The Norcoast25 - a regional marine radiocarbon calibration curve for the period Bølling to the Early Holocene for the Norwegian coast (14.4–11.0 ka BP).

<p>This is data to the Norcoast25 calibration curve used to calibrate marine 14C ages to calendar years along the coast of Norway. All details of how the Norcoast25 calibration curve was constructed are explained in the related publication (see below). The data is stored in two different versions: The file Norcoast25.14c can be downloaded to the calibration program OxCal. The file Norcoast25.txt contains the same data. The files have three columns; Column A is the calibrated date BP (CAL_BP), Column B is the 14C age (14C_age) and column C is the error to the 14C age (14C_Error). </p>
<p>To calibrate a 14C date with the Norcoast25 curve use the program OxCal, download the file Norcoast25.14c to the bin folder of OxCal, ex. C:\Oxcal\bin. Then, to calibrate a 14C age with the Norcoast25 curve you must write it into the OxCal code. For instance: </p>
<code>Plot()
{
Curve("Norcoast25","Norcoast25.14c");
R_Date("TUa-1902",13110,125);
}; </code>
<p>It is also possible to use Norcoast25 with the calibration program CALIB, but then you would have to rename the Norcoast25.14c file to marine20.14c in the downloaded version.</p>
