Data for Analysis of the Sensitivity of Erosion-Rate in Permafrost Landscapes to Changing Climatic and Environmental Conditions Based on Lake Sediments From Northwestern Alaska (1998-2022)

Erosion of landscapes underlaid by permafrost can transform sediment and nutrient fluxes, surface and subsurface hydrology, soil properties, and rates of permafrost thaw, thus changing ecosystems and carbon emissions in high latitude regions with potential implications for global climate. However, future rates of erosion and sediment transport are difficult to predict as they depend on complex interactions between climatic and environmental parameters such as temperature, precipitation, permafrost, vegetation, wildfires, and hydrology. Thus, despite the potential influence of erosion on the future of the Arctic and global systems, the relations between erosion-rate and these parameters, as well as their relative importance, remain largely unquantified. The data shared here was used to quantify these relations based on a sedimentary record from Burial Lake, Alaska, one of the richest datasets of Arctic lake deposits. The tabular data (csv) in this data submission includes variables that were used in multivariate analysis to detect the paleo-environmental proxies that are most strongly associated with erosion rates. The variables were measured through multiple studies (Abbott et al., 2010; Dorfman et al., 2015; Finkenbinder et al., 2015; Finkenbinder et al., 2018, King et al., 2021; Kurek et al., 2009).
