Research Projects

Juhl Lab research outputs can be grouped into several categories:

How do aquatic microorganisms and their predators interact with each other and the physical/chemical environment to control fluxes of major elements such as carbon, nitrogen, and phosphorus?

What combination of physical, chemical and ecological factors come together to allow certain groups of algae to dominate the phytoplankton, forming blooms that can harm human, animal, and ecosystem health?

What factors control the growth of algae inside of sea ice? How is the community of organisms inside sea ice connected to other arctic marine organisms? What is the fate of organic matter that builds up inside sea ice?

Documenting the sources, fate and consequences of aquatic pollutants such as sewage microbes, excess nutrients, pharmaceuticals, oil, and other contaminants.
