around 5 meters, because of a slightly warmer water layer under the surface layer. In the Sound, there was a strong halocline around 14–20 meters. In the Kattegat it was for the season normal and low concentrations of DIN and phosphate in the surface water (0–10 m). The levels of phosphate varied between Last updated: Apr 23, 2019

coast in the mouth of the Gullmar´s fjord. The Kattegat and the Sound Surface water temperatures varied between 12.0 and 12.7OC, which is above average in May. The thermocline and halocline were both located at a depth of 7-8 metres, somewhat more shallow at Anholt E. The nutrient concentrations were Last updated: Apr 23, 2014

10 metres and the thermocline at 20 metres. In the Sound both the thermo- and halocline were at about 13 metres. The surface salinity was now normal, about 20 psu. The phosphate concentration in the Kattegat was 0.05 µmol/l and in the Sound higher than normal, 0.24 µmol/l. The nitrate concentrations Last updated: Apr 23, 2014

University of Göteborg (FRISBEE-project) was ended. The Skagerrak Surface water temperatures were much over normal. The temperature was 17.9°C at the outer part of the Å-transect and increased to 20.5oC at the coast in the south. The surface salinity was normal in the central Skagerrak (Å 17), 30 psu, while Last updated: Apr 23, 2014

The cruise was initially delayed for some hours, and there were some problems with the generators resulting in inability to maintain full speed of the vessel during the cruise. Shortly before arriving Lysekil, information was given stating that other bookings of R/V Aranda had priority, and the Last updated: Mar 15, 2019

influence absorption Increased absorption of carbon dioxide by the sea has a positive effect on the atmosphere, since it slows down the escalating greenhouse effect. However there are indications that increased absorption of carbon dioxide in the sea would change the pH value of the sea with a tendency Last updated: Sep 03, 2019

climate models, the warm period of May to August 2018 was compared with a total of 20,580 model simulations of equivalent four-month periods during the past 70 years. “We can see that the large amount of data includes summers that resemble that of 2018, but they are extremely unusual. They occur in no Last updated: Jan 27, 2021

concentrations were low, as is normal in the summer. The dissolved inorganic nitrogen was depleted down to the halocline both at the West coast and in the Baltic Proper while phosphate remained in the surface water, although at low levels.    Acute hypoxia (< 2ml/l) was noted from 70 meters in the Baltic Proper Last updated: Aug 28, 2019
