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.”

U.S. and Canada eliminate overlapping ENC coverage in the Great Lakes
Countries issue advance notice for changes in electronic charts
To comply with internationally agreed practices, Canada and the U.S. have been eliminating overlapping coverage of electronic navigational charts (ENCs). New changes will soon take effect in the Great Lakes. Under the new ENC coverage scheme, each country is changing their areas of coverage so that only one country’s ENC is available for any given area at a particular scale.
These changes come into effect 0000 Coordinated Universal Time (UTC), on 22 February, 2013.

Coast Survey supports inauguration preparations
It was an honor to assist with preparations for the Presidential Inaugural. Our assistance, provided before the event, was a combined effort by one of our navigation response teams, survey technicians, cartographers, and several NOAA officers. Coast Survey’s work was additionally supported by colleagues at NOAA’s Center for Operational Oceanographic Products and Services.

What is the future of e-Navigation? CMTS wants to hear from you
The U.S. Committee on the Marine Transportation System, a federal inter-agency partnership that develops national MTS policy, is asking for your ideas on the future of e-navigation.
They’ve set up a unique online site to facilitate the conversation, and they invite anyone with an interest in the U.S. marine transportation system to join the discussion. (Deadline for comments is February 28.) For background, you might want to read the committee’s e-Navigation Strategic Action Plan.
As defined by the International Maritime Organization (IMO), e-navigation is “the harmonized collection, integration, exchange, presentation, and analysis of maritime information onboard and ashore by electronic means to enhance berth-to-berth navigation and related services for safety and security at sea and protection of the marine environment.”

Surveys for Maine fishing community buttress new energy technology
By David McIntire, survey technician, Coast Survey Navigation Response Team 4
Down East Maine. For many, this conjures up imagery of rugged, fog-enshrouded coastline carved for centuries by relentless waves and violent nor’easters, where quaint fishing villages and misty lighthouses hug the shoreline, inhabited by hardy mariners who for generations have braved fierce storms and unimaginable winters to make a living where land and sea meet in perhaps the most spectacular way. Yet this is only part of the story where a nostalgic past embraces an innovative future. Eastport, Maine is no exception and NOAA’s Office of Coast Survey is proud to partner in that endeavor.
Fishing has been the lifeblood of Eastport’s economy for generations and, despite the influx of tourism in recent decades, many Down East families still derive their income from the sea. This may sound quaint and romantic, until you realize that the Bay of Fundy is not the idyllic, placid water of postcards and paintings. With tides ranging nearly 30 feet every few hours, inlets become rife with ripping currents as the back bays fill and empty through these narrow, rocky channels. It is within this treacherous environment that the local commercial fishermen risk their lives – and, over the past decade, a number of them have paid the ultimate price.

NOAA Coast Survey cartographers update and maintain over a thousand nautical charts
During the first six months of the Coast Survey blog, we have focused largely on the field work – surveying sparsely charted Arctic waters, responding to calls for help following hurricane destruction, finding dangers to navigation, and even identifying historic wrecks. We haven’t covered the day-in, day-out job that is our reason for existence: creating and updating the country’s nautical charts.
Coast Survey has compiled and maintained the nation’s nautical charts for nearly two centuries, after President Thomas Jefferson approved legislation in the Ninth Congress in 1807, and we now maintain a suite of over a thousand charts. We sometimes get the question, “aren’t you done yet?” Haven’t we finished charting all of the U.S. waters?
The simple answer is no: because storms alter seafloors, and water depths constantly change due to shifting shoals, submerged hazards, and coastal development, Coast Survey must continually update the nation’s nautical charts. Charting those changes, and ensuring chart accuracy and precision, is essential to protecting life and property.
The more complicated answer may surprise you. Many of our nation’s marine shipping lanes, harbors, and port areas haven’t been mapped since the 1920s, when measurements weren’t as precise – or even as accurate ‒ as is possible now. Some areas, especially in Alaska, haven’t had bottom measurements since the mid-1770s.
Coast Survey’s Marine Chart Division employs many of the nation’s best cartographers. Since 2009, cartographers have applied approximately 50,000 critical charting corrections to NOAA’s various charting products. In fiscal year 2012 alone, cartographers applied more than 11,000 critical corrections to chart updates.
Over those four years, Coast Survey has also produced over 500 new chart editions (of current charts), and built 200 new NOAA ENC® (NOAA electronic navigational charts). This includes 155 new chart editions and 56 new ENCs in fiscal year 2012.
This year, Coast Survey produced several brand new nautical charts, including a new chart for the Port of San Juan, Puerto Rico, and for the Kotzebue Harbor in Alaska, where increasing ocean commerce required improved navigational products. Coast Survey also released an updated chart of Norfolk Harbor, with a new inset of the Inner Harbor, which has developed as a multi-purpose port area.
In addition to updating old charts, and creating new ones, Coast Survey is making more information accessible from its electronic navigational charts. Effective early 2012, several of NOAA’s ENCs that cover the approaches to the East Coast now alert mariners when they are approaching the right whale seasonal management areas, giving them better information to plan to reduce their speeds or avoid the areas altogether. The seasonal management areas, as encoded into the ENCs, graphically show the areas where vessels greater than 65 feet in length must travel at 10 knots or less to reduce the risk of collisions with right whales. The ENCs will also provide for an alarm on the ship’s electronic chart display and information system as vessels enter the speed zone, further alerting the bridge watchstander of speed restrictions.
We are seeing a gradual shift from paper nautical charts to raster navigational charts and electronic navigational charts. Over the last four years, the public has purchased nearly 428,000 print-on-demand paper charts, and another 392,000 traditional paper charts. Reflecting the booming technology in navigation, the public has downloaded countless millions of the electronic and raster navigational charts that NOAA offers free on the Internet.
Even while cartographers use their expertise to update and innovate, there is still the matter of uncharted U.S. waters – waters that remain to be surveyed. Coast Survey is mandated to provide nautical charts for all U.S. territorial waters and the U.S. Exclusive Economic Zone, a combined area of 3.4 million square nautical miles that extends 200 nautical miles offshore from the nation’s coastline. A complete survey of all of those waters would require 545 ship years and $5 billion just to acquire the data. Lacking those resources, NOAA has instead established priorities for the hydrographic surveys that acquire data necessary for reliable charts. Those priorities are updated annually, and are available on Coast Survey’s website, as NOAA Hydrographic Survey Priorities.
A critical need for new or updated charts is especially emerging in the Arctic, and Coast Survey’s Arctic Nautical Charting Plan addresses the tasks ahead.
Commercial mariners and recreational boaters will always rely on NOAA’s charts to keep them and their passengers and cargo safe from harm. NOAA’s cartographers will always work to earn that trust.
