Transcript Alaska Ocean Observing System

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
