. Filamentous (threadlike) cyanobacteria were abundant though at most stations, both surface samples and integrated (0-10m) samples. Nodularia spumigena* and Aphanizomenon flos-aque were both very common at most of the stations. Aggregations of cyanobacteria were visible as grains in the water in the northern Last updated: Jul 29, 2015

performed during the cruise. The Skagerrak Both temperature and salinity in the surface water was normal for this season and varied around 17°C and 31-32 psu respectively. The halocline was weakly developed along the coast and the thermocline was found between 50 and 80 meters depths. In the western parts Last updated: Apr 23, 2014

Nutrient concentrations in Skagerrak and Kattegat were normal for the season. In the Sound silicate concentrations were enhanced. The other nutrients showed normal values. Inorganic nitrogen (DIN) had been consumed in the coastal waters of Skagerrak and in Kattegat and in all stations in the Baltic Last updated: Apr 23, 2014

In the Skagerrak and Kattegat, surface water temperatures were normal and sea surface salinity lower than normal. Surface temperatures and salinities were normal for the time of year in the Baltic. Nutrient concentrations in surface waters were normal in most of the region, with the exception of Last updated: Apr 23, 2014

the south-eastern part of the investigated area. Characteristic streaks and flocculations in the surface were observed around the sampling station. Extra surface samples were collected for further investigation. Fluorescence measurement indicated plankton activity in the whole area. PARTICIPANTS Name Last updated: Apr 23, 2014

plan will be based on a review of gaps between the monitoring requirements set in the international legislation and the existing monitoring and data management in the Baltic Sea. The possibility to use novel monitoring methods to improve and support the existing monitoring will also be evaluated. At Last updated: Dec 05, 2018

Skagerrak The surface temperatures varied between 3.3 and 4.8 oC and surface salinites from 24 psu in the Baltic water to 33.5 in the remaining area. The spring bloom was almost over, except along the Jutland coast where nitrogen rich water from the North Sea was found. Kattegat and the Sound The Last updated: Apr 23, 2014
