Background l.jpg
Background

  • 62,000 people as of 2005

  • Land areas of 197 km2

  • Ocean area (EEZ) of 426,405 km2

  • 5 volcanic islands and 2 coral atolls

  • GDP=$510 million ($5,800 per capita)

  • 93% Pacific Islander, 3% Asian, 1% White, 3% Other

  • 90% of land communally owned, economy relies heavily on US trade, grants, and jobs. Tuna canneries are bulk of the private sector

  • Unincorporated territory of the U.S. since 1900





Major environmental issues l.jpg
Major Environmental Issues

  • What is the current state of the environment?

  • Declining near-shore fisheries

  • Impact of population growth on environment

  • Impact of environment on human population

  • Climate change

  • Nitrogen loading

  • Fossil Fuels for energy


Data collection l.jpg
Data Collection

  • National Oceanic and Atmospheric Administration

    • collects air temperature, wind speed and direction, dominant swell height, tides, barometric pressure, rainfall, sea surface temperature and atmospheric CO2

    • Data are collected by one buoy about 1 mile offshore, one station in Tafuna near the airport, and the CO2 monitoring station in Tula

  • US and AS EPA

    • Water quality of river and stream runoff


Data collection10 l.jpg
Data Collection

  • AS Department of Marine and Wildlife Resources

    • Monitor coral reef health

    • Monitor near shore and offshore fish populations

    • Assess impact of marine protected areas on human and marine populations

    • Monitor human response to changes in ocean conditions

  • US National Park Service

    • Monitor coral reef health

    • Gauge interactions between terrestrial and marine habitats


Research needs l.jpg
Research Needs

  • What is the current state of the environment?

    • Ocean currents and current flow modeling, more accurate wave energy data

    • marine resources of and biological impact of submerged barrier islands and growing island Vailulu’u

  • Declining near-shore fisheries

    • relationship between hydrodynamics and larval connectivity

    • location of important sources and sinks for marine larvae

    • impact of MPA’s on reef populations

  • Impact of environment on human population

    • Tsunami inundation and flood zone mapping


Research needs12 l.jpg
Research Needs

  • Impact of population growth on environment
