Abstract. Repeated sampling of spatially distributed river
chemistry can be used to assess the location, scale, and persistence of
carbon and nutrient contributions to watershed exports. Here, we provide a
comprehensive set of water chemistry measurements and ecohydrological
metrics describing the biogeochemical conditions of permafrost-affected
Arctic watersheds. These data were collected in watershed-wide synoptic
campaigns in six stream networks across northern Alaska. Three watersheds
are associated with the Arctic Long-Term Ecological Research site at Toolik
Field Station (TFS), which were sampled seasonally each June and August from
2016 to 2018. Three watersheds were associated with the National Park
Service (NPS) of Alaska and the U.S. Geological Survey (USGS) and were
sampled annually from 2015 to 2019. Extensive water chemistry
characterization included carbon species, dissolved nutrients, and major
ions. The objective of the sampling designs and data acquisition was to
characterize terrestrial–aquatic linkages and processing of material in
stream networks. The data allow estimation of novel ecohydrological metrics
that describe the dominant location, scale, and overall persistence of
ecosystem processes in continuous permafrost. These metrics are (1)
subcatchment leverage, (2) variance collapse, and (3) spatial persistence.
