Scientist have traditionally been limited in their measurement capabilities to what's local and current. With computational modeling, we are capable of using those point measurements to scale up to global biogeochemical cycling, to unearth cycling from the past, and to project future cycling. We use a combination of rate and isotopic measurements to inform our models; to look at how the earth functioned prior to human industrialization and how it will function moving forward, as we continue to alter biogeochemical cycling.
