A\u00a0NOAA ship plying the waters off the coast often inspires public curiosity. This is especially true when boaters and others see the ship or her launches just go back and forth, back and forth, all day. It\u2019s not a surprise, then, that NOAA Ship\u00a0Rainier<\/em>\u2019s latest project\u00a0is generating questions from the areas around Protection Island and Lopez Island, Washington.
\nDon\u2019t worry, there is no problem! NOAA’s Office of Coast Survey<\/a> is collecting bathymetric data to update nautical charts that are currently displaying depth measurements acquired from surveys conducted from 1940 to 1969. Survey vessels go back and forth, in a maneuver that is similar to mowing the lawn, as they use multibeam echo sounders<\/a> to measure the depths and to \u201csee\u201d the ocean floor. If any of the vessels discover a danger to navigation \u2013 an uncharted wreck or other obstruction, for instance \u2013 Coast Survey will immediately inform the U.S. Coast Guard and the information will be relayed to ships and boaters through a Local Notice to Mariners<\/a>.

NOAA Ship Rainer<\/em> with her launches aboard<\/figcaption><\/figure>
\nRainier<\/em> is one of the NOAA ships dedicated to hydrographic surveys<\/a> for updating the nation\u2019s nautical charts and other uses. During this project, the ship is using her survey launches to conduct the majority of the survey. Rainier<\/em> has four 29-foot aluminum boats \u2013 each equipped with a high-resolution multibeam echo sounder \u2013 that they carry aboard ship. Rainier<\/em> deploys the launches in the morning to survey, and retrieves them in the evening.
\nData acquired by Rainier<\/em> and her launches will be used to update charts 18465<\/a>, 18434<\/a>,\u00a018471<\/a>, and others, as well as the corresponding electronic navigational charts. (See the full array of charts covering this and other areas, here<\/a>.) This particular hydrographic survey project, which covers approximately 22 square nautical miles in the Strait of Juan de Fuca, is part of a multi-year project to conduct modern hydrographic surveys and completely update the nautical charts of the waters from Port Angeles to Port Townsend and north to Bellingham, including the San Juan Islands.
\nThis survey project area is a critical priority for updating the charts, since it is near three high-density traffic lanes separated by shoal areas and is frequently transited by large commercial vessels traveling both north to Cherry Point and Vancouver, British Columbia and south to Tacoma and Seattle. The waterways of Puget Sound and the Strait of Juan de Fuca, which have pristine environments, are important for marine transportation, recreation, and national security and defense.
\nRainier<\/em>, with her 50-person crew, commanded by NOAA Commander Edward J. Van Den Ameele, is expected to wrap up the project by late November.
