Macquarie Harbour Dissolved Oxygen and Temperature Sensor Data (2017-2018)

Acoustic telemetry sensors at three locations in Macquarie Harbour, Tasmania, collected real-time dissolved oxygen and temperature data across a depth gradient. Data from January to April 2017 was collected using a first generation of sensors, while data from June 2017 onward used a new generation of tags. This monitoring was established under the Sense-T program and continued by the FRDC project 2016-067, with deployment and maintenance by IMAS.

Use Cases

• Modeling the relationship between dissolved oxygen levels and benthic community health based on the described environmental impact.
• Analyzing seasonal or event-driven changes in water column stratification using the time-series temperature and oxygen data.
• Assessing the performance and data continuity of different sensor generations (first-gen vs. new-gen tags with tilt sensors) mentioned in the description.
• Investigating the spatial variability of hypoxic conditions across the three monitoring locations in the harbor.

Strengths

• Data spans a defined period from 01-01-2017 to 19-04-2017 for first-gen sensors and from 03-06-2017 onward for new-gen sensors.
• Includes measurements of dissolved oxygen (% saturation), temperature (°C), and depth/tilt from sensors deployed at three distinct locations.
• Collected via a real-time monitoring system using acoustically telemetered optical fluorescence sensors.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• A gap in data collection exists between April and June 2017 during the sensor generation transition.
