K051 (my “event number”, the unique identifier for each science project) made it to Antarctica! Flew on a C17, only delayed by an hour, too. Thanks US Air Force and Antarctica NZ, now the fun begins.

This @gleonetwork.bsky.social workshop series is aimed at limnologists but it's open to all. We are targetting PhD students and postdocs across the environmental sciences.

@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.

We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. Details: September 23rd 16:00 CEST ; 14:00 UTC Description: Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

It takes patience to have a conversation about definitions as a collaboration begins... but it is important!
"Trophic state" in lakes is one of those concepts! It really makes a difference which definition we use... @mishafredmeyer.bsky.social

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

"Absolute teaching bliss" ☺️ is sending two bachelors students in a kayak to collect the first ecological data in over 70 years from a lake so protected, swimming and boating are off-limits. With special permission granted, they’re experiencing something virtually no living human has experienced.🚣‍♀️⛰️🌊

The takeaway from the StressRes workshop? Technical solutions alone won’t solve groundwater conflicts. What’s missing is a shared understanding of sustainability, clear priorities in times of scarcity, and communication that bridges science, policy, and the public. Learn more: tinyurl.com/StressRes

What did we learn? Sustainable groundwater management is anything but simple. We’re equipped with more information than ever—yet lack a shared understanding of what sustainable use really is. #Grundwasser #Bewässerung #Wasserpolitik #Digitalisierung #StressRes
