The CAMLR Scientific Committee in 2017 reviewed the scientific background document SC-CAMLRXXXVI/ BG/28. Germany was asked to carry out further work, in particular as regards the issues and questions raised at WG-EMM-17 and SC-CAMLR-XXXVI with respect to the WSMPA proposal (SCCAMLR- XXXVI, Annex 6, §§ 5.1-5.14). Chapter 1 reflects on the recommendations concerning the suitability of some data layers for Marxan analyses, such as the data layer representing the distribution of Antarctic krill larvae (SC-CAMLRXXXVI, Annex 6, §§ 5.9 - 5.10). Chapter 2 discusses the recommendations concerning the suitability of the cost layer developed for the WSMPA Marxan analysis (SC-CAMLR-XXXVI, Annex 6, §§ 5.10 and 5.12) and presents the updated cost layer. Chapter 3 provides a new data layer on juvenile Antarctic toothfish, and Chapter 4 presents a robustness testing of the WSMPA Marxan model.
