10 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark Atmospheric N-transport using The DEHM model The Danish Eulerian Hemispheric Model (DEHM) is state-of- the-art atmospheric modelling and is applied in NOVANA, AMAP, and research projects

11 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark 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 ( ) The depositions will be available in the NEST system Depositions from 10 different sources:

13 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark Drainage basin modelling Improve existing model (CSIM), through a dynamic calculation of nutrient retention in surface water (wetlands, rivers and lakes).

14 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark 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

16 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark BALTSEM model struktur 13 sub-basins: Northern Kattegat, Central Kattegat, southern Kattegat, Samsø Belt, Fehman Belt, Øresund, Arkona Basin, Bornholm Basin, Baltic Proper, Gulf of Riga, Gulf of Finland, Bothnian Sea, Bothnian bay. Coupling Physical and biogeochemical Process: 17 state variables (14 in Pelagic layer and 3 in sediment): nutrients (7), phytoplankton (3), zooplankton (1), detritus (3), oxygen, salinity and temperature Forcing functions: Temperature, wind, current velocities, solar radiation, nutrients and etc. Spatiotemporal dynamic: seasonal (monthly), vertical and horizontal distribution of species

26 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark 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 model database

27 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark What exact steps should be taken to aid the implementation? Science-based support system Update the databasis ( – 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

28 Baltic Sea Round table seminar – Copenhagen 17. March 2008 Baltic Nest Institute, National Environmental Research Institute, Aarhus University, Denmark 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
