The dataset of surface sediments consists of one table, available as Excel spreadsheet (.xslx), tab-separated text (.txt) file, and as zipped GIS shapefile (in WGS84 geographic coordinate system):
- CASCADEsurfsed_v2.xlsx
- CASCADEsurfsed_v2.txt
- CASCADEsurfsed_v2_GISshp.zip
##### Data sheet structure
Each row in the CASCADE data sheet for surface sediments represents one oceanographic station, for which one or several carbon parameters were analyzed. All data and meta data for each station and measurement have are organized as columns in the data table. More detail about all parameters is provided in the companion manuscript.
###### Columns for ID and georeference
1. CASCADE entry ID
2. Sample code (as reported by data source)
3. Latitude (decimal degrees)
4. Longitude (decimal degrees)
5. Upper sample depth (cm)
6. Lower sample depth (cm)
7. Water depth (m b.s.l.)
8. Water depth based on IBCAO (m b.s.l.)
9. Expedition or vessel name
10. Sampling year
###### Carbon and Nitrogen (CN) data
11. OC (%)
12. TN (%)
13. OC/TN
###### Carbon isotopes
14. δ¹³C (‰ VPDB)
15. Δ¹⁴C (‰)
###### Biomarkers
16. n-alkanes C21-31 (µg g-1 OC)
17. n-alkanes C27,29,31 (µg g-1 OC)
18. n-alkanoic acids C20-30 (µg g-1 OC)
19. lignin phenols (mg g-1 OC)
###### References
20. Citation of CN data
21. Citation of δ¹³C data
22. Citation of Δ¹⁴C data
23. Citation of biomarker data
###### Quality parameter and meta information
24. Sediment sampler (e.g. grab sampler, multi corer, etc)
25. Sample storage (0 for unknown, 1 for frozen, 2 for refrigerated)
26. CN measurement (method of analysis)
27. ¹³C measurement (method of analysis)
28. AMS label
