Issue: Contributions and pressures between the coasts and oceans and inland water - Effect of changes in coasts and oceans on inland waters
This is an issue under the Coasts and oceans theme of the Data Reporting System.
Why we need to know about this issue
The ocean contributes saline waters, marine species and climate moderation to coastal habitats. It can place pressure on inland waters and interface species during sea surge events or as a result of influx to groundwater, or in the event of rising sea levels or changing currents.
Indicators
- CO-01 Trends in selected groups of coastal and marine species and habitats
Interface species can be affected by changes to inland waters arriving from the ocean, for example during sea surges, seawater intrusion into groundwater or rises in sea level. - CO-03 Sea level
Sea level change has potential impacts on the ecosystems at the interface of coastal and inland waters, as freshwater or brackish systems become more saline. - CO-46 Comparative water quality of coastal lakes and lagoons (water quality gradient from north to south)
Coastal lakes and lagoons are at the interface of coastal and inland waters and their condition could be indicative of changes either from the oceans or from inland waters. - CO-68 Examples of sea surge and seawater intrusion events
Influx of sea water into groundwater and surface freshwater systems can occur naturally as a result of sea storms or as a result of sea level change which may be associated with anthropogenic climate change. It can place significant pressure on resident species and ecosystems. No indicator has been developed for measuring or assessing the extent of this pressure or its actual impact on aquatic organisms. Some examples or case studies may be possible.
