T-MOSAiC (Terrestrial – Multidisciplinary distributed Observatories for the Study of Arctic Climate) is the result of Terrestrial Working Group discussions at the IASC Arctic Science Summit Week in Prague (April 2017). T-MOSAiC aims to reinforce and extend the success of the IASC-supported MOSAiC program by taking a land-based perspective on human systems, geosystems and ecosystems, and their responses to sea-ice, oceanographic and climate change in the Arctic Ocean.
The main goal of the workshop was to scope out a Science Plan and to begin the preparation of an Implementation Plan, to be discussed in its final form during the Davos IASC T-MOSAiC workshop in June 2018. As discussed and planned at the Quebec City workshop, the secretariat for T-MOSAiC was opened at the University of Lisbon in February 2018, with an associated website.
Themes of T-MOSAiC
- Synthesis of environmental monitoring data from remote stations; measurements and models of permafrost, snow and glacier mass balance across different scales, and projections of the future state of the Arctic cryosphere.
- Estimates of past changes in Arctic geodiversity and biodiversity in land and inland water systems, measurements of current states (e.g. via transects, drones) and change.
- Estimates of how changing precipitation and temperature regimes are affecting ecosystem services such as drinking water and country foods, and geosystem services such as the permafrost foundation that underpins buildings and transport infrastructure.
