From mid-November 2019 to late March 2020, IMOS ocean gliders spent 85 days at sea in the central and northern Great Barrier Reef (GBR), travelling a total of 1800 km between Cooktown and Townsville. These gliders included routine IMOS deployments in the GBR as well as an additional deployment as part of the IMOS Event Based Sampling sub-Facility.

The ocean gliders made ~20,000 full-depth ocean profiles consisting of 3.5 million individual observations of temperature, salinity, oxygen, underwater light, chlorophyll, backscatter and CDOM. The data were immediately available to researchers as they were collected via near-real-time data delivery and following QA/QC processes the entire dataset is now publicly available via AODN.
