Trace element–organic matter interaction in thawing arctic soils
Figure 1. Arctic landscape (Alaska)
We currently aim to evaluate the potential role of soil organic matter in the dynamics of trace elements in the Arctic. This is particularly essential since the recent thawing of soils in polar regions control the soil organic matter quality and quantity. Our goal is to evaluate the future behavior of trace elements comparing two similar sites (ecosystem, latitude...) with different annual average temperatures: Toolik in Alaska (–8 °C, continuous permafrost) and Abisko in Sweden (0 °C, discontinuous permafrost).
