Climate change and mercury are two of the greatest threats to Arctic marine predators like narwhals and beluga. Not only do these stressors exert individual impacts, but they also interact to cause often unpredictable consequences. Long-term datasets and access to relevant biological tissues and associated biomarkers are rare in Arctic species and thus hinder our understanding of stressor effects. In this webinar I will discuss the use of narwhal tusk and beluga teeth as unique and valuable archives of historical data on mercury and climate change.

The Arctic is warming much faster than the rest of the planet. This warming can be amplified or attenuated by natural climate variability. However, the sparse meteorological and instrumental data in the Arctic, when available, do not extend beyond the last 50 years. This reality prevents an adequate understanding of the climate system in this highly vulnerable region. To overcome this lack, we use annually laminated sediments (varves) at the bottom of Arctic lakes. This allows us to go back in time, typically several millennia before present, with annual temporal resolution.
