Description (status of criteria/indicator) |
Despite a major effort to reduce the Danish input of nutrients to the Danish waters, the marine areas still suffers from inputs of nutrients and organic matter from both local sources and transboundary transport. |
The Nitrogen load has been reduced with approximately 50 % since 1990, but algae blooms, oxygen deficit and low depth limit of seagrass still occurs. Transboundary inputs are high. |
The phosphourous load has been reduced with 66% since 1990, but especially in the coastal areas it needs to be reduced further.Transboundary inputs are high. |
The Direct discharge of organic matter from danish sources has been with more than 50 % since 1990. Transboundary inputs are high. |
During the growing season there can occur high phytoplankton biomasses causing low water transparency in the water column. |
In the autumn areas with oxygen deficit occur due to the degradation of the high phytoplankton biomass settled to the seabed during spring and summer. |

Description |
The Kattegat area and the coastal area along the Danish westcoast is subject to nutrient and organic enrichment. The limiting factor for the production in the area is nitrogen. The Danish parts of the North Sea and Skagerrak are in good status. |
Ind the period 1990 - 2010 the discharge of nitrogen from landbased sources has been reduced with approximately 50 %.Half of the total N-input is from atmospheric deposition and the Danish contribution to the atmospheric deposition is around 16 %. |
The Kattegat area and the coastal area along the Danish westcoast is subject to nutrient and organic enrichment. The Danish parts of the North Sea and Skagerrak are in good status. |
Ind the period 1990 - 2010 the discharge of phosphorous from landbased sources has been reduced with approximately 66 %. |
The Kattegat area and the coastal area along the Danish westcoast is subject to raised levels of phosphorous. The Danish parts of the North Sea and Skagerrak are in good status |
The impact is causing changes in the following: Chlorophyll concentration, water transparency related to suspended algae, pelagic shifts and indirect impacts such as changes in dissolved oxygen levels. |
The impact is causing changes in the following: benthic fauna and flora shifts and organic enrichment and changes in dissolved oxygen levels. |

Description (activities) |
The main contribution of nitrogen to the Sea comes from Agriculture while the main discharge of phosphourous comes from the industry and urban discharges. The main part of the atmosphaeric deposition is from sources outside Denmark. |
