Bioavailability of riverine dissolved organic matter in three Baltic Sea estuaries and the effect of catchment land use
- E. Asmala, R. Autio, H. Kaartokallio, Leena Pitkänen, C. Stedmon, D. N. Thomas
- Environmental Science
- 5 November 2013
The microbial degradation of dissolved organic carbon and nitrogen (DOC, DON) was studied in three Finnish boreal estuaries with contrasting land use patterns (Kiiminkijoki – natural forest and… Expand
Qualitative changes of riverine dissolved organic matter at low salinities due to flocculation
- Eero Asmala, D. Bowers, R. Autio, H. Kaartokallio, D. Thomas
- Chemistry, Geology
- 1 October 2014
The flocculation of dissolved organic matter (DOM) was studied along transects through three boreal estuaries. Besides the bulk concentration parameters, a suite of DOM quality parameters were… Expand

Abstract
The bioavailability of predegraded dissolved organic matter (DOM) from a humic-rich, boreal river to estuarine bacteria from the Baltic Sea was studied in 39-day bioassays. The river waters… Expand
Survival and photosynthetic activity of different Dinophysis acuminata populations in the northern Baltic Sea

Dissolved extracellular polymeric substances (dEPS) dynamics and bacterial growth during sea ice formation in an ice tank study
- S. Aslam, G. Underwood, +6 authors D. Thomas
- Biology
- Polar Biology
- 1 May 2012
Extracellular polymeric substances (EPS) are known to help microorganisms to survive under extreme conditions in sea ice. High concentrations of EPS are reported in sea ice from both poles; however,… Expand
Bioavailability and radiocarbon age of fluvial dissolved organic matter (DOM) from a northern peatland-dominated catchment: effect of land-use change

- Environmental Science
- Aquatic Sciences
- 5 February 2014
The radiocarbon age and biodegradability of dissolved organic matter (DOM) from a northern peat-dominated river system was studied and the effects of land-use were compared. Samples were obtained… Expand
