Bioavailability of trace elements in surface sediments from Kongsfjorden, Svalbard.
TL;DR: The evaluation of the bioavailable fractions showed that a large part of the total content of trace elements cannot enter the aquatic food chain and emphasised the risk of overestimating the environmental impact of heavy metals if the assessment is only based on total concentrations.

Methanesulphonic acid (MSA) stratigraphy from a Talos Dome ice core as a tool in depicting sea ice changes and southern atmospheric circulation over the previous 140 years
Silvia Becagli,Emiliano Castellano,O. Cerri,Mark A. J. Curran,Massimo Frezzotti,F. Marino,F. Marino,A. Morganti,Marco Proposito,Mirko Severi,Rita Traversi,Roberto Udisti +11 more
TL;DR: In this article, a spectral analysis was applied to the MSA, SOI (South Oscillation Index), and SAM (Southern Annular Mode) record, and the results showed a strong positive correlation and are synchronous with corresponding SOI periodicity, indicating that marine biogenic activity enhanced by large sea ice cover is an important factor in controlling MSA concentration in snow precipitation at Talos Dome.

Relationship between methanesulfonate (MS−) in atmospheric particulate and remotely sensed phytoplankton activity in oligo-mesotrophic central Mediterranean Sea
Silvia Becagli,Luigi Lazzara,Fabiola Fani,Christian Marchese,Rita Traversi,Mirko Severi,A. di Sarra,Damiano Sferlazzo,Salvatore Piacentino,C. Bommarito,Uri Dayan,Roberto Udisti +11 more
TL;DR: In this paper, the authors discuss existing relationships among methanesulfonate (MS−)-one of the end products of oxidation of biogenic dimethylsulfide -DMS) in the atmospheric particulate, phytoplankton biomass, and remotely-sensed activity in the central Mediterranean.

TL;DR: A year-round study of atmospheric oxidised sulphur compounds (methanesulphonic acid (MSA) and sulphate) was carried out in the east Antarctic Plateau at Dome C (75° 06′ S, 123° 20′ E, 3220m a.s.l. as discussed by the authors.

Chemical composition and physical features of summer aerosol at Terra Nova Bay and Dome C, Antarctica

TL;DR: During the 2002-2003 austral summer field season, aerosol samples were collected at a coastal and inland site and the observed agreement between nssSO4(2-) and methanesulfonate temporal profiles in the fine fraction demonstrates that biogenic emissions dominate the inland background aerosol.
