Highlights from AGU Fall 2016 Meeting Marine Aerosols and Trace Gases Particulate - sea salt and organic matter - and gaseous - sulfur and halogen - emissions from the oceans affect the formation, number concentration, and composition of cloud condensation nuclei (CCN) and ice nucleating particles (INP), and influence the reactive chemistry, budgets, and lifetimes of climate-active gases. This session invites contributions in the general areas of (1) laboratory studies, field experiments, and satellite studies of the production, chemical characterization, and optical properties of sea spray, sea-surface micro layer composition, measurements of gaseous halogens and DMS, and aerosol photochemistry; (2) regional and global scale modeling of sea spray and ocean-derived trace gases; (3) development of innovative instrumentation relevant to air-sea aerosol/gas exchange. Contributions from recent field campaigns leading to process-level understanding of entrainment of aerosol from the upper troposphere and removal mechanisms (both dry and wet deposition) are also encouraged. Friday, 16 December 2016 Oral sessions: A54C. 4:00 PM - 6:00 PM; Room 3002 Poster sessions: A21A. 8:00 AM - 12:20 PM; Moscone South - Poster Hall

Highlights from Goldschmidt2012 Meeting Climate projections remain an important scientific goal for the earth science community. A large fraction of the uncertainty in predicting climate change lies in the uncertainties associated with feedbacks in the carbon cycle and aerosol forcing. These feedbacks are the result of land-atmosphere-ocean natural and anthropogenic interactions. Understanding those interactions is of great importance for characterizing possible future changes in the evolving Earth. While aerosols are a source of micronutrients (iron, phosphorus, nitrogen) for the ecosystems, the emission and transformation processes of many aerosols (e.g. desert dust or secondary organic aerosols of biogenic sources) can themselves be influenced by biogeochemical processes. We invite submissions on lab/field measurements, remote sensing, and modeling that lead to process-level understanding of biogeochemical land-atmosphere-ocean interactions. Interdisciplinary research on deposition of dust and volcanic particles, heterogeneous chemical/photochemical transformation of aerosols, and in-situ studies for the effects of aerosols on ocean/terrestrial biogeochemistry are welcome. The earth system models with aerosol deposition coupled to the land-ocean biogeochemistry are in their infancy. Until such models can reliably reproduce the effect of aerosol deposition on carbon cycle, it will be problematic to estimate how changes in aerosol deposition over time might have affected the evolving climate of the Earth. 11a.

With the help of Drs. Meskhidze and Elizbarashvili and financial support from the U.S. Civilian Research and Development Foundation (CRDF) on August 5, 2011 a new MS program in meteorology-climatology was launched at Ilia State University, Tbilisi, Georgia. This is the first master's program in the Southern Caucasus that will teach physical principles and possible consequences of climate change. http://www.iliauni.edu.ge/index.php?lang_id=ENG&sec_id=346&info_id=5727 |

Highlights from AGU Fall 2011 Meeting Incomplete quantification of bidirectional fluxes of trace gases and aerosols between the ocean ecosystem and the atmosphere makes it hard to separate natural from anthropogenic aerosol forcing, hampering the climate change assessments. We invite submissions on lab and field measurements, remote sensing, and modeling that lead to process-level understanding of biogeochemical ocean/atmosphere interactions. Interdisciplinary research on seasalt, primary/secondary marine organic aerosol, trace gas emission and photochemical production, deposition of dust and volcanic particles, and measurements of marine aerosol optical properties are welcome. Aerosols and Trace Gases over Marine Environment: Their Production Mechanisms, Abundance, Optical Properties, Biogeochemical Cycling and Climatic Effects TUESDAY, DECEMBER 06, 2011 Oral sessions: A24A. 4:00 PM - 6:00 PM; Room 3002 Poster sessions: A21A. 8:00 AM - 12:20 PM; Halls A-C

Highlights from AGU Fall 2010 Meeting Incomplete characterization of aerosol number concentration, size distribution and chemical composition over the oceans makes it hard to separate natural from anthropogenic aerosol forcing, and hampers the assessments of climate change. We invite submissions of lab and field observations, remote sensing, and modeling that lead to process-level understanding of the interactions between marine aerosols, clouds, precipitation, and radiation. Interdisciplinary research for the bidirectional ocean ecosystem-atmosphere flux of aerosols, e.g., sea spray generation of seasalt and primary marine organic aerosols, and secondary aerosols from ocean-emitted trace gases are particularly welcome. Marine Aerosols: Production Mechanisms, Chemical Composition, and Representation in Regional and Global Models Oral sessions: Dec 16, 2010, 8:00 – 10:00 AM Location: 3004 (Moscone West) Poster sessions: Dec 16, 2010 13:40 PM Location: Poster Hall (Moscone South)

Highlights from AGU Spring 2010 Meeting Scientists from around the world will present oral and poster sessions at this year’s American Geophysical Union (AGU) 2010 Ocean Sciences Meeting regarding ocean-aerosols interaction. The bidirectional fluxes of aerosols (e.g., sea spray generation, anthropogenic aerosols, and aerosols resulting from photochemically produced trace gases emitted from the ocean) may be of fundamental importance to understanding the Earth radiation energy budget and coastal air quality. In addition, long range of transport of aerosol into the open oceans deposits a significant amount of minerals to many nutrient deficient marine ecosystems. Land and ocean physical and biological systems that produce these aerosols can be strongly impacted by climate change, with potential important climate feedbacks. The governing processes of these phenomena are poorly understood, and our understanding and modeling are limited by availability of observational data. This session will focus on detection and quantification of the possible climate forcings and feedbacks that link global ocean ecosystems with aerosols, clouds and air quality. We invite submissions which include specific science questions and new techniques (including remote sensing, field observation, and modeling) that will lead to process-level understanding of biogeochemical ocean/atmosphere interaction. Ocean-Aerosol Interactions Oral sessions: Feb 22, 2010, 8:00 – 10:00 AM Location: PB254 Poster sessions: Feb 23, 2010 5:30 – 7:00 PM Location: Poster Hall E

Highlights from AGU Fall Meeting 2009 Scientists from around the world will present oral and poster sessions at this year’s American Geophysical Union (AGU) Fall Meeting regarding detection and quantification of the possible climate forcings and feedbacks that link ocean ecosystems with aerosols, clouds and air quality. Over the past two decades, in situ measurements, satellite remote sensing and modeling efforts have shown important biogeochemical interactions and feedbacks between the ocean and atmosphere. However, these findings have also revealed the inherent complexity of aerosol-ocean biology-cloud interactions with multiple forcings and feedbacks, influencing the direct and indirect radiative effects of aerosols and the abundance of long-lived greenhouse gases. Therefore, it is our goal to bring together both atmospheric and oceanic scientists interested in an improved quantification of these processes and their role in future projections of climate. The scope of this session is broad and covers the production, physical and chemical characterization of aerosols in marine environment as well as their direct and indirect forcings and feedbacks on climate. Results from in situ measurements, remote sensing and modeling studies are welcome. The session details and abstract are included below. Marine Biogeochemical Cycles: A Second Look at Aerosol-Cloud-Climate Feedbacks Oral sessions: Dec 18, 2009, 1:40 PM-3:40 PM 3008 (Moscone West) Poster sessions: Dec 18, 2009, 8:00 AM-12:20 PM Poster Hall (Moscone South)
