ChAOS

The Changing Arctic Ocean Seafloor (ChAOS): How changing sea ice conditions impact biological communities, biogeochemical processes and ecosystems

Lead Investigator

  • Dr Christian März

    Lead Investigator, University of Leeds

    Christian März is Associate Professor for Biogeochemistry at the School of Earth and Environment, University of Leeds, and the Lead Investigator of the ChAOS project.

    A geologist by training and marine geochemist by choice, he has over the last seven years studied the behaviour of nutrients and metals in sediments of the Arctic Ocean and the North Pacific.

    Christian’s main focus is on the reconstruction of past environmental conditions from the archive of mud at the seafloor, and on the transformation and recycling processes of chemical elements like iron, manganese, carbon sulphur, phosphorus and silica (to name a few) that are key in biogeochemical processes.

    Within ChAOS, Christian will oversee the sampling and inorganic geochemical analysis of seafloor mud and the water within it – which is much more exciting than it sounds.
