MHWs can have a devastating impact on marine ecosystems, with a strong El Nino event currently underway in Australia. Forecasts by CSIRO indicate sustained increases in water temperatures down the east coast of Tasmania for this summer, with potential to significantly impact on fisheries, aquaculture, and marine habitat. Improved forecasting by CSIRO has provided industry and government with the opportunity to be better prepared, with the monitoring of ambient temperature is a key component of this. While sea surface temperature (SST) models from BOM and NOAA can provide information regarding broadscale patterns, missing is fine-scale, near-coastal and below surface information that is highly relevant to fisheries, aquaculture and marine coastal environments. While some industries monitor temperature as part of operations (e.g. salmon, oyster aquaculture), other industries are missing any fine scale information that may be of relevance to their operations. This project has two main components:
1. To support and integrate existing infrastructure that collects temperature data across the summer along the east-coast of Tasmania. This includes data collected by IMAS research projects, both long and short-term, where QAQC on data is high and there is confidence the data is robust both spatially and temporally. This data will be used to understand broadscale trends at depth across a predicted MHW event.
2. To implement a pilot industry deployment of temperature loggers across the seafood supply chain. The two industries targeted for pilot deployments will be the octopus fishery and the rock lobster fishery, with loggers mounted on pots and in holding wells of boats. This pilot program will aim to develop industry-relevant temperature monitoring methods for industry for future MHW events. Data from objective one will be used to ground-truth results and validate methods used in the pilot program.
Overall, the data will be used by government and industry to aid in the fisheries management in MHW conditions into the future.


1. To develop a framework for collection of robust temperature data from depth along the east coast of Tasmania
2. To validate the approach of rapid industry deployment of loggers to monitor temperature in MHW conditions for providing fine-scale variation in temperature.
3. Use the combined data to better understand how temperature data can inform fisheries management for future MHW events
