MARE – Marine Research on
Eutrophication: A Scientific Base for Cost-effective Measures for the
Baltic Sea – is a multidisciplinary research program. The overall
goal of MARE is to develop a decision-support system (DSS) to be used as
a tool for developing and testing cost-effective strategies to reduce
eutrophication in the Baltic.
A user manual of Nest can be downloaded from user_manual-Nest.pdf
The whole DSS is designed as a distributed web system. The client program of the DSS – Nest is an application that integrates different kinds of information into one product. The architecture of the system is described in

Digital Terrain Elevation Data (DTED® Level 0) for the Baltic drainage basin is a product of the National Imagery and Mapping Agency. http://www.nima.mil
ETOPO–5 dataset from the NOAA NGDC is a 5 arc minute resolution map of topography and bathymetry for the entire Earth's surface.
High resolution depth topography of the Baltic Sea is based on the data from the Baltic Sea Research Institute, Warnemunde. http://www.io-warnemuende.de/research/en_iowtopo.html. Contact person: Torsten Seifert (torsten.seifert@io-warnemuende.de)

Hydrographic and chemical data are collected from virtually all data makers around the Baltic Sea and stored in the Baltic Environmental Database, Stockholm University. http://nest.su.se/bed
River loads to the Baltic Sea covering the time period from 1970 to 2000 has been compiled by Miguel Rodriguez Medina (miguel@system.ecology.su.se) at Department of Systems Ecology, Stockholm University. This compilation is based on data set for 1970-90 provided by Per Stålnacke (per.stalnacke@jordforsk.no) from Tema Vatten, Linköping University and recent data from number of sources, see http://nest.su.se/bed/river_inputs.shtml

Atmospheric nitrogen deposition to the Baltic Sea used in the EMEP module originate from the UNECE/EMEP emission database. For information about the modelled data, please go to the EMEP home site.
Module Cost calculation is an interface to a model developed by Ing-Marie Gren (ing-marie.gren@konj.se) now at the National Institute of Economic Research, Box 3116, 10316 Stockholm. For further details, see

Module Marine model is an interface to a model of large-scale nutrient biogeochemical cycles in the Baltic Sea developed by Oleg Savchuk (oleg@mbox.su.se), Department of Systems Ecology, Stockholm University. Currently, the model is set up in a steady state mode. Details are presented in
Oleg Savchuk. Simple As Necessary Long-Term large-Scale simulation model of the nitrogen and phosphorus biogeochemical cycles in the Baltic Sea. Technical report, version 3, March 2006. SANBalTS_QAv3.pdf
Module Watershed model is an interface to data describing Baltic Sea drainage basins characteristics and a model, MCSIM, of nutrient load. Details are presented in

Module Fish model is an interface to modelling results, compiled by Olle Hjerne (olle@ecology.su.se), Department of Systems Ecology, Stockholm University using the fish model developed by Chris Harvey et al. (2003, corresponding author is Sture Hansson, sture.hansson@ecology.su.se), using the Ecopath with Ecosim software (http://www.ecopath.org). It is a food web model of the Baltic Sea proper, with 15 functional groups from phytoplankton to seals. The model was parameterized with the main focus on fish (sprat, herring and cod). The original model has been slightly modified by Olle Hjerne (olle@ecology.su.se). More details are available in the Model_documentation_05_Rev_SH_OH.pdf

Water transparency relationships to nutrient concentrations were estimated at the Department of Systems Ecology, Stockholm University. Details are presented in
