ThegeographyofCanadamakesitoneofthebestlocationsintheworld for cold regionatmosphericand hydrologic studies:its high latitudeand high mountains,proximity to oceans in theArcticand cold temperate zones,a broadassemblage of landscapeand vegetation,and numerous lakesand rivers.Foryears,Canadians have conducted research on cold regions,either individually or in small groups, thusaccumulating rich experienceandample expertisein the farNorth.Creation of theGlobal EnergyandWaterCycleExperiment(GEWEX),undertheauspicesofthe WorldClimateResearchProgram,providedanexternalimpetusforlar- scale collaborative research. Canada responded to this initiativeby creatingtheMackenzieGEWEXStudyorMAGSthatfocusedonthecold region.ItwasrecognizedattheearlystageofMAGSthattheatmosphere andthehydrospherearestronglylinked.Aconcertedeffortofatmospheric andhydrologicscientistsisbeneficial,ifnotessential,toasuccessfullarge research program.In thisregards,investigation conducted bya groupof scientistsandengineersofMAGSwasentirelyrelevantandtimely.This study,carriedoutbetween1994and2005,hadtheresearchobjectivesof (1)understandingandmodelingthehigh-latitudeenergyandwatercycles that playroles in the climate system,and (2)improving ourability to assess the changestoCanada ?swaterresourcesthatarisefrom climate variabilityandanthropogenicclimatechange. So vast a world region that isunderthe influence of intense and persistent coldness cannot be covered by a contingent of Canadian researchersoveradecadaltimehorizon.TheMackenzieRiverBasinand its vicinity in northwestern Canada, occupying an area of about two millionsquarekilometers,wasadoptedasthepreferredresearchlocation. It offersa wideassemblage of environments, including mountainsand plains,tundraandforests,lakesandwetlands,andwinterslandscapesof snow, ice and frost. Its climatic continentality is accompanied by pronounced external influences,notably from the Pacific Ocean.
