The excel file contains: summary of daily maximum precipitation from global rainfall analysis, monthly change in seagrass indicators (biomass, leaf density etc); water quality data including salinity, temperature and light data. There are also .nc files containing precipitation data from 1979-2019.



Research Activity Title

Population-specific resilience of Halophila ovalis seagrass habitat to unseasonal rainfall, an extreme climate event in estuaries.

Research Activity Description

This research investigates whether unseasonal rainfall events can be considered extreme in estuaries across the globe that represent different climatic settings. Additionally, a case study estuary is selected following an extreme rainfall event in 2017 is selected. Metrics are adapted to characterize aspects of the event using salinity data by adapting an approach applied for marine heatwaves. The resilience of seagrass is also measured prior to and following the event. We found that some seagrass populations were able to recover whilst others did not and this may be attributed to differences in their environmental regime.

Viewing Instructions

Subject to the reader’s preference, the .nc files were viewed using the program software R.

If using R, there are many options online available that provide code to view the files. Below is an excerpt of the code we used for the Swan-Canning estuary ( as an example.
