This is a demo for exploring and visualizing data for the Ocean Observatories Initiative (OOI) including Quality Assurance of Real-Time Oceanographic Data (QARTOD) flags. OOI uses QARTOD flags in OOI’s online Data Explorer to rapidly identify a time period of interest and then access those data from ERDDAP to plot in our own software environment. Slides are available at: https://tinyurl.com/OOI-QARTOD-demo. This material is based upon work supported by the OOI, which is a major facility fully funded by the National Science Foundation under Cooperative Agreement No. 1743430. Presented by Woods Hole Oceanographic Senior Research Specialist Stace Beaulieu.
