NOAA and Coast Guard survey shallow channels in eastern Chesapeake Bay to update aids to navigation

By Lt j.g. Patrick Debroisse

The area of the Chesapeake Bay along the Eastern Shore of Maryland is one of our nation’s treasures. Home to unique underwater grasses, fish, and shellfish, this complex transition from river to sea is also home to millions of tons of sediment delivered annually from eroding land and streams. Recreational boaters, fisherman, and cruising vessels are keenly aware of the shifting sands and sediment deposits in these shallow waters and rely on aids to navigation (ATON) — a system of beacons and buoys — to travel safely to and from the harbors and docks along the shoreline.

U.S. Coast Guard (USCG) Aids to Navigation Team (ANT) from Crisfield, Maryland, recently requested the assistance of NOAA’s Office of Coast Survey to help identify areas where ATON were in need of repair, relocation, or removal due to the shifting sediment of these nearshore areas. Crew from NOAA research vessel Bay Hydro II and from navigation response team (NRT) 1 (homeported in Stennis, Mississippi) operated an Echoboat autonomous surface vehicle (ASV) from a USCG vessel to survey these shallow waters.

The team first visited Slaughter Creek, near Taylor’s Island, where the USCG believed sediment in the channel was shifting, requiring potential ATON relocation. The second area was in Pocomoke River, east of Smith Island, where shoaling in the already shallow channel was of concern, as well as the existence of unused ATON anchors. The ASV, equipped with side scan sonar to search for underwater objects, and a multibeam echo sounder to check the contours of the channels, surveyed both areas.

Once the survey data is processed and delivered to the USCG ANT, they can make informed decisions about ATON maintenance. Finding old ATON anchors and recycling them back into service is a potential cost savings for the USCG. NOAA and the USCG plan to operate the Echoboat ASV in this area again, surveying the waters for a possible wreck in Fishing Bay and for old ATON moorings replaced by a day shape.

As NOAA Ship Rainier underwent repairs in South Seattle, the ship’s survey launches and their crews carried out a project to update nautical charts around the Port of Everett and its approaches in Possession Sound. The boats used state-of-the-art positioning and multibeam echo sounder systems to achieve full bottom coverage of the seafloor.

The ports of Seattle, Tacoma, and Everett have experienced an increase in vessel traffic and capacity within the last decade. The Port of Everett serves as an international shipping port bringing jobs, trade, and recreational opportunities to the city. Across Possession Sound, Naval Station Everett is the homeport for five guided-missile destroyers, and two U.S. Coast Guard cutters. The data collected from this project will support additional military traffic transiting to and from Naval Base Kitsap in addition to the Washington State Ferries’ Mukilteo/Clinton ferry route, commercial and tribal fishing, and recreational boating in the area.

Some areas of the charts outside of Everett are based on data acquired between 1940 and the 1960s, a time when sonar technology did not allow acquisition of full bottom coverage. Complete multibeam coverage will provide mariners with modern, highly accurate information on shoals, rocks, and intertidal mudflat locations. During the first week of May, a team of nine Rainier crew members moved four survey launches from Lake Washington, where Rainier was docked, to Everett. The team, consisting of wardroom, survey, and deck department members, conducted 17 days of survey.

During this project, Rainier trained several individuals to become qualified hydrographers in charge and/or launch coxswains. Much of the multibeam acquisition in the Everett project was more gradual and shallow compared to the “steep and deep” coastline of Alaska that Rainier is more accustomed to seeing. This served as a perfect place for individuals to increase confidence and capability after a long winter repair period.

In addition to updating depth data, the Rainier survey team updated chart symbology information found on paper and electronic navigational charts of the area. Some examples of chart symbology include rocks, kelp beds, aids to navigation, traffic separation schemes, and other man-made and natural features. Traditionally, chart features are positioned using the ship’s 19-foot outboard skiffs. Equipped with a GPS positioning unit, the skiffs carefully approach a charted or new feature, and get as close as safely possible to determine the location and height. The Port of Everett contains many man-made shoreline features such as pilings, docks, and breakwater which are ideal for using a topographic laser to collect feature attribution.

For this project, the team used Rainier’s relatively new jet-propelled boat, RA-2, that is equipped with lidar. Using sixteen laser beams, light reflects off an object and is detected by a receiver; similar to how the sonar is used to find objects on the seafloor. Topographic laser feature attribution allows the surveyor to locate and place these features accurately with height information combined with precise positioning and orientation (roll, pitch, and yaw of the vessel) data.

The crew to gained experience and developed procedures using laser technology for feature positioning and height, which is safer for the crew than previous collection methods. Now, survey crews can collect highly accurate feature information from a distance. This experience, training, and procedure development was an important component of preparation for upcoming fieldwork in Alaska where the rocky and rugged Alaskan coastline experiences a large tidal range and contains many features that must be correctly identified and positioned. Rainier’s survey team received support on this project from NOAA’s Office of Coast Survey’s Hydrographic Systems and Technologies Branch, which provided additional training on lidar use and data processing.

Stay tuned for future Rainier survey updates as she heads north to survey Tracey Arm outside of Juneau, Alaska, and the ship’s adventures in California later this summer!

NOAA releases documentary on women’s service in the NOAA Corps

As Women’s History Month draws to a close, NOAA announces the release of Women of the NOAA Corps: Reflections from Sea and Sky, a documentary that highlights the important role women play in the NOAA Commissioned Officer Corps.

Women of the NOAA Corps is a 31-minute historical documentary on the lives and stories of ten women in the NOAA Corps service: how they came to the NOAA Corps, their motivations and challenges, and views on their service.

The documentary serves to elevate public understanding and appreciation of the NOAA Corps, particularly women’s service in the Corps, and to inspire the next generation of women in scientific service. The NOAA Corps is one of seven federal uniformed services of the United States, and NOAA Corps officers serve on the sea, on land, and in the air to support NOAA’s environmental science and stewardship mission.

The project was funded through the 2016 NOAA Preserve America Initiative Internal Funding Program.

Rear Adm. Harley Nygren (NOAA ret.) and Cmdr. Pam Chelgren-Koterba (NOAA ret.). Nygren was the first director of the NOAA Corps and penned entry for women to serve. Chelgren was the first woman to join the NOAA Corps in 1972, under Nygren’s leadership.

To recognize the successful history of NOAA ships Fairweather and Rainier, as well as the professional mariners, hydrographers, and commissioned officers who have served aboard these ships for the last 50 years, NOAA hosted a ceremony and public ship tours at the Marine Operations Center – Pacific (MOC-P) in Newport, Oregon.

The ceremony opened with the national anthem sung by Ensign Airlie Picket and HAST Amanda Finn. Capt. Keith Roberts, commanding officer, Marine Operations Center – Pacific, served as master of ceremonies introducing Representative David Gomberg, District 10 – Central Coast Oregon State Legislature, Rear Adm. Shep Smith, director, Office of Coast Survey, and Rear Adm. Nancy Hann, deputy director, Office of Marine and Aviation Operations and NOAA Corps, who all gave remarks during the ceremony.

“Today we are here to recognize a milestone in the career of the Rainier and Fairweather, who turn 50 this year.  They are the last of a generation of truly beautiful ships,” said Rear Adm. Shep Smith. “The passion, dedication, and craftsmanship of generations of engineers and deck force have kept these ships operable for 50 years and this is no small feat.”

Both ships, along with their sister ship, Mt. Mitchell, were constructed at the Jacksonville Shipyards in Florida and later christened in March of 1967. Following hydrographic tradition, the ships were named for features near their working grounds—Alaska’s Mt. Fairweather, Washington’s Mt. Rainier, and North Carolina’s Mt. Mitchell. The U.S. Coast & Geodetic Survey commissioned the Fairweather and Rainier in October of 1968 at the Pacific Marine Center in Seattle. Mt. Mitchell was launched one year earlier and, though no longer commissioned with NOAA, is still operating as a privately-owned research vessel.
