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.
Ah, the boat is ready, the safety vests are stowed on board, the sky is blue, and the water beckons… But hold on a sec, sailor! Where is your nautical chart?
A terrific t-shirt is sold in tourist shops at some of our nation’s harbors. It has a “definition” of a nautical chart splayed across the front: “chärt, n: a nautical map that shows you what you just hit.” It’s funny… but unfortunately, too true too often.
Resolve to get your nautical chart this year and consult it before you hit something. Advancements in Coast Survey’s digital processes now allow us to review and update charts weekly, and get them to boaters’ fingertips faster − and with less expense − than was possible years ago.
So, what product is best for you? Check out the options…
Paper nautical charts, printed “on demand.” Coast Survey maintains 1,025 nautical charts and provides the digital chart images to NOAA-certified agents, who print the latest version (incorporating weekly updates) when you order it. Order from any of our print agents – several with distribution to local marine shops – that offer different papers and optional premium services.
Free PDF nautical charts. Almost all nautical charts are available for download from our map-based interactive chart catalog or the numbered list. Crop, re-size, print or display them. (Just don’t use them for navigation if you are a SOLAS vessel, since regulated vessels need charts from NOAA-certified printers.)
Free BookletCharts™. For easy printing at home, choose NOAA BookletCharts. These PDFs have the same information as the regular paper charts, but they are sliced and diced into 8 ½ x 11” pages, so you can keep them in a regular notebook. Some boaters like to slide the pages into sheet protectors to protect them from the spray.
Free raster navigational charts. The NOAA RNC® is a geo-referenced digital image of the paper chart, used in a variety of commercial electronic charting systems.
Free electronic navigational charts. The NOAA ENC® is produced from a vector database of features. It supports real-time navigation as well as collision and grounding avoidance. ENCs are used by many computer navigation programs and mobile apps, as well as ECDIS.

New certified printing agents bring buying options
It won’t be long before mariners and the boating public will have a wider choice of options and special services when they purchase NOAA paper nautical charts, thanks to NOAA’s expanded “print-on-demand” chart production and distribution system, Coast Survey officials announced on April 4. Coast Survey recently certified new print-on-demand chart printing agents, and gave them the flexibility to offer different color palettes, various papers, a cleaner margin, and a range of services.
Rear Admiral Gerd Glang and Capt. Shep Smith inspect sample charts submitted by new print agents.
NOAA has now authorized seven companies to sell NOAA’s paper nautical charts that are printed when the customer orders them — or “on demand.” The information on the charts is still maintained by NOAA, and the charts are corrected with Notices to Mariners up to the week of purchase.
“Last October, we announced that NOAA would stop using the government printing and distribution system we originally adopted in 1861,” explained Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “We asked private companies to help us transition from the government-run system to a robust and competitive market for paper nautical charts, and we are pleased with the results.”
Five companies have now joined the original “print-on-demand” distributor OceanGrafix and the more recently certified East View Geospatial. The newly certified companies are Frugal Navigator, Marine Press, Paradise Cay Publications, The Map Shop, and Williams & Heintz Map Corporation.
Glang is confident that the expansion of the print-on-demand program will lead to new options for all who purchase U.S. nautical charts. As a premium service, for example, print agents are authorized to customize charts with user-specified overlays.
“With more chart printing agents, we hope to encourage competition and ensure fully up-to-date charts are widely available. Buyers can shop around and find different types of paper, or choose between traditional or new color palettes. Our printing agents can offer delivery or in-shop service, and customers can have their navigation track lines or other information printed as overlays on their chart,” Glang pointed out.
Rear Admiral Glang certifies one of the new printing agents for NOAA’s paper nautical charts.
“All charts sold by NOAA-certified printing partners are NOAA charts and fully meet navigational requirements.”
For the last 150 years, the federal government produced nautical charts using lithographic printing presses. Although chart-making techniques advanced from the 19th century’s delicate hand-applied etchings on copper plates to a process that is now completely computer-based, the system remained based on printing large volumes of charts, then selling them from stock for years. Charts for sale were gradually more and more outdated until a new edition was printed. The print on demand system allows the changes made by Coast Survey cartographers to reach mariners much faster.
Coast Survey continues to examine applications from additional companies wishing to become certified as NOAA chart printing agents. The examination process includes testing of applicants’ sample charts, to make sure they stand up to normal onboard usage conditions.
The paper charts sold by the NOAA-certified printing agents meet carriage requirements for ships covered by Safety of Life at Sea regulations, specified in Title 33 of the Code of Federal Regulations.
Coast Survey added three more printing companies to its roster of certified agents for paper charts, bringing the total to ten companies authorized to sell NOAA nautical charts that are printed when the customer orders them ‒ or “on demand.” Companies with histories going back decades, and even centuries, support a firm foundation for the continuing production and delivery of U.S. paper nautical charts. Iver C. Weilbach & Co. A/S, which became a certified printing agent this week, is one of oldest private owned companies in the maritime industry ‒ established in 1755 in Copenhagen, Denmark. Granville Printing has provided services since 1988, and East End Blueprint has also been in business for over 25 years.
In November 2013, we introduced NOAA ENC Online – a continuous viewer for our electronic navigational charts. You can click on the web map and zoom to selected features or locations, to see the information contained in over a thousand electronic charts of NOAA-charted waters. Each zoom moves you through an ENC depiction that takes into account the ENC scale and other attributes that are encoded in the ENC, allowing features to become visible or invisible as you seamlessly zoom in and out of the data.
NOAA ENC Online is based on Esri’s Maritime Chart Server.
Now this latest release of NOAA ENC Online lets you:
- Set a shallow and deep depth contour, which changes the shading to those parameters
- Set a safety contour (In electronic charting systems, the safety contour is set based on the ship’s draft changes the depiction of rocks, wrecks and obstructions to isolated dangers depending on if the water is “safe” or “unsafe” for vessel navigation.)
- Change between S-52 simplified and S-52 traditional symbols
- Change the background colors of the display based on the S-52 color palette for different light conditions on the bridge of a ship
- Turn off certain features based on different categories such as buoys and traffic routes
NOAA ENC Online is not certified for navigation. It does NOT fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations.
