I love your work and know that you need to funding to continue, but if you are in a position to be selective about who you advertise I would ask that you look into criticisms of betterhelp. They have a history of false advertising, breaches of privacy and predatory practices. In this day and age that is more the rule than the exception, however since they are specifically targeting vulnerable people there is an extra layer of evil to it.

Usually, in school, the geological history of the Baltic Sea, the world's largest inland brackish sea, starts with the end of the ice age about 10-15 KA and tells about its different stages before it became the current sea about 4,000 years ago. However, the geological history of the Baltic Sea is much, much older and began when the Baltic plate subducted against the Laurentia (North American) plate around 400-450 Ma. At that time, the western Scandian orogeny and the central plate depression were born on the plate, which became important millions of years later. But from the Cambrian period to the Silurian period, there was a shallow sea in the middle of the Baltic plate, which began to be filled by erosion from sediments from the Scandian mountains. During the Cretaceous period, based on the discoveries in Kristianstad basin 86.3-71.3 Ma, there were dinosaurs such as theropods, leptoceratopsids, hypsilophodonts, hadrosaurids, iguanodontids and hesperornitheans who roamed the area as well as pterosaurs, mosasaurs, tylosaurs, plesiosaurs and crocodiles. In addition, there were two local meteor impacts, one on Dellen (~89 MA) and a later one on Lappajärvi (~78 MA) before the more famous K-Pg event. Around 40 MA, by the Eocene period, a wide plain had formed at the site of the more ancient depression. The plain was dominated by the amber-producing coniferous forest that covered it and through it flowed the "Baltic River System" now called as Eridanos. This Eridanos river ran along the previously mentioned depression to the Polish coast and later to the coast of the Netherlands because the river pushed its delta forward and the sea level also started to drop. Then began the Quaternary ice ages 475-370 KA (Elster, Saale and Weichselian, and between them the interglacials Holstein and Eem) and the glacier scooped out the old river bed several times. And between those ice ages it was filled with water like, for example, the Eemian Sea during the Eemian interglacial period about 127 KA. That would sum up the usually untold part of the geological history of the Baltic Sea.

Kattegat and the straits of Denmark, are not the Baltic sea. The International Hydrographic Organization defines the limits of the Baltic Sea as follows: Bordered by the coasts of Germany, Denmark, Poland, Sweden, Finland, Russia, Estonia, Latvia, and Lithuania, it extends north-eastward of the following limits: In the Little Belt. A line joining Falshöft (54°47′N 9°57.5′E) and Vejsnæs Nakke (Ærø: 54°49′N 10°26′E). In the Great Belt. A line joining Gulstav (South extreme of Langeland Island) and Kappel Kirke (54°46′N 11°01′E) on Island of Lolland. In the Guldborg Sound. A line joining Flinthorne-Rev and Skjelby (54°38′N 11°53′E).

About capitals and former capitals, you forgot to mention the former capital of Finland, Turku.

[@Hoksaaja]

Turku has never been the capital of Finland. During Sweden it was Stockholm, during Russia Helsinki and during independence Helsinki, never Turku

[@kitsunefromfinland4145]

Turku was the capital of the Great Duchy of Finland for 3 years during the Russian era. Making it at the time the most important city in the area called Finland. The first Finnish senate, Bank of Finland and many institutes started in Turku in that 3 year time, later moved to Helsinki when the Tsar moved the capital there. During the Swedesh era Stocholm was the capital, Turku hold the position of the most important city in the Finnish area (btw the name Finland comes from the area where Turku is located, thats why the region is called Finland Proper). First Finnish school (Turun katedraalikoulu), first university (Royal Academy of Turku) and for example the only medieval cathedral in Finland gives you idea how powerful position Turku had compared to for example Helsinki. Much much later Helsinki stole most of these achievements for example the Academy was moved to Helsinki and became Helsinki university. So yes, technically Turku has only been the capital for 3 years, but for over 600 years it hold almost absolute power in the Finnish area, only the city of Viipuri being another big city in the area. @@Hoksaaja

[@MrGunnar69]

Or Göta Kanal when he mentioned other canals. The Öresund Bridge was not mentioned either.

[@SaunaFinland]

Not saying the Stockholm Archipelago doesn't deserve a mention, it certainly does. But, how do you mean it's significantly larger? The Stockholm Archipelago has 34 000 islands, while the Finnish Archipelago has more than 50 000 islands. Also, the Finnish Archipelago is spread out on an obviously much larger surface area, so what definition would you apply to point out it's larger? Even in Swedish Wikipedia it says about Stockholms skärgård: "Den räknas som Sveriges största skärgård och den näst största i Östersjön, efter Skärgårdshavet i sydvästra Finland."

[@maxgronros6728]

@@SaunaFinland That is very true. But the entire video did fail to menion annyhing abou sweden at almost every chance it had to mention it. He stopped talking about the coast right as he was done with finland and as stated above he failed to mention a single project in sweden like göta kanal. The fact that sweden has the most islands in the world is also an interesting fact that he somehow failed to mention, mentioning that would have done the same thing as mentioning finlands big archepelego but in a much better way.. The entire video seemed to have been made by a danish person that never really got the memo that our countries are no longer enemys but friends 😂

@@maxgronros6728 I agree. There was pitifully little about Sweden, which is a shame, because Sweden is an amazing country with beautiful seascapes.

[@rickrutledge9363]

Sounds like a high school lecture

[@qualicumwilson5168]

One possible point of interest the was not noted is that the Baltic Sea has the lowest salinity of any portion of the worlds oceans and seas. This is partially due to the high rainfall and ergo high fresh water flow into the sea. But a larger formative cause is the very low tides around Copenhagen, which are are 30 cm or less, which creates minimal mixing of North sea and Baltic sea waters.. Another interesting fact is the the Baltic sea Salmon remain within the sea and their numbers did not have the huge declines caused by Greenland overfishing of all other Salmon races.
