Detecting marine heatwaves (MHWs) by using R-programming
summary
Demonstrates an R workflow that detects marine heatwaves from satellite sea surface temperature, recommending 30 years of SST as the baseline and computing standard metrics: duration, mean intensity, max intensity and cumulative intensity. Uses R packages (heatwaveR and related south African tools) and the ts2climatology step to build seasonal thresholds, then the detect function to output a table of discrete events and the event_line plot that highlights the most intense episodes in bright color.
