What are my data retrieval options with Origin?

With an integrated acoustic modem as standard and the option for Edge data processing functionality, Origin ADCPs have more data retrieval options than standard seabed ADCPs.

As with all standard standalone seabed ADCPs the first data retrieval option for Origin ADCPs is download after device recovery. The Origin Portal Web UI comes with an easy interface for downloading the three core Origin data formats. This of course does have some limitations, namely that data cannot be inspected, and validity confirmed until after the ADCP has been retrieved from the water, risking compromised or even lost data.

Alternatively, with an acoustic modem integrated as standard, data can be offloaded in near real-time when using an accompanying topside modem together with the Origin Topside software. Limited acoustic bandwidth will generally prohibit substantial/full data transfer using this approach, but it is a good option if you are only interested in snippets of information, e.g. individual PD0 records to confirm the ADCP is capturing good quality data.

To maximise the performance of Origin’s acoustic modem in a data retrieval capacity, you can upgrade your Origin ADCP to have Edge data processing functionality. Edge will permit you to upload a data processing app to your Origin ADCP that will not only customise, but also optimise the data the ADCP produces for your particular application. An Edge app can be uploaded to your Origin device, and resulting data packets or files exported in full over the acoustic modem, supporting:

1. Near real-time data retrieval and monitoring.
2. Post-capture acoustic data harvesting using a USV or buoy.

Both of these options for retrieving relevant data without recovering your Origin ADCP offer benefits. For instance near real-time data offload can support time-critical decision making. Meanwhile, data harvest without the need for an expensive and carbon intensive crewed vessel presents the opportunity for reduced project costs and safety risk.
