Dataset provided in .xlsx, .csv, and .ods formats. Software/equipment used to create/collect the data: Body impedance measurements were subsequently performed with a handheld bioelectrical impedance spectroscopy (BIS) analyser (SFB7, Impedimed, Brisbane, QLD, Australia) following procedures outlined in Kophamel et al. (2023). The BIS device measured resistance and reactance at 256 logarithmically-spaced frequencies in the range 3-1000 kHz, and device calibration was verified daily during fieldtrips. Ten replicate impedance measurements with an interval of five seconds were recorded to account for intra-animal variability, with each measurement taking 800 ms. The extracted data of interest were resistance at infinite frequency (Rinf, predictor of total body water and fat-free mass), resistance at zero frequency (R0, predictor of extracellular water), intracellular resistance (Ri, an index of intracellular water); and, for comparison with studies using single-frequency BIA (SFBIA) devices, resistance at 50 kHz (R50), reactance at 50 kHz (Xc50) and phase angle at 50 kHz (PhA50). Software/equipment used to manipulate/analyse the data: Recorded impedance data were analysed using Bioimp software (v5.4.0.3, ImpediMed Ltd, Brisbane, QLD, Australia), that calculates resistance (R, ohm), reactance (Xc, ohm) and phase angle (PhA, arctangent Xc/R, degrees) at each frequency and uses Cole analysis to obtain estimated resistance at infinite frequency (Rinf) and at zero frequency (R0) (Cornish et al. 1993) (for further details please refer to the manufacturer's website: https://www.impedimed.com/). The extracted parameter of interest was resistance at 50 kHz (R50) for comparison with studies using the more affordable SFBIA devices. AT (kg) for each individual turtle was estimated using the equation derived in Kophamel et al. (in press).&rft.creator=Kophamel, Sara &rft.creator=Ward, Leigh C. &rft.creator=Mendez, Diana &rft.creator=Ariel, Ellen &rft.creator=Bell, Ian &rft.creator=Shum, Edith &rft.creator=Munns, Suzanne L. &rft.date=2023&rft.relation= https://doi.org/10.1093/conphys/coac043&rft.relation=https://doi.org/10.1111/cobi.13724&rft.relation=https://doi.org/10.1002/ece3.9610&rft.relation=http://doi.org/10.1086/722451&rft.relation=https://doi.org/10.3354/esr01248&rft.coverage=143.656294,-8.609989 145.06234,-8.609989 145.50173,-12.540265 147.654737,-15.947244 149.368356,-18.173689 152.048631,-20.577939 153.981944,-23.025817 154.377395,-24.713568 152.444082,-24.673642 152.09257,-24.233607 151.477425,-24.033086 151.345608,-23.268262 150.950158,-23.066255 150.774402,-22.295873 150.115318,-22.092426 149.719867,-22.21453 149.412295,-21.234769 149.060783,-20.577939 148.050188,-19.794271 147.610799,-19.4217 146.819898,-18.965173 146.424447,-18.131931 146.424447,-17.126792 145.941119,-16.580042 145.545668,-15.608929 145.545668,-14.973088 144.974462,-14.292774 144.491134,-13.909185 143.919928,-14.292774 143.963867,-12.926045 143.656294,-12.325691 143.216905,-11.637889 143.041149,-10.948382 143.656294,-8.609989&rft.coverage=Great Barrier Reef, Australia&rft_rights=&rft_rights=CC BY-NC 4.0: Attribution-Noncommercial 4.0 International http://creativecommons.org/licenses/by-nc/4.0&rft_subject=sea turtle&rft_subject=nutritional status&rft_subject=body fat&rft_subject=adipose tissue&rft_subject=body condition&rft_subject=Bland-Altman&rft.type=dataset&rft.language=English Access the data

Dataset of the manuscript: "Adipose tissue estimation of foraging and nesting green turtles (Chelonia mydas) using bioelectrical impedance analysis.".

Dataset provided in .xlsx, .csv, and .ods formats.

Software/equipment used to create/collect the data: Body impedance measurements were subsequently performed with a handheld bioelectrical impedance spectroscopy (BIS) analyser (SFB7, Impedimed, Brisbane, QLD, Australia) following procedures outlined in Kophamel et al. (2023). The BIS device measured resistance and reactance at 256 logarithmically-spaced frequencies in the range 3-1000 kHz, and device calibration was verified daily during fieldtrips. Ten replicate impedance measurements with an interval of five seconds were recorded to account for intra-animal variability, with each measurement taking 800 ms. The extracted data of interest were resistance at infinite frequency (Rinf, predictor of total body water and fat-free mass), resistance at zero frequency (R0, predictor of extracellular water), intracellular resistance (Ri, an index of intracellular water); and, for comparison with studies using single-frequency BIA (SFBIA) devices, resistance at 50 kHz (R50), reactance at 50 kHz (Xc50) and phase angle at 50 kHz (PhA50).

Software/equipment used to manipulate/analyse the data: Recorded impedance data were analysed using Bioimp software (v5.4.0.3, ImpediMed Ltd, Brisbane, QLD, Australia), that calculates resistance (R, ohm), reactance (Xc, ohm) and phase angle (PhA, arctangent Xc/R, degrees) at each frequency and uses Cole analysis to obtain estimated resistance at infinite frequency (Rinf) and at zero frequency (R0) (Cornish et al. 1993) (for further details please refer to the manufacturer's website: https://www.impedimed.com/).
