NOAA mobile integrated survey team prepares for hurricane season

NOAA’s Office of Coast Survey is the federal leader in emergency hydrographic response. Consecutive strong storms during the 2017 hurricane season made response efforts challenging, and emphasized the importance of having a well-trained and versatile staff. Coast Survey’s regional navigation managers, navigation response teams (NRTs), and mobile integrated survey team (MIST) worked with partners before and after the storms to quickly and safely reopen ports and waterways.

The MIST equipment is a mobile, quick-install side scan and single beam sonar kit that can be quickly set up on a vessel of opportunity. Recently, Coast Survey sent the MIST team to Astoria, Oregon to conduct a hydrographic survey of the Mott Basin area, which the U.S. Coast Guard (USCG) requested to confirm charted depth and obstruction data.

The MIST group used this as an opportunity to give NRTs experience with setup, usage, and tear down of MIST equipment, as well as to perform a system test prior to the upcoming hurricane season.

The team installed and integrated the MIST equipment on a USCG Trailerable Aids to Navigation Boat (TANB) vessel. TANB vessels are normally used for navigation aid maintenance, but can serve as a vessel of opportunity for hydrographic surveys using MIST equipment. During the 2017 hurricane season, NOAA used USCG vessels of opportunity in Florida and Puerto Rico for rapid hydrographic survey response.

Coast Survey’s NRTs conduct hydrographic surveys to update NOAA’s suite of nautical charts. The teams are strategically located around the country and remain on call to respond to emergencies speeding the resumption of shipping after storms, and protecting life and property from underwater dangers to navigation.

NOAA RNC Tile Service displays first ENC-only product

NOAA Office of Coast Survey released its 1:12,000 electronic navigational chart (NOAA ENC®of the Merrimack River, Massachusetts, in the RNC Tile Service. This is the first time a navigational chart—created solely as ENC product—is included in the tile service. The tile service renders a traditional depiction of the nautical chart for use with GPS-enabled electronic chart systems or other “chart plotter” display systems to provide real-time vessel positioning for recreational mariners. This chart is included in the single chart tile sets and the quilted tile sets both in the online and offline versions.

The Merrimack River, located in Massachusetts, is just south of the New Hampshire border.The single chart tile set is named​ 13274K0000_1.

The tile service version of the Merrimack chart retains the look of a NOAA paper chart but is derived from the ENC charting database. This gives users the opportunity to use ENC-only data with a traditional NOAA chart feel. NOAA intends to incorporate all future charts that are produced only as ENCs into the tile service (ENC-only charts are outlined in the National Charting Plan, page 25).

“This release represents a major milestone in nautical charting,”  said Rear Admiral Shepard Smith, the director of Coast Survey.  “This is the first chart that was digital from its inception, breaking with the longstanding practice of digital charts based on paper charts.”  

For professional mariners, it is important to note that there is no paper chart equivalent, and that this chart will not be served by the Notice to Mariners systems provided by the U.S. Coast Guard and National Geospatial-Intelligence Agency.  Updates will be made as necessary by NOAA weekly.  Customers with compatible applications will get the updates automatically.

The original 1:12,000 ENC of the Merrimack River was released at this time last year. Recognizing the need for a more detailed chart, a group of local and state stakeholders concerned with the economic revitalization of the area contacted NOAA to create a new, larger-scale chart. The new, larger-scale ENC was compiled using U.S. Army Corps of Engineers data, NOAA lidar data, and privately funded survey data. When shown in detail, the combined data provides mariners with a clearer picture of the overall conditions and dangers to navigation. The availability of this chart in the RNC tile service provides mariners greater flexibility in viewing the chart.

This update to the RNC tile service also includes the ArcGIS Tile Metadata Service, adding support for source chart metadata from within ArcMap and other GIS applications. Instructions for loading the tile metadata into ArcMap have been added to the developer’s website.

Assisting tow industry along Chandeleur Sound Alternate Route

The Inner Harbor Navigation Channel in New Orleans facilitates the transportation of tens of millions of tons of cargo each year. Since the channel was recently closed for repairs, a temporary Chandeleur Sound Alternate Route was established to ensure the flow of commerce between the western and eastern reaches of the Gulf Intracoastal Waterway. NOAA experts assisted with the alternate route development in various ways, collaborating with the U.S. Coast Guard, U.S. Army Corps of Engineers, and the maritime industry.

Navigation manager Tim Osborn represented NOAA on the Coast Guard’s weekly conference calls on the alternate route, asking for industry suggestions on how we could assist. Based on these collaborations, Coast Survey updated the nautical charts with the newly installed Aids to Navigation, while the National Weather Service began providing localized weather forecasts and warnings along the route. In addition, Coast Survey contracted David Evans and Associates (DEA) to survey the southern 33 miles of the total 66-mile proposed route. The survey required object detection survey coverage, with DEA submitting all observed soundings or obstructions shoaler than 12 feet as dangers to navigation. DEA found three dangers to navigation, and they were subsequently announced in the Local Notice to Mariners and applied to the applicable nautical charts.

NOAA will continue to support the tow industry using the alternate route by adding new navigation data to the chart as we receive it, as well as by providing specialized weather reports along the route throughout the estimated three-month closure of the Inner Harbor Navigation lock in New Orleans.

NOAA Coast Survey, Coast Guard, and Army Corps of Engineers schedule public “listening sessions”

Over the past few decades, mariners have witnessed the rapid development, reliability, and availability of e-navigation components, such as the global positioning system (GPS) and electronic chart display and information systems (ECDIS). These systems, and other technology, have fundamentally changed mariners’ reliance on traditional navigation services. In addition, the ability to manage data and information provided to the mariner through the automatic identification system (AIS) and cellular service has enhanced the interconnectivity between shore side information providers and shipboard users. These technological advances and data flow will help the mariner receive data, transmit data, and generally improve bridge resource management, situational awareness, and navigational safety.

These fundamental changes present the U.S. Coast Guard, U.S. Army Corps of Engineers, and NOAA’s Office of Coast Survey with an opportunity to take the next steps in modernizing federal navigation services. Technology development compels these federal agencies to optimize the current aids to navigation, other maritime information systems, and nautical charting.

We want to hear from you, as we develop a federal development portfolio that will provide coordinated and timely delivery of navigational information and services. We invite you to attend one of our listening sessions, to tell us your emerging requirements for navigational information and service delivery systems in an eNAV environment.

NOAA navigation response teams improve charts for ships transiting Miami and San Francisco

Coast Survey’s navigation response teams, which are 3-person hydrographic survey teams on small boats, have made a fast start on this year’s survey season.

In Florida, where Coast Survey is preparing to issue a “new and improved” Miami Harbor Chart 11468 to alleviate vessel congestion at the Port of Miami, a navigation response team finished final hydrographic surveys to ensure the new chart has the latest and most accurate depth measurements around several areas identified as critical within the port. In just ten days, team members Erik Anderson, James Kirkpatrick, and Kurt Brown acquired, processed, and submitted the multibeam survey data covering 64 nautical miles.

The Biscayne Bay Pilots and others requested the new chart, which is reconstructing old charts in order to provide large-scale coverage of the entire precautionary area where vessels congregate to await pilotage and commit to an approach course to the channel. Updating the chart information and expanding chart coverage will alleviate a navigation safety risk for the world’s busiest cruise port, and will protect endangered coral reefs from inadvertent anchorages.

One interesting side note on the Miami survey… The team found a sunken car, which a Miami Police Department Marine Patrol/Underwater Recovery Detail dive team subsequently investigated. It appears to have been there for approximately 20 years, divers said. We understand they retrieve around 50 cars a year, but have never seen one this old. They plan to raise it later this month. Any bets on make and model?

Meanwhile, in San Francisco Bay, another navigation response team is planning a special hydrographic survey to update NOAA charts 18656 and 18657. The action comes as a follow up to a July 2013 grounding by a tug and a barge carrying 80k barrels of crude oil in Benicia Anchorage 22, near Carquinez Strait, San Francisco. After the accident, team members Laura Pagano, Ian Colvert, and Edmund Wernicke conducted a reconnaissance hydrographic survey to determine if an uncharted obstruction caused the grounding. The survey determined that shoaling was the culprit and the evidence indicated that a charted shoal has been creeping through the Benicia Anchorages towards the federal shipping channel at Carquinez Strait. Last month, the U.S. Coast Guard requested an extensive survey to determine the extent and significance of shoaling in the Benicia Anchorages, and the team is planning to conduct the survey shortly.

NOAA navigation manager Gerry Wheaton suspects heavy sediment runoff from rains over the years have altered the sea floor in navigable areas near the Strait. While the initial NOAA recon survey provided information to notify mariners of the dangers, conducting a full bottom survey to update NOAA nautical charts will provide additional detailed depth information necessary to safely navigate the area.

Great Lakes mariners get new NOAA nautical chart for St. Mary’s River

Vessel operators transiting St. Mary’s River, between Lake Superior and the lower Great Lakes, have a new nautical chart to help lessen the dangers inherent in this narrow and complicated waterway. The first edition of Chart 14887 (St. Marys River – Vicinity of Neebish Island) is available this week as a paper print-on-demand chart, PDF, and raster navigational chart. The electronic navigational chart will be available by March, in time for the beginning of the shipping season. (UPDATE, 2/12/14: NOAA ENC US5MI50 is now available.)

Coast Survey has built the chart from original sources, providing the highest standard of accuracy for hydrographical and topographical features and aids to navigation. The chart provides large-scale (1:15,000) coverage of the up bound and down bound channels of the St. Mary’s River – one of the busiest waterways in the nation. Over 4,100 transits of commercial and government vessels move about 75 million tons of cargo through the 300-day shipping season.

Corrected shoreline, chart 14883
The red lines show the shoreline as depicted before the updates. NOAA cartographers are applying the corrected shoreline and feature positions to the new chart and new editions of current charts in the Great Lakes.

Chart 14887 uses updated shoreline data, collected with NOAA’s high tech remote sensing planes. (See National Geodetic Survey’s shoreline data viewer.) At the 1:15,000 scale, the positions of many of the features were corrected an average of ten meters from positions in prior charts, a vital correction for precision navigation by vessels that can exceed a thousand feet long.

Coast Survey also plans to issue new editions of the current four largest scale charts of the St. Mary’s River in late January. Charts 14882, 14883, 14884 and 14962 will have all new shoreline, updating the locations of features and aids to navigation. These updates for the St. Mary’s River follow 21 new editions for Great Lakes charts from Buffalo to Thunder Bay Island, around the Lower Peninsula to Milwaukee Harbor and Ludington. More updates are slated for 2014 and 2015.

Chart 14887 was compiled by Nathan Burns and reviewed by Laurie Bennett, under the direction of Marine Chart Division branch chief Andy Kampia.

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

USCG-NOAA Cooperative Maritime Strategy

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.

The Father of the Revenue Marine, Secretary Alexander Hamilton once said, “There is a certain enthusiasm in liberty, that makes human nature rise above itself, in acts of bravery and heroism.” Not only is our shared legacy marked in a vision for maritime excellence, but also in front-line acts of courage and inspiration. From rescuing survivors in unforgiving regions like the Arctic since the mid-1800s, to flying through hurricanes today to collect data, our men and women have served America with distinction for over two centuries.

This strategy builds on our legacy and establishes an integrated and coherent course for the future. Moving forward, we will continue partnering to promote a safe and sustainable marine environment, enhance collaboration in the Arctic and Gulf Coast regions, and foster innovation in science and technology. Perhaps most strategic, our Services will build on existing programs to inspire our Nation’s youth academically in the areas of science, technology, mathematics, and marine environmental protection. We will implement this strategy pragmatically and mindful of the fiscal challenges we currently face. It provides a solid vision and is the North Star for our future.
