Category I). A hydraulic model was built to calculate water levels along the river at the different flow levels. The model was based on height data from laser scanning and river bottom data from sounding. The data sampling was carried out in cooperation between Swedish and Finnish authorities within the Last updated: Mar 20, 2017

-westerly and increased to 12-13 m/s. The Skagerrak Surface water temperatures were below normal (except coastal area) and varied between 1.9 and 3.0°C throughout the area. Surface salinities were normal, varying between 29-30 psu. The halocline and thermocline were very well defined and were both found at 8 Last updated: Apr 23, 2014

The expedition was included within National Board of Fisheries International Bottom Trawl Survey and covered the Skagerrak and the Kattegat and the Sound. Mapping of winter nutrient conditions was performed in the Skagerrak and 14 stations with complete hydrography were sampled. In the Kattegat 10 Last updated: Apr 23, 2014

The main aim of this work is to present data as typical concentration values for different nutrients in the various sea areas, and how these have varied over time. The data presented cover a 30 year period which include both increased eutrophication and years with efforts to reduce antropological Last updated: Apr 23, 2014

, ERA-CLIM and ERA-Interim). Further downscaled high-resolution reanalyses will also be performed where more near surface ECV observations can be utilized. Indicator information (including uncertainties) will be applied to the reanalyses and there will be extensive validation against remote sensing and Last updated: Jul 07, 2022

Fisheries carried out the cruise within the framework of the ICES co-ordinated 'Baltic International Trawl Survey'. Personnel from SMHI Oceanographic Services were responsible for hydrographic observations that support the fisheries investigation.

Board of Fisheries Cod Investigation Programme, BITS (Baltic International Trawl Survey) and covered parts of the Baltic Proper. Near-bottom salinity and oxygen measurements were done at 34 stations. Hydrogen sulphide was detected at 4 of these. N.B. Measurements were only made in minor areas in the Last updated: Apr 23, 2014

Hanö Bight, 0.86 to 1.01 µmol/l. In the other areas concentrations varied between 0.65 and 0.9 µmol/l. Also silicate showed increased concentrations in the Arkona Basin and Hanö Bight, between 12.5 and 16.5 µmol/l. In the remainder of the Baltic Proper these concentrations varied between 10.5 and 17 Last updated: Apr 23, 2014

species cf. Prymnesium polylepis was observed at BY2, REF M1V1 and at BY29. The chlorophyll a concentrations were somewhat high in the Southern Baltic, at stations BY5 and REF M1V1 the integrated concentrations were above average for this month.
