    Description: Yedoma—extremely ice-rich permafrost with massive ice wedges formed during the Late Pleistocene—is vulnerable to thawing and degradation under climate warming. Thawing of ice-rich Yedoma results in lowering of surface elevations. Quantitative knowledge about surface elevation changes helps us to understand the freeze-thaw processes of the active layer and the potential degradation of Yedoma deposits. In this study, we use C-band Sentinel-1 InSAR measurements to map the elevation changes over ice-rich Yedoma uplands on Sobo-Sise Island, Lena Delta with frequent revisit observations (as short as six or 12 days). We observe significant seasonal thaw subsidence during summer months and heterogeneous inter-annual elevation changes from 2016–17. We also observe interesting patterns of stronger seasonal thaw subsidence on elevated flat Yedoma uplands by comparing to the surrounding Yedoma slopes. Inter-annual analyses from 2016–17 suggest that our observed positive surface elevation changes are likely caused by the delayed progression of the thaw season in 2017, associated with mean annual air temperature fluctuations.

    Description: Whilst the AtlantOS project is directed towards bringing together the existing, but currently disparate observing programmes in the Atlantic Ocean, there are still some gaps in terms of requirements for addressing the collection and curation of data around the Essential Ocean Variables. This deliverable will identify gaps and emerging observing networks. Here we use the term emerging network to classify science areas that are starting to gain importance with respect to EOV’s and their measurement and curation, or are existing small scale programmes or communities that might become more important in the future if we can find means of enhancing the collaboration among investigators/groups, increasing resources to the area or using new technological developments. In the AtlantOS project we have identified a number of areas in which there are gaps in our knowledge and where opportunities exist to enhance current small-scale networks. The scope of this document is to assess these networks, based on where we are now and where the networks could be in three and ten years’ time, respectively. An assessment of the state of the existing networks is useful to identify the level of international organisation and potential for further development in the future. We identify opportunities where synergies are possible with more established global projects, and where small levels of investment in resource and time for governance and coordination can productively and realistically develop the networks. We also identify if there are ways to develop coordinated approaches to metrology technology development. For this analysis, the networks have been allocated to one of the three groups outlined below.

    Description: Die Prozesse der Grundstoffindustrie sind verantwortlich für einen Großteil des industriellen Energie- und Stromverbrauchs in Deutschland. Welche technischen Möglichkeiten bieten sich in diesen Prozessen auf Flexibilitätsanforderungen des Stromsystems zu reagieren? Das vom BMBF geförderte Kopernikus-Projekt SynErgie untersucht die Flexibilität von Industrieprozessen. Ein Arbeitspaket, das aus dem Projektantrag des INFLUX Konsortiums hervorgegangen ist, hat nun umfassende Studie zu den Flexibilitätsoptionen in den Prozessen der Grundstoffindustrie veröffentlicht.
