Ziel der Reise / Objectives of Cruise:
The Swedish National Board of Fisheries carried out the cruise within the framework of the ICES coordinated 'Baltic International Trawl Survey'. Personnel from SMHI Oceanographic Services were responsible for hydrographic observations that support the fisheries investigation. Water bottle series (temperature; salinity and oxygen in deep & bottom water) were taken at 54 stations. CTD casts were recorded at 53 of these. Hydrographic conditions in the greater part of the Hano Bight, the Northern Bornholm Basin , around the Midsjo Banks and east of Oland were favourable for cod and no oxygen concentrations below 2 ml/l were recorded. Below 70 to 95 metres depth, both west and east of Gotland, oxygen concentrations were below 2 ml/l. Hydrogen Sulphide was not found at any station. A fisheries cruise report is available from the National Board of Fisheries (www.fiskeriverket.se) The visited frequent stations, BY13, BY38, BY4 and BY5 in the Baltic Proper measured very high surface phosphate and silicate concentrations, while levels of nitrogen compounds were normal. At the frequent visited station Anholt E in the Kattegatt, the spring bloom was at the end and the nutrient concentrations were very low.
