlife\, and humans to deteriorate\, so it'\;s important to know the levels in our environment. \n \; \n Dragonfly larvae can live up to six years in the water before emerging. They are high on the aquatic food chain which makes them an indicator species of habitat health. In addition\, dragonfly larvae are easy to catch and analyze\, making them a prime candidate for scientific studies. The collection of dragonfly larvae gathered through this project offers data that will help scientists better understand the extent of mercury contamination and deposition trends in the United States. \; \n \; \n Over three days\, August 1-3\, volunteer community scientists will sample three sites within the Wild and Scenic Maurice River Watershed. Precise sampling locations will be shared before this effort. Community scientists will meet at the CU Maurice River office for a short introductory presentation on the Dragonfly Mercury Sampling project before carpooling to our testing sites. \n \n Be prepared to volunteer for this event. \; Quick-dry synthetic clothing and water shoes (not sandals) need to be worn\; expect to get wet. \; Wading in the water up to your knees\, or higher\, is likely. \; There are also important jobs for a few community scientists who might feel more comfortable on land. \; Life jackets will be required at all times while in the water. \; Inspect repellent and sunscreen are highlight recommended for this outing as well as an ample amount of drinking water. \n \n CU Maurice River has a limited number of life jackets for participants to borrow so if you have your own\, please bring it with you. \n \n Registration is required for this event. \; Sign up at \;lp.constantcontactpages.com/ev/reg/vxjdx2k?source_id=ccd4f947-38ee-40b3-be61-f7d394234591&\;source_type=em&\;c=R-fZn4357Jl1Y3KJ2RwEekVi3UPgYWTGgiZwsAwEVSJujZoddacwkg== | \n
