An examination of the Sf/So salinity ratio parameter identifies five major types of coastal environment around Australia, including runoff-dominated, seawater-dominated, and evaporation-dominated systems. The dataset, from the Australian Ocean Data Network, uses a general equation of salt and water mass balances to estimate freshwater residence time, a proxy for dissolved anthropogenic input. The inverse of residence time is presented as an important parameter for evaluating coastal water quality.
Use Cases
- Classifying coastal environment types based on the Sf/So salinity ratio parameter described.
- Modeling freshwater residence time as a proxy for anthropogenic input flushing using the described mass balance equation.
- Analyzing geographic and temporal variation in climate forcing factors like seasonal rainfall and evaporation described in the overview.
- Estimating quantities of dissolved anthropogenic inputs flushed to the sea based on the inverse residence time parameter mentioned.
Strengths
- Analysis is grounded in a quantitative parameter (Sf/So salinity ratio) and a general mass balance equation.
- Covers five distinct coastal environment types found across the diverse Australian coastline.
