Changes in fish biomass between 2016 - 2020

Changes in total fish biomass observed on reef transects associated with the 2016 heatwave (left), the 2020 heatwave (middle) and overall (right). The 2016 heatwave-associated fish biomass changes reflect the difference between values observed on surveys before 2016 versus after 2016 but before 2020. The 2020 changes reflect differences in values from after the 2016 event but before the 2020 event, versus after the 2020 event.
