May 4-15, four of the COBS team led a MEDDLE experimental design workshop at CIBNOR (Centro de Investigaciones Biológicas del Noroeste) in La Paz, Mexico, combining MEDDLE with an experiment examining the effects of low pH on scallops during a simulated acute heatshock event.

The COBS working group is offering an experimental design workshop before Ocean Sciences in Glasgow in Feb 2026! 🌊 Join us for a day of learning about designing and analysing multiple stressor experiments without getting multiply stressed out. forms.office.com/Pages/Respon...

Date and time: 9:00–15:30, Sunday, February 8, 2026

Location: University of Glasgow, room details TBA

Title of the event: Designing multiple driver experiments

Conveners: Sinéad Collins, University of Edinburgh, Simin Gao, University of Edinburgh, Paul Renaud, Akvaplan-niva

Description: The MEDDLE resources were developed to help researchers design and carry out tractable and comparable multiple driver experiments. In this workshop, participants will learn how to use these resources to design multiple driver experiments. While the concepts and methods discussed can apply to many systems, examples used during the workshop will focus on manipulative experiments rather than observational data.

The workshop is geared mainly towards PhD students, postdocs, and ECRs new to multiple driver research, and focuses heavily on the rationale of different experimental designs, and analysis strategies for multiple driver experiments. A basic working knowledge of statistics is needed (regression analysis), and statistical analysis examples will use R. Participants should bring a laptop with R and R studio installed.

Topics include:
• Defining a research question
• Identifying relevant drivers
• Identifying biological traits and responses
• Experimental designs for multiple driver experiments
• Statistical analysis plans

Hosted by the SCOR project “Changing Ocean Biological Systems”, this free workshop will be led by Sinéad Collins, University of Edinburgh (UK), Simin Gao, University of Edinburgh (UK), Paul Renaud, Akvaplan-niva (Norway). Spaces are limited. If you would like to attend, contact Sinéad Collins (s.collins@ed.ac.uk) by January 15, 2026 to register your interest. Limited to 24 people, so please register early!

Please include a brief (<150 words) statement outlining (a) your experience carrying out Ocean acidification or multiple driver experiments (if any) and (b) how you plan to incorporate multiple driver experiments into your work

We will be teaching two free training courses at the BECoME-2025 conference in Hong Kong next month🌊 Course 1: Designing Multiple-Driver Experiments Course 2: Data Analysis for Multiple-Driver Experiments Join us! Apply through the conference website: www.become2025.com/registration

Training Course 1: Designing Multiple-Driver Experiments

BECoMe-2025 and SCOR’s Changing Ocean Biological Systems infrastructure group are hosting a free training course for researchers interested in learning how to design and carry out multiple-driver (i.e., multiple stressor) experiments that measure responses in microbes, plants, or animals. This training course will guide participants in using the MEDDLE resources to:

• Define a relevant research question
• Identify key drivers, biological traits, and responses
• Select an appropriate experimental design
• Develop a statistical analysis plan

Training Course Details

Time &Date: 9:30 am - 4:30 pm, 18 August 2025 (Monday)
Location: City University of Hong Kong
Participant Limit: 24 researchers (first-come, first-served)
Eligibility: Participants should have experience in designing and conducting single-driver experiments that study biotic responses (e.g. marine warming, ocean acidification).

Conveners: Christina McGraw, Sam Dupont, Sinéad Collins, Mridul K. Thomas, Peter Dillingham

Training Course 2: Data Analysis for Multiple-Driver Experiments

Researchers work hard to conduct interesting and challenging multi-driver experiments, but are often unaware of how best to analyse their data to take maximum advantage of these experiments. In this training course, participants will:

• Learn some of the common statistical challenges that appear in multi-driver experiments and how to solve them
• Work through an example R vignette for a multi-driver experiment
• Simulate an example dataset based on a proposed experiment
• Perform an appropriate analysis and visualise and interpret its output using “literate programming” via R markdown

Training Course Details

Time &Date: 9:30 am - 1:00 pm, 22 August 2025 (Friday)
Location: City University of Hong Kong
Participant Limit: 12 researchers (first-come, first-served)
Eligibility: Attendance at Training Course 1 (Designing Multiple-Driver Experiments) is required, as Training Course 2 builds directly on the concepts developed in the first training course. Participants should have experience with R and good knowledge of regression. Strong Python skills may also be considered, but Training Course 2 will be conducted using R.

Conveners: Peter Dillingham, Mridul K. Thomas, Sinéad Collins, Christina McGraw

Hello all! We're a working group studying how interacting drivers (or "multiple stressors") like temperature, acidification, etc. shape marine life. Follow us for new research and workshops, as well as tools to improve experimental design, data analysis, mathematical models, and more. 🌊
