Abstract [en]

Today, laboratories involved in national or international marine monitoring programmes are strongly encouraged to seek accreditation or another formal proof of competence, The question often asked is whether a laboratory actually produces more reliable data when a quality system has been set up. A method of monitoring the differences in laboratory performance from year to year is presented in this paper. In the case of the SMHI Oceanographical Laboratory there has been substantial improvement in laboratory performance since formal quality assurance measures were introduced.

Abstract [en]

Two chlorofluorocarbons (CFC-11 and carbon tetrachloride, CCl4) widely used as tracers for dating water masses, were measured in the Gotland Basin of the Baltic Sea. At the time of the survey, the bottom water of the basin had remained stagnant for 15 years and anoxic for about the same period of time, and the concentrations of both CFC-11 and CCl4 decrease dramatically with depth below the mixed layer. Furthermore, the ratio of CFC-11 to CCl4 increases with depth under the mixed layer along with a steep decrease in oxygen concentration. This is contrary to what would be expected from the atmospheric histories. The most plausible explanation for this is that there is a mechanism whereby the CCl4 is removed from the water mass under anoxic and suboxic conditions.

Abstract [en]

The origin of bromoform in seawater and atmosphere, as well as possible sinks and breakdown mechanisms, is discussed. A bromoform budget is calculated for the Kattegatt area between Sweden and Denmark, where the input of bromoform from a power plant is significant. Both anthropogenically (250 x 10(6) g yr-1) and biogenically (350 x 10(6) g yr-1, 0.016 g m-2 yr-1) produced bromoform is likely to have a great impact locally on the inventory and the release to the atmosphere. Using measured sur-face concentrations of bromoform, the total annual release from the Kattegatt to the atmosphere is estimated to 550 x 10(6) g (0.025 g m-2 yr-1).
