This project aims to unravel the biogeochemistry of vanadium in modern marine sediments for use as a tracer of ancient oxygen concentrations in the oceans of the early Earth. This project will generate fundamental knowledge on the behaviour of vanadium in modern marine sediments by applying advanced analytical tools for imaging its concentration and chemical form at ultra-high resolution. This information is critical for accurate interpretation of the geological record to infer the oxygen concentration of the oceans at various points in Earth's history. This interdisciplinary project will facilitate strong collaboration between Australian and Danish researchers in the field of marine geochemistry and paleoceanography.

该项目旨在揭示现代海洋沉积物中钒的地球化学，以作为早期地球海洋中古代氧浓度的示踪剂。该项目将通过应用先进的分析工具以超高分辨率对钒的浓度和化学形式进行成像，获得关于钒在现代海洋沉积物中的行为的基本知识。这些信息对于准确解释地质记录以推断地球历史上不同时期海洋的氧浓度至关重要。这一跨学科项目将促进澳大利亚和丹麦研究人员在海洋地球化学和古海洋学领域的密切合作。
