The traditional archive pipeline involves a desktop application to package acoustic datasets onto hard drives that are then mailed to the NOAA office in Boulder. This process has become less viable with the exponential growth of ocean acoustic data volumes and as NOAA data providers have recently accelerated moving their data stores to cloud environments. In order to leverage this move to the cloud, the team has built a cloud-based application called Tugboat to enable archival through direct interaction with data provider cloud environments. In addition to offering an alternative to shipping hard drives, Tugboat allows data providers immediate access to updates in the team’s controlled set of metadata and shortens the timeline to receive feedback on their data submissions. As the application matures, Tugboat’s structure will allow for a more accessible user interface, a more scalable architecture depending on organizational needs, and the ability to handle a larger variety of data types.
