Oxygen concentrations close to zero were observed in all deep water areas in the Baltic Proper. Anoxic conditions, when hydrogen sulphide forms, were measured in the Western Gotland Basin from about 70 metres depth, in the Eastern Gotland Basin intermediate at 80 meters and nearest the bottom at …

SMHI can provide probability estimates and return periods to be used when analyzing observed weather events or when dimensioning sensitive equipment, infrastructure or buildings.

A wind rose gives you an idea of the prevailing wind directions and wind speeds for a specific location, information often required in the planning process or when applying for construction permits. We can provide an analytical report with wind roses describing the wind conditions at any of our …

Results from the Swedish national marine monitoring in the pelagic during 2016 are presented. The institutes who conduct the national monitoring are SMHI (Swedish meteorological and hydrological institute), SU (Stockholm University) and UMF (Umeå marine sciences centre). The presented parameters …

The Swedish OSPAR waters were assessed by applying the OSPAR Common Procedure for the time period 2006 – 2014. The Swedish parts of Skagerrak, Kattegat and the Sound constitute the outer part of the transition zone between the estuarine Baltic Sea and the oceanic North Sea and were investigated for …

The diatom Proboscia alata was found in high concentrations at all stations in the Skagerrak and in Kat-tegat. The species diversity was generally low at all west coast stations. One or two chlorophyll maxima were found at all stations, mainly caused by P. alata and also by different species …

Oxygen concentrations close to zero were observed in the deep water everywhere in the Baltic Proper except for in the Arkona Basin. Anoxic conditions, when hydrogen sulphide forms, were measured in the Western Gotland Basin from about 80 metres depth, in the Eastern Gotland Basin nearest the bottom …

Different scenarios and for some parameters observations are used to explain the development of the ocean climate in the Baltic Sea and the North Sea. The scenarios show further how the climate could continue to develop in the area during the 21st century.

The phytoplankton diversity was generally low in the Kattegat and Skagerrak areas. Rather small chlorophyll fluorescence peaks were caused by a few diatom species and the dinoflagellate genus Ceratium. The summer bloom of cyanobacteria was ongoing in the Baltic Sea. Aphanizomenon flos-aquae …
