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
