ABOUT THE PROJECT

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.

FUNDING
