title: Results in the manuscript "Carbon source estimation of Banggai cardinalfish, Pterapogon kauderni otoliths using a novel tracer Δ14C: New implications for fish metabolism and otolith calcification"

description: These seven files contain data on the seawater temperature/salinity  and isotope value data in the manuscript  "Carbon source estimation of Banggai cardinalfish, Pterapogon kauderni otoliths using a novel tracer Δ14C: New implications for fish metabolism and otolith calcification".

 

(1)Seawater temperature and salinity data

sheet "temperature":

Column:

date(dd/mm/yyyy): Measurement date

temperature-tank 1 to 3: Seawater temperature of the three tanks used for the rearing of specimen. Note that some data are missing due to a malfunction in the measuring instrument.

temperature-tank average: Averaged temperature of the three tanks.

temperature-tank SD: Standard deviation of the temperature across the three tanks. SD is not calculated when only one temperature is available for the given date.

sheet "salinity":

Column:

date(dd/mm/yyyy): Measurement date

salinty: salinity of the tank seawater

d18Osw: predicted seawater δ18O value using equation obtained from regions dominated by same water mass (i.e. Tsugaru warm current) (Kodama et al., 2023). Specifically, following equation was used for calculation: δ18Osw=0.235×salinity-7.94

 

(2)pterapogon 14C

Column:

Samplename: Numbers to distinguish each specimen; same numbers are used for (1)Specimen data.

spawningyear: the year the specimen hatched

Samplingyear: the year the specimen was sampled

Averageyear: average of column “spawningyear” and “Samplingyear”, binned at 0.5-year intervals.

Averageyear_corrected: the average year offset by 1980 (i.e., averageyear – 1980), used as a predictor variable in the calculation of seawater DIC Δ14C for each specimen.

D14C: Δ14C value of whole otolith

D14Cerror: measurement error for Δ14C

 

(3)seawater 14C

Column:

samplingyear: the calendar year in which the water sample was collected. 

samplingyear_corrected: the sampling year offset by 1980 (i.e., samplingyear – 1980), used as a predictor variable in the linear regression analysis of sampling year against Δ¹⁴C. the sampling year offset by 1980 (i.e., samplingyear – 1980), used as a predictor variable in the linear regression analysis of sampling year against Δ¹⁴C. 

D14C: Δ14C value of water

D14C_error: measurement error for Δ14C

Study: specifies the study in which the measurement was conducted.

 

(4)diet 14C

Type: specifies the diet type, either moist pellet or krill

D14C: Δ14C value of water

D14C_error: measurement error for Δ14C

 

(5)pterapogon 13C

Column:

Samplename: Numbers to distinguish each specimen; same numbers are used for (1)Specimen data.

type: specifies whether the otolith sample was taken from the margin (i.e., the portion formed immediately prior to sampling) or from the core (i.e., the portion formed shortly after embryonic development).

d13c: δ13C value of the otolith portion (margin or core)

d18o: δ18O value of the otolith portion (margin or core)

 

(6) seawater 13C

Column:

samplingdate(dd/mm/yyyy): The date in which the water sample was collected

d13c: measured δ13C value

d18o: measured δ18O value

measurementmethod_d13c: specifies the machine used for IRMS measurement

 

(7)diet 13C

Column:

samplingdate(dd/mm/yyyy): Sampling date

d13c: measured δ13C value

d15n: measured δ15N value

type: specifies the diet type, either moist pellet or krill
