Permafrost Carbon Network
When: 9 December 2018 | Where: Washington (US)
Contact: Christina Schädel
The latest and greatest on permafrost carbon science was presented in 18 science speed-talks to an audience of 120 scientists at the 8th Annual Meeting of the Permafrost Carbon Network. Many of these brief presentations laid the foundation for nine breakouts in the afternoon during which details for data collection, spatial data representation, analysis procedures, people to involve, and timelines were discussed.
For each of the breakout topics, we will provide a summary and timeline for members of the Permafrost Carbon Network, and we will host follow-up discussions via web-communication over the course of 2019 to ensure synthesis progress. During the meeting, we also highlighted the contribution and role of the Permafrost Carbon Network to the upcoming 2019 ‘Arctic Futures 2050’ conference that will identify needs of scientists and decision-makers and improve the dialogue between science and policy.
• Reduce uncertainty in carbon pools in permafrost and upscale carbon stocks in Arctic river deltas.
• Build a decadal-scale time series of ecosystem-atmosphere arctic/boreal carbon exchange through synthesis.
• Identify thaw-induced changes to the permafrost microbiome.
• Improve visibility and outreach opportunities on permafrost carbon to the public and decision makers.
NeAT ‐ Network for Arthropods of the Tundra (2)
The support from IASC has made it possible to strengthen the Network for Arthropods of the Tundra (NeAT) network through sessions at two major international conferences and a workshop. The workshop's goal was to plan the development of research protocols to stimulate further research activities of relevance to the IASC Terrestrial Working Group. The session at the Polar2018 conference resulted in critical connections to research groups working in Antarctica and thus strengthened this element of NeAT. It also facilitated an application for funding from UArctic for further network activities within NeAT – a proposal, which was granted in fall 2018 partly due to the activities supported by IASC.
The main activity supported by IASC was the organization of a workshop during the Arctic Biodiversity Assessment Congress in Rovaniemi, Finland 8-11 October 2018. The participants of the workshop designed three protocols (related to monitoring insect herbivory, image-based monitoring of tundra arthropods, and functional traits of predatory arthropods), and these will be further developed as part of the new funding from UArctic. NeAT also managed to liaise with Arctic freshwater ecologists, to form a stronger connection to this group, which is critical since many arthropod species have aquatic larval stages. In sum, the IASC support will have positive effects on the strength and activities of NeAT in the years to come.
• Strengthened Antarctic and freshwater components of the NeAT network.
• New and more substantial funding secured through UArctic.
• Three draft field protocols for comparative research formulate.

Wildlife species are of critical ecological and socio-economic and importance in Polar Regions, yet in the current context of global change they are experiencing increasing health challenges and the persistence of many species is uncertain. A better understanding of wildlife health status, including the diversity of pathogens and ecology of infectious and non-infectious diseases (e.g., toxins, immunity, and stress), is critical in order to anticipate, manage, and mitigate wildlife health issues at the poles. This workshop aimed to identify key scientific knowledge gaps in wildlife health and disease and to foster new research initiatives and collaborations at the interface between ecology and diseases in Polar Regions.
The importance of setting up carefully designed monitoring programs and of studies focusing on wild animal systems of particular relevance in the context of global change was identified. In this context, some particularities of polar host-parasite systems were outlined, such as the relatively simple species composition of their communities, their strong spatial structure and seasonality, and the fact that they are the subject of dramatic climate change effects. Issues linked to human health and human activities at the interface with wildlife were also identified as a future priority. It was decided to pursue interactions on these topics by the future organization of a workshop in 2020 and the writing up of a synthesis paper on the topic.
• Identification of key topics of broad interest in the current context of global change, notably the importance of considering host and parasite ecology and the role of interactions with human activities.
• Contributions to protocols and methodologies to address monitoring of polar wildlife health issues.
• Strengthening of the relationships between the Arctic and Antarctic/sub-Antarctic wildlife disease research communities to work on polar wildlife health questions.
T-MOSAiC (Terrestrial – Multidisciplinary distributed Observatories for the Study of Arctic Climate) is the result of 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 program MOSAiC 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.
The Frozen-Ground Cartoon
How does a reindeer experience climate change? Can a turkey melt? And why is research in the Arctic better than holidays on the beach? Two artists and twelve scientists provide a completely new perspective on the Arctic.
The Frozen-Ground Cartoon is a series of brand-new comics about permafrost, funded by the International Permafrost Association (IPA) with additional support from IASC (Terrestrial and Cryosphere WGs). The project has so far produced 22 pages of comics through an iterative process of exchanging ideas between two artists and thirteen scientists. The comics are available for free download through the project web page The Frozen-Ground Cartoon, in English and Swedish, and printed copies have so far been handed out to school kids and general public in Europe and North America.
(1) Distribute the comics as wide as possible.
(2) Work towards translations into more languages.
(3) Evaluate the effectiveness of the science communication through the comics, in collaboration with schools and pedagogic experts.
An Arctic Vegetation Archive (AVA)
When: 30-31 March 2017 | Where: Prague (Czech Republic) | Contact: Skip Walker
An Arctic Vegetation Archive (AVA) is needed to develop an effective Arctic terrestrial monitoring program and provide a standardized vegetation framework and data for an Arctic Vegetation Classification (AVC), land-cover mapping, ecological experiments, modeling, and biodiversity studies. Insufficient and non-standardized Arctic vegetation plot data are available to accomplish this task. The recently launched AVA and AVC aim to fill this knowledge gap.
The AVA and AVC would cover the entire Arctic tundra biome, the first for any of the world’s major biomes. This is achievable because the Arctic is the only biome that has its entire list of known vascular plants, mosses and lichens documented in up-to-date flora checklists developed by taxonomists within the CAFF Flora Group. Also the amount of vegetation plot data from the Arctic is still relatively modest compared to other biomes (approximately 31,000 plots). A large body of international experience and collaboration with database experts in other regions will also help to make the Arctic task feasible.
• An Arctic Vegetation Archive is an essential first step for developing an Arctic Vegetation Classification, monitoring change in terrestrial ecosystems, and developing a circumpolar framework for studying and modeling changes to the Arctic.
• Major progress on the AVA was achieved since the first AVA workshop in Krakow, including completion of the Alaska Arctic Vegetation Archive, and recent efforts toward using this in developing an Arctic Vegetation Classification.
• Many of the legacy data in the AVA were collected using non-standardized protocols. Going forward, new datasets should incorporate standardized methodologies for surveys, archiving, and analysis of Arctic plot data; workshops to develop these protocols should probably be proposed as part of the Arctic Observing Network activities.
Circum-polar Arctic Flux Workshop
Detailed observations of energetic, hydrological and chemical fluxes at the surface-atmosphere interface are necessary to understand and model coupling within the Arctic climate system. Global and regional models may represent Arctic state variables with relative accuracy, but it has been observed that they consistently fail to represent the observed magnitude and direction of energetic fluxes within the Arctic system. Some results of this failure are highly uncertain projections about the future state of the Arctic cryosphere and biosphere and high uncertainty about the fate of cryospheric carbon in the global atmosphere. To address these poorly constrained processes, coupling between the Arctic atmosphere, land surface and subsurface must be evaluated as an integrated system of energy, moisture and chemical exchange – each with unique observational challenges and process complexities in extreme Arctic environments.
