background
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
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
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 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
