Figure 1.
Nested temporal variability of carbon and environmental parameters at the Pivers Island Coastal Observatory study site.
Plots depict pHT (in situ: 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.

Non-dimensional analyses of weekly samples (2011) from the Pivers Island Coastal Observatory.
A. Principle component analysis of the observed environmental variables. Cyan oval highlights environmental samples following significant storm events. B. Hierarchical clustering of time-series observations with color coded branches based on the season of sampling (blue=October-March, red= April-October, cyan= post-storm). In both panels sample numbers correspond to the week of sampling.
