Mapping seafloor habitats

Air versus water On land we are used to observing the landscape and the animals living there in high definition from even great distances. On a good day we can observe objects several kilometres away and from space the entire planet Earth is observed daily! As soon as we put our head under water that … Continue reading Mapping seafloor habitats

Stories from the depths – A Brief Guide to reading sediment archives

Humans have affected their environment for a long time. The ancient people respected the Earth.  However, they already had an impact on the environment and its state. Over the past decades (and even longer) increased anthropogenic activities have altered both marine and terrestrial environments worldwide. Nowadays it is difficult to find a place on Earth where … Continue reading Stories from the depths – A Brief Guide to reading sediment archives

How we do it: Species identification

No matter how carefully you look, many of the aquatic flora species can’t be identified by naked eyes only. Some of the specific identification characteristics have to be looked at with a microscope. If you want to identify for example a water moss Oxyrrhyncium speciosum, you have to look at the edges of the leaves … Continue reading How we do it: Species identification

How we do it: diving

Diving is one of our three main methods for collecting biological data from the Bothnian Bay. The other two are drop-videos and wading. See how we do it! Photos & videos by Metsähallitus. Editing by Suvi Saarnio with FilmoraGO. When we want species data from deeper than 1 meter we do a 100 m … Continue reading How we do it: diving

Modelling anthropogenic pressures

Human impact modelling typically seeks to assess how strong the cumulative impact (Fig. 1.) of anthropogenic ecological stressors is on the ecosystem, i.e. where nature is experiencing stress due to human activities. Impact modelling might in some cases assess the impact of only one specific stressor or activity; in other cases the ecosystem and its … Continue reading Modelling anthropogenic pressures

The sea is the same but the legal framework looks different in Sweden and Finland. One thing … Continue reading One Bothnian Bay, and a sea of laws regulating it…

Empowering the stakeholders

What do you get when you give paints, sticks and canvases to a bunch of SEAmBOTH stakeholders and tell them to drip, drop, slam, splatter and splurge us a better and a healthier Bothnian Bay? You get a triptyck of three individual, yet still connected paintings with beautifully balanced colors and patterns, that look like … Continue reading Empowering the stakeholders
