Central Alaska Cosmogenic Isotope Burial Age Data Collected 2020-2022
August 16, 2023
This data release includes three tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data from samples collected at four sites in central Alaska in 2020, prepared in 2022 at the University of Vermont (UVM), and measured at the Purdue Rare Isotope Measurement lab (PRIME) in 2022. The file "geology_siteLocations_centralAK_bender.csv" contains site locations in the NAD83 reference frame, and burial ages computed from raw data contained in the other files. All files are linked by the site_id_short field.

Yukon River incision drove organic carbon burial in the Bering Sea during global climate changes at 2.6 and 1 Ma
River erosion affects the carbon cycle and thus climate by exporting terrigenous carbon to seafloor sediment and by nourishing CO2-consuming marine life. The Yukon River–Bering Sea system preserves rare source-to-sink records of these processes across profound changes in global climate during the past 5 million years (Ma). Here, we expand the terrestrial erosion record by dating terraces along the

Late Cenozoic climate change paces landscape adjustments to Yukon River capture
Late Cenozoic cooling and changes in glacial–interglacial cycle tempo are thought to increase global rates of erosion starting ~3 million years ago (Ma). Bedrock rivers set rates and patterns of erosion in most landscapes, but constraints on river response to late Cenozoic climate change remain elusive. Here, we determine cosmogenic isotope and luminescence ages of well-preserved bedrock terraces
