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

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
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
Diving is one of our three main methods for collecting biological data from the Bothnian Bay. The other two are drop-videos and wading. https://videopress.com/v/UbhCWIwI?preloadContent=metadata 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
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
One of the things we do in the SEAmBOTH project is to produce maps which can help us identify valuble areas in the sea. Becuase we know that valuable areas are those that we should not destroy, those we should take extra care of to ensure the sea remains healthy and in good status. Therefore … Continue reading What is valuable nature?
