This paper uses 699 single-grain (U-Th)/He ages in 12 different sizes of sediment to trace each clast back to its origins on hillslopes. We also developed a new analytical framework to analyze this big dataset, which incorporates some of the complexity of mountain landscapes. If you’re interested in sediment – where it comes from, how it breaks down, where it ends up – please check it out!

MSc student Maia Bellingham has had her thesis accepted, and will receive First Class Honors. Maia measured erosion rates across the Dobson catchment on New Zealand’s South Island using cosmogenic nuclides, and evaluated patterns in erosion and weathering across this rapidly-evolving landscape. She will present her work at the Geosciences New Zealand conference in Christchurch in late November, and will graduate shortly thereafter. Well done, Maia!
