## 1. How long is the coastline of the Baltic Sea?

To start off, do you know how long the Baltic coastline is? Below you can see satellite images of our sea with the visible coastline.

The coastline of the Baltic Sea is 8,100 kilometers long. To put it into perspective, let’s compare it to the longest railway line in Poland that connects Świnoujście and Przemyśl. It is 986 kilometers long, so we would have to travel it more than 8 times to cover the distance equal to the coastline of our sea.

## 2. How many seals live in the Baltic Sea?

The second fact is about the seals that live in the Baltic Sea. Do you know that their population is around 40,000 individuals? Is that a lot? It is worth mentioning that about 100 years ago, there were about 100,000 seals living here.

Interestingly, due to water pollution and mass killing of these beautiful animals by humans, their population decreased to only 3,000 at one point in the 1970s. Thanks to efforts to save their population that started in the 1980s, it has been increased to the mentioned 40,000. These fluctuations clearly show the impact that humans have on species living with us, and it is up to us whether it will be positive or negative.

## 3. Where is the deepest point in the Baltic Sea and how deep is it?

The deepest point in the Baltic Sea is the Landsort Deep, located several kilometers from Stockholm, Sweden. It measures a staggering 459 meters below sea level. To show you the scale of this depth, let me tell you that it would be almost enough to submerge two Culture and Science Palaces in Warsaw, where each of them with antennas measures 237 meters. Above water, only 15 meters of the antennas would stick out.

## 4. How many countries are located on the Baltic Sea?

Can you say exactly how many countries are located on the Baltic Sea and name them? Personally, I had to refresh my knowledge.

On the Baltic Sea, there are 9 countries. These are Poland, Lithuania, Latvia, Estonia, Russia, Finland, Sweden, Denmark, and Germany. Quite a lot for a relatively small sea.

## 5. What is the salinity of the Baltic Sea?

Anyone who has been to the Baltic Sea and swam in it can confirm that the water is salty. But do you know how saline our sea is? On average, it is 7 parts per thousand, which is not much as it equals about 7 grams of salt per liter of water. The most salty water is in the Danish straits, Kattegat, and Skagerrak, where the salinity reaches 20 parts per thousand.

For comparison, the Mediterranean Sea has a salinity of over 35 parts per thousand, and the Dead Sea has 260 parts per thousand, which is 26 percent.

## 6. Which island in the Baltic Sea is the largest?

Do you remember from geography which island in the Baltic Sea is the largest and what is its area?

It is the Swedish island of Gotland, with an area of 3,144 square kilometers and a population of over 57,000. It is truly a large area. For comparison, the area of the city of Warsaw is 517 square kilometers. So, several cities of this size could fit on the island.

## 7. How high are the waves in the Baltic Sea?

Many people, especially before a ship journey, wonder how high the waves in the Baltic Sea are. The average wave height of our sea is 5 meters. However, during storms, they often reach a height of 10 meters.

According to Wikipedia, in December 2004, during a storm in the northern Baltic Sea, a single wave nearly 14 meters high was recorded. Now, let’s compare these 10 or even 14 meters with our height, and we will realize that these are not low waves.

## 8. How many ports are located on the Baltic Sea?

The Baltic Sea is not very large. Are you aware that there are over 200 ports here, of which 190 handle over 50,000 tons of cargo annually?

And which one is the largest? In terms of cargo handling, Russian ports dominate, with Ust-Luga port handling over 98 million tons.
