U.S. and Cuba work on navigation safety improvements   1 comment

First up, improving charts and geodesy for Straits of Florida 

Coast Survey welcomed Cuban colleagues to NOAA offices this week, as representatives of Cuba’s National Office of Hydrography and Geodesy (ONHG) traveled to Maryland for the first time since last December. In March, NOAA and ONHG signed a Memorandum of Understanding in Havana.

“We’ve identified a broad sweep of navigation issues for collaboration, and we’ve started to produce tangible results,” said Dr. Russell Callender, assistant administrator of NOAA’s National Ocean Service, at the start of three days of work sessions. “On behalf of NOAA, I’d like to express my appreciation for the progress made by our two agencies.”

The MOU, which is focused on improving maritime navigation safety and related areas of mutual interest to protect lives and property at sea, is the framework for continuing consultations between NOAA’s National Ocean Service and ONHG.

“The collaboration between our two countries is the way to move forward,” said Dr. Candido Alfredo Regalado Gomez, chief of Cuba’s National Office of Hydrography and Geodesy. “We are here to work.”

Among other hydrographic discussions, representatives from both agencies will review, revise, and hopefully approve a planned new international chart (INT chart 4149), the first cooperative charting product between the United States and Cuba during the modern era. NOAA expects to release the new chart in mid-December, at a meeting in Brazil of hydrographic officials from the Western Hemisphere. The chart covers south Florida, the Bahamas, and north Cuba, a popular area for both recreational boaters and commercial mariners.

The publication of the new international chart, along with alignment of U.S. and Cuba electronic navigational charts, will resolve many navigational issues as vessels move across the shared maritime border.

In addition to charting, the U.S.-Cuba dialogue has expanded to include an emerging geodetic component. NOAA’s National Geodetic Survey will discuss current datums (North American Datum of 1983 and North American Vertical Datum of 1988) and plans to transition to new datums by 2022. Discussions include both geometric (latitude and longitude) and geopotential (vertical coordinate referenced to Earth’s mean sea level) issues.

Representatives from both agencies have expressed additional interest in tide and current monitoring, modeling, and forecasting. The exchange of data and information will improve the accuracy and quality of these products, as closer direct dialogue between Cuban and NOAA hydrographic offices promises to improve navigation safety in the Florida Straits, the Gulf of Mexico and the wider Caribbean.

NOAA hosts international “Chart Adequacy Workshop”   Leave a comment

Cartographers and hydrographers from twelve countries gathered in Maryland last week to participate in a three-day NOAA workshop on evaluating the adequacy nautical charts. During the workshop, they learned techniques to evaluate the suitability of nautical chart products using chart quality information and publicly available information. The participants then generated key layers in adequacy assessments:

  • Using automatic identification systems (AIS) information to classify navigational routes, they generated a vessel traffic layer.
  • Comparing satellite-derived bathymetry or other surveys of opportunity with the existing chart, to identify areas that showed significant bathymetric changes, they generated a bathymetric difference layer.
  • Classifying chart quality information, they generated a hydrographic characteristics layer.

By involving the guest cartographers and hydrographers in hands-on layer development and use, instructors demonstrated that the procedure is a low-cost tool that can help any hydrographic office assess the adequacy of its charts.

Participants came from Barbados, Brazil, Canada, Japan, Malaysia, Pakistan, Peru, Russia, Vietnam, Netherlands, Mexico, and Thailand. Instructor presentations and GIS laboratory exercises were provided by Dr. Shachak Pe’eri and Lt. Anthony Klemm.

Coast Survey is planning another workshop training session in July 2017.

NOAA and Cuban chartmakers working together to improve maritime safety   2 comments

Callender, Gomez, and Glang

Following up on Coast Survey’s visit to Havana last spring, Cuban hydrographic officials traveled to Maryland on December 15-17, to meet with NOAA National Ocean Service leaders for discussions about potential future collaboration. High on the agenda for Coast Survey is improving nautical charts for maritime traffic transiting the increasingly busy Straits of Florida.

The historic meeting began with Dr. Russell Callender, NOS acting assistant administrator, welcoming the Cuban delegation, led by Colonel Candido Regalado Gomez, chief of Cuba’s National Office of Hydrography and Geodesy.

“You will receive briefings today as a backdrop to the hydrographic collaboration we are pursuing to make maritime navigation safer in the transboundary waters our nations share,” Callender told the group. “I hope your meetings this week in Silver Spring will contribute to your understanding of the breadth and work of NOAA firsthand, and strengthen our work together.”

The five Cuban officials and representatives from NOAA’s navigation services and the National Geospatial-Intelligence Agency worked through the day, explaining the ins-and-outs of each other’s responsibilities and processes. The teams were ready, by the end of the jam-packed agenda, to resolve charting challenges that interfere with smooth navigational transitions from Cuban waters to U.S. waters in the busy Straits of Florida.

First, Cuba’s Office of National Hydrography and Geodesy and Coast Survey’s Marine Chart Division confirmed the division of responsibilities and updated each other on the progress for collaborating on international charts (known in mariner’s parlance as “INT Charts”) 4148, 4149, 4017, and 4021. Then, in a technical move sure to please recreational boaters and commercial mariners alike, the two countries conferred on adjusting Cuba and U.S. electronic navigational charts to eliminate overlaps and gaps in coverage.

U.S. and Cuban officials

U.S. and Cuban officials met at NOAA Coast Survey offices in Silver Spring, Maryland, for an intensive day of reports and collaboration. From left to right, Dr. Russell Callender, acting assistant administrator for the National Ocean Service; Rear Admiral Gerd Glang, director of Coast Survey; Richard Edwing, director of CO-OPS; John Lowell, the National Geospatial-Intelligence Agency’s chief hydrographer; Tim Wiley, environmental engagement officer, Office of the Coordinator for Cuban Affairs, U.S. Department of State; Captain Richard Brennan, chief of Coast Survey Development Laboratory; Sladjana Maksimovic, Coast Survey cartographer; Edenia Machin Gonzalez, scientist, Cuba’s National Cartographic Agency; Ramon Padron Diaz, frigate captain and chief of Hydrographic Department, Cuba’s National Office of Hydrography; Colonel Candido Regalado Gomez, chief of Cuba’s National Office of Hydrography and Geodesy; and Victor E. Aluija Urgell, lieutenant/general director, GEOCUBA Marine Studies.

By examining adjacent and adjoining ENCs, both sides were able to confer on ways to improve chart coverage in the busy Straits of Florida, where chart misalignments can play havoc with navigational systems as a vessel moves across maritime borders. Countries around the world regularly resolve these issues, as the U.S. does with Canada and Mexico, through regional consultations hosted by the International Hydrographic Organization but, until now, the U.S. and Cuba were unable to work together on their common set of challenges.

Coast Survey initiated the charting discussions earlier this year, when a team of cartographic professionals traveled to Havana in February for three days of meetings with Cuban officials from the Office of National Hydrography and Geodesy and GEOCUBA. During the visit, the Americans and Cubans agreed to work together on a new international paper chart, INT Chart 4149, which will cover south Florida, the Bahamas, and north Cuba. The Office of Coast Survey is now creating the chart, using data supplied by the United Kingdom Hydrographic Office and the Cubans in addition to U.S. data, and plans to publish the new chart in 2016.

This week’s charting progress follows closely on another major accomplishment. Last month, NOAA Administrator Dr. Kathryn Sullivan and Dr. Holly Bamford, acting assistant secretary of conservation and management, traveled to Havana to sign a Memorandum of Understanding on Marine Protected Area cooperation between our two countries. The agreement provides an opportunity for the U.S and Cuba to develop science, education, and management programs between sister sites in both countries, and will strengthen our collaborative relationship.

“The Cuban maritime industry, like many U.S. ports, is building new infrastructure to support commerce and tourism,” said Rear Admiral Gerd Glang, director of Coast Survey. “Like us, they are improving their charts as port and coastal uses evolve, to support expanding maritime commerce.”

“We are now able to work together, as we do with other nations, to coordinate chart coverage and data acquisition.”

In addition to hours of indoor meetings, the Cuban delegation was able to spend some time discussing data acquisition onboard Coast Survey’s research vessel, Bay Hydro II, homeported in Solomons, Maryland. Kathryn Ries (in blue jacket), deputy director of Coast Survey, hosted Ramon Padron Diaz, frigate captain and chief of the Hydrographic Department, Cuba’s National Office of Hydrography; Victor E. Aluija Urgell, lieutenant/general director, GEOCUBA Marine Studies; Edenia Machin Gonzalez, scientist, National Cartographic Agency – Cuba; Yanet Stable Cardenas, first secretary, Embassy of the Republic of Cuba; and Colonel Candido Regalado Gomez, chief of Cuba’s National Office of Hydrography and Geodesy.

 

Nigerian naval officer augments on NOAA survey ship   Leave a comment

by Ensign Kaitlyn Seberger, Junior Officer, NOAA Ship Thomas Jefferson

Sub-Lt. Uchechukwu Erege deploys a conductivity-temperature-depth cast to obtain sound speed.

This fall, NOAA Ship Thomas Jefferson has had the pleasure of hosting Sub-Lieutenant Uchechukwu Erege. Sub-Lieutenant Erege, known to the ship’s crew as “UK,” is a hydrographer in the Nigerian Navy Hydrographic Office. The Nigerian Navy Hydrographic Office is the national hydrographic authority for the country and is responsible for conducting hydrographic surveys in territorial waters, ensuring nautical charts are up-to-date, processing bathymetric data, and providing Notice to Mariners for hazards to navigation.

UK joined the Nigerian Navy in 2012 after graduating with distinction from the University of Lagos with a bachelor’s and master’s degree in geoinformatics. He then completed a 10-month training program at the Nigerian Defense Academy before transitioning to his current position in the hydrography branch.

“At the time, the Nigerian Navy was searching for graduates in various technical fields,” UK says, “and joining the Navy was a great opportunity to serve my country and secure a job in my field of study.”

The United States and Nigeria are both member States of the International Hydrographic Organization (IHO), whose primary aim is to ensure the world’s oceans and navigable waterways are surveyed and charted. Through a grant funded by IHO and the government of South Korea, members of developing countries are able to attain higher education in the field of hydrography. UK was awarded this grant in 2014 and used it to attend the University of Mississippi’s 12-month master’s program in hydrographic science.

“My wife, Ezinne, has been very supportive during my time in the U.S.,” UK explains. “I would not have had as much success here without her.”

During his time at the University of Mississippi, a professor put him in contact with Captain Shep Smith, commanding officer of NOAA Ship Thomas Jefferson. Through a recommendation from the Nigerian Chief of Naval Staff and Capt. Smith, UK augmented for three months on Thomas Jefferson.

“I thought it would be a good opportunity to see how hydrography is practiced outside of Africa,” UK says. “I wanted to develop new skills that would be an asset to my office. My experience at the University of Mississippi and on NOAA Ship Thomas Jefferson has been a great way to network with other hydrographic entities and build international partnerships.”

While on Thomas Jefferson, UK gained hands-on experience as a sheet project manager, and in ship and hydrographic survey launch acquisition of multibeam and side scan sonar data, conductivity-temperature-depth casts, system integration, and troubleshooting.

“As a project manager, I was responsible for ensuring adequate data collection and maintaining good data management. The skills I gained on TJ will be a valuable asset when I return to Nigeria.”

UK proposes creating standard operating procedures in his office, for processing efficiency. An SOP for public affairs can also help inform the country of hydrographic survey projects. UK would also like to recommend more collaboration with international agencies, such as NOAA, and with Nigeria’s West African neighbors in regards to hydrography.

U.S. Chart No. 1 moves into electronic age   3 comments

For the 65 years since the U.S. Coast and Geodetic Survey issued the first edition of U.S. Chart No.1 in 1948, mariners have had a standard guide for understanding the symbols, abbreviations and terms used on paper nautical charts. In a major step forward, a new edition of that guide also describes the symbols specified by the International Hydrographic Organization for the display of electronic navigational charts (ENC) on Electronic Chart Display and Information Systems (ECDIS).

SymbolGlobeSeveral maritime nations produce their own versions of Chart 1. The U.S. Chart No. 1 describes the symbols used on paper nautical charts produced by NOAA and the National Geospatial-Intelligence Agency (NGA). The new U.S. Chart No. 1 is the first “Chart 1” produced by any country to show paper and electronic chart symbology side by side.

“Navigational charts moved to electronic format more than 15 years ago, and downloads of NOAA ENCs® now far outpace sales of paper charts,” explains Commander Shep Smith, division chief of Coast Survey’s Marine Chart Division. “Most of the symbology used to display ENCs is intuitive to the experienced mariner, but caution tells us that mariners will be safer when U.S. Chart No. 1 explains the symbols that appear on their electronic displays.”

U.S. Chart No. 1: Symbols, Abbreviations and Terms used on Paper and Electronic Navigational Charts, produced jointly by NOAA and NGA, is actually more like a book than a chart. The 129-page Edition 12, now being released, supersedes all previous editions and is available for free from the Coast Survey website. Printed copies may be purchased through one of the certified publishing agents listed on the NOAA U.S. Chart 1 download webpage.

Joint Canada-U.S. mapping cruise in the Atlantic winding up   1 comment

RV Atlantis

UNOLS Research Vessel Atlantis, operated by the Woods Hole Oceanographic Institution, transits to a joint Canada-U.S. survey location in the North Atlantic.

The U.S. and Canada have been surveying in the northern Atlantic Ocean this summer, gathering data to support both countries’ territorial claims under the United Nations Convention on the Law of the Sea (UNCLOS). The survey project started on August 15, and the ship is scheduled to return to Woods Hole, Massachusetts, on September 10.

Lt. Briana Welton, a NOAA Corps officer, is representing the Office of Coast Survey and the NOAA-University of New Hampshire Joint Hydrographic Center, as the team of eight Canadian and U.S. hydrographers and geologists work onboard the University-National Oceanographic Laboratory System’s Research Vessel Atlantis. (The Woods Hole Oceanographic Institution operates the Atlantis).

This image shows the multibeam sonar coverage of 116,600 square kilometers, as of noon 4 September 2012, overlaid on a Canadian nautical chart. (Red dashed line shows where the foot of the slope was originally thought to be located.)

The survey team has been mapping the North Atlantic Continental Slope on the Canadian side of the Hague Line, acquiring multibeam, sub-bottom profiler, magnetic, and gravity data. (Check out Where is Atlantis Now?, for a great map of their cruise.)

The national effort to establish the full extent of the continental shelf is vital to the U.S. economy, as the ocean shelf has energy and mineral resources likely worth many billions of dollars. The process for extending the shelf is outlined by the U.S. Extended Continental Shelf Project:

Under international law, as reflected in the Convention on the Law of the Sea, every coastal State [country] automatically has a continental shelf out to 200 nautical miles (nm) from its coastal baselines, or out to a maritime boundary with another coastal State. However, a coastal State may define a continental shelf beyond 200 nm (called an extended continental shelf), if it meets the criteria outlined in Article 76 of the Convention. The process requires the collection and analysis of data that documents the natural prolongation of the continental landmass beyond 200 nm as determined by the formulae and limit lines in Article 76.

NOAA is one of the U.S. agencies leading the effort to collect the data that would allow our Nation to extend the shelf.
