BALTIC GAS is a BONUS project addressing climate change.

BALTIC GAS is a research project exploring emissions of the greenhouse gas methane from the seabed of the Baltic Sea into the overlying water column and further into the atmosphere.

BALTIC GAS applies seismo-acoustic and geochemical approaches to map shallow gas in Baltic Sea sediments and to analyze how climate change and eutrophication impact methane gas production, gas accumulation and methane flux.



BALTIC GAS was funded by BONUS The Baltic Organisations Network for funding Science EEIG.

The project period was 01.01.2009-31.12.2011.
