Influence of warm and moist air intrusions on black carbon deposition and snowmelt in the central Arctic
In the central Arctic, warm and moist air intrusions (WAMIs) are increasingly prevalent during winter and spring, significantly affecting the near-surface energy budget. Here, we combine in situ observations from the 2019–2020 Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition with model simulations to investigate the role of WAMIs in transporting pollutants and enhancing black carbon (BC) wet deposition. S…
The seascape of VOC production and cycling in a tropical coral reef
Volatile organic compounds (VOCs) have been proposed to indicate coral reef health, but little is known about their cycling processes in coral reefs and the roles of reef components. We studied the distribution and cycling of ocean-leaving VOCs (dimethylsulfide (DMS), carbonyl sulfide (COS), CS2, dimethyl disulfide, isoprene, CH3I, CH2ClI, and bromomethanes CH2Br2 and CHBr3) across a coral reef in Mo’orea (French Polynesia) that has a fast and un…
Melt pond CO2 dynamics and fluxes with the atmosphere in the central Arctic Ocean during the summer-to-autumn transition
Melt ponds are a common feature of the Arctic sea-ice environment during summer, and they play an important role in the exchange of heat and water vapor between the ocean and the atmosphere. We report the results of a time-series study of the CO2 dynamics within melt ponds (and nearby lead) and related fluxes with the atmosphere during the summer-to-autumn transition in the central Arctic Ocean during the Multidisciplinary drifting Observatory fo…
Low ozone dry deposition rates to sea ice during the MosaiC field campaign
Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-round flux and concentration observations from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) campaign and simulations with a single-column atmospheric chemist…
