Sport climbing champion wins water science prize

New Zealand sport climbing champion Sarah Tetzlaff has won the Waikato Regional Council Prize in Water Science for 2023. The prize recognises a University of Waikato student who shows outstanding ability in water science papers taught in the Faculty of Science and Engineering.
Sarah combines full-time study with more than 20 hours per week training in her quest to qualify for the Paris 2024 and Los Angeles 2028 Olympic Games, which means she often flies overseas to compete at international climbing events.
In fact, she has recently returned from Bern, Switzerland where she competed in New Zealand’s first world championship climbing team. She broke her own New Zealand open female record of 9.29 seconds by completing a climb in 8.98 seconds.
Despite her busy training schedule, Sarah applies her passion for water science to tertiary study and has recently completed a Bachelor of Science degree majoring in environmental science. She’s now studying a Master of Science (Research) degree she began in July at the University of Waikato.
Majoring in environmental sciences, Sarah’s master’s researches the link between shallow groundwater and algae growth in the near-shore shallow water zone (<1m depth) along Lake Tarawera. She is investigating whether this groundwater influences algae growth and also quantifying the general level of energy production in this near-shore zone, which Sarah says has never been done before in New Zealand.
This knowledge may help us understand the energy production at the bottom of the food web (all the connected food chains) in lake ecosystems.
Sarah says her academic interest in water emerged from studying papers about Antarctica and water processes in rivers and glaciers: “I found these papers extremely fascinating. They really opened my eyes to how amazing water is and its importance in the climate, oceanic and terrestrial systems. Since then, I have taken all the available water science papers at Waikato University.”
