New discoveries in tree ring dating

Wednesday, 28 October 2026

Every tree keeps a diary. One ring for every year to record exactly how the seasons play out. Current student and Patricia Jensen Science Scholarship recipient, Madeleine Hatfield, is learning how to analyse tree rings to understand seasonal changes over time, helping climate scientists read Australia’s past.

Studying a Bachelor of Science (Advanced), Madeleine recently learnt the tools of dendrochronology under the supervision of alumna and researcher, Associate Professor Danielle Verdon-Kidd, finding a simpler way to count tree ring boundaries.

“Madeleine’s contribution to this project was outstanding. Her work identifying the use of coloured chalk to improve the visibility of tree ring boundaries has the potential to make ring measurements more accurate and efficient, particularly in challenging samples,” Associate Professor Verdon-Kidd says.

Improvements like Madeleine’s can have a big impact, helping researchers build clearer records of Australia’s past climate changes and strengthening the science that guides future environmental decisions.

Providing students with opportunities to participate in research during their degree is incredibly important,”

It allows them to apply their classroom learning to real-world problems, develop critical thinking skills and gain first-hand experience in the discovery process, hopefully sparking an interest in further research. Scholarships play a vital role in making these opportunities accessible, particularly for students balancing study, work and other commitments.”

Madeleine’s future is bright and she is now thinking about further study after completing her degree. Grateful for the support of the Patricia Jensen Science Scholarship, the extra time and reduced financial pressure allowed Madeleine to focus more on her research and less on paid work.

It also helps her cover the costs of outdoor field trips, which are an essential part of her studies in Earth Science and Biodiversity Conservation.

“Working two jobs, attending classes and taking time out for field trips is a lot and it takes a toll on your mental health sometimes,” Madeleine says.

It really boosted my confidence knowing that someone understands my situation and wants to see me succeed. I think it’s important to stand up for what you believe in. The late Patricia Jensen was a teacher and very involved with politics and her community – exactly the kind of person I want to be. I hope she would be proud of what I have already been able to achieve during my studies.”
