Eastern Tasmania Marine Heatwave Atlas

We have used a quantitative definition of marine heatwaves to detect all events which have occurred in 12 regions across the continental shelf off eastern Tasmania over 1993-2015. For each event in each region this atlas includes information on (i) event properties including intensity, duration and depth, (ii) maps of regional ocean circulation and ocean temperature during the event, and (iii) maps of regional atmospheric conditions during the event (air temperature and surface wind). Also provided are summary statistics including the typical conditions which give rise to marine heatwaves in each region and annual time series demonstrating interannual variability and long term trends in marine heatwave properties. Provided is a comprehensive document presenting the atlas and a set of CSV files containing the underlying data.

Statement: Detected marine heatwaves are based on (i) sea surface temperature output from a regional ocean model and (ii) the marine heatwave detection algorithm of Hobday et al. (Prog. Ocean., 2016). Please see "Eastern Tasmania Marine Heatwave Atlas" document, provided as part of the dataset, for details.
