In the Skagerrak and Kattegat, surface salinity was lower than normal, which indicates an influence of outflowing Baltic water. In the Baltic Proper the concentrations of phosphate and silicate were elevated in the Western Gotland Basin. The oxygen concentrations in the bottom water in Hanö …

A new cooperation between SMHI and the Finnish SYKE has started. This is the first AlgAware with data from samplings with the Finnish ship R/V Aranda. All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea contained low species diversities and all of the cell counts were …

In Skagerrak and Kattegat, surface salinity was much lower than usual, which indicate a strong influence of outflowing Baltic water. The mapping of nutrients in the Kattegat showed small variations and overall normal concentrations. In the Baltic Proper the concentrations of phosphate and silicate …

SMHI and SYKE, the Finnish Environment Institute, have begun a close collaboration to monitor the marine environment of the Baltic and the North Sea.

OceanWeb on smhi.se is now being re-launched in a new, more accessible form. OceanWeb is a web application for the visualization of ocean observations and forecasts for the seas around Sweden; the Baltic, Kattegat and Skagerrak.

The serious oxygen conditions that have affected the Baltic Sea during the 2000s continue. The oxygen survey performed during autumn 2013 show that 15% of the bottom areas are dead due to total absence of oxygen and about 30% suffer from acute oxygen deficiency.

A chemical mechanism, including the relevant reactions leading to the production of ozone and other photochemical oxidants, has been implemented in the MATCH regional tracer transport/chemistry/deposition model. The aim has been to develop a model platform that can be used as a basis for a range of …

The surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer, except silicate, showed normal concentrations. The oxygen concentrations in the bottom water of the Sound and Kattegat were higher than normal, but lower than normal in the …
