Secchi depth measurements from the PICO time-series station. Dataset Description: <p>Secchi depth measurements from the Pivers Island Coastal Observatory (PICO) from 2010 to 2012.</p>
<p>Note: Secchi depth was not measured at all time points, thus, some dates have no data ('nd') in the 'secchi_depth' column.</p> Methods and Sampling: <p>Secchi depth was measured in duplicate using a 20 cm disk with four alternating white and black quadrants by lowering the disk until no longer visible and recording the depth.</p>

Carbon dioxide is rising at ~3% per year in the atmosphere and oceans leading to increases in dissolved inorganic carbon and a reduction in pH. This trend is expected to continue for the foreseeable future and ocean pH is predicted to decrease substantially making the ocean more acidic, potentially affecting the marine ecosystem. However, coastal estuaries are highly dynamic systems that often experience dramatic changes in environmental variables over short periods of times. In this study, the investigators are measuring key variables of the marine carbon system along with other potential forcing variables and characteristics of the ecosystem that may be affected by these pH changes. The goal of this project is to determine the time-scales and magnitude of natural variability that will be superimposed on any long term trends in ocean chemistry.</p>
