high numbers at several stations. The integrated chlorophyll concentrations were normal at all stations for this month. The filamentous cyanobacterium Aphanizomenon flosaquae was abundant in the northern Baltic Proper and at REFM1V1 in the Kalmar sound. Filamentous cyanobacteria were absent or in very Last updated: Sep 10, 2021

SMHI performed an oxygen and nutrient survey within SLU Aqua’s cruise; the International Bottom Trawl Survey (IBTS Q3), that covers the Skagerrak, the North Sea and the Kattegat. SMHI joins the cruise to perform CTD measurements in connection to each trawl and to take water samples for the annual Last updated: Sep 10, 2021

. For more information on species composition see separate algae report "AlgAware". Nutrients in the form of dissolved inorganic nitrogen (DIN) and phosphorus (DIP) in the surface layer were generally at normal levels throughout the investigated area. The silicate concentrations in the southern Baltic Last updated: Apr 18, 2018

or less developed between 10 and 20 meters depth. The nutrients were influenced by the current spring bloom and were partially or almost completely consumed. Nutrients in the form of dissolved inorganic nitrogen, DIN (the sum of nitrate, nitrite and ammonia), were on normal levels for the season and Last updated: Jun 15, 2018

the Baltic Sea. However, there was no inflow event observed at the same time but a smaller inflow occurred a couple of days before. Smaller inflows have the tendency to be mixed in the Arkona Basin and then some of the water again flows out through the Sound. The sea surface temperature increased from Last updated: Jun 12, 2018

products were included. A regression equation for each location therefore had 252 variables to begin with. Stepwise multiple regression was thereafter applied for each site, which reduced the number of fäctors in the regression equations to 7-26. These relationships could then be applied to observed and Last updated: Mar 31, 2020

these mixotrophic species Mesodinium rubrum. The diatom genus Actinocyclus were found in moderate numbers. The community was otherwise dominated by very small cells in the size range of 1.5 -2 µm width. The integrated chlorophyll concentra- tions (0-10 m and 0-20 m) were within normal for this month Last updated: Sep 28, 2020

results in an easily accessible and meaningful way to those that need the information, such as water and wastewater organisations and the emergency services," says Jonas Olsson. We are increasing knowledge and understanding, finding the limitations of the different systems and models and tying them into Last updated: Jun 05, 2020

the halocline as a consequence of mineralisation. Some stations are reached by inflows of deep water with larger oxygen content and this some of the ammonia, a mineralisation product, is oxidised and the level of dissolved inorganic nitrogen decreases. This process is seen in the Bornholm Basin and in Last updated: Jul 19, 2017
