The Tynic Sea (Danish/West Tynlandic:Tynerhavet; Swedish: Tynerhavet; Norwegian/Tynlandic: Tynlandske Hav; Atlantican language: Tynirhavið; Fjallandic language: Tønsk Sjœr; Teutonian Language: Tynländische Meer) is a sea of the Great Ocean, enclosed by Sjealand, Tynland, West Tynland, and Holstein. It includes the Gulf of Tartarien, the Bay of Derling, the Gulf of Finland, the Grønnebugt Bay, Nølle Bay, the Gulf of Holstein, The Gulf of Reland, the Bay of Bathla, and the Gulf of Markid. An inland sea of the Great Ocean, with limited water exchange between the two bodies, the Tynic Sea drains through the islands of NAME into the Strait of Reland.
The Tynic Proper is bordered on its northern edge, by the Strait of Reland and is fully surrounded on all other sides by the continent of Nordania.
The Treaty of Marine respect and law concerning the Tynic Sea, signed by West Tynland, Sjealand and Holstein in 1992 (Tynland refused to take part due to the inclusion of the break-away state of West Tynland and ideological conflicts with the two others), established the legal end of the Tynic Sea as a straight line extending from the Stortanden Peninsula in Sjealand to the Dergal Peninsula in NAME. This includes parts of Great Ocean commonly not viewed as part of the Tynic Sea.
Geographers and oceanographers commonly agree that the geographical border of the Tynic Sea is beginning of the wider Nordanian continental shelf, beginning after the Isles of NAME and the West-Sjealandian Gabet. This follows the administrative border in most cases, only slightly deviating as the depth does. Commonly it is accepted that the Tynic Sea ends approximately 100 nautical miles north of the Isles of NAME.
Hydrography and biology
There are 34 islands in the Tynic Sea belonging to various countries which have coasts on the sea. Sixteen of those islands belong to Holstein, nine of which are found in the Runic Islands archipelago. The island of Mariensee is divided between Holstein and Tynland, making it the only island in the Tynic Sea to have a land border. Most of the islands are inhabited by small populations, with five islands being uninhabited, having been designated special conservation areas for seabirds. The largest and most populous within the Gulf of Holstein is Dänholm in the Runic Islands, which is home to the administrative capital and largest settlement in the islands, Lüdersholm. Around 89,300 people live within the islands in the Gulf of Holstein.
Hvidby (Weißburg) and Bernhafen are the two major ports in Holstein that like on the eastern coast of the Tynic Sea, with Bernhafen being the principle port. It is the largest port in Holstein and one of the largest in Nordania, handling 4.9 million TEU's annually. It acts as the primary gateway for cargo entering and exiting Holstein to countries outside of Nordania. Although smaller, Hvidby is also an important port along the coast as it contains the second largest ferry terminal in Holstein. Hvidby provides essential commercial ferry services to islands off the coast of Holstein, in addition to the Runic Islands at the maritime border between Sjealand and Holstein.
Sjealand is home to Asgård, the largest and busiest port city on the Tynic Sea. As one of the oldest cities in the region it has played a vital role in regional trade, acting as a hub leading into Nordania. It's docks are amongst Nordanias largest and alongside a yearly turnover of 2,1 billion Rigsdaler in 2015 a total of 2,754,233 tons of containers moved through the port.. Besides Asgård, the other major Sjealandian ports are the free cities of Holmegård and Miklagård. The cities of Hedeby and Birka along with Asgård also serve as important ferry terminals to The Royal Confederation of Holstein with especially profitable routes to the danish-speaking areas of Holstein.
Tynland has several major fishing towns near the Tynic Sea and also has a major port there with the city of Musland, which is known more for its port and its importance in shipping than for the city itself, which is located slightly to the northeast of the port. The city was built in the ancient days but revitalized in the 1800s, which was when the port was upgraded and became a major source of industrial traffic, being upgraded again in the 1950s after the Civil War.
