Atmospheric N transport using The DEHM model
• Calculations of monthly depositions of different N-fractions to 13 areas used in the BALTSEM model with a resolution of 50 km x 50 km (1991-2006)
• The depositions will be available in the NEST system
• Depositions from 10 different sources:

Modelling loads of water and nutrients
• Detailed, dynamic process modelling of retention in surface water.
• Models to calculate loss of nutrients with high resolution.
• Combining detailed production data with a catalog of means to reduce losses of nutrients, inclusive costs
• Scenarios: Status quo vs. Implementation of WFD requirements and climate changes

Maintenance and opdating GIS data Objective: • improve and update the
quality of existing GIS data in the NEST system
• coordinate model interfaces with GIS data
• Construct administrative GIS structures
• Couple models and GIS into a dynamic solution
• collect GIS data from The Baltic Sea Ecoregion
• develop new areas for economic data and presentation of results in NEST
modeldatabase

What exact steps should be taken to aid the implementation?
• Science-based support system• Update the databasis (1997-1993 – now)• Improve models (coast vs. open sea, dynamic
modelling, Danish Straits)• Link models• Develop cost minimization models• Open source philosophy• Data, models and manuals available to the
public

Conclusions
• The NEST philosophy will establish a science-based decision support system to improve the basis for political decisions
• NEST will link ecological and economic models
• Continued work in NEST will improve research, monitoring and management in the Baltic Sea Ecoregion
• All NEST work is done with end-users
