Modeling a Large Coastal Upwelling Event in Lake Superior

Spatial distributions of zooplankton during coastal upwelling in western Lake Superior

Zooplankton distributions during coastal upwelling in western Lake Superior were mapped with a high-frequency (192~kHz) sonar system that consists of an echosounder and a navigation receiver connected to a microcomputer. An acoustic transect after a September storm revealed a sloping sound-scattering layer, traceable more than 5 km offshore, in the thermocline between an upwelling water mass an...

Modeling nearshore-offshore exchange in Lake Superior

Lake Superior's ecosystem includes distinct nearshore and offshore food webs linked by hydrodynamic processes that transport water and tracers along and across shore. The scales over which these processes occur and their sensitivity to increasing summer surface temperatures are not well understood. This study investigated horizontal mixing between nearshore and offshore areas of Lake Superior o...

Coastal upwelling in a warmer future

[1] Coastal upwelling helps set the physical context for marine ecosystems, and upwelling zones are among the most productive regions of the global ocean. Unlike earlier models, two state-of-the-art climate models exhibit little change during the next century in the magnitude and seasonality of coastal upwelling, but climate models are still probably not sufficiently developed (for example, the...
