Coastal permafrost erosion, organic carbon and nutrient release to the arctic nearshore zone (COPER) Permafrost Erosion Arctic permafrost coasts account for 34% of the coasts of the Earth and are extremely [...] extremely vulnerable to climate change, because the frozen bluffs lose the cohesion provided by the permafrost matrix upon contact with seawater and are instantly washed away by incoming waves. With warming [...] e the spatial variability of particulate and dissolved organic carbon and nutrient contents in permafrost sediments and ground ice as well their sediment characteristics through cross-shore sampling transects

Coastal Permafrost Profile About 34% of the world's coasts are affected by Arctic permafrost and are particularly sensitive to climate change. The frozen bluffs lose the cohesion provided by the permafrost [...] as well as ecosystem services of permafrost coasts. Using a multitude of methods we investigate: the content of particulate and dissolved organic material in permafrost sediments and their bottom ice and [...] ble to quantify the amount of eroded sediment and organic material more accurately. The group "Permafrost Coasts" investigates the velocity and character of sediment and organic matter transport into the
