Short communication: Updated CRN Denudation collections in OCTOPUS v2.3

Abstract. OCTOPUS v2.3 includes updates to CRN Denudation, adding 1311 new river basins to the CRN Global and CRN Australia collections. The updates bring the total number of basins with recalculated 10Be denudation rates to 5,611 and those with recalculated 26Al rates to 561. To improve data relevance and usability, redundant data fields have been removed, retaining only those relevant to each collection. Additional updates include the introduction of several new data fields, the latitude of the basin centroid and the effective basin-averaged atmospheric pressure, both of which improve interoperability with online erosion rate calculators. Other new fields record the extent of present-day glaciers and their potential impact on denudation rates, along with estimates of the percentage of quartz-bearing lithologies in each basin, providing a basis for evaluating data quality. The updated data collections can be accessed at https://octopusdata.org (last access: 1 February 2025) and have been assigned the following digital object identifiers (DOIs): https://doi.org/10.71747/uow-r3gk326m.28216865.v1 (Codilean and Munack, 2024a) for CRN Global and https://doi.org/10.71747/uow-r3gk326m.28216919.v1 (Codilean and Munack, 2024b) for CRN Australia.
