What better way to recognize National Maritime Day than to spend a day at the Port of Baltimore talking with the public about NOAA’s hydrographic survey work. Coast Survey’s research vessel Bay Hydro II, moored at pier 13 Canton Marine Terminal across from the NS Savannah, participated in the Port of Baltimore’s National Maritime Day celebration on Sunday, May 17.
A great cross-section of visitors came on board throughout the day. From students and families with small children to retired Navy sonar operators, there was no shortage of enthusiastic people to talk to.
“I was really impressed that so many people made the trek all the way out to the industrial sector in order to see the event.” said, Lt.j.g. Bart Buesseler, the vessel’s officer in charge. “You could look out from the pier and see container ships loading and unloading, and activity happening all around. We weren’t sure what to expect going in, but were very happy we made the trip. It was great!”
By the end of the day, over 215 people came aboard the Bay Hydro II. A great turnout for a quick visit to Charm City.

The U.S. Coast Pilot, the supplement to raster navigational charts (NOAA RNC®) and electronic navigational charts (NOAA ENC®), now provides geotagged reference points. A geotag is simply geographical location information assigned to a type of media. In this case, a geotag conveniently assists mariners with landmark positions and displays the associated nautical chart inset in the HTML version of Coast Pilot. Currently, 75 percent of the nine Coast Pilot volumes have been geotagged, with more points available each week to the mariner. Coast Pilot is updated and available for download weekly, and can easily be used on mobile devices such as smart phones and tablets. To access the geotags, select a Coast Pilot book and click the HTML hyperlink adjacent to each individual chapter of the book.
Access to the HTML version of Coast Pilot, where the geotags are located, can be found within each Coast Pilot Book webpage. This image shows the location of the HTML link for Coast Pilot Book 2.
Geotagged places will appear in bold green within the HTML version of the chapters.

Also conveniently available to the mariner in the HTML version of Coast Pilot is the Code of Federal Regulations (text highlighted in dark blue) and the entire nautical chart (chart heading of each paragraph in royal blue). The geotagged Coast Pilot project is a collaborative effort between Coast Survey and the USGS Geographic Names Information System (GNIS). The GNIS is the official database of geographic names used by the federal government as well as information regarding specific geographical positions. As digital cartography evolves, having geotagged products opens up the door for potential future uses.

NOAA’s Office of Coast Survey has added a wide range of publications to our Historical Map and Chart Collection. The collection of publications consists of annual reports, catalogs, United States Coast Pilot, Notes on the Coast, and special reports.
The collection contains over 35,000 documents from the earliest days of the U.S. Coast Survey.
- Annual Reports are yearly publications, from 1837 to 1965, that detail the many scientific and technological activities of Coast Survey.
- Aeronautical charts, U.S. nautical charts, charts of the Philippines, and the old U.S. Lake Survey charts are detailed in Catalogs.
- The Coast Pilot collection carries two centuries of volumes, from a 1796 version of the American Coast Pilot, through the 1800s and 1900s, until the 2012 versions of the U.S. Coast Pilot.
- Written in 1861 by the Coast Survey while Superintendent Alexander Bache served on the Blockade Strategy Board, Notes on the Coast were instrumental in the Union naval strategy during the Civil War.
- When geodetic, hydrographic, geophysical, and oceanographic methods were hard to find in annual reports, over 400 Special Reports, issued between 1898 and 1956, made the information easier to disseminate.
These publications provide context to the tens of thousands of maps and charts in the collection. Use the “Search Images” and “Search Publications” pages to explore the historic documents.
As an example, consider the great naturalist John Muir, whose 179th birthday is this month. He was a guide and artist on the Survey of the 39th Parallel across the Great Basin of Nevada and Utah from 1874 to 1877.
One result emerges: the 1875 Annual Report. This report notes, on page 62, that John Muir recorded the geological and botanical characteristics of Mount Shasta in Northern California. A “related maps” option, showing maps and other images mentioned in the publication, will be to the left of this result. In this case, the related maps include a map titled “Sketch Showing the Progress of the Survey on the Atlantic Gulf of Mexico and Pacific Coast of the United States with Sub Sketch Showing the Progress on the Pacific Coast.” This particular map was continually updated as new areas were surveyed and discovered. 1875 was the first year that Mt. Shasta was recorded on it.
You can also use the information from an image to locate a publication. This month marks the 99th anniversary of the 1906 San Francisco earthquake. Using Search Images on the Historical Map and Chart Collection:
Since this map is from 1907 and there are no images from 1906, assume findings after the earthquakes were not published until 1907.
- Search publications for the Annual Report of 1907.
- When the report is opened, use the “Ctrl+F” search function (press Ctrl & F together)
- Type California in the search bar that appears at the top right.
- California will be highlighted every time it is stated in the document.
On page 67, there is a section entitled “Earth Movements in the California Earthquake of 1906.” This section ‒ that highlights new vs. old triangulation, and the permanent displacements of the areas affected ‒ states, “…the effects of the earthquake of April 18, 1906, indicated that there had been relative displacements of the earth’s surface from 2 meters (7 feet) to 6 meters (20 feet) at various points near the great fault accompanying the earthquake.”
The tables indicate the permanent displacements of various points caused by the earthquake of 1906. These permanent displacements were determined by comparing the positions of identical points upon the earth’s surface as determined by triangulation before and after the earthquakes in question. (Discover how the U.S. Coast and Geodetic Survey aided the recovery of the San Francisco earthquakes of 1906 by reading the 1907 Annual Report.)
The Historical Map and Chart Collection documents Coast Survey’s discoveries throughout history. Make your own discoveries in the collection, and let us know if you have any comments, questions, or concerns.

For four weeks in February, NOAA’s Office of Coast Survey offers formal hydrographic training to newly hired survey technicians and physical scientists, using the beautiful campus at the United States Coast Guard Training Center in Yorktown, Virginia. This year, dozens of NOAA employees and others took the extensive training, covering everything from acoustics and statistics to the processing of hydrographic survey data within the CARIS software package.
Two dozen people attended in person. They came from a wide range of duty assignments: NOAA ships Rainier, Fairweather, Thomas Jefferson, Pisces, and Oscar Dyson; Coast Survey’s R/V Bay Hydro II, Navigation Response Team 1, and the Atlantic Hydrographic Branch; NOAA’s National Geospatial Data Center; and the Washington State Energy Office. In addition, we had “virtual” attendance from the NOAA ships as well as from the Olympic Coast National Marine Sanctuary, the Integrated Ocean and Coastal Mapping Center, Washington State Energy Office, and United States Coast Guard District 17.

During the last two weeks, we experienced a severe winter storm. The training facility and the surrounding roads and schools closed – but we still held classes, even though some of the commuting students had to join the ranks of the remote attendees.
Training class participants enjoy a mobile demonstration of the POS MV.
First on the agenda, attendees received on-the-job training on board R/V Bay Hydro II, thanks to the officer-in-charge, Lt.j.g. Bart Buesseler, and physical scientist technician Rob Mowery. Students also set up a horizontal control base station, performed leveling runs, simulated shoreline feature acquisition and calibrated an Applanix POS MV system. Capt. Shep Smith, Lt. Cmdr. Olivia Hauser, Lt. Cmdr. Michael Gonsalves, physical scientist Glen Rice, and others offered their expertise on a variety of topics, including statistics and the organizational structure of Coast Survey.
Students learned about field operations and sonar theory, with classes offered by Lt. Megan Guberski from the NOAA Ship Thomas Jefferson, physical scientist Matt Wilson from Coast Survey’s Atlantic Hydrographic Branch, and physical scientist Mashkoor Malik from Coast Survey’s Hydrographic Systems and Technology Programs. Lt.j.g. Matthew Forrest from NOAA Ship Rainier, and Keith Brkich and David Wolcott from NOAA’s Center for Operational Oceanographic Products and Services covered vertical control and tidal theory.
We also appreciated the participation from CARIS’ Josh Mode and Tami Beduhn, as they explained the CARIS processing workflow.
To cap off the training, Rear Admiral Gerd Glang, director of Coast Survey, talked about the future of hydrography and – importantly – awarded training completion certificates to the students.

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
