Mysterious algae tumbles into the beach: - I have never seen anything like it

Like the Skagen's old arbejdsskure to the fishermen and sailor in The Red Skurby, the beach is bright red. Heaps of red seaweed towering close to the water's edge.

- There have been a lot more, but part is washed again in the night, and it looks as though that doesn't flush more new up right now. Maybe it is again, if the wind turns. I am a bit excited, explains one of the local fishermen, Kjeld Christian Schrøder Hansen.

Stig Dyrnesli (tv.) and Kjeld Christian Schrøder Hansen both have many guesses as to where the algae can come from, but one can be just as good as the second, as the notes. Photo: René Schütze

He has no idea where it comes from. But one thing he is sure.

- I have never seen such large quantities before. It is violent, but there was so much, but I think not that it is something that is dangerous for us, he says.

the Facts: Seaweed and algae

a generic term for the seagrass and micro-algae.

is the same as the seagrass.

consists of multiple cells, while the micro-algae are single-celled.

So many different species of algae found there.

most algae are harmless, but there are poisonous species.

Stig Dyrnesli, which has one of the pulling by the beach, do not, it is dangerous.

- not at all, for it didn't smell bad, just when it is washed up. It is in fact edible when it is fresh, he strikes fast.


He has lived in utah his whole life, and, like Lisbeth, he is also puzzled about what it is, the sea has washed up.

- never before have We had it this way before. I have dived here for 40 years and I have never seen anything like it, he says.

Stig Dyrnesli can see the special red seaweed on the beach from the window in his sømandsskur, which he shares with two companions. Photo: René Schütze

In skurbyen are tangmassens origin debated, but no one has yet found the answer.

- We talked all about what the hell it was. Some had a suspicion that it came from the ships that are out here. Most clean their ballast water, but there might just be some foreign ships, which do not have sewage treatment plants. But I think now, it is not, therefore, says Stig.

The theory shoots Hanne Kaas, who is a marine biologist by the independent advisory and research organisation DHI, also to the corner.

- I do not think that it comes from ships ' ballast water. It is seaweed, and it is not toxic or anything, " she says, after having seen a news item on TV2 Nord from the beach in Skagen.


She explains that we more often see the green algae and the seaweed, because they grow in the surface of the water.

- The red algae grow basically down, so my guess is that some ocean currents have made, that they have torn itself loose and then flushed into the bay.

Where they have grown, she has not, however, a clear-cut bid on.

- In principle, they can well get far away from. Maybe from the west coast or down from the Netherlands, where they then followed with the ocean current.

She has yet an explanation of why that is happening just now.

- It is the season, when the algae die and are easy to tear loose. At the same time, there is turmoil in the water, and it does so that you see the here opskyld. But nevertheless, I have never seen such a mountain of red algae before, she says.

- The red algae could look like crimson ribbeblad or caragentang. The user you are actually cooking instead of isinglass, says biologist Bjarke Huus Jensen. Photo: René Schütze

At the Danish Nature agency Vendsyssel take tangdyngerne in Skagen in the north peace.

- That looks good enough to be much of it, and it has a fairly strong red color, so it can easily fit, that you have not seen it before on the beach in Skagen, but this is not unusual. On the east coast of Læsø is often similar strips, explains biologist Bjarke Huus Jensen.

He emphasizes that he has not been past the Skagen Beach and found it by myself.
