Unprecedented sea-ice minima enhances algal production deposited at the Arctic seafloor
Sea-ice in the Arctic is declining, with 2018 a particularly low year for ice extent, driven by anomalously warm atmospheric circulation in winter 2017/18. This is consistent with a multi-decadal trend to an earlier ice-free Barents Sea as climate change rapidly warms the Arctic. Here we investigate a N–S transect in the Barents Sea, crossing the Polar Front from Atlantic waters in the south to Arctic waters in the north, focusing on the organic …
New evidence for preservation of contemporary marine organic carbon by iron in Arctic shelf sediments
The protection of organic carbon through association with iron minerals (Fe R ) is an important factor in its stabilisation, long-term storage, and burial efficiency in marine sediments. However, large uncertainties still exist concerning the sources, lability, age, and composition of the organic matter associated with Fe R in natural sediments. Therefore, the timing and environmental setting of the carbon-iron bonding process remain elusive. Her…
Biogeochemical consequences of a changing Arctic shelf seafloor ecosystem
Unprecedented and dramatic transformations are occurring in the Arctic in response to climate change, but academic, public, and political discourse has disproportionately focussed on the most visible and direct aspects of change, including sea ice melt, permafrost thaw, the fate of charismatic megafauna, and the expansion of fisheries. Such narratives disregard the importance of less visible and indirect processes and, in particular, miss the sub…
Effects of climate change on a subtropical montane peatland over the last two centuries
Climate variability can induce rapid changes in peatland ecosystems, affecting both carbon cycling and vegetation succession. Diatoms are an important group of ubiquitous and diverse algae in peatlands. Until now, the responses of diatom communities to climate variability have rarely been explored in peatlands, especially in subtropical regions. In this study, monitoring and paleolimnological datasets were combined to decipher environmental chang…
Flexible education and the discipline of the market
This paper explores the contours of the current policy debate in Germany over higher education reform, and the issues it raises for an anthropological understanding of the role of higher education in late capitalist societies. In Germany as elsewhere, the massification of higher education was intimately bound up with the postwar trajectory of political capitalism, and its repercussions have continued to transform the moral economy of identity, ci…
