Short summary
Short summary
Eight current meters were deployed to the seafloor across the Baltic to enhance knowledge about circulation and currents. The experiment was complemented by autonomous vehicles. Stable circulation patterns were observed at the sea when weather was steady. Strong and quite persistent currents were observed at the key passage for the deep-water renewal of the Northern Baltic Sea. Deep water renewal mostly occurs during spring and summer periods in the northern Baltic Sea.

Short summary
Comparisons of oceanographic climate data from different models often suffer from different model setups, forcing fields, and output of variables. This paper provides a protocol to harmonize these elements to set up multidecadal simulations for the Baltic Sea, a marginal sea in Europe. First results are shown from six different model simulations from four different model platforms. Topical studies for upwelling, marine heat waves, and stratification are also assessed.

Short summary
An extensive measurement campaign and numerical simulations were conducted in the central Baltic Sea. The persistent circulation patterns were detected in steady weather conditions. The patterns included various circulation features. A coastal boundary current was observed along the eastern coast. The deep layer current towards the north was detected as well. This current is an important deeper limb of the overturning circulation of the Baltic Sea. The circulation regime has an annual cycle.

Short summary
Short summary
The upper mixed layer, shallower than the depth of the euphotic zone, is one of the preconditions for enhanced primary production in the ocean. In the Baltic Sea, the general understanding is that the upper mixed layer is much deeper in winter. In this study, we demonstrate that wintertime shallow stratification and an elevated phytoplankton biomass proxy, chlorophyll, are common in the Gulf of Finland. Stratification is invoked by the westward flow of riverine water forced by an easterly wind.

Short summary
Based on hydrography data (2002–2015) it was found that the average geostrophic volume transport of Atlantic water (AW) decreases along the Eurasian Basin slope from 103º E to 142º E and has a small value in the Makarov Basin. Maximum values of the AW volume transport, temperature, and salinity were observed in 2006. A trend of increase in AW salinity over time (AW salinization in early 2000s) was discovered. These results can be useful to anyone interested in recent change in the Arctic Ocean.

Short summary
Spiral streaks or spirals are a common feature on satellite images of the sea surface. Spirals are overwhelmingly cyclonic: they wind anticlockwise in the Northern Hemisphere. Based on a regional circulation model with very high resolution we concluded that submesoscale cyclonic eddies differ from anticyclonic eddies in three ways favoring the formation of spirals: they can be characterized by (a) higher angular velocity, (b) more pronounced differential rotation and (c) negative helicity.
