SOA Table of Contents • Atmosphere • Circulation • Surface temperatures • Forcing of changes • Ocean • Circulation • Heat and freshwater content • Sea level • Sea Ice Cover • Extent and thickness • Surface conditions • Land • Vegetation • Water and ice • permafrost
Next SOA Topics • Atmosphere • Ocean • Sea ice • Land • Greenland ice sheet • Biology A new format will be used - a simple “report card” with back-up science papers.
Arctic Climate Observations • The SOA report reinforces that the Arctic has to be considered as a system • The Arctic Research Program from its inception has included ocean, ice, atmosphere and marine ecology as its main elements and continues to work in this way
Arctic Atmospheric Observing Network • Arctic Change Detection and System Analysis • RUSALCA • North Pacific Climate Regimes and Ecosystem Productivity • Arctic Sea Ice Thickness Observing Network
International Arctic Systems for Observing the Atmosphere Tiksi, Russia Barrow, Alaska Ny-Alesund, Svalbard Eureka, Canada Summit, Greenland Alert, Canada
Science Goals • Provide multi-decadal cloud, radiation, aerosol, meteorological and flux data • Use observations to understand atmospheric and surface processes at regional scale • Apply data to improve model parameterizations • Support calibration, algorithm development and validation for satellite observations • Serve as logistics base for diverse science observations, e.g., permafrost borehole, etc
RUSSIA USA RUSALCA RUSALCA Goals: • Observations where Arctic sea ice is reducing rapidly • Bering St. fresh water, nutrient fluxes • Regional physics and ecosystem response to change. • Improve international Arctic science collaboration • Explore the unknown Arctic with OE Russian American Long-term Census of the Arctic
A RUSALCA Goal: Gateway Fluxes via Long-term Moorings in Bering Strait NOAA, NSF, RAS will install 8 Moorings Across the Bering Strait in 2007
CF = Coastal Fish SCCF = South-Central Chukchi Fish WCF = Western Chukchi Fish NCF = Northern Chukchi Fish NCF WCF SCCF CF Demersal fish distribution Bottom Water Masses SSW BSW AW ACW • Fish community correlates reasonably well with water masses • Fish community also correlates positively with substrate type
Climate Change Scenarios in Eastern Chukchi Sea Increase in ACW conditions (fresher, warmer, less productive) • Less infauna, reduction of biomass hotspot • Probably unchanged epifauna ? • Re-distribution of fishes (expansion of south-central • Chukchi fish) • Invasion of invertebrates and fishes from Bering Sea • Longer food chains (less tight benthic-pelagic coupling)
RUSALCA Found Further North Walleye Pollock Theragra chalcogramma
Arctic Observing Network • Interagency, international effort to observe over decades, changes in the environment in the Arctic to provide stakeholders with climate, weather, research and resource information critical for the global society.
Goal: Contribute To the design Of an Arctic Observing Network Based on the SEARCH Implementation Plan and Existing Operational Networks
Developing International Science Partnerships • IPY • Arctic Regional GOOS • Arctic Observing Network (AON) and its developing international counterpart • Arctic GEOSS
NOAA Arctic Research:Coordination AON/GOOS/GEOSS Intragency International Interagency
International Polar Year: Exploration-Observations RUSALCA: Exploration of Marine Life in the Pacific-Arctic: What lives in this part of the Arctic Ocean? How will it migrate due to climate change?
International Polar Year: Arctic Observations • Causes and Impacts of Recent Changes in the Pacific Arctic (RUSALCA) • Polar Atmospheric Observatories and Field Campaigns (IASOA) • Polar Stratospheric Ozone Depletion Observations • Autonomous under-ice systems testing (AGAVE expedition, methane fluxes from the seafloor) • Unmanned Aircraft Systems (UAS)
International Polar Year: Observations • Causes and Impacts of Recent Changes in the Pacific Arctic (RUSALCA) • Polar Atmospheric Observatories and Field Campaigns (IASOA) • Polar Stratospheric Ozone Depletion Observations • Autonomous under-ice vehicles (AGAVE expedition, methane sensing) • Unmanned Aircraft Systems (UAS)

A UAS base would address the Arctic’s unique environmental threats.
International Polar Year:Prediction & Modeling • Short-term Arctic Predictability (STAP): THORPEX • Advances in Satellite Products and their Use in Numerical Weather Prediction • Arctic Climate Modeling:
International Polar Year: Data, Outreach & Decision Support • NOAA’s Data, Information, and Change Detection • Regional Integrated Science and Assessment (RISA) • National Ice Center (NIC) • Education: IPY/NSTA symposia • Association of Science and Technology Centers (IGLO PROGRAM) • Climate Change in the Arctic Ocean-Teacher Development project.

Possible Arctic Influences on Global Climate Change: • Increase of methane in the atmosphere due to a thaw in the permafrost on land and under water • Fresh water /salt water unbalances, Ocean circulation disruption • Changing albedo of the planet due to melting of sea ice and taller vegetation • Extinction or migration of many species • Rising sea level due to the melting of the Greenland Ice Sheet • Increase in severe weather 26
Melting permafrost release of greenhouse sequestered gases Changes in sea ice cover Change in planetary albedo Melting Greenland ice sheet – Rises in sea level Atmospheric Influences on the total system are profound
Sea Ice thinning is predicted to Continue Pacific Gateway
