Acclimation of phytoplankton Fe:C ratios dampens the biogeochemical response to varying atmospheric deposition of soluble iron

Dissolved iron (dFe) plays an important role in regulating marine biological productivity. In high-nutrient, low-chlorophyll regions (> 33% of the global ocean) iron is the primary growth-limiting nutrient, and elsewhere iron can regulate nitrogen fixation and growth by diazotrophs. The link between iron availability and carbon export is strongly dependent on the phytoplankton iron quotas, or cellular Fe:C ratios. This ratio can vary by more than an order of magnitude in the open ocean and is positively correlated with ambient dFe concentrations in sparse field observations. The Community Earth System Model ocean component was modified to simulate dynamic, group-specific, phytoplankton iron quotas (Fe:C) that vary as a function of ambient iron concentration. The simulated Fe:C ratios match the spatial trends in the observed  Fe:C ratios. Acclimation of phytoplankton Fe:C ratios dampens the biogeochemical response to varying atmospheric deposition of soluble iron, compared to a fixed ..., This dataset contains NetCDF output from the CESM v1.98 model, ocean only, Biogeochemical Elemental Cycling. The files presented are a 20 year average for the final 20 years of a 300 year simulation (Years 281-300). Files are provided for every simulation conducted for the results of the paper. This includes the optimal variable stoichiometry model and  fixed Fe:C versions with values of 3, 7, 10 for the four iron deposition simulations (onlyBC is Pyro Only, noBC is Dust Only, CESM2opt is Pyro + Dust, BCx2 is 2xPyro + Dust). 
Supplemental runs include a limited variable run (with parameterization from Moore et al., 2004) and two fixed runs where Fe:C is set at 5 and 6, all three with the CESM2opt (Pyro + Dust) forcing.
The fec_full_diaz.csv file contains the observational data of phytoplankton Fe:C including the following fields: num (unique location number), UniqueStn (unique station name), CellType3 (aflag (autotrophic flagellate), diatom, diaz(diazotroph), or NA), CellTypeNum (1 = di..., These .nc files can be opened via Panoply, Python, or any other program that can import NetCDFs. The excel file can be opened using Microsoft Excel, Google Sheets or any other program that can import CSVs. The .m and .mat files can be viewed and executed with MATLAB, or viewed with VSCode or Python using the Scipy or PyTables libraries.
