T-MOSAiC - Implementation
Action Groups
These aim to bring together researchers to collaborate on common themes withinT-MOSAiC and define specific questions, activities & outputs
Chairs will build on existing & new projects and networks to link with similaractivities elsewhere in the circumpolar North, to address one or more elements of the T-MOSAiC Science Objectives

Database for molecular microbial data and environmental metadata
• ‘Omics data
• Arctic-Antarctic-Alpine
• Data archiving – and easy access for users facilitating biogeographic and comparative ‘omics studies
• Searchable database (limited to common variables)
• Additional information and tutorials
• Django ; Metadata and environmental data on GBIF as DwC EventCore
From to
Alison Murray, Maxime Sweetlove, Y. M. Gan, N. Youdjou, B. Danis, and A. Van de Putte
• Dissolved oxygen as a controlling variable in aquatic ecosystems• Arctic lakes as sentinels of global climate change• Connectivity and gradients from uplands to the sea
Quantifying the Hg originating from perennial frozen soil and thawing permafrost in subarctic and Arctic regions in a changing climate is of crucial interest to the scientific community and policy makers to assess the fate of Hg and associated risks in northern regions.

Oxygen concentrations vary in 3D in Arctic lakes, but as a starting point:
1 Dimensional Equation
is often used when one
oxygen sonde is
deployed in the upper
mixed layer
GPP - gross primary
production
R – respiration
F/zaml is flux across the
air-water interface and
flux from the thermocline
into the mixed layer
NEP = GPP – R
