IAGC - International Association of GeoChemistry
Biogeochemistry Working Group


Symposia organized by the Biogeochemistry Working Group are the proud continuation of the tradition of the BIOGEOMON series of meetings, which were started by the Czech Geological Survey (Prague) in 1987 as GEOMON. The meeting was renamed BIOGEOMON in 1992 to emphasize the biogeochemical scope and research that was represented. There have been well attended BIOGEOMON symposia in both North America and Europe since that time, and most recently the IAGC has formed a new Working Group on Biogeochemistry with the BIOGEOMON symposium as its central focus. Supporting the Working Group on Biogeochemistry is an exciting new direction for IAGC that will provide important new connections and possibilities for members of the five existing Working Groups.


The symposium focused on biogeochemistry in an era of global change. Long-term trends in ecosystem functioning and stoichiometry of biogeochemical processes in upland and wetland soils were emphasized, along with catchment monitoring/modelling, and translocations of nutrients, micronutrients and trace metals in forest ecosystems, grasslands and extreme environments.

    BIOGEOMON 2014

    The focus of BIOGEOMON is on the biogeochemistry of forest and natural ecosystems as
    influenced by anthropogenic and environmental factors. We invite empirical and modeling studies
    on fluxes and processes related to the turnover of major and trace elements at the ecosystem,
    watershed, landscape, and global scale.

    1) Long term trends in the functioning of ecosystems
    2) Environmental controls on fluxes and processes in ecosystems
    3) Fluxes between the atmosphere and ecosystems
    4) Below ground turnover of C and nutrients in forest soils
    5) Linking biodiversity and biogeochemistry
    6) Biogeochemistry of wetlands
    7) Dissolved organic matter in ecosystems and at the interface to hydrosphere
    8) Trace element biogeochemistry
    9) Critical unknowns in the cycling of P in forest and wetland ecosystems
    10) Links between the N cycle and other elements
    11) Weathering and chemical processes as keys to ecosystem functioning
    12) Restoration and rehabilitation of ecosystems

    BIOGEOMON 2012

    BIOGEOMON 2012 hosted over 200 scientists from 18 countries. The week included 20 invited speakers, more than 120 contributed talks and 90 poster presentations. The six conference plenaries emphasized the use of time-series data, either empirical, experimental, or modeled, to define the trajectory of our past environments and project ecosystem behavior into the future. Conference research themes included: long-term integrated monitoring and modeling; biosphere-atmosphere interactions and exchanges: gases and aerosols; the role of extreme events in ecosystem biogeochemistry; linkages among biogeochemical cycles; critical unknowns in nitrogen dynamics and reactive N; biogeochemistry of peatlands; carbon cycling in well-drained forested soils; carbon cycling in poorly-drained soils; experimental manipulations of ecosystems; trace element biogeochemistry and ecosystem impact; applications of isotopes and tracers; bio-energy production impacts in forested systems; the role of biogeochemistry in ecosystem restoration and rehabilitation; and ecosystem management and ecosystem services.

    Other highlights of the week included a copious lobster banquet where participants were serenaded by Noel Paul Stookey (of Peter, Paul and Mary fame), and a mid-week day of field trips to various places of scientific and social interest in the stunning Penobscot Bay region. In addition, attendees were honored to hear an inspiring closing keynote address by Senator George J Mitchell, the former United States Senate majority leader from Maine who was instrumental in the reauthorization of the US Clean Air Act in 1990, and played a leading role in peace negotiations in both Northern Ireland and the Middle East. Overall the week provided an excellent opportunity to be challenged by presentations on cutting-edge ecosystem science, to connect and reconnect with friends and colleagues in this highly international community, and to enjoy the beauty and hospitality of coastal Maine. This highly successful event was skillfully organized by an energetic team led by Steven Norton, Ivan Fernandez and Tiffany Wilson from the University of Maine. Plans are already underway to hold the next BIOGEOMON in Bayreuth, Germany.
