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
