Planktonic foraminiferal area normalized shell weight data and model carbonate system simulations for the 20th century California Current ecosystem

These data are based on the planktonic foraminifera species G. bulloides' shell characteristics, specifically area-normalized shell weight (ANSW) and include both core sample population average values and the individual data used to calculate sample averages.

Additional information on collection of ANSW data can be obtained in Osborne et al., (2016) publication in Paleoceanography (doi:10.1002/2016PA002933). Carbonate system calculations for the downcore record determined based on the proxy CO32- values using the CO2SYS program are also included in this archive. Stable isotope geochemistry data measured by IRMS for individuals used in the ANSW and two additional study species (N. dutertrei) and N. incompta) are also included.
