Nested temporal variability of carbon and environmental parameters at the Pivers Island Coastal Observatory study site.

<p>Plots depict pH_T (<i>in </i><i>situ</i>: A-C), chlorophyll (µg L^-1: A-C), DIC (µM: D-F) and associated physical variables including incoming no-sky solar radiation (W m^-2: A-C), water temperature (°C: D), or tidal height (MLLW, m: E-F). Data are shown depicting the nested sampling design with weekly measurements over the course of the year (A, D), daily measurements over a 3 week period (B, E) and hourly measurements over 3 days (C, F) Gray bars indicate periods of more intense sampling, shown in the panel immediately below. Cyan bars indicate periods influenced by major storm events. For clarity, only the maximum daily W m^-2 is plotted in top row.
