Salt-marsh foraminiferal species live in distinct elevation zones relative to tidal and sea-level datums. The vertical zonation of foraminifera can be used as a tool in reconstructing rates of sea-level rise and quantifying both uplift and subsidence along coastlines. Although foraminifera have been used across the globe to reconstruct past sea levels, no such elevation zonations have been documented for southern California salt-marsh foraminifera. This knowledge gap impedes both the production of reliable sea-level curves to better understand climate change, as well as the refinement of southern California’s tectonic history. Therefore, understanding the modern distribution of foraminifera may provide estimates of uplift and or subsidence associated with the Santa Barbara LTER study site.
