Ferocious Chill Conquers Baltic Coast: Thin Ice Threatens Navigation
The chilly temperatures sweeping across Germany have caused ice to form precariously along the Baltic Sea's shores, especially in enclosed areas. As per the BSH's (Federal Maritime and Hydrographic Agency) ice report on Wednesday, locations such as Ueckermünde, Greifswald Wieck, and Wismar's ports, as well as some parts of the Peene Current, are affected by this developing ice. Witnesses have also spotted new ice and shards in smaller, sheltered sites up to the Schlei, while open bodies of water like Bodden near Zingst, are seeing the appearance of thin ice in the water.
The Baltic Sea's Waterways and Shipping Authority (WSA) had previously cautioned sailors about the likelihood of ice formation, urging them to exercise caution and only navigate using vessels equipped to handle icy conditions. The BSH has predicted that while more ice will form in the coming days, existing sheets will remain largely unchanged. Temperatures along the coast are expected to climb to more favorable levels, accelerating the ice's eventual dissolution when the weekend arrives.
- Shipping's Slump in the Baltic Sea
In contrast to coastal areas in Mecklenburg-Vorpommern, such as Greifswald Wieck and Ueckermünde, the waters of Schleswig-Holstein remain ice-free due to its larger, unobstructed bodies of water. The decline in the shipbuilding sector across various Baltic coast cities, including stalwarts like Wismar and Rostock, has resulted in lower demand for icebreakers, making winter navigation more challenging.
- Warning Signs and Cautionary Measures
Warnings signs have been posted along key maritime thoroughfares, such as the Peene Current and the Schlei, due to the presence of thin ice, posing a considerable risk to maritime traffic and its sailors. As the makeup of ice varies, visitors to these areas must exercise caution to avoid collisions with ice floes or hazards concealed beneath the surface. For instance, pancake ice, ice cakes, and drift ice pose substantial navigation challenges, particularly in enclosed areas.
- Potential Risks for Megaload Routes
The Megaload routes traversing Germany, including coastal roads, demand utmost caution. Thin ice and the possibility of huge icebergs necessitate careful navigation to assure safe cargo transportation.
- Relief for the Maritime Community
The anticipated end to ice formation along the coast provides much-needed relief for the maritime communities. Once navigation is deemed safe, the increase in seaborne cargo and passenger traffic can stimulate economic growth and recover lost momentum to regional industries.

Enrichment Data:
- Ice Accretion: Ice accretion, an amalgamation of ice particles and ice-covered salt on sea surfaces, can arise when the sea surface temperature dips below 4°C, resulting in the significant increase of a ship's overall weight by hundreds of tons. This can alter a ship's stability, steering, and usability, potentially causing equipment failure.
- Ice Thickness and Types: Information on ice thickness and types in the Baltic Sea can be obtained through the Norwegian Ice Service reports, which employ the Baltic Sea Ice Code to classify ice (SB) thickness and ice types (TB). For example, areas with close-packed ice (6/10-8/10 ice) with grey-white ice (15-30 cm) can provide formidable challenges for navigation.
- Navigation Precautions: Vessels that navigate in ice-laden waters must take various precautions. These include securing essential icebreaker services, hiring ice pilots, thoughtful passage planning, properly regulating sea water cooling, shielding propellers, and modifying draught and trim to keep the propeller submerged.
- Protected Coastal Areas: While enclosed coastal areas like Wismar and Greifswald Wieck may not face the same icy conditions as open seas, they can still harbor local ice accretion that necessitates careful navigation. Pancake ice, ice cakes, and drifting ice less than 20 meters wide can still make navigation tricky.
- Information Sources: Reliable and up-to-date information on winter navigation in the Baltic Sea region can be obtained via www.baltice.org, which provides extensive ice navigation recommendations, guidelines, and preparatory checklists.
