Size, chemical composition, morphology and evolution over the pack-ice Abstract Aerosol particles, especially in the high Arctic are still not very well represented in climate models. Particle size and number concentrations are strongly under-predicted and temporal variations of aerosol composition and size are still not very well understood, mainly due to the sparsity of observations. The main objective of this thesis is the characterization of the high Arctic summer aerosol by means of electron microscopy in order to extend the existing data set from previous expeditions by size resolved data on aerosol number, morphology and chemical composition and to gain a better understanding of the evolution of the aerosol in the atmosphere. Ambient aerosol was collected over the pack ice during the Arctic Summer Cloud and Ocean (ASCOS) campaign to the high Arctic in summer 2008. Aerosol particles were evaluated with scanning electron microscopy and subsequent digital image processing to assess particle size and morphology. More than 3900 aerosol particles from 9 sampling events were imaged with scanning electron microscopy and merged into groups of similar morphology which contributed to different degrees to the total aerosol: single particles (82%), gel particles (11%) and halo particles (7%). Single particles were observed over the whole size range with a maximum at 64 nm in diameter, gel particles appeared > 45 nm with a maximum in number at 174 nm, halo particles appeared > 75 nm with a maximum in number at 161 nm. The majority of particles showed the morphology of marine gels, no sea salt or otherwise crystalline particles were observed. Transmission electron microscopy enabled more subtle insights into particle morphology and allowed further subdivision of gel particles into aggregates, aggregates with film and mucus-like particles. Energy dispersive X-ray spectroscopy of individual particles revealed a gradual transition in the content of Na+/K+ and Ca2+/Mg2+ between particle morphologies. Single particles and aggregate particles preferentially contained Na+/K+ whereas aggregate with film particles and mucus-like particles mainly contained Ca2+/Mg2+ suggesting a connection between particle morphology and ion content. Back-trajectory analysis was used to identify aerosol sources and to understand the evolution of the aerosol as a function of the synoptic weather situation. Particle numbers, size and morphology changed with the days the air mass spent over the pack-ice. A morphological descriptor applied to gel particles showed a clear trend suggesting that the contour of the particles becomes sharper and more distinct with increased time spent over the pack-ice. For a very long time over the pack-ice, however, we observed a morphology comparable to freshly emitted particles suggesting aerosol sources over the inner pack-ice. Size resolved aerosol chemical composition measurements were utilized to investigate the inorganic composition of laboratory generated nascent sea spray aerosol particles and ambient aerosol samples collected during ASCOS. A significant enrichment of Ca2+ was observed in submicrometer particles in either case with a tendency for increasing Ca2+ enrichment with decreasing particle size. This has strong implications for the alkalinity of sea spray aerosol particles with consequences for the sulfur chemistry in the marine boundary layer, the hygroscopicity and thus the potential of sea spray aerosol particles to act as cloud condensation nuclei.

Session 9e: The future of biogeochemical cycling in the polar regions Message-ID: <1a676f83bb9847088f001d2fa981c54c@nrm.se> We would like to draw your attention to a Session 9e at Goldschmidt 2017 on "The future of biogeochemical cycling in the polar regions". The keynote speaker will be Jorien Vonk (Vrije Universiteit, Amsterdam). To invited speaker will be Andy Mitchell (Aberystwyth Univerisity, Wales) Abstract deadline is 1 April. "The Polar regions are currently experiencing a period of warming, resulting in the retreat of glaciers, an increase in the active layer depth of permafrost and a changing hydrological cycle. Decreased permafrost cover is expected to increase overall fluxes of solutes as the active layer deepens. Likewise, solute fluxes from glaciers are predicted to increase by virtue of the increased discharge as a result of a longer melt season. As highlighted in the recent 2016 Arctic Freshwater Synthesis report, the interplay between hydrology, microbiology and geochemistry in controlling the flux of inorganic and organic solutes and the downstream impacts on freshwater ecosystems is uncertain. For example, will changing environmental conditions (e.g. hydrology) influence the cycling of metals (e.g., calcium and iron) and carbon (inorganic and organic) and in turn, the microbial communities which mediate many of the chemical reactions occurring in these environments? In this session we invite contributions from geochemistry, hydrochemistry, modelling and microbiology: essentially from all researchers seeking to understand biogeochemical cycling in these special environments with the aim of promoting dialogue between often separate disciplines." The Goldschmidt conference will be held in Paris, France, 13-18 August. We hope to see many of you in Paris!

The host this time is Research Area 2 = Clouds, aerosols, turbulence and climate Sea spray aerosol and cloud droplet formation Speaker: Prof. Merete Bilde, Department of Chemistry, Aarhus University Date: Monday 27 February, 2017, 13:00–14:00 Place: Alhmannsalen, Geoscience Building The lectures will usually be streamed and saved on the Bolin Centre website. However, this time the streaming will kindly be hosted by ACES at https://connect.sunet.se/bgcatm Abstract: Sea spray aerosol is formed by oceanic wave breaking and constitutes a major source of aerosols to the atmosphere. Once emitted sea spray aerosol contributes to the formation of cloud droplets. The role of organic molecules and surfactants in this process is however unclear. This talk addresses the formation and properties of sea spray aerosol and the ability to act as cloud condensation nuclei. Results from laboratory experiments using artificial as well as real sea water will be presented and discussed.

The workshop will provide all members of the research area with the opportunity to learn more about the ongoing research within RA2, to explore possibilities for collaborations and to learn more about the possibilities for obtaining funding from the research area. In order to cover the breadth of research being conducted within the research area it is our intention that every member who wishes to present themselves and their research can do so. The workshop will include both lunch outside Högbomssalen and dinner at Fakultetsklubben in the evening after the workshop where we hope informal discussion can continue. To enable all members of the research area to participate, the workshop will consist of both 5 minute speed talks (maximum two slides) and longer presentations by invited speakers (which we will announce shortly) covering the major research topics within RA2. We expect that all who attend the workshop will take part in the speed talks. There are no hard and fast rules on what you can present in the speed talks so long as it is of interest to RA2 members - past, on-going or future research are all welcome. We hope that members will find the workshop to be a relaxing environment for sharing thoughts and ideas. Finally, we are also interested in whether members of the research area would like to present a poster. If you would like to, please indicate so in the registration form. To register for the workshop and dinner please visit this link before March 17th: https://goo.gl/forms/73uClWgzYomkAPDX2? and fill out the form (~2 minutes, 6 questions). We look forward to seeing you all on the 8th of May! Many thanks, Matt, Frida and Lars -------------- next part -------------- An HTML attachment was scrubbed...

Why the atmospheric CO2 dropped during the last glacial is a question that has been the focus of intense research over the last decades but still is not answered. In my opinion Karen Kohfled's new work on the topic presents one of the biggest breakthroughs of the last years. *Speaker:* Prof Karen Kohfeld from Simon Frasier University, Canada, and new member of the Bolin Center External Science Advisory Group. *Title:* "*Temporal evolution of mechanisms controlling ocean carbon uptake during the last glacial cycle*" *Location:* Högbomsalen *Time:* Thursday 9 March 2017, 15:00 *Abstract,* Many oceanic mechanisms have been proposed to explain the 80-100 ppm decrease in atmospheric carbon dioxide (CO2) during the last glacial cycle, between 127,000 and 18,000 years ago. However, little has been done to determine the sequential timing of processes affecting CO2 during the last glacial cycle. Here I present a new global compilation of sea-surface temperature records, combined with previously documented changes in sea ice extent and ocean circulation, to determine when the most commonly proposed mechanisms could have been important for CO2 drawdown. Our main finding is that a step-wise cooling of the polar ocean played a key role in driving decreases in atmospheric CO2 at the start of the last ice age, primarily via its impact on the southern polar ocean. Initially, the first polar cooling 115,000 years ago is linked to the initial major drawdown of 40 ppm, and an increase sea-ice extent and surface water stratification in the Southern Ocean. Importantly, changes in deep ocean circulation, stratification, or mixing did not play a major role until the second phase of CO2 drawdown at least 30,000 years after the first CO2 drawdown. This occurred ~70,000 years ago and was coincident with the first significant influences of enhanced ocean productivity due to dust. The final minimum concentrations of atmospheric CO2 during the Last Glacial Maximum resulted from the combination of physical and biological factors, including polar surface stratification, enhanced deep ocean stratification, and ocean biological feedbacks. *Karen's Bio* Dr. Kohfeld is interested in understanding natural variability and biogeochemical linkages within the ocean and climate system, in order to better assess earth system responses to anthropogenic perturbations. Her research focuses on natural and anthropogenic changes in the ocean carbon cycle, the influence of climate and land surface conditions on atmospheric dust, and assessing and adapting to extreme weather conditions in British Columbia. -- Agatha M. de Boer, Associate Professor Dept. of Geological Science and Bolin Centre for Climate Research Stockholm University, 106 91 Stockholm, Tel: +46 8 16 4730 http://people.geo.su.se/agatha/ -------------- next part -------------- An HTML attachment was scrubbed...

The host this time is Research Area 2 = Clouds, aerosols, turbulence and climate Sea spray aerosol and cloud droplet formation Speaker: Prof. Merete Bilde, Department of Chemistry, Aarhus University Date: Monday 27 February, 2017, 13:00–14:00 Place: Alhmannsalen, Geoscience Building The lectures will usually be streamed and saved on the Bolin Centre website. However, this time the streaming will kindly be hosted by ACES at https://connect.sunet.se/bgcatm Abstract: Sea spray aerosol is formed by oceanic wave breaking and constitutes a major source of aerosols to the atmosphere. Once emitted sea spray aerosol contributes to the formation of cloud droplets. The role of organic molecules and surfactants in this process is however unclear. This talk addresses the formation and properties of sea spray aerosol and the ability to act as cloud condensation nuclei. Results from laboratory experiments using artificial as well as real sea water will be presented and discussed.
