and the halocline was found at a depth of 10 metres. Nutrient concentrations in surface water showed normal levels phosphate ca.0.5, nitrate nitrite 3.5- 5 and silicate 4.5-7.5 µmol/l. High concentrations of ammonia were measured at the station P2 in the southeast, and at intermediate depths at Last updated: Apr 23, 2014

The integrated (0-20 m) chlorophyll concentrations were within normal for this month at most stations in the Kattegat and Skagerrak and chlorophyll fluorescence maxima in these areas were caused by diatoms. The diatoms Rhizosolenia spp., Chaetoceros decipiens and Thalassionema nitzschioides were Last updated: May 04, 2018

Nutrient levels were largely normal in the whole investigated area. In the Baltic Proper, oxygen concentrations below 2 ml/l (hypoxia) were found at depths exceeding 70 to 80 metres, while a total deficiency of oxygen (anoxia) was found below 70 to 125 metres.

stations during this cruise. There were no surface accumulations but cyanobacteria grains were observed in the water. 4CTRY BP 16th of June This station is sampled instead of BCSIII-10 for the time being.

situation before the salt water inflow 2014 and therefore the work with an extra series has now started again. The fluorescence measurements from the CTD showed low phytoplankton activity in the whole investigated area. Figure 2.

normal in this area. They increased from 8.1°C in the Sound to 8.8°C in the northern Kattegat. Surface salinities were higher than normal, ca. 28 psu in the northern part of Kattegat and 19 psu in the Sound, where an inflow to the Baltic was ongoing. Thermocline and halocline coincided and were found at Last updated: Apr 23, 2014

Surface water temperatures were normal, except in the southern Skagerrak, Kattegat and the Sound, where the temperature was some degrees higher than normal. The concentrations of phosphate and silicate in the southern Skagerrak were higher than normal. High ammonia values were found there as well Last updated: Apr 23, 2014

port on October 29. The weather during the expedition was mainly windy. The Skagerrak Surface water temperatures were normal. They varied between 11 and 12 °C. A thin surface layer with low salinity covered almost all of the investigated area. Only at Å17, furthest west, was surface salinity normal at Last updated: Apr 23, 2014

near gale force prevailed. The Skagerrak Surface water temperatures were normal throughout the investigated area. They varied between 14.5 °C at Å17 in the central part, to 17.2 °C at the coast. Surface salinities were normal, ca. 24 psu, at the coast and ca. 32 psu in the central parts. All nutrients Last updated: Apr 23, 2014
