Sunday, June 21, was World Hydrography Day, a day set aside to recognize the important work of hydrographers. Measuring and describing the physical features of oceans, seas, and coastal areas is essential not only to the safe navigation of the everyday mariner, but to our nation’s economic development, security and defense, scientific research, and environmental protection.
This year’s observation was particularly noteworthy for NOAA, as we honored the lost crew members of the U.S. Coast Survey Steamer Robert J. Walker, by dedicating a memorial at the Absecon Lighthouse in New Jersey.
On June 21, 1860, the Robert J. Walker was hit by a commercial schooner while transiting from Norfolk to New York after months of surveying in the Gulf of Mexico. The ship sank 12 miles offshore, as they were heading to the Absecon Lighthouse after they were hit. Coast Survey lost twenty crew members that night, and another man died from his injuries the next day, in the largest single loss of life in Coast Survey and NOAA history.

Over 35,000 conductivity, temperature, and depth profiles added to public oceanographic database
Well before the invention of the computer and the following onslaught of digital data, S.R. Ranganathan in his 1939 book, “Theory of Library Catalogue,” described in detail how a library catalog should work and be prepared. Since then, the way we develop and maintain information databases and archives has dramatically changed. The format has morphed beyond traditional books and journals to large amounts of digital data.
The Office of Coast Survey alone produces digital data on order of several terabytes a year, and much of this data is collected by NOAA hydrographic survey vessels. In order to make the data easily accessible and available to the public, it is formatted and submitted to the National Center for Environmental Information (NCEI) ocean data archive. Here, the basic principles of library cataloging apply – find the appropriate information quickly and in the location it is supposed to be stored.

Ceremony in Kodiak, Alaska, marks the deployment of NOAA ships Fairweather and Rainier
To mark the deployment of NOAA ships Fairweather and Rainier as they begin a summer of hydrographic survey projects in the Arctic, NOAA hosted a ceremony at the U.S. Coast Guard (USCG) base in Kodiak, Alaska.
The ceremony opened with a joint USCG and NOAA color guard while the national anthem was sung by retired USCG Chief Aviation Machinist Mate, Joe Symonoski. Rear Admiral Gerd Glang, director of the Office of Coast Survey, gave opening remarks.
“Characteristically, we are quite modest about the missions and accomplishments of our NOAA ships. But today, we are taking the time to recognize the planned deployment of both ships to undertake hydrographic surveys in the U.S. Arctic,” Glang said. “It is important for us because of the renewed investment NOAA is making in this region at a time when the Arctic has become more accessible to marine transportation.”

Coast Survey helps communities prepare for the 2015 Atlantic hurricane season
June 1 marks the beginning of the 2015 Atlantic hurricane season. Although NOAA projects it to be a below normal season, it doesn’t mean coastal areas will have it easy. In the wake of a hurricane, Coast Survey plays a critical role in NOAA’s response efforts. But what about before the storm? In addition to building relationships and coordinating emergency response capabilities with agencies such as U.S. Coast Guard, U.S. Army Corps of Engineers, and port authorities, Coast Survey focuses on local community preparedness meetings and outreach events throughout the month of May.
Recently, Coast Survey’s navigation manager for the central Gulf Coast, in partnership with The National Weather Service Lake Charles and the Port of Morgan City, Louisiana, conducted public preparedness forums in Lafayette, Lake Charles, and Morgan City. One meeting featured U.S. Representative Charles W. Boustany, Jr., as the speaker. Approximately 90 people attended, including the congressman’s constituents, and local, state, and federal agencies and responders. The information provided was of vital interest given the upcoming start of hurricane season and the 10th anniversary of hurricanes Katrina and Rita.

All aboard! NOAA’s Bay Hydro II opens its doors to the public at the Port of Baltimore’s National Maritime Day Event
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.

Coast Survey improves the U.S. Coast Pilot by providing geotags
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.

Coast Survey adds historical publications to online collection
by Melissa Volkert, Coast Survey communications associate
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.

Coast Survey assists pilots in efforts to “see” dredging operations on laptop displays
What do pilots see on the navigation laptop displays of their portable pilot units (PPUs) when they guide deep-draft ships to dock? Often, they aren’t seeing all that is actually out there in the navigation channel.
NOAA Coast Survey’s navigation manager Tim Osborn recently observed the problem when he accompanied one of the pilots from the New Orleans Baton Rouge Pilots Association in a ship transit on the Mississippi River.

Coast Survey helps scientists sharpen hydrographic skills
By Lt.j.g. Eric Younkin
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.

Developing products for “precision navigation”
Ports of Los Angeles and Long Beach are first up
by Capt. Richard Brennan, chief, Coast Survey Development Lab
The increased size of vessels entering U. S. ports, coupled with the diminishing margins that must be navigated with reference to the seafloor, provides NOAA with the opportunity to develop new products to support precision navigation. The ports of Los Angeles and Long Beach are testing grounds for current product development, since developing products for these ports will allow us to examine the value of precision navigation products under actual at-sea conditions. The channel leading to the Port of Long Beach has an authorized depth of 76 feet, allowing drafts of 69 feet. A major concern for this port is high sea swell conditions that can be present when ultra large crude carriers enter port. These large swells can cause vessels to pitch, which results in a significant change in their draft.
