The northern Bothnian Bay is a unique area in the most northern part of the Baltic Sea. It is shared between Sweden in the west and Finland in the east. What hides beneath its surface is today still largely unknow. To uphold an effective and sustainable management of the area and its ecosystem services, improved knowledge of the marine environment as well as management collaborations across the border is crucial.

The SEAmBOTH project is a three years project partly funded by Interreg Nord. The main goal of the project is to help ensure the conservation of the biological diversity, habitats, ecosystems and the ecosystem services existing within the Bothnian Bay.

The sea floor will be mapped by high-tech sonars and multibeam equipment, the vegetation will be investigated by scuba divers and in the very shallow areas laser scanning planes will fly across to measure the depths. With the help of the collected and existing data, maps of the underwater landscape are to be produced. The maps will in turn serve as support for decision-makers, urban planners, environmental inspectors etc., as well as providing valuable information for the public.

Field stories: It’s not what you know, it’s how shallow you can go

Latvasilmu osk Ympäristöpalvelut worked this summer for Lapland and North Ostrobothnia ELY centres carrying out SEAmBOTH field surveys at Natura2000-reserves in Bothnian Bay area. I will remember this years field surveys in Bothnian Bay not from the endless heatwave but because all the challenges that we had to conquer resulting from working in shallow areas. … Continue reading Field stories: It’s not what you know, it’s how shallow you can go

SEAmBOTH in SDBday -satellite derived bathymetry technology and user forum

Even with ‘traditional’ mapping methods maintaining a crucial role in biological conservation, emerging new technologies enable us to work to a larger degree behind a computer screen. The increased quality and availability of satellite images is something that we are interested to utilize in SEAmBOTH. The plus side for satellite images is that they are … Continue reading SEAmBOTH in SDBday -satellite derived bathymetry technology and user forum
