Issue: Contributions and pressures between the coasts and oceans and inland water - Effect of changes in inland waters on the coasts and oceans
This is an issue under the Coasts and oceans theme of the Data Reporting System.
Why we need to know about this issue
Inland waters contribute freshwater and freshwater species to habitat for coastal species and can place pressure on them by carrying excess freshwater, nutrients, sediments, pollutants or excessively warm or cool water to coastal waters.
Indicators
- CO-01 Trends in selected groups of coastal and marine species and habitats Changes to inland waters, such as nutrient or sediment loads, can place pressure on coastal and estuarine waters.
- CO-28 Quantity of discharges of different substances from humans activities to coastal and marine water
Pollutants that potentially impact on marine biodiversity and marine water quality can enter coastal and marine waters via outfalls of inland waters. Substances vary enormously in terms of what quantities are dangerous to human health and the environment. Therefore a breakdown, as far as possible, of quantities of all substances discharged from coastal facilities either directly into coastal waters, or into coastal freshwater systems, is required to give an indication of the scale of this pressure. - CO-29 Change in area of coastal potential acid sulphate soils under development for human use
Acid sulphate soils, released from adjacent land by development can reach coastal and estuarine waters via river outflows. - 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 - IW-12 Catchment nitrogen and phosphorus load
Nitrogen and phosphorus loads carried by inland waters can end up in coastal waters where in can place pressure aquatic and estuarine species as well as on other coastal species that rely on the water source. Quantities of nitrogen and phosphorus concentrating in surface water catchments are a direct measure of this pressure. - IW-13 Catchment sediment load
Sediment loads carried by inland waters can end up in coastal waters where sediments can place pressure aquatic and estuarine species as well as on other coastal species that rely on the water source. Quantities of sediment in surface water catchments are a direct measure of this pressure.
