Comprehensive data dump for sample AA-27756
Sample
| Sample name | Core name | Top depth (m) | Bottom depth (m) | Total organic carbon (%) | Carbon type | Sample preparation method | Fraction modern | δ13C (‰, PDB) | Age (14C yr) | Age uncertainty (14C yr; 1σ) | Comments |
|---|---|---|---|---|---|---|---|---|---|---|---|
| AA-27756 | IWSOE70-3-7-1 | 2.0 | 2.0 | None | Benthic foraminifera (Globocassidulina subglobosa) | Carbonate hydrolysis | 0.036195883 | None | 26660.0 | 490.0 | Stolldorf et al. (2012) note that this age (sample AA-27756) was reported incorrectly by Anderson & Andrews (1999), but is corrected here. |
