We would like to let you know that the SCOR Working Group 149 on "Changing Ocean Biological Systems (COBS)" has launched a new tool used for running best practice experiments in ocean research. The new tool is called MEDDLE: The Multiple Environmental Driver Design Lab for Experiments, and includes learning material/ videos, an experimental design tool to help scientists create accurate and statistically meaningful single and multi-driver experiments, and a simulator that allows users to run several virtual laboratory experiments by setting the combined levels of the drivers, choosing the number of replicates, and considering natural variability. 

You can find more information about MEDDLE from the dedicated website: https://meddle-scor149.org/, which includes a handbook on using MEDDLE.
