From 2005 through today, NOAA Ship Thomas Jefferson has been surveying Long Island Sound, one project area at a time. Some of the area was last surveyed between the late 1800s and 1939. For the 2014 field season, Thomas Jefferson was assigned her final Long Island Sound project, 89 square nautical miles of Eastern Long Island Sound, Fisher Island Sound, and Western Block Island Sound. When this project is complete, we will have resurveyed over 95% of Long Island Sound and all of Block Island Sound with modern survey technology that allows for a complete picture of the seafloor and highly accurate soundings.
This image depicts Thomas Jefferson‘s bathymetry from eastern Long Island Sound to Gardiner’s Bay.
Data acquired by the Thomas Jefferson will update the region’s nautical charts and will serve other users within NOAA, the U.S. Geological Survey, and a New York and Connecticut Long Island Sound Seafloor mapping initiative. The mapping initiative creates products for habitat mapping and geological interpretation, and supports state planning and management of this vital resource.
Bringing the hydrography of this area into modern times has been a huge task, and we appreciate being welcomed as a part of the area’s maritime community! When Thomas Jefferson was asked to participate in the Connecticut Maritime Heritage Festival in New London this summer, the crew was excited for the opportunity to showcase the results of nearly a decade of surveying effort.
On September 12, Thomas Jefferson docked at City Pier, dressed in semaphore flags to welcome crowds lining the pier eager for guided tours. As the sun set, Thomas Jefferson hosted judges and the announcer during the festival’s lighted boat parade. The ship continued to provide tours the next day, and was the highlight of the event for many visitors. More than 500 visitors toured from fantail to bridge, learning about the ship’s mission and hydrographic survey operations, life at sea, and maritime heritage of NOAA and the Office of Coast Survey.
As the festival ended, Thomas Jefferson’s crew cast off from City Pier to return to their Long Island Sound working grounds and continue survey operations. We are excited to return to the survey area and complete the 2014 Long Island Sound mapping project.

Port officials around the country know they can rely on the expert advice of Coast Survey’s navigation managers, cartographic experts, and hydrographers as the ports plan the essential improvements necessary for a thriving maritime economy. One example of Coast Survey assistance is in Port Fourchon, Louisiana, where port officials have determined that the volume and density of vessels have reached a level that requires one or more offshore anchorage areas. Sending vessels to a designated anchorage reduces the population in port and provides a safe area for vessels to power down their engines (rather than hold in place offshore in dynamic positioning mode), which would improve both safety and efficiency in the area known as the “Gulf’s Energy Connection.”
Using nautical charts of the areas, Coast Survey provided a range of possible sites that helped port officials narrow their anchorage options. After navigation manager Tim Osborn worked with the officials, and with additional requirements in hand, Coast Survey cartographic expert Steve Soherr provided a digital graphic showing likely areas, with information that guards against pipeline and platform interference with safe anchorage.
As additional safeguards, hydrographic surveys will likely be needed to confirm that the seafloor of the recommended areas are free of hazards and do not have uncharted pipelines. Coast Survey will work with the Department of Interior’s Bureau of Ocean Energy Management and Bureau of Safety and Environmental Enforcement as needed.
The port will bring its recommendations to the U.S. Coast Guard, who has the authority to designate the anchorages.
Cartographic adviser Steve Soherr, with Coast Survey’s Navigation Services Division, produced this graphic showing the lease blocks, pipelines, and platforms offshore of Fourchon and Belle Pass. Port officials and others will use the image to examine areas offshore that are both free of pipeline hazards and within the depth range required to accommodate offshore service vessels and the other fleets seen at Fourchon.

This summer, the Bering Sea Alliance hosted a private-public summit in Gambell, Alaska, to discuss Arctic resource development and infrastructure. (See page 10 in this edition of the Nome Nugget for a good summary of the meeting.) Lt. Tim Smith, NOAA Coast Survey’s regional manager for Alaska, updated the participants on the status of Arctic nautical charts and described NOAA’s Arctic Nautical Charting Plan. He also outlined the preliminary 2015 survey plans to acquire hydrographic data around Point Hope, Point Barrow, Port Clarence, and Kotzebue Sound, as NOAA strives to ensure the navigational safety of the increasing ship traffic through Arctic waters.
In addition to his role as navigation manager and NOAA Corps officer, Lt. Smith is one of NOAA’s best photographers. His photos of the area around Gambell are better than words in conveying the beauty of this remote area of Alaska.

NOAA today announced that Lake Assault Boats of Superior, Wisconsin, will build two small vessels for the Office of Coast Survey’s navigation response program, part of a plan to eventually replace all six of the program’s small survey boats. The combined cost of both 28-foot vessels is $538,200.
“All of the navigation response team survey boats are nearing or have exceeded their designed service life,” said Russ Proctor, division chief of Coast Survey’s Navigation Services Division. “A phased program to replace the navigation response team boats over the next three to five years will help NOAA maintain the program’s crucial capacity for inshore surveys and rapid response in emergencies.”
The navigation response team (NRT) boats, which accommodate three-person crews, carry high-tech multibeam echo sounders and side scan sonar to conduct hydrographic surveys in critical navigation areas. The surveys collect data to update nautical charts, and search for underwater debris or shoaling that could pose a danger to navigation — especially after hurricanes or other national emergencies.
“The modernization of the NRT fleet will continue to ensure reliable and rapid deployments to ports that need chart updates and assistance with recovery after severe weather events, even as it helps NOAA hold down costs,” Proctor said.
Coast Survey is phasing the retirement of its current fleet of NRT vessels, prioritizing the replacement of boats experiencing the highest escalating maintenance costs. Coast Survey expects delivery of the first two boats in April 2015.
The six navigation response teams are placed strategically around the country, and each boat can be transported over land. In the past three years, underwater searches by NRTs have helped to speed the resumption of maritime commerce following Hurricane Isaac (in Port Fourchon, Louisiana); Sandy (in the Port of New York / New Jersey, and in Delaware Bay); and the 2011 tsunami (Crescent City and Santa Cruz, California). An NRT also assisted the National Park Service in re-establishing safe navigation and docking at the Statue of Liberty after Sandy, and surveyed the Potomac River security zone in preparation for the 2013 Presidential Inaugural.
Nautical chart data acquired by the navigation response teams supplement hydrographic surveys conducted by NOAA ships Rainier, Fairweather, Thomas Jefferson, Ferdinand R. Hassler, and research vessel Bay Hydro II, as well as private survey companies under contract to NOAA.
Escorted by harbor police after Hurricane Isaac, the Coast Survey navigation response team had to skirt downed utility poles and hanging wires on closed Hwy 1, as they made their way from Lafayette to Port Fourchon.
A navigation response team had to clear away debris on the ramp so they could survey Marcus Hook Anchorage on the Delaware River in Sandy’s aftermath.
Last week we blogged about Coast Survey’s research vessel Bay Hydro II, a small hydro research vessel that delivers big results. The vessel was heading into Baltimore Harbor for five days of public tours at Star Spangled Spectacular.
The Bay Hydro II crew and headquarters personnel had a great time with everyone — from the kids who learned about charts from an admiral, to the map geeks who enjoyed a discussion down in the hydro weeds. More than 4,000 people toured the Bay Hydro II during the celebration, and we hope they all learned at least a little about hydrographic surveying and nautical charts.

Okay everyone, take a break! The Blue Angels are coming…

Remember when your mom told you, “The best things come in small packages”? It turns out that is true for more than diamonds, puppies, and kids who think they are too short.
Today it was my privilege to ride with the 57-foot Bay Hydro II, one of NOAA’s smallest research vessels, as she came into Baltimore Harbor for the Star Spangled Spectacular, a festival that celebrates the 200th anniversary of our National Anthem. As we sailed alongside the impressive NOAA Ship Okeanos Explorer, past historic Fort McHenry, a 19th century cannon boomed ‒ probably sounding much as it did 200 years ago during the War of 1812, when the British attack was turned back at Baltimore. With that historic reminder, I was struck by how the Bay Hydro II represents Coast Survey’s two-century commitment to the Chesapeake Bay, starting with our surveys in 1843.

(Historical note: Even though President Jefferson ordered the Survey of the Coast in 1807, the U.S. Coast Survey was not able to assist during the War of 1812. We were still organizing and, in fact, the first superintendent of Coast Survey was in England when war broke out. Ferdinand Hassler was trying to recruit surveying and cartographic experts and was searching for the proper equipment. He was not able to return to the U.S. until after the war. Some historians think Hassler may have been detained in England at what could euphemistically be called a “special invitation” of the British government.)
Bay Hydro II, the successor to the original productive Bay Hydrographer, was only commissioned five years ago. She was built for the Bay. As U.S. Senator Barbara Mikulski wrote in 2009:
“The Port of Baltimore depends on accurate charts to ensure maritime traffic flows freely, and to help keep the Bay safe from environmental disasters that could result from vessels striking uncharted hazards… Investing in advanced technology, like the Bay Hydrographer II and the sonar equipment it uses, is especially important for keeping America competitive in a global arena. Much of the charting equipment and software currently used within NOAA’s hydrographic fleet was first tested and proven right here in the Bay using this vessel’s predecessor.
“I’m proud to have such an advanced test platform in Maryland’s backyard, keeping America safe, and keeping America innovative.”
The Bay Hydro II is meeting Senator Mikulski’s vision for safety and innovation.
Bay Hydro II surveyed in Hampton Roads following Hurricane Irene, speeding the resumption of port operations
Bay Hydro II has an impressive record. She was the first vessel in Norfolk waters after Hurricane Irene and Sandy, searching for underwater debris to speed resumption of shipping and naval operations in Hampton Roads. In addition to leading Coast Survey evaluations of emerging hydrographic survey technologies, she has assisted U.S. Navy researchers who are testing new technologies. She has rescued stranded boaters and removed debris that posed a danger to navigation in the Bay. And by participating in local community events, the Bay Hydro crews have educated tens of thousands of people about the Bay’s marine characteristics and maritime importance.
Speaking of education… At Baltimore’s 2012 Sailabration, nearly 9,000 people toured this mighty little research vessel for an introduction to NOAA’s hydrographic surveys. With more than a million people expected for this year’s Star Spangled Spectacular, from Sep. 11 to Sep. 15, I’d be surprised if the three-person Bay Hydro crew has any voice left on Tuesday.
This weekend, a lot of people are going to discover how a small research vessel delivers big results.
