NOAA library blows the dust off a photo of dust clouds

By Linda Joy, NOAA Communications and External Affairs
In April 1935, George Marsh, an unassuming engineer employed by the U.S. Coast and Geodetic Survey, took a photo in the course of his work during a Texas surveying mission. Not having Facebook or other social media tools at hand, he put the photo in an album and stored it away. He could not have known that many decades later, thanks to the NOAA Library and the Internet, his photo would eventually reach millions of people around the globe.
The now famous photo captured boiling dust clouds about to swallow a homestead during the Dust Bowl’s infamous Black Sunday storm.

Coast Survey unveils easier access to wreck information

By Lucy Hick, physical scientist, Hydrographic Surveys Division

Maintaining documentation for features depicted on nautical charts is more complicated than you probably imagine. For instance, Coast Survey maintains information on more than 10,000 submerged wrecks and obstructions in U.S. coastal waters – and it just got easier for the public to access that free information.
Coast Survey uses our Automated Wreck and Obstruction Information System (AWOIS) to help plan hydrographic survey operations and to catalog the many reported wrecks and obstructions considered navigational hazards within U.S. coastal waters. The public also has access to this rich information source. Marine archaeologists and historians, fishermen, divers, salvage operators, and others in the marine community find AWOIS valuable as an historical record of selected wrecks and obstructions.

NOAA and Coast Guard release Cooperative Maritime Strategy

NOAA and the U.S. Coast Guard recently released the Cooperative Maritime Strategy developed by the two agencies. The introduction to the document, signed by Admiral Papp and Dr. Lubchenco, is a stirring testament to our shared legacy and commitment. We reprint that introduction here.
25 February 2013

We are pleased to promulgate our Nation’s first-ever Cooperative Maritime Strategy between the United States Coast Guard and the National Oceanic and Atmospheric Administration. For over 200 years, our Services have stood in partnership on maritime resilience, environmental sustainability, and scientific research. Indeed, America is a maritime nation, and the oceans, coasts, rivers and Great Lakes are the lifeblood of our economy. The maritime commons promote economic growth, advance technology, and challenge the human spirit. Our Services share a legacy and are committed to a future that honors our responsibilities as stewards of the oceans.

Coast Survey publishes new international chart for navigation between Florida and Cuba

As the nation’s nautical chartmaker, Coast Survey produces the country’s traditional paper charts for coastal waters, territorial waters, and the Great Lakes. We maintain the Print-on-Demand charts that you can purchase from OceanGraphix and East View Geospatial. We make the nation’s raster navigational charts (NOAA RNC®) and electronic navigational charts (NOAA ENC®). And the free downloadable BookletCharts. But did you know we produce international charts, too? NOAA has five international charts covering the Northeastern Pacific Ocean and the Bering Sea… and we just published our sixth, for the opposite coast.
International mariners entering U.S. waters around southwestern Florida now have a new international (INT) nautical chart to help ease their transit. The new chart, INT 4148, has the same information as Chart 11420, Havana to Tampa Bay, but the depictions are converted to the metric system. (Most U.S. charts use either feet or fathoms for depth measurements). INT charts also use some different symbology, so Coast Survey makes those modifications as well.

Chart 11420 - INT 4148 — The image on the left is a close-up of Dry Tortugas on NOAA Chart 11420. The image on the right is the same area on INT 4148. Note that converting fathoms to meters results in different contour lines for the same area.

NOAA Ship Thomas Jefferson prepared for 2013 survey season

By Ensign Brittany Anderson, Junior Officer, NOAA Ship Thomas Jefferson
After a quiet winter at home port, the NOAA Ship Thomas Jefferson completed her sea trials this week in preparation for the 2013 field season.
Each year, prior to departing for working grounds, the Thomas Jefferson transits to the Chesapeake Bay to perform tests on the ship’s and launches’ systems and hydrographic survey equipment. Crews conduct numerous tests to check the accuracy and precision of multibeam echosounders, side scan sonar, and the sophisticated suite of programs that process all the data. Additionally, this is an opportunity to ensure the safety of the vessel and her crew by performing numerous safety drills and readdressing safety standards and operating procedures.

A nation pays final tribute to Civil War sailors interred at Arlington National Cemetery

Last week we blogged about the Civil War sailors whose remains were being interred at Arlington National Cemetery on March 8. The funeral, for unknown sailors who were lost when the USS Monitor capsized, was solemn and stirring, and reflected the nation’s great esteem for our fallen patriots. The unknown sailors were lost along with 14 of their shipmates when Monitor sank off Cape Hatteras, N.C., on Dec. 31, 1862.
All 16 sailors will be memorialized on a group marker in section 46 of the cemetery, which is between the amphitheater and the USS Maine Mast memorial.
Rear Admiral Gerd Glang, Coast Survey’s director, was honored to represent NOAA in the officer escort for the caissons. Glang and Rear Admiral Anthony Kurta (USN) served as Escort Commanders, and were joined by Capt. Gary Clore (Navy Chaplain) and Cmdr. Nathaniel Standquist (U.S. Navy Ceremonial Guard), as the nation paid a final tribute.

NOAA Coast Survey director to escort caissons for USS Monitor sailors’ interment at Arlington

On Friday, March 8, a NOAA Corps admiral will have the honor of doing something extraordinary. Coast Survey’s director, Rear Admiral Gerd Glang, will be the NOAA Escort Flag Officer for the full honors funeral of two unknown sailors who went down with the Civil War ironclad USS Monitor in 1862. Rear Adm. Glang will join Rear Adm. Anthony Kurta, U.S. Navy, as the two officers escort the caissons during the somber event at Arlington National Cemetery.
The interment will be open to the public.

The Monitor sank southeast of Cape Hatteras, North Carolina, during a New Year’s Eve storm, carrying 16 crew members to their deaths.
The wreck was discovered in 1973, and confirmed in 1974 by John Newton and a team from Duke University. The ironclad was lying upside down with the turret separated from the hull, resting in 230 feet of water approximately 16 miles off Cape Hatteras. In the late 1990s through 2002, experts recovered iconic Monitor artifacts, which are now conserved at the Mariners’ Museum in Newport News, Virginia. Two skeletons were discovered in 2002 when the turret was raised from the seafloor, and efforts to identify the remains have been unsuccessful so far.

Coast Survey issues new Arctic Nautical Charting Plan

In June 2011, Coast Survey issued the first edition of the Arctic Nautical Charting Plan, a major effort to improve Arctic chart coverage that is inadequate for modern needs. After consultations with maritime interests and the public, as well as with other federal, state, and local agencies, we have issued the updated Arctic Nautical Charting Plan: A plan to support sustainable marine transportation in the Alaska and the Arctic.
“Maritime challenges are increasing in the Arctic. As multi-year sea ice continues to disappear at a rapid rate, vessel traffic in the Arctic is on the rise,” said Rear Admiral Gerd Glang, Coast Survey’s director. “This is leading to new maritime concerns, especially in areas increasingly transited by the offshore oil and gas industry and cruise liners.”

Hydro survey plans coming together for 2013

Survey ships and contractors are preparing for NOAA’s 2013 hydrographic survey season. Operations are tentatively scheduled for maritime priority areas from Maine’s Penobscot Bay, down the coast to New York and Rhode Island, and further south to coastal Virginia and approaches to Chesapeake Bay. In the Gulf, current plans are for surveying approaches to Mississippi Sound, Barataria Bay, and the Louisiana coast. Pacific Northwest surveys include Strait of Juan De Fuca and offshore Oregon and Washington. Alaskan survey plans include numerous locations, from the extreme southeastern canals, through the islands, and up to Port Clarence, Red Dog Mine, and Point Barrow.
Additionally, Coast Survey’s navigation response teams are lined up to survey in Panama City, Jacksonville, and St. Augustine, Florida; Galveston and Sabine Pass, Texas; Eastern Long Island Sound; and San Francisco Bay.

Recreational boaters get – and give – free nautical information

Getting free information

One of NOAA’s handiest navigation products, especially for recreational boaters, has been Coast Survey’s experimental BookletCharts™ — nautical charts that are easy to download and print from home computers. We have now moved the BookletCharts from experimental stage into official production.
Nearly a thousand newly updated BookletCharts are available free on the Web. The BookletCharts, which cover the 95,000 miles of U.S. coastline and the Great Lakes, are smaller scale than our traditional paper charts, but they contain most of the information found on a full-scale nautical chart. They are in an 8 1/2 x 11 inch PDF format for home printing.
“It is especially appropriate that we unveil these easy-to-use nautical charts as recreational boaters begin to think about their boating adventures for 2013,” explained Capt. Jon Swallow, chief of NOAA Coast Survey’s Navigation Services Branch. “NOAA’s nautical charts help to protect lives and property, and boaters should take advantage of these free nautical products.”
