definition: Short Title: PAME Project URL: http://www.uib.no/pame/ Proposal URL: http://classic.ipy.org/development/eoi/proposal-details.php?id=71 Microbial communities, including phytoplankton, protozoa, bacteria, archaea, fungi and virus, are by far the most abundant and the most taxonomic and genetically diverse group of organisms in marine pelagic ecosystems. Biological activity, biomass, production and remineralization in these systems are essentially microbial while higher trophic levels (crustaceans, fish, and mammals) play a minor role in quantitative terms. Microorganisms are the main drivers of biogeochemical cycles and the major producers and consumers of green-house gases, and they are therefore significant players in regulating the ecosphere. In addition, they can be important sentinels of environmental change, as alterations in the structure and biomass of microbial communities can herald changes not only in pathways of nutrient and energy transfer in foodwebs, but also in biogeochemical cycles. Despite their abundance and likely importance in polar ecosystems, very little is known about the composition of polar microbial communities, their interactions and geochemical roles, or their response to environmental changes. The PAME program will focus on polar marine microorganisms and their activities; the processes that relate to these organisms and the significance of these organisms and their activity with respect to climate and global environmental change. The projects participating in PAME will target different aspects of microbial ecology in different polar areas. Projects may also encompass studies undertaken in warmer latitudes where these compliment and inform polar research. Field campaigns, logistics and research will be coordinated through PAME, and the projects will share and exchange data, samples, field opportunities, infrastructure, human and intellectual resources in order to obtain better and more complete datasets from field surveys and experimental…
