Mark Wells

Mark Wells, Ph.D., is a Professor in the School of Marine Sciences at the University of Maine. His research focuses on marine dissolved organic matter (DOM), particularly chromophoric dissolved organic matter (CDOM) and colloids, with an emphasis on their impact on light propagation, remote sensing, and biogeochemical cycling. He investigates CDOM's variability in surface and deep waters, its interaction with biological processes, and photochemical degradation effects on its composition and residence time. His work integrates experimental oceanography, analytical chemistry, and field studies.

Education: Ph.D. in Marine Sciences from the University of Maine. His expertise spans trace metal biogeochemistry, harmful algal blooms, and phytoplankton ecology. Key methodologies include continuous culture systems, quantum dot applications, and novel iron sequestration technologies.

Research trends in his publications emphasize CDOM colloids, iron cycling, and the interplay between metals and phytoplankton physiology. Findings highlight the role of colloids in mediating DOM optical properties and the importance of trace metals like iron and copper in regulating marine productivity and toxin production. His work contributes to understanding oceanic responses to environmental changes and remote sensing data interpretation challenges.

Advising and grants: While specific student names are not listed, his research likely involves graduate students and postdoctoral researchers. Funding sources are inferred from collaborative projects involving oceanographic institutions and federal agencies. Active teams include interdisciplinary groups studying marine biogeochemistry and coastal ecosystems.

Labs/Teams: Part of the University of Maine’s marine sciences research community, contributing to initiatives in coastal oceanography, harmful algal bloom monitoring, and trace metal analysis. Collaborates with institutions such as NOAA, NASA, and international oceanographic programs.
