# StrathE2EPolar 1.0.0

* Version 1.0.0 was developed from StrathE2E2 version 3.3.0.
  The latter is a food web/ecosystem model for temperate shelf
  seas. StrathE2EPolar is designed for polar shelf sea which are
  affected by sea ice. The development includes:

  * Addition of time-varying ice extent, cover and thickness,
    and air temperature data to the list of driving data.

  * Addition of state variables to represent nutrients, detritus
    and algae in the ice, and their connections to the rest of
    the food web.

  * Addition of state variables to represent the dynamics of
    maritime mammals (polar bears).

  * Addition of representation of ice-depenedency of feeding
    and active migrations by top predators.

  * Version 1.0.0 contributes to the submitted publication:
