The Arctic Ocean and the waters w est of the Antarctic Peninsula are at the forefront of global warming, whil e the rest of the polar oceans will face changes in the very near future. T he changes to face are not limited to a raise in atmospheric temperature an d modification in the freshwater budget. Increases of economic activities ( shipping, tourism, fisheries and mineral extraction), contaminants and inva sive species also put polar oceans at risk. Changes are already witnessed i n terms of ice shelves volume, wind patterns and precipitation, sea ice ext ent, ocean circulation, ocean acidification and freshening, primary product ivity, biodiversity and community structure or ecosystem functioning. As po lar oceans are key components of the Earth system, changes there will have global impacts such as sea level rise, changes in low latitudes oceanic pro ductivity, and oceanic CO2 uptake, among other ecosystem services.\nThe 51s t Liège colloquium on ocean dynamics will address the observation and predi ction of these changes and their consequences.\nMore specifically, the foll owing topics will be covered:\n\n - Measuring anthropogenic impact and poll utants. This spans from measurement of physical parameters, trace contamina nts, inventory of climate related gases, micro plastics measurement, bio-in dicators, monitoring economic activities\n - Observing changes. Remote sens ing is key to monitor sea ice and ice sheet shrinkage, ocean warming and fr eshening, changes in ocean circulation and environmental forcing. In parall el, several initiatives (e.g. AMAP, SOOS, SOCCOM, ASPeCt, ANTOS, INTAROS, S AON, CAFF, BEPSII among others) have developed to reinforce monitoring of t he polar oceans and provide insights on current changes\n - Assessing impac ts. Anthropogenic forcing are impacting physical processes and biogeochemis try but also biodiversity and foodweb functioning. Tracking changes in an e volutionary perspective is challenging\n - Specific cryosphere-oceans inter action. At the interface between land and polar oceans,ocean interactions w ith ice sheets and sea ice are key in controlling ice-sheet balance, sea le vel rise and water mass transformation rates\n - Enlarge our temporal persp ective: paleo-oceanographic changes. Ocean sediment records provide paleocl imate proxy indicators of past changes. These benchmarks allow a better gra sp on current changes in term of level, significance and rapidity\n - Predi cting future changes. Modeling is a major tool to understand past and prese nt changes and to predict future changes from a local to a global perspecti ve. More specifically, simple ocean model, ice sheet or sea ice- ocean coup led model, biogeochemical model, dynamic energy budget, species/trait distr ibution model among others are well suited to investigate changes in polar oceans.\n - Teleconnection and global perspective. As a result of the telec onnection of polar oceans to the global ocean, changes in polar oceans can propagate more globally. Assessing such impacts is critical to understand a ctual and future changes of the global ocean\n - Mitigation. Several tools can be used to mitigate or limit the impact of some anthropogenic pressures : enforcement of conservation measures, marine protected areas, sewage trea tment, education and awareness raising that need to be further developed to tackle polar ocean changes.Further details (submission, registration, dead lines, venue, ...) are available on the web site : http://labos.ulg.ac.be/g her/home/colloquium/\n X-ALT-DESC;FMTTYPE=text/html:

Polar oceans are facing profound changes. The Arctic Ocean and the water s west of the Antarctic Peninsula are at the forefront of global warming, w hile the rest of the polar oceans will face changes in the very near future . The changes to face are not limited to a raise in atmospheric temperature and modification in the freshwater budget. Increases of economic activitie s (shipping, tourism, fisheries and mineral extraction), contaminants and i nvasive species also put polar oceans at risk. Changes are already witnesse d in terms of ice shelves volume, wind patterns and precipitation, sea ice extent, ocean circulation, ocean acidification and freshening, primary prod uctivity, biodiversity and community structure or ecosystem functioning. As polar oceans are key components of the Earth system, changes there will ha ve global impacts such as sea level rise, changes in low latitudes oceanic productivity, and oceanic CO2 uptake, among other ecosystem services.

The 51st Liège colloquium on ocean dynamic s will address the observation and prediction of these changes and their co nsequences.

More specifically, the following topic s will be covered:
