    dct:description """This dataset consists of output from a computer model that predicts responses 
of 69 functional groups from plankton to whales to changing fishing pressure. 
Scenarios are run using the newly built plug-in (see report) that allows for 
an assessment of the effect of model parameter uncertainty. The base model is 
the ICES key-run of EwE for the North Sea described here 
`http://data.cefas.co.uk/#/View/2847`_. Format of the data: Zipped csv files 
covering the hindcast period 1991-2013 (inclusive) with 20 year forecasts. 
Output includes annual average values for the whole North Sea: For both 
functional groups and fishing fleets: landings (tonnage and value, £), 
discards (tonnage),for functional groups only: biomass (tonnage) and fishing 
mortality (split by landings and discards), for fishing fleets only: fishing 
effort relative to 1990. Also identified are 'choke species' that lead to 
closure of fisheries. The report (pdf) describes the development of a tool for 
assessing the effect of model parameter uncertainty on the performance of 
management options simulated using an ecosystem model. It provides the 
rationale, description of methods and algorithms, and a step-by-step guide for 
users of the tool. While the interface of the tool is designed to be user 
friendly, the setup of input files and its application requires a thorough 
understanding of the parameterisation of Ecopath models, advanced experience 
with Ecosim and understanding of Management Strategy Evaluation procedures.
