Short summary
Dense water created in high latitude regions flows at the bottom of the ocean, from one basin to the next, and contributes to the global ocean circulation. The flow between shallow and deeper basins occurs at straits such as the Faeroe Bank Channel as underwater streams of dense water. Their representation in ocean models is problematic. In the present article, we use a mathematical formulation of dense water plumes to show that the representation of these dense overflows can be improved.

During the 2023/2024 ice season, a high-resolution dataset of ice thickness was collected in the Bothnian Bay. The analysis of data revealed a significant frequency of thick deformed ice such that about 60 % was thicker than 1 m. Among the 5500 individually identified ice keels, 20 % had a keel depth larger than 5 m and 2 % a depth larger than 10 m. This type of high-resolution ice data can be of vital importance for design of offshore structures and evaluation of computer ice models.

Climate change influences estuaries and their ecosystems not only by rising temperatures but also by salinity changes. This modeling study highlights the magnitude and causes of the Baltic Sea salinity sensitivity to fresh water forcing and changed ocean salinity. The large sensitivity to increased fresh water forcing is shown to be caused by dilution of fresh water within the estuary, recirculation of much of the outflow water back into the estuary, as well as decreasing inflows of ocean water.

The health of the Baltic and North seas is threatened due to high anthropogenic pressure; thus, different methods to assess the status of these regions are urgently needed. Here, we validated a novel model simulating the ocean dynamics and biogeochemistry of the Baltic and North seas that can be used to create future climate and nutrient scenarios, contribute to European initiatives on de-eutrophication, and provide water quality advice and support on nutrient load reductions for both seas.

We use data crossing Herald Canyon in the Chukchi Sea collected in 2008 and 2014 together with numerical modelling to investigate the circulation in the western Chukchi Sea. A large fraction of water from the Chukchi Sea enters the East Siberian Sea south of Wrangel Island and circulates in an anticyclonic direction around the island. To assess the differences between years, we use numerical modelling results, which show that high-frequency variability dominates the flow in Herald Canyon.

Short summary
Mesoscale ocean eddies (10–100 km) are crucial for transporting heat and salt in global circulation. While traditionally parameterized in ocean models, advances in computational power allow them to be partly resolved, questioning whether parameterizations should be used in this regime. We examine implications for Atlantic water circulation and heat transport to the Arctic, highlighting challenges in using – or omitting – mesoscale eddy parameterizations.
