A Corrigendum on
Seasonal Changes in the Drivers of Water Physico-Chemistry Variability of a Small Freshwater Tidal River
by Indivero, J., Myers-Pigg, A. N., and Ward, N. D. (2021). Front. Mar. Sci. 8:607664. doi: 10.3389/fmars.2021.607644
In the original article, there was a mistake in Figures 3, 4, 5, 6, and 7 as published. The images did not correspond to their captions. Additionally, the description for Figure 3 incorrectly included the sentence “Blue background delineates distinct period of storm-driven parameter behavior (greater variability) over the course of the year” that referred to an older (unpublished) version of the graph. The correct images for Figures 3, 4, 5, 6, and 7 appear below with the correct figure descriptions.
FIGURE 3
Figure 3. Time series of (A) pH, (B) dissolved oxygen (percent saturated), (C) specific conductivity (μS cm−1), (D) temperature (°C), (E) turbidity (FNU), and (F) river stage (m) over the course of the study period, October 16th, 2017 through October 12th, 2018. Blue background delineates distinct period of storm-driven parameter behavior (greater variability) over the course of the year. Measurements were taken every 5 min from October 16th to December 4th, 2017, and every 15 min from December 21st, 2017 to October 12th, 2018. Turbidity data above the detection range (4000 FNU) were removed, as well as turbidity data after June 15th, 2018 due to a sensor maintenance issue.
FIGURE 4
Figure 4. Time series of example summer day (May 1st, 2018) averaged by hour of pH, specific conductivity, dissolved oxygen, turbidity, temperature, and depth. Colors indicate rising tide and falling tide (determined by timing of high and low tide) and day and night (determined by sunrise and sunset time).
FIGURE 5
Figure 5. (Left) Daily average pH in the Union River and in the Hood Canal measured at the Twanoh Buoy by (ORCA-UW, 2018) from October 13th, 2017 to April 9th, 2018. Date is displayed as Month-YY. (Right) Daily average pH in the Union River compared to the Hood Canal (r = 0.47, p < 0.001).
FIGURE 6
Figure 6. Monthly intercycle (i.e., non-tidal) and intracycle (i.e., tidal) variability for pH, turbidity, dissolved oxygen, specific conductivity, and temperature in the Union River shown as relative proportion for each month. The dashed line indicates a relative proportion of 0.50: i.e., intra-and intercycle variability for that month were equal. Intracycle variability >0.5 (above the dashed line) indicates that tidal variability was dominant, whereas intracycle variability <0.5 (below the dashed line) indicates that non-tidal variability was dominant. Intracycle variability is calculated as the monthly average of tidal cycle standard deviations for each parameter. Intercycle variability is calculated as the monthly standard deviation of tidal cycle mean.
FIGURE 7
Figure 7. Examples of hysteresis observed for pH, dissolved oxygen, specific conductivity, and turbidity for two storms on the Union River. Two example storms are shown to demonstrate different types of hysteresis seen during the 2017–2018 study.
