Extended Data Fig. 11: DTS calibration residuals.
From: Calving-driven fjord dynamics resolved by seafloor fibre sensing
Temperature from PT100 sensors subtracted from the calibrated DTS temperature at the corresponding reference. The internal (blue) reference section was not used for calibration. A 24 h oscillation is evident and results from slightly different temperatures at the PT100 sensors and along the fibre in the reference section. In the DTS data that we present, we correct for this artifact. We extract the oscillation in the bay cable section (1,000–1,800 m OD), where we do not expect strong (≳0.2 K) diurnal oscillations, and subtract them across all channels.
