As soon as we put our head under water that … Continue reading Mapping seafloor habitats

Expert work is often lonely - you read reports or scientific papers and write some of your own. Every now and then you get to attend a meeting, sometimes even face-to-face and not only through the Skype. In the field it’s different. We work as a team, and very often as pairs.

In my case, I work as a marine geologist at the Swedish Geological … Continue reading People behind the scenes: Gustav Kågesten, marine geologist, SGU

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
