Zachary C. Johnson

Research Hydrologist for the Washington Water Science Center

My research interests are at the intersection of watershed hydrology, ecology, biogeochemistry, water and land management, and fluvial geomorphology using field measurements, remote sensing, laboratory, and modeling techniques. I am particularly passionate about topics such as surface-subsurface exchanges, terrestrial-aquatic linkages, anthropogenic interactions, statistical and deterministic modeling, and the importance of spatial and temporal scale for watershed processes.

Transdisciplinary science: A path to understanding the interactions among ocean acidification, ecosystems, and society Transdisciplinary science: A path to understanding the interactions among ocean acidification, ecosystems, and society

The global nature of ocean acidification (OA) transcends habitats, ecosystems, regions, and science disciplines. The scientific community recognizes that the biggest challenge in improving understanding of how changing OA conditions affect ecosystems, and associated consequences for human society, requires integration of experimental, observational, and modeling approaches from many...
