[Aqualist] OCTOPUS: An Open Cosmogenic Isotope and Luminescence Database

[Alexandru Codilean]

Dear Friends

A few days ago we have made available online a new open and global database of cosmogenic radionuclide and luminescence measurements in fluvial sediment (OCTOPUS).

With support from the Australian National Data Service (ANDS) we have built infrastructure for hosting and maintaining the data at the University of Wollongong and making this available to the research community via an OGC compliant Web Map Service.

The cosmogenic radionuclide (CRN) part of the database consists of Be-10 and Al-26 measurements in fluvial sediment samples along with ancillary geospatial vector and raster layers, including sample site, basin outline, digital elevation model, gradient raster, flow direction and flow accumulation rasters, atmospheric pressure raster, and CRN production scaling and topographic shielding factor rasters. The database also includes a comprehensive metadata and all necessary information and input files for the recalculation of denudation rates using CAIRN, an open source program for calculating basin-wide denudation rates from Be-10 and Al-26 data.

The luminescence part of the database consists of thermoluminescence (TL) and optically stimulated luminescence (OSL) measurements in fluvial sediment samples from stratigraphic sections and sediment cores from across the Australian continent, and includes ancillary vector and raster geospatial data.

OCTOPUS can be accessed at: https://earth.uow.edu.au

We have also submitted a manuscript describing the database in detail to the open access journal Earth System Science Data. The paper is now accessible and open for interactive public discussion until 01 May 2018 at:

https://www.earth-syst-sci-data-discuss.net/essd-2018-32/

You are invited to download the data and take part in the discussion.

Thank you
Tibi
