Significant risk of blue-green algae blooms in summer across Finnish sea areas – warm and sunny summer may dramatically increase occurrence of blooms

Press release, June 6, 2019, Finnish Environment Institute
The risk of significant and widespread blue-green algae blooms in Finnish sea areas matches that of previous years, since the nutrient situation has remained largely the same. This summer brings with it a substantial risk of blue-green algae formations in the Gulf of Finland, the northern part of the Baltic Proper and most of the Finnish Archipelago Sea. The risk is moderate in the south east Bothnian Sea. In other parts of the Bothnian Sea and the Bay of Bothnia, the risk is low. The weather conditions during the summer will determine whether or not the risk is realised. Read more about the risk of blue-green algae blooms in summer across Finnish sea areas

Algal bloom monitoring June 20, 2019: Cyanobacteria occurrence has increased in some lakes, in the Finnish sea areas the cyanobacteria situation is typical for the Midsummer week

Due to warm weather the occurrence of cyanobacteria has increased in lakes, but the algal situation is still rather typical for the period. Both in the coastal and open sea areas of the Baltic Sea only single surface blooms of cyanobacteria have been observed. Pollen of pine can still form surface water accumulations in the central and northern Finland that may resemble cyanobacteria.

Monitoring and assessment of environmental impacts of chemical spills in the Baltic Sea

SYKEreport23_2018_cover 125px

This publication resulting from the project is intended to guide authorities responsible for post-spill environmental monitoring and assessment, and to help them to understand how complex issues they might be dealing with due to the wide range of chemicals currently transported. The main goal of the publication is to create better preparedness for establishing an effective post-spill monitoring programme especially in the Baltic Sea, area and it is primarily targeted at decision-makers responsible for the planning and implementation of environmental monitoring after a sudden chemical spill at sea.
