A toothy temporal map of Arctic climate change

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.
