Field stories: The sea is not always deep…

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 boat, here it is rather the vegetation we try to avoid getting too close to.

However much we like the underwater vegetation, there are the moments when the greens are not as appreciated… Regular stops to clean the propeller are frequent….

 

When working in shallow waters our stand up paddle board is  invaluable to  transport us longer distances over the water. Sometimes though when it gets too shallow, it is just easier to skip the board and take a good-old walk instead!

 

And in the end of the day we will have found out that walking – not driving – the boat is by far the best way to get back home.
