Alaska Ocean Observing System Regional association under IOOS Part of coastal GOOS Ocean component of GEOSS IPY opportunity AOOS VISION: Arctic Users - communities - subsistence users - offshore oil & gas - shipping/navigation - resource managers - climate change researchers Information products - ocean circulation models - climate change indicators - improved sea ice, fog & weather forecasts - coastal erosion prediction - real-time access to data Arctic Priorities: National Backbone 4 C-MAN stations along Arctic coast Stream flow gauges at key sites Beaufort tide gauges (also T & S) Better bathymetry & nearshore topography measurements Moored buoys along Arctic coast Network of ice-tethered buoys Continuity of RADARSAT or similar sea ice monitoring Validation/ground-truthing for Arctic conditions of natl space-based sensors Arctic Priorities: Regional Improved forecasting of sea ice & fog Cabled observatories at Barrow Canyon, Prudhoe & Mackenzie Canyon Sea gliders & AUVs for autonomous data gathering Sensors to measure sea ice thickness Aerosondes for remote observation of near-shore ice & leads & biological surveys Offshore moorings w/ice profiling sonars Radar coverage for measured ice edge & surface currents & for ice motion & mass balance measurements Ship of opportunity program Wind & wave measurements to mitigate coastal erosion & improve navigation safety Acoustic whale listening devices AOOS VISION: Bering Sea/Aleutians Users - commercial fishing - subsistence - communities - climate change research - search & rescue - resource managers Information products - ocean circulation models - sea ice & vessel icing forecasts - coastal erosion predictions - fisheries/ecosystem productivity Bering Sea/Aleutian Priorities: National Backbone Increase number of buoys & make real-time. Monitor more variables. 5 C-MAN stations along Bering coastline between Bristol Bay & Bering Strait Add tide & river gauges Several long-range HF radar surface current mappers at pulse pts in circulations & major fishing grounds Expand fisheries surveys, increase oceanic parameters measured Bering Sea/Aleutians Priorities: Regional N-S array of 5 moorings along 70m isobath Moorings across Bering Strait Set of moorings across AK Stream s of Aleutians including shelf break buoys to measure entire water column. 2-3 moorings in Unimak pass, Amukta/Samalga Pass & Amchitka Pass Expand coverage of bottom trawl surveys and BASIS project surveys Record in real-time key indicator species such as whales Ship of opportunity program to add addtl observing points Cable-linked observatories on Pribilofs & Little Diomede Island
