The dataset is composed of three files providing the data used in the published paper Mueller et al. (2020) in the journal Nature Communications:
1.) data_experiment_1.csv (refers to experiment 1, a full-factorial marsh-organ experiment including manipulations of relative sea level, atmospheric [CO2] and nitrogen availability)
2.) data_experiment_2.csv (refers to experiment 2, a full-factorial marsh-organ experiment including manipulations of relative sea level and plant-species composition)
3.) data_field.csv (refers to the field data from the Salt Marsh Accretion Response to Temperature Experiment)
