Description

StrathE2E2 is a dynamic model of the 'big-picture', whole ecosystem effects of hydrodynamics, temperature, nutrient additions, and fishing on continental shelf marine food webs.

Details

The StrathE2E2 model has two linked parts - a fishing fleet model and an ecology model. The fishing model integrates harvesting, discarding and seabed disturbance rates across a range of gears and passes the results into the ecology model.

The ecology model is a network of coupled ordinary differential equations representing the rates of change in organic detritus, dissolved inorganic nutrient, and coarse guilds of living biomass spanning microbes to megafauna. The equations include representations of feeding, metabolism, reproduction, active migrations, advection and mixing. Environmental driving data include temperature, irradiance, hydrodynamics, and nutrient inputs from rivers, atmosphere and ocean boundaries.

The package includes functions for parameter optimization, global sensitivity analysis, and Monte Carlo estimation of credible intervals for model outputs.

A fully developed and documented implementation for the North Sea is included in the package.

Example data package

Example outputs from the more computationally intensive model functions are provided as a supplementary data package.

The data package auto-installs when example data are first invoked. Alternatively, to install manually:
... from an R session ... install.packages("StrathE2E2examples", repos="https://marineresourcemodelling.gitlab.io/sran")

Once installed, load the package using ... library(StrathE2E2examples)
Open documentation on the datasets using ... help(StrathE2E2examples)
