Background and General Description of Lesson
Somes Sound is the only natural fjord on the East coast. It is a deep, narrow inlet of the sea carved into Mount Desert Island by a glacier. A ridge of material at the mouth of the sound restricts the free exchange of ocean and estuary water, creating a semi-closed system.
During this lesson, students collect chemical, physical and biological data within Somes Sound. The goal is to assess the fjord’s ecological health and ability to sustain life. Traveling by boat, students and instructors run tests at 3-4 different areas in the Sound and interpret the data collected.
