| Summary: | Species of planktonic foraminifera exhibit specific seasonal production patterns and different preferred vertical habitats. The seasonality and vertical habitats are not constant throughout the range of the species and changes therein must be considered when interpreting paleoceanographic reconstructions based on fossil foraminifera. Accounting for the effect of vertical and seasonal habitat tracking on foraminifera proxies at times of climate change is difficult because it requires independent fossil evidence. An alternative that could reduce the bias in paleoceanographic reconstructions is to predict species-specific habitat shifts under climate change using an ecosystem modeling approach. To this end, we present a new version of a planktonic foraminifera model, PLAFOM2.0, embedded into the ocean component of the Community Earth System Model, version 1.2.2. This model predicts monthly global concentrations of the planktonic foraminiferal species: Neogloboquadrina pachyderma, N. incompta, Globigerina ... : The model data was created using the planktonic foraminifera model PLAFOM2.0, which was embedded into the ocean component of the Community Earth System Model version 1.2.2 (for more details see Kretschmer et al., 2018).The model results include monthly global concentrations (up to 250 m water depth) of the cold-water planktonic foraminiferal species Neogloboquadrina pachyderma, of the temperate-water species N. incompta and Globigerina bulloides, and of the warm-water species Globigerinoides ruber (white) and Trilobatus sacculifer. The environmental data comprises of the modeled monthly global concentrations of small phytoplankton, diatoms, zooplankton, large detritus, and chlorophyll as well as of the modeled monthly global temperature distribution. Note the files including the environmental data were created using the split command. To merge these files into one file the command cat (cat split-environmentalData.tar.gz0* > environmentalData.tar.gz) should be used and afterwards the file(s) can be ... |
