  • Research Interests and Activities:
    William H. McDowell has worked at the Hubbard Brook Experimental Forest since 1977. His research interests include the biogeochemistry of streams and forests; he is particularly interested in dissolved organic carbon and nitrogen. His most recent work at Hubbard Brook includes a study of N dynamics in Bear Brook the stable isotopic tracer 15N. He is also involved in work on the nitrogen cycle at the Cone Pond watershed with other HBES investigators.
