Temperature loggers have been deployed at a range of sites statewide in waters ranging between 6 and 22m depth. From 2012, 29 sites around Tasmania are being monitored. This record shows data collected from 2004 up to March 2025. Data is still being collected (July 2025) and will be added to this collection as it becomes available.

Sustainable finfish aquaculture is dependent on a benthic environment that can assimilate and process farm particulate wastes. In Macquarie Harbour, bottom and mid water Dissolved Oxygen levels have reached very low levels, which is associated with an increase in the presence of bacterial mats and a significant decline in the abundance and diversity of benthic fauna. Dissolved Oxygen levels are a major determinant of the response of benthic communities in the harbour over timescales of months to years. This dataset consist of dissolved oxygen (DO) and temperature data collected using HOBO Dissolved Oxygen loggers (U26-001) deployed at two locations in Macquarie Harbour, Tasmania under FRDC project 2016-067.

Dissolved Oxygen levels are a major determinant of the response of benthic communities in the harbour over timescales of months to years. This dataset consists of data collected by the real-time dissolved oxygen (DO) monitoring system deployed at three locations in Macquarie Harbour, Tasmania. Loggers were originally established under the Sense-T program, continued under FRDC project 2016-067, and deployed and maintained by IMAS. The system consists of 3 strings of acoustically telemetered, optical fluorescence DO, temperature and depth sensors (VEMCO, Bedford, Canada) which measure DO (% saturation) and temperature (°C) across a depth gradient. Data collected from 01-01-2017 to 19-04-2017 consists of data was collected using the first generation of sensors, while data subsequent to 03-06-2017 was collected using a new generation of tags which contain a tilt instead of a depth sensor.
