Arctic-SOLAS 2007 atmospheric DMS, SO2, aerosol sulfate and MSA
The database consists of hourly atmospheric DMS concentrations, daily SO2 and total sulfate concentrations and three-day concentrations of size segregated aerosol sulfate. Samples were taken on the top of the navigation bridge of the CCGS Amundsen as it cruised along Baffin Bay and the Northwest Passage. Hourly samples of DMS was obtained using a customized DMS sampler. Samples were analyzed using a gas chromatograph fitted with a sulfur chemiluminesence detector (GC-SCD) to obtain atmospheric DMS concentrations. SO2 and total aerosol samples were obtained daily using a high volume sampler fitted with a quartz microfiber filter and K2CO3 treated cellulouse filter. Size segragated aerosol samples were obtained using a highvolume sampler fitted with slotted quartz filters on a 5 stage cascade impactor run for three days each sample. Concentrations of SO2, sulfate and MSA as well as other ions from the filter papers were obtained using ion chromatography. Delta34S values of SO2 and sulfate were obtained using a continuous flow isotope ratio mass spectrometer. Delta34S is reported based on the Vienna Canyon Diablo Troillite (V-CDT) international standard.

- Purpose
-
The CLAW hypothesis states that dimethylsulfide (DMS) could produce a climate feedback mechanism by the production of sulfate that could form new aerosols and alter cloud albedo. The melting of sea ice and opening of waters in the Arctic could potentially release more DMS in the atmosphere intensifying these effects. This study aims to understand the effects of DMS and its oxidation products to aerosol formation and growth. The use of stable isotope techniques would identify the amount of SO2 and sulfate that originated from DMS oxidation. These would serve as inputs to oxidation models to better understand DMS oxidation mechanism in Arctic conditions. Also, this would be used to ascertain whether DMS emissions in the Arctic atmosphere could result in new aerosol formation.
