Despite the Baltic Sea being one of the most intensive shipping regions in the world the potential magnitude of the biofouled hulls in this region is unknown. This study estimated the biofouling load to Baltic Sea Region (BSR) based on the wetted surface area (WSA) method with regard to country, ship type and donor bioregion. WSA flux reached 656 km, of which 86% was associated with ships operating inside and 14% was WSA flux brought by ships from outside of the Baltic Sea. Most of the WSA was transported to Swedish, Finnish and Danish ports as well. The highest WSA flux was assigned to roll-on/roll-off, passenger and general cargo ships. The high biofouling potential in BSR indicates a potential high risk to the environment and, therefore there is an urgent need for appropriate guidelines to be introduced into daily use by the commercial shipping community.

Resurrection of a diatom after 7000 years from anoxic Baltic Sea sediment.
ISME J

Biological Oceanography, Leibniz Institute for Baltic Sea Research Warnemünde, Rostock, 18119 Germany.
Dormancy is a wide-spread key life history trait observed across the tree of life. Many plankton species form dormant cells stages that accumulate in aquatic sediments and under anoxic conditions, form chronological records of past species and population dynamics under changing environmental conditions. Here we report on the germination of a microscopic alga, the abundant marine diatom Skeletonema marinoi that had remained dormant for up to 6871 ± 140 years in anoxic sediments of the Baltic Sea and resumed growth when exposed to oxygen and light.

Waste and Resource Management, Rostock University, Justus-Von-Liebig-Weg 6, 18059, Rostock, Germany.
We conducted surveys of Mediterranean beaches in Egypt, Morocco, and Tunisia including 37 macro-litter (> 25 mm) and 41 meso-litter (5-25 mm) assessments. Our study identified key litter items and assessed pollution sources on urban, semi-urban, tourist, and semi-rural beaches. Macro-litter concentration averaged 5032 ± 4919 pieces per 100 m or 1.

Microplastics in seawater and fish from the Baltic Sea were analyzed. The significant contribution of the study is due to extensive collection of fish and surface water samples from corresponding fishing zones. Microplastics were detected in 100 % of seawater and 61 % of fish samples.

Department of Medical Biochemistry and Microbiology, Uppsala University, Uppsala, Sweden.
The circumstances under which species diversify to genetically distinct lineages is a fundamental question in biology. Atlantic herring (Clupea harengus) is an extremely abundant zooplanktivorous species that is subdivided into multiple ecotypes that differ regarding spawning time and genetic adaption to local environmental conditions such as temperature, salinity, and light conditions. Here we show using whole genome analysis that multiple populations of piscivorous (fish-eating) herring have evolved sympatrically after the colonization of the brackish Baltic Sea within the last 8000 years postglaciation.

Objective: To establish the relevance of examining the internal organs for the presence of diatom plankton after drowning in the waters of the White Sea.
Material And Methods: We studied the biological material (fragments of lungs and kidneys) from the corpses of people found in the waters of the Kemskaya Bay and Onega Bay of the White Sea and waters from different areas of the White Sea for the presence of diatoms.
Results: In all cases of drowning in the waters of the White Sea (in the area of the city of Belomorsk and the Kem skerries), marine and freshwater diatoms were found in the lungs and kidneys of the deceased in quantities sufficient to diagnose death from drowning in water.
