Cruise report from R/V Argos week 12, 2008

Nutrient concentrations were higher than normal for the season in the central Skagerrak. Phosphate and silicate concentrations were enhanced in the southern Baltic and in the Sound. Measurements of fluorescence and oxygen saturation indicated that the spring bloom was underway in the Kattegat and southeastern...

Cruise report from R/V Argos week 9-11, 2008

Oxygen conditions in the main part of the Hanö Bight, around the Midsjö Banks and in the Northern part of the Bornholm Basin were good. Oxygen concentrations below 2 ml/l were found, both west and east of Gotland, at depths excceding 70-80 metres. Hydrogen sulphide was found at three stations west of...

Cruise report from R/V Argos week 8, 2008

The water temperature was to some extent elevated in the north Baltic Proper. Nutrient concentrations were normal in most basins with the exception of the southern and eastern parts of the Baltic Proper where phosphate showed elevated concentrations. The spring blooms had not started in the Baltic Proper...

Cruise report from R/V Argos week 4-6, 2008

Kattegatt and the Sound nutrient concentrations showed normal values. The oxygen condition in the bottom waters of the area was good and most stations showed values over 90% oxygen saturation. The spring bloom had not yet started.

Cruise report from R/V Argos week 3, 2008

Surface water temperatures were somewhat above normal in Kattegat and the Baltic Proper. All nutrients, showed normal winter values in the whole area, with the exception of phosphate, that showed elevated concentrations in the Southern Baltic Proper. In no areas, any sign of spring bloom was detected...

Cruise report from R/V Argos week 9-11, 2007

Oxygen conditions in the main part of the Hanö Bight, east of Öland, around the Midsjö Banks and in the Northern part of the Bornholm Basin were good. Below 70-80 metres depth, both west and east of Gotland, oxygen concentrations were below 2 ml/l. Hydrogen Sulphide was found at three stations west of...

Cruise report from R/V Argos week 12, 2007

In the Southern Baltic Proper, concentrations of phosphate and silicate in surface waters remain high, while nitrate concentrations were normal. Nutrient concentrations in the Skagerrak and the Kattegat were normal for the season throughout the study area. There was an algal bloom along the Swedish west...

Cruise report from R/V Argos week 8, 2007

High concentrations of phosphate were measured in the surface water of the southern Baltic. Silicate concentrations were also enhanced while nitrogen showed normal values. On the West-Coast nutrients concentrations, except for silicate, were normal or close to normal. Silicate concentrations in the Skagerrak...

Cruise report from R/V Argos week 4-6, 2007

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 stations...

Cruise report from R/V Argos week 3, 2007

Surface water temperatures were above normal in all areas. Surface salinities were high in the Kattegat and the Sound and an inflow to the Baltic occurred the week before the expedition. In the Southern Baltic Proper concentrations of phosphate were raised in the surface water. Otherwise, nutrient concentrations...
