Summary: Sea salt aerosol particles are abundant in the atmosphere and have significant impacts on global radiative balance. However, laboratory studies on these particles often neglect the losses of solutes to the gas phase, which can lead to misinterpretation of data and errors in air quality or climate models predictions.

Summary: Studies have shown that submicron particulates can be transferred into sea spray aerosol, potentially affecting its cloud seeding ability. This research measured bulk and sea surface microlayer submicron particulates during phytoplankton blooms to understand the influence of biological and physicochemical processes on their distribution. The results suggest that the microbial loop controls the contribution of biologically related particulate populations, while bubble scavenging is vital for enrichment of particulates in the sea surface microlayer.

Summary: This study focuses on estimating dry marine aerosol surface area using bulk optical measurements. Two field campaigns were conducted to evaluate the estimation methods. The results show that the approximation of dry aerosol surface area based on the angstrom ngstrom exponent is valid under certain conditions, but caution is needed for different distributions. The study also proposes new lidar conversion parameters applicable to marine aerosol in the Southern Ocean.

Summary: The oceans contribute to aerosol particles in the atmosphere through sea spray aerosol (SSA) production and the emission of gases that condense to form secondary marine aerosol (SMA). These aerosol emissions include salt particles, sulfate particles, and organic components. SSA particles are mainly formed from bubbles as film drops, while SMA particles come from marine biogenic gas emissions. The impact of ocean-derived particles on climate varies by region, and efforts to quantify global SSA and SMA emissions rely on global models with limited field measurements.

Summary: The production of marine aerosols is influenced by wind speed, particularly in the Southern Ocean, where enhanced aerosol concentrations as a result of surface cooling reduce near-surface westerly jet, thus decreasing aerosol production. Research indicates that there is a feedback mechanism between the atmosphere and ocean that partially regulates the production of sea spray aerosol.

Summary: This study characterizes the composition of single-particle aerosols collected during the ORACLES and CLARIFY-2017 campaigns. The study focuses on aged biomass burning aerosol and its interaction with the marine boundary layer, as well as the influence of biomass burning air on marine aerosol. The results suggest that atmospheric processes such as photolysis, oxidation, and cloud processing play a key role in the composition and morphology of aged biomass burning aerosols.

Summary: INPs have a significant impact on cloud properties over oceans. Recent studies show that marine INPs come from two classes of organic matter in SSAs, yet current parameterizations may mask specific trends. This paper proposes a new parameterization based on field study results to better understand the connection between ocean biology and marine INP abundance.

Summary: When small bubbles rupture in contaminated water, the resulting liquid jet breaks up into droplets that can release solid particles into the air. It has previously been thought that only small particles could be transported into the top jet drop, but this study shows that larger particles can also be transported and have a greater impact. Through experiments and simulations, the researchers identify the location of the liquid that forms the top jet drop and explain how interfacial rearrangement, bubble and particle size, and particle distribution contribute to particle enrichment.

Summary: The effects of atmospheric aging on single-particle nascent sea spray aerosol (nSSA) physicochemical properties are investigated in this study. The aged SSA showed an increase in the organic mass fraction with decreasing particle sizes, and aging further increased the organic mass fraction. This could be attributed to new particle formation and oxidation of volatile organic compounds. The hygroscopicity of aged SSA core-shells increased due to the presence of more oxygenated organic species. Overall, the results suggest that atmospheric aging significantly influences the nSSA physicochemical properties.

Summary: This study provides a quantitative assessment of the enrichment of dissolved saccharides in persistent whitecap foam and compares it to the sea surface microlayer (SSML). The results show that saccharides become more enriched in foam than in SSML during phytoplankton blooms, indicating a higher enrichment of organic matter in sea foam. These findings help explain how marine organic matter becomes highly enriched in sea spray aerosol.

Summary: Roughly half of the human population lives near the coast, and coastal water pollution is widespread. This study found that sewage-associated bacteria can be transferred from polluted rivers to coastal waters and then return to land in the form of marine aerosol. Chemical indicators of coastal water pollution were also identified, but bacteria were found to be better tracers. These findings highlight the importance of minimizing coastal water pollution and investigating the health effects of airborne exposure.

Summary: This study presents a method to differentiate ice-nucleating particles (INPs) into contributions from dust, sea spray aerosol (SSA), and bioaerosol. Field campaign data from Bodega Bay, California, showed that bioaerosols were the primary source of INPs between -12 degrees and -20 degrees C, while dust and SSA had little impact. The study found that the current parameterizations for dust and SSA accurately predicted ambient INP concentrations, but the simulation of bioaerosol INPs needs further research.

Summary: Mineral dust and sea spray aerosols are important sources of ice-nucleating particles that influence cloud properties, with organics playing a significant role at higher temperatures. Seawater has relatively low ice-nucleating potential. Future research should focus on characterizing organic species and improving dust parameterization models.

Summary: The impact of aerosols on clouds is a significant and still uncertain aspect of the atmospheric system. This study measured cloud condensation nuclei concentrations in the Canadian Arctic and found that ultrafine particles and growth events were mainly composed of slightly hygroscopic organic vapours from the ocean, which could increase background cloud condensation nuclei concentrations at low supersaturation levels.

Summary: The oxidation of dimethyl sulfide (DMS) emitted from the surface ocean contributes to cloud formation. This study investigates whether other sulfur-containing gases from marine sources also contribute to aerosol formation. The results show that DMS, methanethiol, and benzothiazole account for the majority of sulfur emissions, with non-DMS sulfur sources playing a significant role in the pre-bloom phase. The ratio of DMS to methanethiol emissions is influenced by bacterial sulfur demand and the availability of sulfur sources in seawater.
