In 2015, NOAA survey ships Thomas Jefferson and Ferdinand R. Hassler are scheduled to survey nearly 1,800 square nautical miles in the U.S. coastal waters of the lower 48 states, collecting data that will update nautical charts for navigation and other uses. In Alaska, NOAA ships Fairweather and Rainier will increase their Arctic operations, planning to acquire 12,000 nautical miles of “trackline” depth measurements of the U.S. Coast Guard’s proposed shipping route. (See this NOAA article.) The ships will also conduct several “full bottom” hydrographic survey projects, acquiring data from over 2,800 square nautical miles in survey areas along the Alaskan coastline.
We are also planning several projects for our contractual private sector survey partners, and those projects will be announced after work orders are finalized.
The Office of Coast Survey will manage the surveys that measure water depths and collect ocean floor data for charting, identifying navigational hazards, informing wind farm decisions, mapping fish habitats, and assisting with coastal resilience. Check the useful story map, 2015 Hydrographic Survey projects, for the survey outlines and more information. Coast Survey will update the map as weather and operational constraints dictate.
See the story map for all 2015 in-house projects.
Briefly, this year’s NOAA survey projects include:
1. Gulf of Maine, where chart soundings in heavily trafficked and fished areas are decades old and need updating for navigational safety
2. Buzzards Bay (Massachusetts and Rhode Island), where increased use of deeper-draft double-hull barges – and possible installation of marine transmission cable routes and wind energy development — requires updated soundings
3. Rhode Island Sound, where the Bureau of Ocean Energy Management has identified a wind energy lease area
4. Approaches to Chesapeake (North Carolina), where charts of critical navigational areas need updating for navigation and to assist the Bureau of Ocean Energy Management manage windfarm activity.
5. Approaches to Charleston (South Carolina), where updated soundings will provide the correct under-keel clearance information for the expected transit of larger and deeper-draft ships
6. Approaches to Savannah (Georgia), where the Savannah Harbor Expansion Project will increase the authorized depth of the harbor from 42 to 47 feet and updated soundings will provide the correct under-keel clearance information for the expected transit of larger and deeper-draft ships
7. Chatham Strait (Alaska), where charts need to be updated for cruise liners, ferries, Coast Guard cutters, Navy vessels, tugs, and barges that use this waterway on a regular basis or when avoiding storms in the Gulf of Alaska
8. Approaches to Kotzebue (Alaska), where deep-draft vessels have their cargo lightered to shore by shallow draft barges
9. Point Hope (Alaska), where shipping traffic is increasing due to receding ice but charted soundings are sparse and date back to the 1960s
10. West Prince of Wales Island (Alaska), where updated charts are needed by smaller vessels that use Televak Narrows as an alternate passage during foul weather
11. Shumagin Islands (Alaska), where Coast Survey needs data to create a new, larger scale, nautical chart
12. Port Clarence (Alaska), where Coast Survey needs data to create a new, larger scale, nautical chart
13. South Arctic Reconnaissance Route, where trackline data will assist consideration of the U.S. Coast Guard’s proposed Bering Strait Port Access Route Study
14. North Coast of Kodiak Island (Alaska), where we need to update charts for Kodiak’s large fishing fleet and increasing levels of passenger vessel traffic
There are literally millions of pieces of data on nautical charts. How do cartographers determine which data to put on the charts? Two Coast Survey cartographers, Paul Gionis and Lance Roddy, explained some of the processes, protocols, and NOAA charting requirements to participants at the Florida Artificial Reef Summit earlier this month. (See the archived video of their presentation, starting at 55:40.) Among their many duties, these cartographers are responsible for vetting artificial reef public notices and permits from the U.S. Army Corps of Engineers, and for acquiring source data from the state and county reef coordinators.
By explaining the nautical chart aspects of planning, creating, and maintaining fish havens, they hoped to smooth out the permitting and charting phases.
(By the way, in case you’re wondering what we mean by “fish haven,” Coast Survey’s Nautical Chart Manual defines them as “artificial shelters constructed of rocks, rubble, boxcars, boats, concrete, special designed precast structures to enhance fish habitats, remnants of oil well structures, etc., that are placed on the sea floor to attract fish. Fish havens are often located near fishing ports or major coastal inlets and are usually considered hazards to shipping. Constructed of rigid material and projecting above the bottom, they can impede surface navigation and therefore represent an important feature for charting.”)
Permits issued by the Army Corps of Engineers are the sole source for classifying obstructions as artificial reefs and fish havens for charting purposes. Specific essential information needs to be provided for charting the areas.
- Cartographers need accurate geographic coordinates and dimensions, and the “authorized minimum clearance” (safe vessel clearance) for each distinct reef boundary.
- Importantly, the designated area cannot conflict with charted features. For instance, we cannot designate artificial reefs or fish havens in safety fairways, restricted areas, anchorages, or entrance channels. It almost goes without saying that we also don’t want to place reefs in missile test areas, or areas with pipelines, cables, or unexploded ordnance.
- The cartographers must receive notice of deployment (telling us that construction has begun).
A good example of how Coast Survey works on charting artificial reefs is the initial reef proposal for Port Everglades chart 11466. The initial proposal designated a minimum clearance of 7 feet – which would prevent a mariner from transiting the area even though the water is very deep. The proposed reef area also conflicted with two established anchorages for commercial ships waiting to enter the port.
Initial reef proposal
After working with the Corps of Engineers and project planners, Coast Survey was able to split the area and chart three separate bands with progressively deeper minimum depths, from seven feet to 60 feet of clearance. They also avoided overlap with the charted anchorages. The solution prevented navigation conflicts and protected the artificial reef.
Charted fish havens were banded by progressive depths, and excluded anchorages.
The cartographers appreciated the chance to talk directly to Florida’s artificial reef community. “Events like these provide an expansive avenue to articulate Coast Survey requirements for promoting safe and efficient navigation,” Gionis points out.
Coast Survey’s navigation manager for Florida, Mike Henderson, is our charting representative on the ground in that state, and is available to work on future projects as well as answer charting inquiries in general.
NOAA’s Office of Coast Survey enters 2015 with a leadership team that is ready to transform the nation’s hydrographic data acquisition and maintenance program, making coastal data more easily accessible for digital applications that include navigation and coastal planning. We thought you might like to know who those leaders are…
Director, Coast Survey: Rear Admiral Gerd F. Glang
Rear Adm. Glang was appointed as director of Coast Survey in August 2012. A NOAA Corps officer since 1989, Glang is a professional mariner, specializing in hydrographic surveying and seafloor mapping sciences. He has served aboard four NOAA ships, working in the waters of all U.S. coasts, from the largely uncharted coastal waters of Alaska’s southwest peninsula to the South Pacific. He was commanding officer of NOAA Ship Whiting in 1999, when the ship responded to the seafloor search for John F. Kennedy, Jr.’s, downed aircraft. Just three months later, he led Whiting to the first discovery of the seafloor debris fields from Egypt Air Flight 990. Ashore, Glang has led NOAA work in hydrography, cartography, and planning. A 1984 graduate of the State University of New York Maritime College with a bachelor’s degree in engineering, Glang also received a graduate certificate in ocean mapping from the University of New Hampshire Center for Coastal and Ocean Mapping, and is a graduate of the Harvard Kennedy School Senior Executive Fellows program.

One of the best things about this time of year is creating a holiday greeting for our friends around the world. Sometimes we take a serious look at the past year, and other times we have some fun with technology. This year, we dove deep into whimsy, with a parody of the lovely traditional poem, “A Visit from St. Nicholas,” by Clement Clarke Moore.
We hope this lighthearted greeting adds a bit of cheer to the season, as we extend our sincere wishes for a safe new year across the world’s oceans. THANK YOU to all who contribute to that effort.
A NOAA 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’s not a surprise, then, that NOAA Ship Rainier’s latest project is generating questions from the areas around Protection Island and Lopez Island, Washington.
Don’t worry, there is no problem! NOAA’s Office of Coast Survey 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 to measure the depths and to “see” the ocean floor. If any of the vessels discover a danger to navigation – an uncharted wreck or other obstruction, for instance – 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.
NOAA Ship Rainer with her launches aboard
Rainier is one of the NOAA ships dedicated to hydrographic surveys for updating the nation’s nautical charts and other uses. During this project, the ship is using her survey launches to conduct the majority of the survey. Rainier has four 29-foot aluminum boats – each equipped with a high-resolution multibeam echo sounder – that they carry aboard ship. Rainier deploys the launches in the morning to survey, and retrieves them in the evening.
Data acquired by Rainier and her launches will be used to update charts 18465, 18434, 18471, and others, as well as the corresponding electronic navigational charts. (See the full array of charts covering this and other areas, here.) 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.
This 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.
Rainier, with her 50-person crew, commanded by NOAA Commander Edward J. Van Den Ameele, is expected to wrap up the project by late November.
NOAA today announced that Lake Assault Boats of Superior, Wisconsin, will build two small vessels for the Office of Coast Survey’s navigation response program, part of a plan to eventually replace all six of the program’s small survey boats. The combined cost of both 28-foot vessels is $538,200.
“All of the navigation response team survey boats are nearing or have exceeded their designed service life,” said Russ Proctor, division chief of Coast Survey’s Navigation Services Division. “A phased program to replace the navigation response team boats over the next three to five years will help NOAA maintain the program’s crucial capacity for inshore surveys and rapid response in emergencies.”
The navigation response team (NRT) boats, which accommodate three-person crews, carry high-tech multibeam echo sounders and side scan sonar to conduct hydrographic surveys in critical navigation areas. The surveys collect data to update nautical charts, and search for underwater debris or shoaling that could pose a danger to navigation — especially after hurricanes or other national emergencies.
“The modernization of the NRT fleet will continue to ensure reliable and rapid deployments to ports that need chart updates and assistance with recovery after severe weather events, even as it helps NOAA hold down costs,” Proctor said.
Coast Survey is phasing the retirement of its current fleet of NRT vessels, prioritizing the replacement of boats experiencing the highest escalating maintenance costs. Coast Survey expects delivery of the first two boats in April 2015.
The six navigation response teams are placed strategically around the country, and each boat can be transported over land. In the past three years, underwater searches by NRTs have helped to speed the resumption of maritime commerce following Hurricane Isaac (in Port Fourchon, Louisiana); Sandy (in the Port of New York / New Jersey, and in Delaware Bay); and the 2011 tsunami (Crescent City and Santa Cruz, California). An NRT also assisted the National Park Service in re-establishing safe navigation and docking at the Statue of Liberty after Sandy, and surveyed the Potomac River security zone in preparation for the 2013 Presidential Inaugural.
Nautical chart data acquired by the navigation response teams supplement hydrographic surveys conducted by NOAA ships Rainier, Fairweather, Thomas Jefferson, Ferdinand R. Hassler, and research vessel Bay Hydro II, as well as private survey companies under contract to NOAA.
Escorted by harbor police after Hurricane Isaac, the Coast Survey navigation response team had to skirt downed utility poles and hanging wires on closed Hwy 1, as they made their way from Lafayette to Port Fourchon.
A navigation response team had to clear away debris on the ramp so they could survey Marcus Hook Anchorage on the Delaware River in Sandy’s aftermath.
NOAA has issued a new nautical chart for the Delong Mountain Terminal, a shallow draft port servicing the Red Dog Mine, on the western coast of Alaska in the Arctic. New chart 16145 fills in historically sparse depth measurements, using new survey data recently acquired specifically for this chart.
“This chart is important to the Arctic economy, giving navigational intelligence for the vessels shipping zinc and lead from Red Dog Mine, one of the world’s largest producer of zinc concentrate,” explained Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “The new chart offers vastly more navigational information than the only other available chart of the area.”
The Delong Mountain Terminal is a shallow draft port servicing the Red Dog Mine, which is located about 50 miles inland. The terminal uses self-loading barges to ferry the ore concentrates to the deep draft ships anchored several miles offshore.
“The shipping season from the terminal only lasts about 100 days, so shipping efficiency is vital,” Glang points out. “This chart will help to improve those maritime efficiencies, as well as safety.”
Previously, the only official nautical chart available to transit the near shore area was the 1:700,000 scale chart 16005, which shows one depth measurement within three nautical miles of the approach to Delong Mountain Terminal. New NOAA chart 16145 offers a much more usable 1:40,000 scale coverage, with updated shoreline measurements and newly acquired hydrographic information. It shows dozens of depth measurements in the approach to the terminal, representative of thousands of soundings, to give the mariner accurate depths for navigation.
This is NOAA’s third new Arctic chart issued in the past three years. Chart 16161 (ENC US5AK97) for Alaska’s Kotzebue Harbor were issued in 2012, and chart 16190 (ENCs US4AK8D and US5AK8D) for Bering Strait North were issued in 2013.
