Ecosystem calculations such as NPP are often complex and commonly not replicated. In some cases, methods for estimating confidence in ecosystem pools and fluxes are lacking.

Kelps are highly productive, yet little is known about the fates of kelp primary production. Traditionally, kelps have been assumed to form the base of kelp forest food webs.

Frontal regions are common in the California Current Ecoystem (CCE) and are often sites of increased upwelling, downwelling, and biological production. Therefore, they likely play an importan
