The geology of the Baltic Sea is characterized by having areas located both at the Baltic Shield of the East European Craton and in the Danish-North German-Polish Caledonides. Historical geologists make a distinction between the current Baltic Sea depression, formed in the Cenozoic era, and the much older sedimentary basins whose sediments are ...
The gulf is a combination of the Bothnian Bay in the north and the Bothnian Sea in the south, separated by the Kvarken region with a water depth of around 25 metres (82 ft) and a rate of land rising of almost 10 mm (0.39 inches) a year. Within 2000 years the bay is expected to separate from the rest of the gulf and become a freshwater lake.
On 26 September 2022, a series of underwater explosions and consequent gas leaks occurred on 3 of 4 pipes of the Nord Stream 1 (NS1) and Nord Stream 2 (NS2) natural gas pipelines, two of 23 gas pipelines between Europe and Russia. [ 8 ] Both pipelines were built to transport natural gas from Russia to Germany through the Baltic Sea, and are ...
Gulf of Finland Satellite image showing the gulf entirely frozen over in January 2003. The gulf has an area of 30,000 km 2 (12,000 sq mi). [2] The length (from the Hanko Peninsula to Saint Petersburg) is 400 km (250 mi) and the width varies from 70 km (43 mi) near the entrance to 130 km (81 mi) on the meridian of Moshchny Island; in the Neva Bay, it decreases to 12 km (7.5 mi).
The Western Gotland Basin contains Landsort Deep, which is the deepest spot of the Baltic sea (459 metres deep). The Gotland Basin is marked by the numbers 7, 8 and 10 in this map of the area's marine environment. The sediments in the Gotland Basin are important for studying the climate changes in northern Europe over the past 5,000 years.
The trench running on the bottom of the Sea of Åland contains the second-deepest spot of the Baltic Sea, at a depth of 301 meters, which is second only to Landsort Deep. The mean depth of Åland Sea is 75 m, area 5,477 km 2 and its volume is 411 km 3 . [ 1 ]
It is the 4th longest river in the Baltic Sea basin. Over its entire length, 436 km (271 mi) flows in Belarus [2] and 359 km (223 mi) in Lithuania. A 116 km (72 mi) stretch is the border between Lithuania and Russia's Kaliningrad oblast. Its greatest depth is 5 m (16 ft), and at its widest it extends about 500 m (1,600 ft).
