Marine Climate Change Impacts and Solutions Laboratory
VISION:
Understanding the IMPACTS of climate change and finding SOLUTIONS for climate change.
In the middle of a climate crisis, we must continue gaining knowledge about the effects of global warming on fragile ecosystems such as the polar regions, while at the same time moving from knowledge to action seeking to apply or knowledge to find ways to mitigate climate change.
MISSION:
The Marine Applied Research Laboratory aims to improve our understanding of the processes that lead to carbon sequestration in the ocean: from primary productivity at the surface to carbon export to the deep sea.
Building on our strong knowledge on primary productivity measurements, carbon and nutrient uptake quantification, biodiversity estimates, grazing experiments, and biogeochemical modelling we:
Investigate the consequences of climate change in the Arctic Ocean for primary productivity, biodiversity and trophic transfer efficiency.
Assess the potential of macroalgae for long-term carbon dioxide removal and storage in the ocean.
