Geographic names disappear from charts, but not from history — #Data4Coasts   Leave a comment

by Meredith Westington, Coast Survey geographer

Good, informed decisions are often based on analyses of historic and present conditions. Researchers, decision-makers, and amateur history buffs find detailed documentation of past conditions in the thousands of Coast Survey charts, dating back to the mid-1800s, in our Historical Map and Chart Collection.

Just like present day nautical charts, historic charts contain a wealth of information about geographic features — including their names, shape, and condition. Geographic names are important locational references for today’s emergency responders, but current and historic names also convey important aspects of local people and culture, which may persist through time.

As Coast Survey’s nautical cartographers routinely apply new topographic and hydrographic data to improve decisions at-sea, a question arises about names when a geographic feature, such as an island, bay, or bayou, has changed: does the associated place name disappear when the geographic feature is no longer there, or does the local population still use the historic name to convey a shared sense of place?

Coast Survey cartographers raised this exact question after applying new shoreline information to charts covering Louisiana. When cartographers applied new shoreline data to charts 11358 and 11364 in 2011, they found that named features were no longer there (see the images below for a comparison of today’s landforms vs. the historic landforms in 1965). In early 2013, another new shoreline survey similarly affected fourteen geographic names on chart 11361. They removed these “dangling names” to reduce chart clutter, but are there new names for the areas where the features used to be?

Losing places (and their names) may mean losing important locational references. Some of these places have appeared on NOAA’s nautical charts of Louisiana since the late 1800s, so their removal raises concerns about a loss of cultural identity on the landscape. For example, Cyprien Bay was named for longtime resident Cyprien Buras. The names live on, of course, on the historic maps and charts in Coast Survey’s Historical Map and Chart Collection. Importantly, they are also retained in the lesser-known U.S. Board on Geographic Names’ federal repository of place names, the Geographic Names Information System. The system’s current and historical records make a great starting point for finding names that you can use to locate relevant historical nautical charts in the Historical Map and Chart Collection.

NOAA Coast Survey to improve “magenta line” on Intracoastal Waterway nautical charts   2 comments

The rebuilt "magenta line" will be a directional guide to help assure navigation safety.

The rebuilt “magenta line” will be a directional guide to help assure navigation safety.

The Office of Coast Survey announced today that future editions of nautical charts of the Intracoastal Waterway will be updated to include an improved “magenta line” that has historically aided navigation down the East Coast and around the Gulf Coast. Additionally, Coast Survey will change the magenta line’s function, from the perceived “recommended route” established more than a hundred years ago, to an advisory directional guide that helps prevent boaters from going astray in the maze of channels that comprise the route.

The decision comes on the heels of a year’s investigation into problems with the magenta line. In early 2013, after receiving reports of groundings by boaters who followed the line into shoals, Coast Survey started to remove the magenta line from Intracoastal Waterway nautical charts.

“We cannot deliberately include chart features that we know may pose a danger to navigation,” explained Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “The problems of the magenta line’s misplacement, which had been developing over the past seven decades, were aggravated when some boaters assumed that the line indicated a precise route through safe water – although it actually went over land, shoals, or obstructions.”

Chart 830 - 1938

This 1938 Coast Survey chart shows the Intracoastal Waterway Route after it was updated using funds from the New Deal’s Public Works Administration.

The U.S. Coast and Geodetic Survey, a NOAA predecessor agency, first installed the line on nautical charts in 1912, when the advent of motor boating produced a demand for charts of the inland waters and shallower waters along the East Coast. The magenta line on Intracoastal Waterway charts received major updates in 1935, thanks to an influx of funding from the Great Depression’s Public Works Administration projects. Charts rarely recorded updates of the magenta line in the ensuing 70 years.

Boating public wants directional guidance

In 2013, while Coast Survey cartographers were removing poorly placed lines from charts that were undergoing regularly scheduled updates, Glang ordered a cartographic review of the magenta line’s function and maintenance. Simultaneous with an internal review of the issues, Glang issued a Federal Register Notice asking for public comments. Almost 240 individuals and organizations offered comments, saying that the line helped safe navigation on the Intracoastal Waterway.

“We asked Intracoastal Waterway users to let us know if they need the route designated on nautical charts, and the response was 99.9 percent in favor of keeping it on charts,” Glang said. “Many of the commenters explained how the magenta line saved them from dangerous or costly navigation errors. They also confirmed that we need to clear up any misunderstanding about what the magenta line is – and what it isn’t.”

The internal review and public comments confirm that the magenta line needs to be removed where it poses a danger to navigation, rebuilt to avoid shoals and other dangers, and reinstated to all the Intracoastal Waterway nautical charts. Importantly, Coast Survey will add notes to the Intracoastal Waterway charts, emphasizing that vessels transiting the waterway should be aware of changing conditions and always honor aids to navigation.

Improvements will take years to fully implement

“Today’s decision to reinstate the magenta line is not a quick fix,” cautions Captain Shep Smith, chief of Coast Survey’s Marine Chart Division. “It will take at least three years to fix problems that were 70 years in the making.”

Of Coast Survey’s 1052 nautical charts, 52 depict the magenta line. As charts are rotated through the update process, Coast Survey will evaluate and update the magenta line using charted information. When no depth soundings are on the chart, the line will generally be positioned in the centerline of dredged channels and natural waterways, avoiding shoals or obstructions less than the controlling depth. When the chart data is insufficient for determining the line’s preferred route, Coast Survey will attempt to gather additional data from partner agencies and reliable crowdsourcing.

“Most of the magenta line can be re-drawn by using the charted information, and we hope to get it done by mid-2015,” Smith explains. “On the other hand, resolving discrepancies between charted information and the line will require research, and new data acquisition and processing, with support from other federal agencies.”

Resolving chart discrepancies is a longer-term challenge, Smith says, and can conceivably take up to five years, or even longer. In cases where information is lacking and the line depiction can lead to risky navigation, Coast Survey will remove the line.

Background on the Intracoastal Waterway

The Intracoastal Waterway, extending about 3,000 miles, is essentially two waterways along the Atlantic and the Gulf Coast.

The Atlantic Intracoastal Waterway (AIWW) extends 1,200 miles from Norfolk to Key West, and is home to ports, Coast Guard bases, and a dozen military facilities. Plied by tugs and barges, passenger vessels, maritime businesses and recreational boaters, the waterways consist of a series of artificial canals and natural waterways. The AIWW will be the center of Coast Survey’s initial focus.

The Atlantic Intracoastal Waterway Association estimates that the AIWW generates billions of dollars of commercial, recreational, and personal income annually. According to a 2006 report to the North Carolina Sea Grant Program, the AIWW produces $257 million in annual sales, over 4,000 jobs, $124 million in wages, $35.6 million in federal taxes and fees and $21.4 million in state taxes and fees in North Carolina. A similar survey in Georgia claims $33 million is total revenue generated by the AIWW. A study by the Florida Inland Navigation District shows $18 billion total economic output attributed to the AIWW.

The Gulf Intracoastal Waterway (GIWW) is a 1,100-mile-long shallow draft man-made protected waterway that connects ports along the Gulf of Mexico from St. Marks, Florida, to Brownsville, Texas. The Texas Department of Transportation reports that the GIWW is the nation’s third busiest inland waterway, with 91 percent of the cargo classified as petroleum and chemical related products. According to Texas A&M Transportation Institute’s Center for Ports and Waterways, 90 percent of Gulf Intracoastal Waterway barge traffic consists of petroleum products and petrochemical-related materials.

NOAA’s paper nautical charts get a needed update – literally

Paper nautical charts hold a special spot in a sailor’s heart – and in the chart table. The October announcement that the federal government will stop bulk lithographic printing of nautical charts brought some understandable angst to boaters – but fear not! NOAA may be changing the chart production process but we will NOT stop the production of paper charts. We are working with private companies to make them better: printed in brighter colors and available for fast delivery to your door. Most importantly, they are up-to-date to the moment you order it. These improved paper charts are NOAA-certified print-on-demand (POD) nautical charts, created by NOAA Coast Survey cartographers.

While the lithographic paper charts will go away in 2014, anyone can order almost* any printed NOAA chart any time, from the comfort of your home, office, or boat. Just bookmark to find the NOAA-certified chart seller who will print your chart “on demand” and ship it to you. 

The great lithographic chart tradition answered a country’s need

For more than 150 years, the traditional paper chart that we all know and love has been printed in bulk on government printing presses, using the lithographic process. Lithographs were the latest and greatest technological achievement in the early 1850s, when Coast Survey superintendent Alexander Bache ordered Coast Survey personnel to explore the potential applications of lithography for printing maps cheaply and easily. Since the charts could be printed on cheaper and far thinner paper, lithographic copies could be folded, which was strategically important as the nation prepared for Civil War.

The new lithography helped the federal government speed the production of the thousands of charts needed for the war effort. According to contemporary reports, Coast Survey organized the “lithographing” division in 1861 “in order to aid the regular copper plate printing department in supplying speedily charts for the great demand made upon the office by the existing exigencies of the naval service, and also to afford the means of printing (under due supervision) a set of descriptive memoirs and sailing directions for the coast, for the use of the naval and military commands.”

Two lithographic presses were set up in the Coast Survey office and, according to Bache in his annual report, “an aggregate of more than two thousand copies of maps and charts were printed from them” in the first year of operation. The presses were set up, Bache says, “in order to meet the call for charts from the Naval Observatory to supply national vessels.”

The impact that lithographic printing process had on chart production is measurable. In 1844, before lithography, Coast Survey made 169 copies of its nautical charts. By the end of the Civil War in 1865, we were churning out more than 50,000 copies annually, and by 1900 we had amped up to 100,000 copies a year. With 20th century improvements in the lithographic presses and processes, Coast Survey produced over 100 million maps and charts for the Allied Forces in World War II.

The lithographic printing presses in 1908 hadn't yet reached the speed and efficiency that would be needed for time of war.

Today’s digitally-produced paper chart reduces risk for maritime commerce, fishing, and recreational navigation

Coast Survey cartographers apply tens of thousands of changes to NOAA charts every year. Some changes are minor, but many are critical to safe navigation. While lithography was valuable in its day, it can take years before a new chart edition is printed with those updates. Advances in digital technology can now deliver charts that have been updated within the week.

Much of NOAA’s chart information is now delivered electronically to chart display systems, as either NOAA RNC® or NOAA ENC®, but we can also harness digital images for mariners who prefer to keep a paper chart, for primary use or for backup. This digital process gives boaters ready access to updated NOAA-certified paper charts that are printed on demand.

As of today, NOAA has agreements with two companies –  OceanGrafix and East View Geospatial, with their local partners – to print and deliver paper print-on-demand nautical charts. We are working with a dozen other companies that have expressed an interest in becoming a NOAA-certified POD partner, and we will keep the vendor list updated at

Commercial mariners can be assured that NOAA-certified POD charts meet the requirements for the mandatory carriage of nautical charts.

Whether the paper charts are printed using lithographic printing presses or after transmission of digital images, Coast Survey’s mission is and remains the same: to produce the nautical charts that protect life and property. That is a mission that never needs to be updated.

(*”Chart books” of some areas in the Great Lakes are not yet available as POD charts. Watch for updates.)

On this day in 1943, U.S. Coast and Geodetic Survey Ship HYDROGRAPHER contributes to significant Allied victory   1 comment

by Lieutenant Matt Forney and Captain Bob Pawlowski (NOAA, ret.)

July 28 marks a little-known but important milestone in our nation’s history.

On August 15, 1943, Allied forces stormed the beaches of Kiska Island, Alaska, in an attack on Japanese occupation. They found an empty island. As it happened, the Japanese Northern Army had secretly evacuated, under a cover of fog, a few weeks earlier, on July 28, thus ending the occupation of the Aleutian Islands.

Today, then, is the 70th anniversary of the last day that foreign forces occupied U.S. soil. And our Coast Survey predecessors were an important player in that event.

The U.S. Coast and Geodetic Survey was one of NOAA’s predecessor agencies. During WWII, the USC&GS sent more than a thousand civilian members and over half of its commissioned officers to the military services. (See the NOAA Central Library account, The World Wars.) Coast Surveyors served as hydrographers, artillery surveyors, cartographers, army engineers, intelligence officers, and geophysicists in all theaters of the war. Civilians, on the homefront, produced over 100 million maps and charts for the Allied forces. Eleven members of the USC&GS gave their lives during WWII.

ATTU ISLAND and KISKA ISLAND are in the Aleutian Islands, Alaska

ATTU ISLAND and KISKA ISLAND are in the Aleutian Islands, Alaska

During World War II, the Japanese Northern Army occupied Attu Island (landing there unopposed on June 7, 1942) and Kiska Island, (landing on the next day.) The Aleutian Islands were strategic, as it meant that Japan would control the North Pacific Ocean great circle route for supplies, and the U.S. feared the Japanese would turn these locations into airbases for bombing the west coast of the U.S. mainland.

On May 11, 1943, the U.S. 17th Infantry Division made an amphibious assault on the Island of Attu to retake this territory and strategic landhold. Before the Army could carry out an amphibious attack, however, they called on the men of the U.S. Coast and Geodetic Survey to conduct surveys of landings and anchorages.

The U.S. Coast and Geodetic Survey Ship Hydrographer conducted this important preemptive science to ensure the landing vessels avoided shoals and made it safely to shore. (The Hydrographer was originally built in 1930, and sailed as the USS Hydrographer after being transferred to the Navy on April 15, 1942, for the duration of World War II.)

Following the initial assault, the Hydrographer continued surveying in Massacre Bay, Attu, to identify shoals and outline transport anchorages and supply routes.

After 19 days of fighting between the Japanese Northern Army and well-supplied U.S. forces, the Japanese forces realized that all hope of rescue was lost. They made one last banzai-style assault, and hand-to-hand battle ensued. This fighting continued until almost all the Japanese soldiers were killed. After all was said and done, 549 U.S. soldiers died, and more than a thousand were injured. The Japanese lost over 2,850 men. The U.S. only took 29 prisoners alive.

Meanwhile, the USS Hydrographer was also providing transport services to Shemya, Alaska, so the U.S. could establish a bomber airstrip for retaking Kiska.

On August 13, 1943, the Hydrographer surveyed the approaches, anchorages, and landings on Kiska to support an amphibious assault to retake this territory. Two days later, Allied Forces invaded, unaware that the Japanese had completely abandoned the island on July 28, after hearing of the fall of Attu. The invasion force consisted of 34,426 Allied troops, including elements of the 7th Infantry Division, 4th Infantry Regiment, 87th Mountain Infantry Regiment, and 5,300 Canadians (mainly the 13th Canadian Infantry Brigade from the 6th Infantry Division). Support was provided by 168 aircraft and 95 ships – including the Hydrographer.

Even though the Japanese had gone, the reoccupation came with a price. Seventeen Americans and four Canadians died from friendly fire or booby traps, 50 more were wounded from friendly fire or booby traps, and an additional 130 men came down with trench foot.

The Hydrographer has successful career

In May, 1943, the Hydrographer’s commanding officer was awarded the Legion of Merit for surveying and charting the unknown and dangerous waters surrounding Attu Island during the assault and occupation of that island.

Following her successful service in Alaska, ending the last occupation by foreign forces, the Hydrographer surveyed at Guam during amphibious operations, and at many other locations throughout the Pacific Theater of Operations. The commanding officer was awarded the Bronze Star Medal.

After the war, the Hydrographer returned to USC&GS service. She spent most of the remainder of her career surveying the Atlantic and Gulf coasts before being decommissioned in 1967, after 37 years of service to the country.

NOAA observes World Hydrography Day by honoring lost crew members of the Robert J. Walker   3 comments

Today, June 21, is World Hydrography Day. Hydrographic offices in over 80 maritime nations observe this day every year, since 2005. It is our special day to tell the public what hydrography is, and how it is employed to make navigation safer. Simply, hydrography is the science we use to obtain the data needed to create nautical charts. NOAA’s 200-year history is proof positive that those charts – and therefore hydrography – are a national investment that pays off daily with navigation safety, efficiency, and coastal protection from accidents at sea.

But today’s observation of World Hydrography Day is more profound. It is personal to every person who works in or supports hydrography in the United States.

It was 153 years ago, to the day, that the U.S. Coast Survey experienced the largest single loss of life in our history. In the early morning hours of June 21, 1860, on stormy seas, the U.S. Coast Survey Steamer Robert J. Walker was hit by a commercial schooner when she was transiting from Norfolk to New York, on a hydrographic mission. The ship sank quickly, and twenty crew members died.

In 1852, W.A.K. Martin painted this picture of the Robert J. Walker. It is now at the Mariner’s Museum in Newport News, Virginia.

Today, we honored the lost crew members of the Robert J. Walker for their service to the nation.

The NOAA Ship Thomas Jefferson is currently working near where the Walker sank. They are taking a couple of hours to survey the area, with multibeam and sidescan sonar, as part of a NOAA Maritime Heritage effort to pinpoint the exact location and confirm the identity of the Walker wreck. (While NOAA nautical charts show a seafloor obstruction, we have not positively identified the Walker.) For the survey, Thomas Jefferson commanding officer Larry Krepp welcomed two “wreck experts” on board: Joyce Steinmetz, a nautical archaeology and maritime history expert from East Carolina University, and Vitad Pradith, the technical director with Coast Survey’s Navigation Response Branch.

Honoring the memory of the 20 USCS crew members who perished the morning of June 21, 1860, the Thomas Jefferson’s newest hydrographer, Ensign Eileen Pye, laid a memorial wreath on the waters above the sunken wreck of the U.S. Coast Survey Steamer Robert J. Walker.

At the same time the Thomas Jefferson was memorializing the crew at sea, NOAA employees gathered at NOAA offices in Maryland. Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey, led the ceremony and reminded the assembled group, “With leadership comes an obligation to honor these men who made the ultimate sacrifice in service to the nation.”

RDML Glang

Rear Adm. Gerd Glang noted that this year’s celebration of World Hydrography Day was “more profound,” as it was “personal to every one of us who works in or supports hydrography in the United States.”

David Moehl, a senior survey technician on the NOAA Ship Ferdinand R. Hassler, rang an historic hydrographer’s bell, once for every man who died that day, as Cheryl Oliver, the president of the U.S. Coast and Geodetic Survey Historical Society, read each man’s name.

Rear Admiral Michael Devany, director of NOAA’s Office of Marine and Aviation Operations, talked of connections. “Despite the time that has passed, today’s NOAA employees, mariner and non-mariner alike, share a unique connection with these sailors. The common heritage of love for the sea and sky bond us with the men of the Robert J. Walker regardless of time.”

“The sacrifice paid by these 20 men reminds us of the dangers intrinsic with operations at sea,” Devany said. “We cannot go back and undo the events that took the Robert J. Walker and her crew from us, but I believe they would be honored to know the work they set out to accomplish over a century and a half ago continues today by NOAA ships and the people of NOAA.”

RADM Devany

Rear Adm. Michael Devany noted that the crew of the Walker would be honored to know that their work continues today.

David Kennedy, deputy under secretary for operations at NOAA, spoke to the heart of the accident: the need to honor all federal employees. Kennedy explained that the men who died were not the scientific or naval elites: “They were the the guys working below deck.”

“At NOAA, we celebrate the science, we tout the satellites and the surveys — and, above all, we are always mindful that we are a team. The stewards and cooks and firemen from 1860, and the technicians and support staff today, are the reasons we are able to accomplish what we do.”

“The crew of the Robert J. Walker, and the people who have followed them on hundreds of thousands of hydrographic surveys since, have served the United States government in our many hours of need. Their work – your work – has improved the welfare of our people over the centuries, as our hydrographic missions improve the safety of navigation.”

“Today, we thank and publicly honor the crew of the Robert J. Walker for their service to the nation. And, in that,” Kennedy told the NOAA hydrographers, technicians, and support staff, “we honor and thank you all as well.”

David Kennedy

David Kennedy, Deputy Under Secretary for Operations, told the NOAA audience: “Today we thank and publicly honor the crew of the Robert J. Walker for their service to the nation. And, in that, we honor and thank you all as well.”

Two other federal programs are also involved in the nation’s hydrography. We were very pleased that representatives from the National Geospatial-Intelligence Agency attended the NOAA event. In a show of solidarity, the hydrographic office of the U.S. Navy held their own simultaneous ceremony at their location in Stennis, Miss.

Rear Adm. Glang also read from a letter that Admiral R.J. Papp, Commandant, U.S. Coast Guard, wrote to Dr. Kathryn Sullivan, NOAA’s acting administrator. “I want to add my tribute to the memory of the sailors who perished in that accident, ” Papp wrote. “Coast Guardsman are always saddened by the loss of life at sea and especially so when those lost were working to make the lives of other mariners safer by charting the waters of the United States.” (Read his full letter, especially for more about the history of the Walker.)

In honor of the strong ties — historical and contemporary — between NOAA and the Coast Guard, a USCG Honor Guard proudly posted and retired the colors for the ceremony.

Back in 1860, the U.S. Coast Survey never published the names of the lost crew members. However, the New York Times, on June 23, 1860, wrote about the accident and published this list.

“The following list of the missing crew has been supplied by Mr. CHARLES GIFFORD, Quartermaster on board of the Walker, to whom we are also indebted for the particulars of the collision:

Marcus (or Marquis) Buoneventa, ward-room steward.

Michael M. Lee, ship’s cook, (colored.)

There’s a fascinating story behind (literally) the painting of the Walker. See A Good Story, from the Mariners Museum blog.

UPDATE: AUG 28, 2013NOAA announced that a wreck located off the New Jersey shore has been positively identified as the Robert J. Walker. This summer, a private-public collaboration sought to find the Walker, as experts zeroed in on where the Walker was reported to have gone down. Those experts included Joyce Steinmetz, a maritime archeology student at East Carolina University, who briefed NOAA staff on government records and newspaper accounts she had unearthed in her studies. Capt. Albert Theberge (NOAA, ret.), from the NOAA Central Library, brought his research of the early years of the U.S. Coast Survey, including correspondence between various Coast Survey officials and the ship’s officers. James Delgado, director of NOAA’s Maritime Heritage program, added his expertise gathered from years of discovering and documenting wrecks. Vitad Pradith, a physical scientist with NOAA’s Office of Coast Survey, provided technical expertise in using NOAA’s multibeam and sidescan sonar systems — onboard the NOAA Ship Thomas Jefferson — to locate and image underwater structures. (Thomas Jefferson was in the area conducting post-Sandy hydrographic surveys.)

The site of the collision and location of the wreck is plotted on this nautical chart from 1852.

“Before this identification was made, the wreck was just an anonymous symbol on navigation charts,” said Rear Admiral Gerd Glang, director of Coast Survey. “Now, we can truly honor the 20 members of the crew and their final resting place. It will mark a profound sacrifice by the men who served during a remarkable time in our history.”

NOAA’s intent is not to make the wreck a sanctuary or limit diving, but to work with New Jersey’s wreck diving community to better understand the wreck and the stories it can tell.

“We want to enhance the dive experience and support the dive industry with enhanced access to this wreck,” said James Delgado, director of maritime heritage for NOAA’s Office of National Marine Sanctuaries. “New Jersey is home to some of the most accomplished wreck divers who not only understand history and wrecks, but who have also been in the forefront of wreck exploration. We look forward to working with them on the Walker.”

For more information, see the National Marine Sanctuaries report, Rediscovering the Walker.
