  :description = "Estimate of exposure to fresh water over the period (month) in PSU days. Fresh Water Exposure is calculated as the sum of the daily average salinity (from eReefs AIMS-CSIRO GBR4 Hydrodynamic v2 daily aggregation) below an exposure threshold. Salinity levels above the threshold don\'t contribute at all to the exposure. Thresholds of 26 and 28 PSU were chosen as different species have different tolerances to freshwater exposure, and the most appropriate level is not currently known. This product is calculated only from January to April each year.";
