[OBSOLETE] OCTOPUS – CRN International

<p>Database of published cosmogenic&nbsp;¹⁰Be and&nbsp;²⁶Al concentrations from modern river sediment and basin-averaged denudation rates inferred from these data.</p> <p>Ancillary spatial data includes: sample site location (point), basin outline (polygon), digital elevation model (raster), D8 flow direction and flow accumulation grids (raster), topographic gradient (raster), atmospheric pressure (raster), and cosmogenic nuclide production scaling factor and topographic shielding grids (raster). The vector spatial data uses the WGS84/Pseudo-Mercator (EPSG: 3857) projected coordinate reference system. The raster data uses the WGS86/UTM projected coordinate reference system, UTM zones depending on the extent and location of each data package.</p> <p>Sample metadata is comprehensive and includes all necessary information and input files for the recalculation of denudation rates using the&nbsp;<a href="https://doi.org/10.5194/esurf-4-655-2016">CAIRN open source calculation tool</a>&nbsp;that can be obtained here:</p> <p><a href="https://github.com/LSDtopotools/LSDTopoTools_CRNBasinwide">https://github.com/LSDtopotools/LSDTopoTools_CRNBasinwide</a></p> <p>All denudation rates were recalculated and harmonised using CAIRN. The extent of the data is global, excluding Australia.</p> <p>The data collection is discussed and documented in the following publication:</p> <p>Codilean, A. T., Munack, H., Cohen, T.
