Physical properties of marine sediment cores from the Ryder 2019 expedition

Matt O'Regan

Bulk Density and magnetic susceptibility measurements performed on 25 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 provide basic information on the lithology and composition of the sediment cores.

Data description

The dataset includes physical properties measured at 1 cm intervals with a GeoTek Multi-Sensor Core Logger: Bulk Density (g/cm³) and Magnetic Susceptibility (MS1, SI × 10⁻⁵), mass normalised Magnetic Susceptibility (m³/kg × 10⁻⁸).

The dataset is included in one spreadsheet (xlsx) file with 26 data tables.

The first data table contains the core names, location (latitude, longitude), length and water depth of each core. The other data tables contain the physical property data for each core. Each of these tables has seven columns:

• Core Depth (m)
• Section
• Interval (cm)
• Core thickness (cm)
• Bulk Density (g/cm³)
• Magnetic Susceptibility (SI × 10⁻⁵)
• Mass normalised Magnetic Susceptibility (m³/kg × 10⁻⁸)

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.
