There are three major work tasks in the program:

1) physico-chemical factors in inlet and outlet water, executed by Jarðvísindastofnun. 
2) biological and physico– chemical factors in the pelagic habitat, executed by Náttúrufræðistofa Kópavogs. 
3) fish populations, executed by Institute of Freshwater Fisheries (Veiðimálastofnun).

Reports on the findings can be downloaded in Icelandic with English abstract.
