3D X-ray computed tomography gray value and age model datasets of Calaguas and Palaui coral cores (Philippines)

The datasets in this article contain raw data of the coral age model, gray values, and SST matching of the Calaguas and Palaui coral cores. There is a total of nine (9) datasets: 1. CS1O – segment 1 (top) of Calaguas coral core matched with OISST 2. CS2O – segment 2 of Calaguas coral core matched with OISST 3. CS3aO – segment 3a of Calaguas coral core matched with OISST 4. CS3bE – segment 3b of Calaguas coral core matched with ERSST 5. CS4E – segment 4 of Calaguas coral core matched with ERSST 6. CS5E – segment 5 of Calaguas coral core matched with ERSST 7. PS1O – segment 1 (top) of Palaui coral core matched with OISST 8. PS2O – segment 2 of Palaui coral core matched with OISST 9. PS3O – segment 3 of Palaui coral core matched with OISST Each dataset contains four (4) .csv files: a. data – has 2 columns, pixel no. and gray value. This is the output of the 3DXCT analysis. Gray values were taken from top to bottom of each segment, as shown in Fig. 1. b. target – has 2 columns, date (in number format = number of days from January 1, 1900) and SST in degC, based on OISST [1,2] or ERSST [3]. These are the daily record of SST of the study site. c. time model – has 2 columns, pixel no. and date (in number format). All tie points between gray values and SST are recorded in this file. d. data with ages – has 3 columns, pixel no., gray value, and date (in number format). This is the output of gray value vs. SST matching, i.e., the resulting age model of each coral core segments. The data, target, and time model files can be directly used as input files in the QAnalySeries software [4] to view or edit the gray value vs. SST matching.
