This dataset contains all files required to run simulations of 6 acoustic-trawl surveys based on spatio-temporal distribution of mackerel and herring in the Nordic Seas in 2012, generated using the NORWECOM.E2E model (Skogen, M. D., & Søiland, H. (1998). A user's guide to NORVECOM V2. 0. the norwegian ecological model system.). The simulations were used in the PELFOSS project by the Norwegian Institute of Marine Research. Included for each year of each species are two NetCDF-files; (1) one file containing the superindividuals generated by the model, and (2) one file containing interpolated area density. The NORWECOM.E2E model was run through the years 2010-2012, but only the data from 2012 are included in this dataset, in order to reduce impact of the initial state. The NORWECOM.E2E model files are located in the folder "model" with sub-folders for each species. Also included are stratum polygons for each of the 6 surveys to be simulated based on the NORWECOM.E2E model files. The stratum polygons are saved as text files containing well-known text (WKT) multipolygons in the folder "stratum". In two of the simulations, the catches from the fishing fleet were used to allocate effort in the strata. Included in the dataset are one file of the catches from 2012 for each species given by date, position and catch weight. Note that the files are compressed in a zip-file (445 MB ), and will expand to 6.9 GB when unzipped.
