SGU finally arriving at the scene for our first week of field work!

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!

Field stories: The sea is not always deep…

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…

It is therefore … Continue reading Stumbling upon the sheated pondweed

While the days are getting colder and the ice starts covering the waters of Bothnian Bay, we’re looking back at the field surveys of 2017 and reminiscing warm, sunny days out at sea (maybe not all the time). SUP-board and aquascope comes in … Continue reading Flashbacks to the summer and field surveys of 2017
