Work package 2 (WP2) aimed to identify, collect, and evaluate information not usually considered for assessment and management. Deliverable 2.4 (D2.4) contains a list of protocols that describe the final implementation of the novel data into models within each case study (CS). Each of these protocols is written in a similar way as a “Material and Methods” section in a paper. D2.4 is structured as follows for each CS: first a summary of general CS aims, models implemented and novel data explored. This summary ends with an explanation about why this data is considered novel and the definition of the protocols developed in this CS. The number of protocols in each CS ranges between one and three. In some CSs different novel data types were considered but all of them were implemented in the same model. In these cases, only one protocol was written. When more than one model was considered the protocol number equals the number of models. The exception was the Chatham Rise CS, where two different models (EwE and Atlantis) implemented the same novel data types and all were reported in a unique protocol; and SWW-Iberian Peninsula CS were different novel data types were implemented in GADGET although for each data type the GADGET model was different and 3 protocols were presented. The model implementation describes how the data is influencing the model structure, i.e. whether is used to test the validity of assumptions or used to fit parameters; followed by a description of the ecosystem process and how it is related with the novel data. The focus of this section is on the novel data and related processes avoiding extending it to a full model description already presented in other deliverables in WP4 and WP5. A total of 16 different protocols were written. These protocols can be useful to the scientific community to implement similar data in ecosystem models. After the implementation of novel information into assessment models, the utility of this information will be evaluated in a critical report (D2.5). This report will be a synthesis of all the work in WP2 and it will consider the usefulness of each information type
