SUMMARY:51st Liège Colloquium on Ocean Dynamics - Polar Oceans Facing Changes
LOCATION:Liège\, Belgium
DESCRIPTION:<p>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 CO<sub>2</sub>&nbsp;uptake, among other ecosystem
  services.</p><p>The 51<sup>st</sup>&nbsp;Liège colloquium on ocean dynamic
 s will address the observation and prediction of these changes and their co
 nsequences.</p><p><span lang="EN-US">More specifically, the following topic
 s will be covered:</span></p><ul><li><strong><span lang="EN-US">Measuring a
 nthropogenic impact and pollutants.</span></strong><span lang="EN-US">&nbsp
 ;This spans from measurement of physical parameters, trace contaminants, in
 ventory of climate related gases, micro plastics measurement, bio-indicator
 s, monitoring economic activities</span></li><li><strong><span lang="EN-US"
 >Observing changes.</span></strong><span lang="EN-US">&nbsp;Remote sensing 
 is key to monitor sea ice and ice sheet shrinkage, ocean warming and freshe
 ning, changes in ocean circulation and environmental forcing. In parallel, 
 several initiatives (e.g. AMAP, SOOS, SOCCOM, ASPeCt, ANTOS, INTAROS, SAON,
  CAFF, BEPSII among others) have developed to reinforce monitoring of the p
 olar oceans and provide insights on current changes</span></li><li><strong>
 <span lang="EN-US">Assessing impacts.&nbsp;</span></strong><span lang="EN-U
 S">Anthropogenic forcing are impacting physical processes and biogeochemist
 ry but also biodiversity and foodweb functioning. Tracking changes in an ev
 olutionary perspective is challenging</span></li><li><strong><span lang="EN
 -US">Specific cryosphere-oceans interaction</span></strong><span lang="EN-U
 S">. At the interface between land and polar oceans,</span><span lang="EN-U
 S"></span><span lang="EN-GB">ocean interactions with ice sheets and sea ice
  are key in controlling ice-sheet balance, sea level rise and water mass tr
 ansformation rates</span></li><li><strong><span lang="EN-US">Enlarge our te
 mporal perspective: paleo-oceanographic changes.</span></strong><span lang=
 "EN-US">&nbsp;Ocean sediment records provide paleoclimate proxy indicators 
 of past changes. These benchmarks allow a better grasp on current changes i
 n term of level, significance and rapidity</span></li><li><strong><span lan
 g="EN-US">Predicting future changes</span></strong><span lang="EN-US">. Mod
 eling is a major tool to understand past and present changes and to predict
  future changes from a local to a global perspective. More specifically, si
 mple ocean model, ice sheet or sea ice- ocean coupled model, biogeochemical
  model,&nbsp;</span><span lang="EN-GB">dynamic energy budget, species/trait
  distribution model among others are well suited to investigate changes in 
 polar oceans.</span></li><li><strong><span lang="EN-US">Teleconnection and 
 global perspective</span></strong><span lang="EN-US">. As a result of the t
 eleconnection of polar oceans to the global ocean, changes in polar oceans 
 can propagate more globally. Assessing such impacts is critical to understa
 nd actual and future changes of the global ocean</span></li><li><strong><sp
 an lang="EN-US">Mitigation.&nbsp;</span></strong><span lang="EN-US">Several
  tools can be used to mitigate or limit the impact of some anthropogenic pr
 essures: enforcement of conservation measures, marine protected areas, sewa
 ge treatment, education and awareness raising that need to be further devel
 oped to tackle polar ocean changes.</span></li></ul><p>Further details (sub
