Om mig

Omnivorous with a broad interdisciplinary scientific profile in aquatic ecology: geochemistry, biogeochemistry, including field studies, different forms of experiments and also certain analytical chemistry issues. These studies extend from pure environmental chemistry to ornithology, carried out in marine and freshwater ecosystems, with focus on the Baltic Sea and its drainage area. Also, research in the Arctic has been conducted.



I am an Associate Professor in Ecology and Senior Lecturer in Marine Ecology, conducting regular teaching, as well as supervision of master students and PhD candidates.

Course leader (and founder) of the advanced undergraduate (master) course in Aquatic Ecology (9 weeks yearly) since 1995.

Recent supervision commissions are one PhD thesis (Nils Ekeroth) officially defended in 2015, and one (Kjell Grip) is planned to be defended during 2016.


My current research is mostly focusing on:

1. Various aspects on production ecology in the Baltic Sea and its catchment area, particularly with respect to eutrophication and remedy actions. For proper understanding, focus is directed to sedimentation and nutrient dynamics in general, and to limiting factors of photoautotrophs in marine versus freshwater environments [e.g., Gunnars et al. 2002, GCA 66: 745-758; Blomqvist et al. 2004, L&O 49: 2236-2241].

2. Efficient remediation of the Baltic is a much wanted concern. A current project ”Permanent inactivation of phosphorus in Baltic sediments” aims to sequester and enhance long-term removal of P by supplying fine particulate (lutite) matter of marl to the sea bottom [Blomqvist & Rydin 2009, Rept 5914 Swedish EPA, Stockholm]. A key problem is to metamorphorize (transform) the marl into an efficient physical phase, possible to supply and get settled on the bottom sediment.

3. Migration and population dynamics of arctic breeding waders across Fennoscandia [e.g., Blomqvist et al. 2002, Oecologia 133: 146-158], and the occurrence of marine seabirds in the Baltic and the North Sea [Peterz & Blomqvist 2010, Ardea 98: 169-178], are exciting topics with broad scientific implications, not least in large-scale environmental monitoring of remote areas.

4. A prerequisite for trustworthy studies are reliable and versatile field techniques. However, most devices used are suffering from major faults and dysfunctions, for instance, when sampling soft sediments [e.g., Blomqvist 1991, MEPS 72: 295-304; Blomqvist et al. 2015, MEPS 538: 13-21]. Improved methods are therefore a most concerned matter for future scientific development in aquatic ecology and associated topics, including global change issues.
