The days are getting darker and colder and Christmas is just around the corner. In Finland and Sweden SEAmBOTH teams are working frenetically to compile and analys data from this year's field surveys in the northern Bothnian Bay. From the snorkel surveys in shallow areas in Sweden we have been going through vast amounts of … Continue reading Underwater in the shallow bays
This Summer the Metsähallitus marine team was working quite close to different kinds of human pressures. We worked most of the time close to the mainland, so we saw a lot more human activities then we normally do, from farther out at sea. In the earlier blogs there has been information about estimating human pressures … Continue reading Field stories: working close to human pressures
The field season of 2018 is coming to an end for SGU and Ocean Surveyor, which in a couple of days will anchor for the winter in the port of Slagsta, in lake Mälaren in the vicinity of Stockholm. The coast of Haparanda in the Bothnian Bay has presented us with many challenges, with its … Continue reading Field season 2018 – SGU
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 of all the challenges that we had to conquer resulting from working in shallow … Continue reading Field stories: It’s not what you know, it’s how shallow you can go
GTK´s Marine Geology unit started SEAmBOTH-field work in early June. First R/V Geomari did acoustic-seismic soundings and then some sampling work in Kemi river estuary. Our smaller vessel Gridi started her work in early August, first in Kemi river estuary and then the Krunnit area. After a long transit from the south, work started from … Continue reading Field stories: Offshore again
10 days ago our research ship Ocean Surveyor left our previous project on a bank in the middle of the Baltic sea where we have been surveying geology and habitats since early summer. After a three-day transit we arrived to the northern most outpost of the Swedish marine waters, Haparanda in the Bothnian Bay. This … Continue reading SGU finally arriving at the scene for our first week of field work!
Rather quite shallow, especially around the archipelago of Haparanda and Torneå. In shallow waters like this, at a maximum depth of around one meter, the perfoliate pondweed (Potamogeton perfoliatus) and pond water-crowfoot (Ranunculus peltatus) reach up to the surface and create patches, sometimes impenetrable. We usually keep a look out for rocks whilst driving the … Continue reading Field stories: The sea is not always deep…
