PNBA - Mauritania sedimentary carbon and eDNA raw data

This dataset relates to the publication &lt;PLACEHOLDER&gt;. It contains sediment properties relating to carbon content and granulometry, eDNA metabarcoding and radionuclides required for the analysis. <strong>Dataset and variable description --------------------------------------------------------------------------------</strong> <strong> core-extraction.csv</strong><br> Contains properties related to the sediment cores. core_id - Unique identifier used for sediment cores habitat - Habitat where core was sampled. One of "Sand" (bare sediment, no vegetation), "Cymodocea" (vegetated by Cymodocea nodosa) or "Zostera" (vegetated by Zostera noltei) date - Sampling date (YYYY/MM/DD) lat - Latitude of sampling site (decimal degrees, WGS84) lon - Longitude of sampling site (decimal degrees, WGS84) sampling_depth - Depth reached by core sampler (cm) core_length - Length of sediment core, as measured in the lab after halving (cm) compaction - Compaction factor of sediment core <strong>loi-and-granulometry.csv</strong><br> Contains results from loss on ignition and dry sieving, used to study organic matter contents and granulometry. sample_id - Unique sample identifier. Created by concatenating core_id and the sample's middle depth core_id - Identifies which core the sample was retrieved from depth - Middle depth of the sample. All samples have a height of 2 cm. (cm) depth_corr - Middle depth of the sample, corrected for compaction volume - Sample volume (mL or cm3) volume_corr - Sample volume, corrected for compaction (mL or cm3) wet_sample - Wet sample weight (g) dry_sample - Dry sample weight (g) ground_sample - Weight of sample fraction used for loss on ignition (g) burned_sample - Weight of sample fraction used for loss on ignition, after submitting it to burning (g) water_content - Estimated water content of sample (fraction) om_content - Estimated organic matter content of sample (fraction) columns 90000-63000 μm to &lt;1 μm - Weight of sediment particles with size within range described in column name (g) mean_phi - Mean phi of sample (Krumbein phi, φ) percent_gravel - Sediment fraction (in weight) classified as gravel (fraction) percent_sand - Sediment fraction (in weight) classified as sand (fraction) percent_mud - Sediment fraction (in weight) classified as mud(fraction) <strong>radionuclides.csv</strong><br> Contains the results from gamma-ray spectroscopy core_id - Identifies which core the sample was retrieved from sample_id - Unique sample identifier. Created by concatenating core_id and the sample's middle depth depth - Middle depth of the sample. All samples have a height of 2 cm. (cm) depth_corr - Middle depth of the sample, corrected for compaction remaining columns - Element specific activity for element named in column (Bq/g). Columns with the suffix "_error" represent the measurement error (sigma = 2)
