Multi-factor experiments are increasingly used in marine sciences, so that the SCOR Working Group 149 released a Best Practices guide to design and analysis of multi-driver experiments in 2019.

As multi-factor experiments are also part of the Nansen Legacy’s experimental programme, the Nansen Legacy organized a one-day workshop on October 12th 2020 together with the ARCTOS network. Several members of the SCOR Working Group on Changing Ocean Biological Systems participated with presentations and in the discussion about Best Practices Guide for multi-factor experiments.

Constraints on traveling led to an unusual workshop format whereby multiple in-person nodes around Norway and Denmark were linked via Zoom where break-out working groups were enabled, and lectures and practical work facilitated. In all, twenty-three PhDs, postdocs and technicians and several senior researchers participated, along with course leaders, John Havenhand (Tjärnö Marine Biological Station, Gothenburg University, Sweden), Christina McGraw (University of Otago, New Zealand), and Paul Renaud (Akvaplan-niva/UNIS).
