project study area covers the United States Great Lakes coastal margins
from Grand Portage, Minnesota, to Watertown, New York. Samples are collected
primarily along the coastal margin, but sampling may occur inland up
to 1 kilometer (about 2/3 mile) for birds; fish, invertebrates, diatoms,
and water quality data are also collected in waters 10 to 30 meters
(30- 100 feet) deep.
