Geochemical XRF core scanning data of marine sediment cores from the Ryder 2019 expedition

Matt O'Regan

Relative geochemical elemental abundances of marine sediment cores collected during the Ryder 2019 Expedition to northwestern Greenland and the Lincoln Sea.

More specifically, the coring stations are from Petermann Fjord, Nares Strait, southern Lincoln Sea and Sherard Osborn Fjord (where Ryder Glacier drains the Greenland Ice Sheet).

The data were obtained with an ITRAX X-ray fluorescence (XRF) Core Scanner and provide information on the lithology and composition of the sediment cores.

Data description

The data were analysed at the SLAM (Sediment:Lake and Marine) Lab at the Department of Geological Sciences, Stockholm University, using an ITRAX XRF Core Scanner from Cox Analytical Systems. Analyses were made using a Mo tube (55 kV, 50 mA) at a step size of 2.0 mm with 15 s per point.

The datasets are included in one spreadsheet (xlsx) file. The first data table contains core names, location (latitude, longitude), length and water depth of each core. The other data tables contain the output from the XRF core scanner.

Data were collected during the Ryder 2019 expedition on board the Swedish icebreaker (I/B) Oden, which was organized by the Swedish Polar Research Secretariat.
