Spatial heterogeneity in the structure of the planktonic food web in the North Sea
The distributions of bacteria, phytoplankton, protozooplankton and copepod biomass and activity were examined in relation to hydrographic characteristics of the water column on 2 cruises in the North…

Annual distribution and activity of phytoplankton in the Skagerrak/ Kattegat frontal region
TLDR
Phytoplankton biomass was shown to be significantly higher in the frontal region than in surrounding waters and, during periods when light limitation of primary production was predicted, the biomass maximum associated with the front was found in the weakly stratified waters bordering the front.

Primary production in the Kattegat: Past and present
TLDR
In this study, the evidence for increased primary production in the Kattegat is examined by comparing primary production measurements from the 1950s and measurements made in the period 1984-1993.

Global occurrence and heterogeneity of the Roseobacter-clade species Ruegeria mobilis
TLDR
The data and the TARA data demonstrate that R. mobilis is a globally distributed marine bacterial species found primarily in the upper open oceans, but contains diverse sub-clusters, which could provide new capabilities for utilization in aquaculture.

Development of an isotope dilution laser ablation ICP-MS method for multi-element determination in crude and fuel oil samples
An inductively coupled plasma isotope dilution mass spectrometric (ICP-IDMS) method with direct introduction of the isotope-diluted sample into the plasma by laser ablation was developed for…

Isotope dilution ICP-MS with laser-assisted sample introduction for direct determination of sulfur in petroleum products
TLDR
This method was developed for accurate sulfur determinations in different petroleum products such as ‘sulfur-free’ premium gasoline, diesel fuel, and heating oil and demonstrated the accuracy of the new LA-ICP-IDMS method in the concentration range of 9.2 μg g−1 to 10.4 mg g −1.

Development of a species-unspecific isotope dilution GC-ICPMS method for possible routine quantification of sulfur species in petroleum products.
TLDR
The low detection limit of 9 ng sulfur per gram sample, independent of results on coeluting hydrocarbons, and the robust instrumental design of the continuous spike flow dosing unit qualifies this species-unspecific GC-ICP-IDMS method for accurate and sensitive sulfur multispecies determinations also on a routine basis.

Accurate determination of sulfur in gasoline and related fuel samples using isotope dilution ICP–MS with direct sample injection and microwave-assisted digestion
TLDR
The results from both ICP– IDMS methods agree well with the certified values of the reference materials and also with each other for analyses of other samples, however, the standard deviation of DIHEN–ICP–IDMS was about a factor of two higher compared with those of wet-chemical ICP-IDMS, mainly due to inhomogeneities of the micro-emulsion, which causes additional plasma instabilities.

Development of an accurate, sensitive, and robust isotope dilution laser ablation ICP-MS method for simultaneous multi-element analysis (chlorine, sulfur, and heavy metals) in coal samples
TLDR
The developed LA-ICP-IDMS method with its simple sample pretreatment opens the possibility for accurate, fast, and highly sensitive determinations of environmentally critical contaminants in coal as well as of trace impurities in similar sample materials like graphite powder and activated charcoal on a routine basis.
