Sediment descriptions and diatom counts from cores collected in northwest Scotland between 2022 and 2025. Data from sites in Raasay, Fearnmore, Loch Ewe, Reiff, and Inverkirkaig include collection dates, latitude/longitude, and sediment gouge descriptions. This dataset was produced by the Government Digital Service as part of a NERC grant to constrain relative sea-level history for testing ice-sheet and glacio-isostatic adjustment models.
Use Cases
- Reconstructing past relative sea-level changes based on sediment stratigraphy and diatom assemblages.
- Calibrating models of glacio-isostatic adjustment using field data from the former Minch Ice Stream region.
- Analyzing the interplay between ice-sheets and sea-level feedbacks based on geological records.
Strengths
- Data collection spans a multi-year period from 2022 to 2025.
- Covers multiple distinct geographic areas in northwest Scotland: Raasay, Fearnmore, Loch Ewe, Reiff, and Inverkirkaig.
- Includes precise location information (latitude/longitude) for each coring site.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific study areas in northwest Scotland.
