95,000 miles of U.S. coastline 25,000 miles of navigable channels All ports, rail and highways -- intermodal links Supports 13M jobs, contributes $742B to U.S. GDP 95% of foreign trade in/out of U.S. by ship 78M recreational boaters; $26B spent in FY00 for boaters Every U.S. citizen relies on the MTS: energy delivery, exports, transportation, cost-effective consumer goods, recreation, environmental protection The MARINE TRANSPORTATION SYSTEMThe Nation’s network of oceans, lakes, rivers, canals, locks and dams U.S. Coast Guard
Critical MTS Issues ’99 Report to Congress: An Assessment of the U.S. Marine Transportation System Critical MTS Issues • ECONOMY – total volume of maritime trade will more than DOUBLEin 20 years • INFRASTRUCTURE – Crumbling, undersized, aging; compromises safety • TRAFFIC – More ships, more CONGESTION • SECURITY – Port safety, Military Deployment, Readiness U.S. Coast Guard
Critical MTS Issues (cont.) • SAFETY – 3500 commercial shipping accidents annually on U.S. waterways, 6500 recreational • HAZMAT – over 50% cargo is oil or hazardous material • ENVIRONMENT – Increasing coastal stresses: recreation, development, dredging NOAA St. Petersburg Times

Container Ship Evolution *TEU – Trailer Equivalent Unit
95% by tonnage of all U.S. commerce • 45% by value (about $500 billion) • 50% is hazardous materials • Vessel size is pushing the limits of under keel clearance in many shipping channels. • Maritime Commerce is expected to double over the next 20 years

COSCO’s 9800 TEU Vessel = 4900 Trucks Traveling at 60 MPH, that’s a line of trucks stretching over 320 miles down the highway!
15,000 TEU Containership L.O.A. = 400 m (1,312 ft.) Draft = 14 m (46 ft.) BEAM = 69 m (226 ft.)
Data Needs:Critical Underkeel Clearance Issues require more accurate surveys! 1" of draft = $3M in autos $50K in cargo $100K in coal

THE CRUISE SHIP INDUSTRY GENERATED $18 BILLION IN 2000 • Up From $11B in 1997 / $15B in 1999 • Direct Receipts– goods and services, hotels, restaurants, shopping • Indirect Impacts– sales tax, gratuities
Hubbard Glacier – Yakutat Bay NOAA • Glaciers are receding beyond charted limits • Cruise ships pushing the margin for the view
NOAA Hydrographic Survey Priorities revision March, 2004 Example of Additions to “Critical Areas” • Kodiak Island, AK • Increases in commercial fishing vessel and eco-tour cruise traffic. • Majority of sounding data from 1800’s vintage. • Some areas have never been surveyed. • Area susceptible to significant tectonic changes • Shoreline areas and sounding data reported to be grossly inaccurate. Crit 2004
Additional Critical Area of 1,455 snm added to the GOM to support petroleum industry marine navigation needs
EARTHQUAKES - UPLIFT Hanning Bay fault scarp on southwest Montague Island in Prince William Sound. Ground northwest of the fault (right side of photo) was displaced upward as much as 16 feet with respect to the ground southeast of the fault during the earthquake, but both sides of the fault were uplifted with respect to sea level.
Other Depth Changes Hurricanes – rapid change Sand wave movement Sedimentation/siltation – slow changes Tectonic uplift – Alaska Subsidence – Gulf of Mexico

NOAA Hydrographic Survey Priorities • Provides a graphical representation of 500,000 snm of “Navigationally Significant” areas, prioritized by need for hydrographic survey with modern technology • Used as a base reference for scheduling hydrographic surveys • 43,000 square nautical miles (snm) of “critical” area first identified in 1994 • Priorities reevaluated and published in the National Survey Plan in November, 2000. • Priorities refined and delineated in greater detail in 2004 • 2004 edition renamed “NOAA Hydrographic Survey Priorities” (NHSP) November 2000 National Survey Plan March 2004 NOAA Hydrographic Survey Priorities
NOAA Hydrographic Survey Priorities • Other data sources for determining priorities: • NOAA Regional Navigation Managers • Pilot Associations, Port Authorities, Commercial and State or Local Government marine interests, USCG, USN, etc. • Survey Request File (SURF) • U.S. Army Corps of Engineers Waterborne Transportation Statistics • NOAA Coast Pilot • Judgment and experience of hydrographers in Coast Survey
NOAA Hydrographic Survey Priorities • Critical Area: • High commercial traffic volume • Extensive petroleum or hazardous material transport • Compelling requests from users • Vessels with low under-keel clearance • Priority One – Five Areas: • Primarily based on vintage of prior surveys and commercial traffic levels • Resurvey Areas: • Areas that require periodic resurvey with modern technology due to natural or human induced affects such as silting, shoal migration, earthquakes and slides, dumping, or changes in marine traffic levels. • (Resurvey areas are still under revision for the 2004 edition of the NHSP)
