Steady states of marine ecosystem model

Steady periodic states of marine ecossystem model (N model, as described in I. Kriest, S. Khatiwala, and A. Oschlies. Towards an assessment of simple global marine biogeochemical models of different complexity. Progress in Oceanography, 86(3-4):337–360, 2010) simulated by software Metos3d (J. Piwonski and T. Slawig. Metos3D: the marine ecosystem toolkit for optimization and simulation in 3-d – part 1: Simulation package v0.3.2. Geoscientific Model Development, 9(10):3729–3750, 2016) after 10'000 years model time, starting with constant initial distribution, as described in the abovementioned Piwonski Slawig reference. 1000 parameter vectors generated by latin hypercube sampling and corresponding states for one time instant each, see also M.
