Beverly J. Johnson

Professor of Earth and Climate Sciences


Earth and Climate Sciences

Carnegie Science Hall, Room 409


Bev Johnson’s  research interests involve using geochemical analyses to explore environmental change over a range of temporal and spatial scales.  She specializes in organic and stable isotope geochemistry, and the use of stable carbon, nitrogen and sulfur isotopes in modern and ancient organic matter.  Bev and students investigate topics such as (1) the carbon dynamics and history of Maine salt marshes, (2) changes in diets of ancient fish and humans along the coast of Maine, (3) nutrient transfer from anadromous fish into coastal fresh water lakes, and (4) the use of archival datasets to reconstruct long-term changes in water quality on the Androscoggin River.

Bev is a member of the international scientific working group on coastal blue carbon, and studies the potential of carbon storage and sequestration in salt marshes as a means for mitigating climate change.  Bev is a member of the Coastal and Marine Working Group of the Maine Climate Council, and is a founding member of the Maine blue carbon network.

Bev teaches first year seminars titled Coastal Hazards (FYS  476) or Burning Our Planet (FYS 284), an introductory course on Global Change (EACS 109), intermediate courses in Environmental Geochemistry (EACS 240) and Hydrogeology (ESEA 226), advanced courses in Biogeochemistry and Paleoclimatology (EACS 367) and Stable Isotopes and Past Environments (EACS 340).  Occasionally, Coastal Hazards or Hydrogeology are taught as short term units.  Bev often integrates student research projects into her classes.  Students investigate various aspects of the Androscoggin River at all levels of the curriculum, for example.
