A light station was established on Maine’s 220-acre Great Duck Island in 1890, with a 42-foot-tall brick tower and three keepers’ dwellings. Only one of the three houses remain standing today. The light was automated in 1986 and it remains an active aid to navigation. In 1998 Great Duck Island Light Station, along with Mount Desert Rock Light Station, became the property of Bar Harbor’s College of the Atlantic. Students and staff from the college now live in the former keeper’s dwelling much of the year. The ongoing research projects largely focus on the island’s bird populations.

John Anderson has been a professor at College of the Atlantic for more than 30 years. His field research centers around Great Duck Island. John says that he is interested in the intersection between natural history and human history in relation to long-term ecological processes.
