چکیده
Abstract. Dimethyl sulfide (DMS), dimethylsulfoniopropionate (DMSP) and dimethyl sulfoxide (DMSO) were measured at the Boknis Eck Time Series Station (BE, Eckernförde Bay, SW Baltic Sea) during period February 2009–December 2018. Our results show considerable interannual seasonal variabilities in mixed-layer concentrations of DMS, total DMSP (DMSPt) DMSO (DMSOt). Positive correlations found between particulate (DMSPp) (DMSOp) as well DMSPt DMSOt mixed layer, suggesting a similar source for both compounds. The decreasing long-term trends, observed DMS linked to concurrent trend sum 19′-hexanoyloxyfucoxanthin 19′-butanoyloxy-fucoxanthin, which are marker pigments prymnesiophytes chrysophytes, respectively. Major inflow (MBI) events influenced distribution sulfur compounds due phytoplankton community changes, sediment might be potential bottom layer hypoxia/anoxia BE. A modified algorithm based on reproduces DMSPp : Chl ratios this study could used estimate future surface (5 m)

Revisiting optical clearing with dimethyl sulfoxide (DMSO).
Functional optical characterization of disease progression and response to therapy suffers from loss of spatial resolution and imaging depth due to scattering. Here we report on the ability of dimethyl sulfoxide (DMSO) alone to reduce the optical scattering of skin. We observed a threefold reduction in the scattering of skin with topical DMSO application. With an in vivo window chamber model, w...

متن کاملDimethyl disulfide (DMDS) and dimethyl sulfide (DMS) emissions from biomass burning in Australia
[1] We identify dimethyl disulfide (DMDS) as the major reduced sulfur-containing gas emitted from bushfires in Australia’s Northern Territory. Like dimethyl sulfide (DMS), DMDS is oxidized in the atmosphere to sulfur dioxide (SO2) and methane sulfonic acid (MSA), which are intermediates in the formation of sulfuric acid (H2SO4). The mixing ratios of DMDS and DMS were the highest we have ever de...
متن کاملDynamics of the vernal bloom in the marginal ice zone of the Barents Sea: Dimethyl sulfide and dimethylsulfoniopropionate budgets
Phytoplankton is known to be a key element in the production and eventual oceanic effiux of dimethyl suffide (DMS) to the atmosphere. We hypothesized that the alternation of Phaeocystis pouchetii and diatoms, the two major algal components of the spring bloom, would modulate the input of partictfiate organic sulfur (POS), dimethylsulfoniopropionate (DMSP), and DMS into the mixed layer of the ma...
