Zonation is a quantitative decision support tool for spatial conservation planning, developed for solving various problems around spatial management and resource allocation. Zonation was developed in CBIG – Conservation Biology Informatics Group in the department of Biosciences of the University of Helsinki. The team was led by the professor Atte Moilanen who is currently part … Continue reading ZONATION – PLANNERS´ LITTLE HELPER
The deep sea floors are in constant darkness which means no plants can grow there. But that doesn't mean it's a place empty of life. During the autumn of 2018 SGU (the Geological Survey of Sweden) and partner in the SEAmBTOH project, conducted a survey cruise in the archipelago of Haparanda to map the depths … Continue reading Who lives at the bottom of the sea?
When thinking about the sea one probably first thinks about the sound of waves and after that, the calls of seabirds. Birds are a large part of the nature at sea, but seldom a thought is given to how they are a part of the underwater ecology. So, let’s give some thought to how birds … Continue reading Seabirds – a part of the sea
If you ever stand on a shallow sand deposit and try to determine, whether it’s a sandbank or not, you’re not the only one wondering about it. The EU habitats directive tells us that the Natura 2000 habitat 1110 sandbank is predominantly shallower than 20 m and is always covered by water, and it may … Continue reading Unique habitats: Sandbanks
The nature in the northern Bothnian Bay in the SEAmBOTH area is in many ways similar on the Swedish and on the Finnish side. Sure, the Finnish side is more flat and the shores do not slope as fast as on the Swedish side, but both have large river estuaries, many lagoons and bays, with … Continue reading We have it, you don’t
The northern Bothnian Bay is shared by Finland and Sweden, and in many ways the sea is the same. In other ways, differences occur in underwater nature between both sides of the border, although this border only is a human concept and does not affect marine life. One thing that has puzzled our colleagues on … Continue reading Special species: Braun’s stonewort (Chara braunii)
What does the northern Bothnian Bay have in common with for example the Sulu-Sulawesi Marine Ecoregion on the Indonesian archipelago? Not the corals, sharks or sea turtles but well enough the identification as EBSA areas (Ecologically or Biologically Significant Marine Areas). Or as stated on the EBSA website "special places in the world's oceans" (Photo … Continue reading Identified as a significant marine area by UN convention
