ÖRESUND THE STORY

Writing Öresund's history is not that easy. But we start with 1932, which was a milestone in Öresund's health. Historically, many interesting things happened before this year but we can let someone else write about it.
I choose to mention the posts that are important to the marine underwater environment that I know, please update me if something is missing or wrong.


In 1932, it was decided that you should stop trawling in the Sound and it is still prohibited. We sometimes read about trawlers as thieffish in northern Öresund. This decision was because of the concern that the slow trawls would interfere with the increasing boat traffic in the area. This has meant that we have retained most of our botany fauna when the trawls do not scratch the bottom.
Below we can see a movie when Greenpeace reveals a trawler from Gilleleje as a thief in the Northern Sound.




Then the 50's came and industrialism increased sharply in the area and the factories began to produce more and more. The consequences became more industrial waste in the water. This together with us as a inhabitant around Öresund also wasted and consumed more in general.
During this time, Öresund was an eldorado in sport fishing when this great tuna fished on an annual visit. In the mid-60's, the last time we could see this rescue to Tuna in Öresund. Below a movie from a bygone tuna fishing.




2016 and 2017, it has been observed that single individuals of Tuna fish have begun returning to Öresund. 2017 was the first time you could catch these giants on film in the Sound.
In 1964 the film came seaward. See the wonderful short version of the movie below.



After you watch this movie, you understand what would happen to our water soon.
In the early 1980s, it was quite possible to say in Öresund and we began to expect that
Öresund was dead and a sea without rescue.
For
several years, for example, released 850,000 tonnes of gypsum per year in the belief that it would only be dissolved in the water and disappear, outside of Landskrona and Helsingborg, these gypsumbergs can still be found today without marine life with the high underwater chimneys left. Outside of Landskrona, the plaster berth covers an area of ​​two football plans and sampling has shown that it is thicker than four meters.
Kjell Andersson, who started diving in 1970, was one of the divers during this time who saw this himself when he was under the surface. The attempt to get financial resources to make a film about this so the public and politicians should understand were started. Nix was the answer no one was interested in this that happened below the surface. Many large companies rated this as pure lies and that they followed the rules that existed.

Kjell did not give up and finance this film himself, along with some other enthusiasts, with Michael Palmgren who was a pioneer in underwater filming as a major international film company then his technicians copied. Kjell and Michael created what we call today the CAMP method of transectors that could be filmed between so everyone saw that it was the same place the movies came from. This technology is today used to be "KA" for Kjell Andersson worldwide
"MP" for Michael Palmgren.

The film was 8 min long was shown on SVT 1988 4 weeks before the election and it became a folk storm. 10,000 people trained in Sweden's largest environmental demonstration through Helsingborg. 1988 was characterized by a lot of environmental issues such as algae bloom and sprouts. For the first time, the Environment Party took place in our parliament on this first environmental choice.

Normally, such news would only be forgotten in a few weeks.But Helsingborgs Dagblad decided for an article series that started on November 3, 1987 in its magazine, which later became a book called the Battle of a pure Öresund in 1989.

 

This was the start of the Öresund Foundation https://www.oresundsfonden.se/, which was started on 4 November 1988 by the various people involved, whose purpose was to improve the marine life of Öresund. It was filmed, Photographed, Tunnel samples, Water samples, Made suggestions and, above all, the industry was pushed to improve.
Now you also found all the problems with Sandsugninger that you have been implementing since the 50's. We in Helsingborg remember all the sighs on the Disk or outside Lomma tex. Sandsugning holes do not get any natural water flow, and then fill algae that die and start production of hydrogen sulphide and then nothing can live here when no new acid is added.

 

Another nice film about Öresund and Skälderviken is here. This movie is 40 min tall and was made in 1990. Click on the link below.

Today we have sanding holes that were made in 1950 and still completely without vigor in the Sound. On the Swedish side we have forbidden suction from the bottom of the Sound, but on the Danish side it is still allowed and performed in a few different places. "Strongly, their exports of sand to Skåne have increased". But it is fought with nails and claws that in Denmark's many organizations who want to stop the extraction of raw materials from unique Öresund.
But now back to the industry. Slowly, better and better some of the heavy industries began to move or reduce their production. The comunies began since the 1990s to clean our wastewater a little better, and Copenhagen followed these trails and after some years they also had control over their wastewater. Slowly, life begins to wake up again in the Sound.
1990 was the launcher for the Sea Resource Organization, which is part of Lund University, which wants to show and document our marine environment for the island of Öresund. As well as helping municipalities to focus where needed.

Today, 2017, the Ocean Travel is still active and carries out important missions to municipalities around our coast line. And together with SCSC they are two who are fighting for our Öresund.
Local parts such as Malmö have invested heavily on marine issues with a marine knowledge center at the head of which Michael Palmgren has its fixed point in marine care.
Then the decision was made to build a bridge across the Sound between Malmö and Copenhagen. The concern was that this would create a collapse of the entire Öreund marine environment and samples were picked up to check how it looks before and after the building. Öresundsbro built together with Lund University and Kjell and Michael, who bogged each other over the bottom of the boat and film camera in their hands back and forth to document the underwater environment between Copenhagen and Malmö. This area where the bridge was to be built is Europe's largest, united blue-blue mussel bank of 34 Km2.



The building went forward and consideration for the mussel banks and the belts was taken as well as could be possible. A few years ago, it is seen that the blue mussel banks have grown in volume when the mussels are now also on the bushels.
Now it works so that a 50 mm blue mussel can filter 5 liters of water per hour. So our water began to get clearer and clearer and the light began to get further into the depths.
The algae welcomes in this bright environment and began to expand from being only at a maximum of 4 meters deep to today 10 meters deep. Even eel grass purifies our water and enriches it with oxygen. Ålgräs produces 6 x more oxygen than a rainforest with the same surface. Today, eelgrass beds are counted as the most valuable ecosystems on earth. Now our fish start to grow and grow in larger quantities. These small fishes will be nice food for larger fish and now Öresund will flourish seriously and the quantities of cod picked up by anglers will hit new records. As we mentioned earlier, the Tuna has come back. Probably the increase in fish is one of the reasons for this.
Even in early 2018, they are happy surprises. Large scallop, Latin name Pecten maximus. Found for the first time in Öresund by a Danish fisherman who got this in his yarn. Japanese giant cheese has also been found in both Helsingør and Helsingborg's port. Fun for oyster lovers but boring for the environment
as this is invasive and does not really belong here.
Today, we can call Öresund for the world's most undervalued sea, for example, we have 100 times more fish than the big brother Kattegatt. Some claim 30 times and some claim 50 times but this is difficult to determine. More fish we have at least.
The latest report from the Öresund Water Cooperation in 2018 is only sports fish worth half a billion Swedish kronor a year.

Read the report: THE VALUE TO SOCIETY OF THE
FISH IN ÖRESUND

Now, history does not end here, we still have lots of things that need improvement to make this a long-lasting life for the Sound. The treatment plants today have problems with the fact that it is raining heavier and more powerful and when the drainage systems are not completely exposed 100% from the water, the problems come. There, prey water and sewage will be mixed to the purification plants, and they must then release this unpolluted sea in high rainfall. This is called brooding and is usually unfortunately.
That is why we have not fully approved bathing in many places in Öresund during the summer months.
The next problem is that the knowledge of our daily water is not in common men, landslides run down into our wells and then untouched into the sea. Such a small thing like fimp or pussy snus presents huge problems for our ocean as they often end up eating food in the stomach of fish or breaking down into micro patches. Often this is done in pure ignorance. You do not want to rinse down to throw the fimps in the well on the street.
Now it is very relevant with plastic in the garden. This is now the price we can pay after all years of plastic consumption. Sad but true, but it makes this medial focus that more people get up so we'll be a little more scared of our water. The biggest problems are microplaster, which comes from eg washing fleece clothing, ghost breakage, car tire wear, wear of artificial lawns, skin care products, decomposition of general plastic debris and much more.

Many new organizations start creating activities to clean up our water. HSR is doing excellent work and fighting for both Sea and Land. But even small associations such as HSDK Delfinen in Helsingborg have gathered their members for several years and descend into the northern port of Helsingborg and pick up all the junk that has been there during the year. Some years there may be several containers with bikes and outdoor furniture beer cans, coffee mugs, plastic bugs, from nearby outdoor dining. Boat owners like dumpers start batteries from the boat engines, Refrigerators, Binoculars, Handtools.


Watch the movie from a real junk dive below in Norrahamnen Helsingborg. Here it is not as beautiful as the other Öresund. May well feel as a result of gathering many people in the same area.
