    Case study: AQUAlogger 530

    Aquatec was required to design and manufacture a new temperature and depth logger for use on commercial fishing vessels. Near-real time data transfer, autonomy and robust design were all key requirements.

    Background

    Long term seabed temperature records in Northeast US coastal waters have traditionally been gathered by casts from research vessels costing up to US$10-20,000 per day. Although this has yielded almost a century of observations, temporal resolution is poor, with measurements only taken a few times a year. From 2001, temperature and depth loggers were attached to some of the millions of lobster traps deployed by fishermen in the region. This increased the spatial and temporal resolution of temperature measurements, but data recovery was lengthy and delayed. A new temperature and depth recorder was commissioned to deliver data to fishermen immediately as the fishing gear surfaced, allowing near real time data transfer to NOAA – the AQUAlogger 530WTD.

    Instrument

    Aqualogger530The AQUAlogger 530 is a standalone temperature and depth logger. The innovative design includes the ability to store data and display graphs automatically via wireless technology, negating the need for a cabled connection or manual interaction.

    The system consists of a data logger and a reader unit. The logger can be triggered to start and stop collecting data at set depths or times. When retrieved from the water, the logger will automatically transmit the collected data to the reader wirelessly, provided there is line of sight and the reader is less than 100m away. The data will then be processed and a graph presented on the connected computer. The process from the start of data transfer to presentation of the graph takes minutes.

    As the instrument was designed for use of commercial vessels, it is durable and has been shock tested to US standards, It can be attached to lobster pots, nets and other equipment. Providing there is line of sight with the reader, the logger may not need to be detached to download the data.
