sandeel population model for the North Sea

example_of_model_output paper

Summary

This code produces model results in 'Exploring the Influence of Food and Temperature on North Sea Sandeels Using a New Dynamic Energy Budget Model' by Alan MacDonald, Douglas C. Speirs, Simon P. R. Greenstreet and Michael R. Heath. https://www.frontiersin.org/articles/10.3389/fmars.2018.00339/full

Running the model produces

  1. a text file of sandeel individual data, "Individuals.txt".
  2. A series of plots showing changes in cohort abundance, mean length and mean weight.
  3. A csv file,"Results.csv", which contains the plotting data.

*Note that sometimes the user will need to run the 'ModelRun.R' script twice to produce all plots.

Running instructions

To run, simply run the 'ModelRun.R' script.

The user can parameterise the model by changing line 30 to

Parameterisation="T"

or run the model by changing line 30 to

Parameterisation="F"

User input

The directory USER_INPUT allows the user to change the run time, the age and year class of the sandeels and alter parameter values.
