In the vast, remoteness of the Arctic, few have the opportunity to gather data on the environmental conditions over time or decipher the long-term effects of climate change. What is required? A considerable period to observe, a nearly autonomous method or actor for collection, a robust character to withstand the harsh surroundings. Researchers from Aarhus University in Denmark are tackling this issue through an interdisciplinary NordForsk project. At DanMAX beamline, the group will analyse a narwhal tusk to determine its chemical composition and biomineralization, both important potential markers of the changing environment.
