Abstract
OCTOPUS v.2 is an Open Geospatial Consortium (OGC) compliant web-enabled database that allows users to visualise, query, and download cosmogenic radionuclide, luminescence, and radiocarbon ages and denudation rates associated with erosional landscapes, Quaternary depositional landforms and archaeological records, along with ancillary geospatial (vector and raster) data layers. The database follows the FAIR (Findable, Accessible, Interoperable, Reusable) data principles and is based on open-source software deployed on Google Cloud Platform. Data stored in the database can be visualised, queried, and downloaded via a custom-built web interface and via desktop GIS applications that support OGC data access protocols. OCTOPUS v.2 hosts five major data collections. CRN Denudation and ExpAge consist of published cosmogenic 10Be and 26Al measurements in modern fluvial sediment and glacial samples, respectively. Both collections have a global extent and in addition to geospatial vector layers, the former also includes raster layers, including digital elevation model, gradient raster, flow-direction and flow-accumulation rasters, atmospheric pressure raster, and CRN production scaling and topographic shielding factor rasters. SahulSed consists of published optically stimulated luminescence (OSL) and thermoluminescence (TL) ages for fluvial, aeolian, and lacustrine sedimentary records across the Australian mainland and Tasmania. SahulArch consists of published OSL, TL, and radiocarbon ages for archaeological records and FosSahul consists of published late Quaternary records of direct and indirect non-human vertebrate (mega)fauna fossil ages that have been systematically quality rated. Supporting data are comprehensive and include bibliographic, contextual, and sample preparation and measurement related information. In the case of cosmogenic radionuclide data, OCTOPUS also includes all necessary information and input files for the recalculation of denudation rates using the open-source program CAIRN. OCTOPUS v.2 and its associated data curation framework allow the harnessing of valuable legacy data that would otherwise be lost to the research community. The database can be accessed at https://octopusdata.org (last access: 30 January 2022). The individual data collections can also be accessed via their respective digital object identifiers (DOIs).
