As part of the suite of Conductivity, Temperature, Depth (CTD) AI tools being produced by the Office of the Chief Data Steward (OCDS), we are developing a model to assist with identifying and deleting poor-quality scans during the CTD quality control process. Using a combination of a Gaussian Mixture Model (GMM) to cluster CTD scans into groups with similar physical properties and Multi-Layer Perceptrons to classify the scans in each group, we are able to automatically flag the poor-quality scans to be deleted with a high degree of accuracy. Through the deployment of the model as a real-time online endpoint and the support of model communication through a client-side program, we have successfully integrated an experimental model into the client's business process in a field testing environment. The continuation of this line of work will now look to bring the model into a production environment for regular usage in the quality control process.

The quality control process for CTD data is a highly time-intensive task. An oceanographer performs a visual inspection to identify poor-quality scans in each CTD profile using graphical editing software. As the task requires careful inspection and the CTD profiles collected during one year number in the thousands, this work consumes a large amount of time and effort. To ease this burden, we have produced an AI tool that is capable of flagging the poor-quality CTD scans such that these flags can be displayed to the oceanographer within the graphical editing software. This allows for the task to be sped up by providing a quick reference for the areas in the CTD profiles where attention is required. By providing flags for assisted decision-making rather than using the model for fully automated decision-making, we preserve the ability of oceanographer to use their domain expertise to make the best possible decisions. As the model becomes more mature and its performance improves, we may explore options to increase the degree of automation.
