Title:
Atlantic Ocean Acidification Test-Bed -- OA Time-Series, Cheeca Rocks, Florida Reef Tract FY2012
Abstract:
The AOAT project is engaged in monitoring/modeling efforts designed to: a) establish methodologies for monitoring, assessing, and modeling the impacts of Ocean Acidification (OA) on coral reef ecosystems, b) identify critical thresholds, impacts, and trends necessary for developing forecasts, c) characterize the variability in carbonate chemistry in coral reef environments, and d) provide data and information needed to inform ecological impact forecasting. Existing projections of OA on coral reef ecosystems (e.g. Silverman et al., 2009) make a core assumption that secular declines in carbonate mineral saturation state (omega, a key parameter of OA interest) are equivalent to those experienced in the oceanic surface waters. Sustained observations at the AOAT, however, reveal considerable complexity and diverge from neighboring oceanic waters during most periods. Seasonal ranges in omega values exceed those anticipated as a consequence of OA over the next several decades. Complexities within near-reef waters are likely the norm and we seek to better model the primary controls on near-reef carbonate chemistry. The AOAT has served as a critical venue to foster research from other agency and academic partners towards the development of techniques which can be applied to monitor OA within reef environments and quantify the local feedbacks that can alter rates and magnitude.
Supplemental_Information:
Time is GMT; O2 is concentration of dissolved O2 in seawater in micromoles; Salinity is in practical salinity units; temperature is in Celsius; CO2 is reported as mole fraction for atmosphere and seawater -9 in the data set indicates that the parameter is unavailable

Why was the data set created?

OA is expected to reduce the calcification rates of marine organisms, yet we have little understanding of how OA will manifest within dynamic, real-world systems, nor how to accurately measure said manifestation.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: May-2013 (process 1 of 1)
    Data have been manually screened and erroneous values due to instrument malfunction have been noted and/or removed.

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Data has been reviewed and edited in attempt to remove unreliable values.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Time, Sea Temperature at surface, Salinity (1 m), Oxygen (uM),xCO2 (umol/mol) for atmosphere and surface seawater are the only parameters available.

  5. How consistent are the relationships among the observations, including topology?

    none

How can someone get a copy of the data set?
