Short summary

Due to climate change shifts in ecosystem structure and function have been increasingly documented in marine ecosystems around the globe. We tested whether a marine biogeochemical model can predict shifts to alternative regimes in plankton and biogeochemical processes under environmental perturbations. Simulations show that perturbations can drive the system into new regimes, with responses that are either reversible or hysteretic, depending on the type and intensity of the disturbance.
