Abstract submission |
Air-sea fluxes of biogeochemically active
constituents have significant impacts on global biogeochemistry and climate.
Increasing atmospheric deposition of anthropogenically-derived nutrients
(e.g., nitrogen, phosphorus, iron) to the ocean influences marine
productivity and has associated impacts on oceanic CO2 uptake, and emissions
to the atmosphere of climate active species (e.g., nitrous-oxide (N2O),
dimethyl-sulfide (DMS), marine organic compounds and halogenated species).
These oceanic emissions of reactive species and greenhouse gases influence
atmospheric chemistry and global climate, and induce potentially important
chemistry-climate feedbacks. While advances have been made by laboratory,
field, and modelling studies over the past decade, we still lack
understanding of many of the physical and biogeochemical processes linking
atmospheric deposition, nutrient availability, marine biological
productivity, and the biogeochemical cycles governing air-sea fluxes of
these climate active species. Atmospheric inputs of other toxic substances,
e.g., lead, cadmium, copper, and persistent organic pollutants, into the
ocean are also of concern.
This session will address the atmospheric deposition of nutrients and toxic
substances to the ocean, their impacts on ocean biogeochemistry, the air-sea
fluxes of climate active species and potential feedbacks to climate. We
welcome new findings from both measurement programmes and atmospheric and
oceanic models.
This session is jointly sponsored by GESAMP Working Group 38 on ‘The
Atmospheric Input of Chemicals to the Ocean’, the Surface Ocean-Lower
Atmosphere Study (SOLAS), and the International Commission on Atmospheric
Chemistry and Global Pollution (ICACGP).

M08 - Air Quality in the Changing Anthropocene
Convener: John P. Burrows (Germany)
Co-conveners: James Drummond (Canada), Melita Keywood (Australia)
In a world in which industrialisation is
proceeding apace, the world's population has now reached over 7.5 Billion,
of which more than half live in cities, air quality has become a very
significant health and quality of life issue for many people. It also
impacts on climate change. This symposium invites contributions about
measurements, models and mitigation practices for air quality and climate
change on all time and space scales. Similarly, contributions of relevance
to the evolution of stratospheric ozone in thee changing Anthropocene are
welcomed.
M09 - The Arctic in the 21st Century: A Hotbed of Global Change
Conveners: James Drummond (Canada), Paul Kushner (Canada)
The Arctic is undergoing climatic change at a
much greater rate than the rest of the planet, with potential global
consequences. In addition to natural and anthropogenic driving,
economic activity in the Arctic is also increasing which brings new
challenges regionally and geopolitically. Increased
understanding of this change requires the best measurements, the best models
and the best understanding of the science. Many of the issues involve the
interface between the various components of the Earth system (ice, snow,
ocean, atmosphere, etc.) and also frequently transcend the traditional
disciplinary boundaries. Papers are solicited concerning measurements,
models and interpretation with a special emphasis on trans-disciplinary and
interface issues affecting the Arctic and relating to Arctic
JM02 - Anthropogenic changes in Chemistry and Physics of the Atmosphere:
Evidence and Attribution Studies (IAMAS, IAVCEI, IAG)
Convener: John P. Burrows (Germany, IAMAS)
Co-Conveners: Maria Kanakidou (Greece, IAMAS), Franco Tassi (Italy, IAVCEI),
Isabelle Panet (France, IAG)
This symposium focuses on the impact of natural
emissions, such as those from volcanoes, and anthropogenic fluxes on
atmospheric composition, chemical transformation, dynamics and climate. In
this context we welcome contributions from
i) laboratory and chamber studies
ii) field measurements;
iii) satellite observations;
iv) numerical modelling;
v) scientific and socio-economic assessments.
