NESP TWQ Round 4 - Project 4.2 - Oceanographic drivers of bleaching in the GBR: from observations to prediction

This project seeks to understand how local, regional and global oceanographic and meteorological processes influence the severity and spatial variability of thermally driven coral bleaching for the Great Barrier Reef (GBR) and Torres Strait.

All available relevant environmental observations of the recent bleaching events will be gathered to be more easily discoverable to researchers and managers via a gateway/summary webpage.

The data will be used to assess how well the eReefs models are modelling the recent warming during bleaching events and then analyse the reasons behind the variations of bleaching response. 3D versions of remotely sensed bleaching products by NOAA and BoM will be produced and a seasonal prediction capability for marine heatwaves will be developed.

A workshop at the ACRS 2019 conference was run on accessing oceananic data for coral reef research. The manuals used in the workshop are now available.

PreviewThe climatology of the GBR temperature loggers is based on the hourly registers from loggers with 10 or more years of data, up to 2012 and for "Slope" and "Flat" locations on the reef.

PreviewThis dataset explores a new approach to predict coral bleaching events. It uses a temperature anomaly map to create a spatially dynamic temperature threshold for the calculation of degree heating weeks (DHW) instead of using a static constant.
