Watershed Kiosks

In 2006, staff at the NOAA National Marine Fisheries Service Maine Field Office initiated a partnership with Maine Sea Grant to produce content for two informational kiosks planned for the lower Penobscot River region. The Penobscot River watershed is currently the subject of an unprecedented restoration plan that will restore access to over 1,000 miles of rearing and spawning habitat for Atlantic salmon, alewives, sturgeon, and other species of sea-run fish.

Estuarine and coastal sediments release dissolved organic carbon (DOC) due to the high level of organic matter decay brought about by microbial activity, particularly sulfate reduction. High levels of DOC can lead to mobilization of toxic metals and chemicals. DOC flux may be affected by an increase in microbial activity due to rising temperatures and changing hydrology as a result of climate change.
