Baltic Sea monitoring cruises in August 2021: Signs of recovery in the Gulf of Finland, situation in the Bothnian Sea cause for concern (syke.fi)

Press release, September 24th, 2021 Finnish Environment Institute
Monitoring cruises show that the Gulf of Finland has recovered from the deterioration caused indirectly by salt pulses in the Baltic Sea in the mid-2010s. Weather-regulated flows between the Gulf of Finland and the main basin of the Baltic Sea cause fluctuations in the state of the Gulf, which makes it difficult to discern the impact of emission reductions. In deep-water regions of the Bothnian Sea, oxygen levels appear to continue to deteriorate.
