Coast Survey is the nation’s nautical chart maker
Traditional paper charts
Electronic navigational charts

NOAA charts cover U.S. coastal waters
U.S. marine transportation system:95,000 miles of coastline
25,000 miles of navigable channels
U.S. EEZ is 3.4 million square nautical miles
Office of Coast Survey
NOAA charts are the source of all U.S. nautical charts
Commercial vessels called on U.S. ports 63,000 times in 2010.
Every vessel is required to carry nautical charts.
10 million U.S. residents sailed on a cruise in 2010.
Every cruise ship must use nautical charts.

Mariners have trusted Coast Survey for over two centuries
• First science agency of the U.S., formed in 1807• Surveys 3.4 million square nautical miles• Creates and updates over 1,000 nautical charts• Speeds re-opening of ports after hurricanes and
other disasters• Develops hydrodynamic models for coastal
management• Provides global hydrographic leadership

“Seeing” the seafloor
• Deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers.
Hydrography is the branch of applied sciences that:

National Policy guides NOAA in the Arctic• Presidential Executive Order (July 2010)
– “Address environmental stewardship needs in the Arctic Ocean and adjacent coastal areas in the face of climate-induced and other environmental changes.”
– “Implement comprehensive integrated ecosystem-based coastal and marine spatial planning in the United States.”
• NOAA Arctic Vision and Strategy (February 2011)
– Enhance international & national partnerships. Share data and observational platforms.
– Advance resilient and healthy Arctic communities and economies. Improve safe navigation, oil spill response readiness, geospatial infrastructure, and climate change adaption strategies.

Preparing for new Arctic routes
Office of Coast Survey
NOAA recently updated Arctic charting priorities
• 14 new charts planned• Seeking views of
maritime interests

Chart 16161:Kotzebue Harbor and Approaches
• Based on a large survey conducted by NOAA Ship Fairweather, summer, 2011
• Published in April 2012 – 1:50,000 scale
• Previously, the largest scale chart available was 1:700,000
Office of Coast Survey
New charts are planned as data becomes available

Recon surveys in 2012• Fairweather checked
sparse soundings acquired by early U.S. Coast and Geodetic Survey field parties and by other agencies.
• The vessel traveled along a 1,500 nautical mile coastal corridor from Dutch Harbor, Alaska, to the Canadian border.

Could we respond to a major event in the Arctic?
• Improving geospatial infrastructure• Correcting meters-level positioning errors• Increasing tide, current, and water-level coverage• Updating shoreline and hydrographic data• Producing new nautical charts
NOAA must tackle substantial hydrographic, cartographic, and geospatial tasks in Alaska. These tasks include:
