NOAA announces launch of crowdsourced bathymetry database

By Lt. Cmdr. Adam Reed, Integrated Oceans and Coastal Mapping (IOCM) Assistant Coordinator

Today NOAA announces the end of a testing phase in the development of a new crowdsourced bathymetry database. Bathymetric observations and measurements from participants in citizen science and crowdsourced programs are now archived and made available to the public through the International Hydrographic Organization (IHO) Data Centre for Digital Bathymetry (DCDB) Data Viewer. The operationalized database allows free access to millions of ocean depth data points, and serves as a powerful source of information to improve navigational products.

The crowdsourced bathymetry database, displayed in the IHO Data Centre for Digital Bathymetry Data Viewer, has an updated user interface.

NOAA began database development in 2014 with the IHO Crowdsourced Bathymetry Working Group. The database is part of the IHO DCDB and is hosted at NOAA’s National Centers for Environmental Information (NCEI), which offers access to archives of oceanic, atmospheric, geophysical, and coastal data. Sea-ID, a maritime technology company, provided early testing and support and is currently working to encourage data contributions from the international yachting community. Ongoing participation from Rose Point Navigation Systems, a provider of marine navigation software, helped kickstart the stream of data from a crowd of mariners.

The crowdsourced bathymetry database now contains more than 117 million points of depth data, which have been used by hydrographers and cartographers to improve chart products and our knowledge of the seafloor. NOAA, working with George Mason University, is using the database depths to assess nautical chart adequacy, determine when areas require updated survey information, and identify chart discrepancies before an incident occurs. The Canadian Hydrographic Service used this dataset to update several charts of the Inside Passage, a network of coastal routes stretching from Seattle, Washington, to Juneau, Alaska.

Data are contributed to the database through a variety of trusted sources (e.g., partner companies, non-profit groups)—referred to as “trusted nodes”—that enable mariners to volunteer seafloor depths measured by their vessels. Contributors have the option to submit their data anonymously or provide additional information (vessel or instrument configuration) that can enrich the dataset. The trusted node compiles the observations and submits them to the crowdsourced bathymetry database, where anyone can access the near real-time data for commercial, scientific, or personal use.

Mariners provided millions of bathymetry data points to the crowdsourced bathymetry database by voluntarily submitting the depth data collected by their vessels.
Mariners provided millions of bathymetry data points to the crowdsourced bathymetry database by voluntarily submitting the depth data collected by their vessels.

NOAA invites maritime companies to support this crowdsourcing effort in their systems by making it simple for users to participate. For example, Rose Point Navigation Systems further promoted the IHO crowdsourced bathymetry initiative by moving the option to collect and contribute bathymetry data to a more visible section of their program options menu.

By submitting crowdsourced bathymetry data, mariners provide a powerful source of information to supplement current bathymetric coverage. Nautical charts need to be updated as marine sediments shift due to storm events, tides, and other coastal processes that affect busy maritime zones along the coast. Crowdsourced bathymetry data helps cartographers determine whether a charted area needs to be re-surveyed, or if they can make changes based on the information at hand. In some cases, crowdsourced bathymetry data can fill in gaps where bathymetric data is scarce, such as unexplored areas of the Arctic and open ocean and also shallow, complex coastlines that are difficult for traditional survey vessels to access. Crowdsourced bathymetry data is also used to identify dangers to navigation, in which case NOAA can issue a Notice to Mariners about the navigation hazard within 24 hours.

The utility of crowdsourced bathymetry data extends beyond the territory of the United States and into international mapping efforts. Seabed 2030 is a global mapping initiative to produce a complete, high-resolution bathymetric map of the world’s seafloor by 2030. GEBCO (which operates under the IHO and International Oceanographic Commission) and the Nippon Foundation launched the initiative in 2017, and received NOAA-wide commitment of resources and support.

Seafloor mapping is integral to many NOAA products, and crowdsourced bathymetric data supports NOAA’s Integrated Oceans and Coastal Mapping (IOCM) initiatives to maximize potential sources and use of mapping data. Crowdsourced efforts are poised to become a major source of information for improving nautical chart coverage and accuracy, and the crowdsourced bathymetry database contributes to national and international seafloor mapping efforts as a growing repository of bathymetric data.

Coast Survey prepares to serve nation during 2018 hurricane season

“But, sir, what does the country want in the coast survey? They want a very useful work done, a very important work done, and they want it done in the best manner.” U.S. Senator John Davis (MA), 1849, explaining the importance of the coast survey to safety and the U.S. economy during the 30th Congress, 2nd Session

As the nation’s nautical chartmaker, NOAA Coast Survey provides critical emergency response information to coastal communities and waterways. Each year, Coast Survey prepares for hurricane season in order to perform the work in—as the late Senator Davis put it—“the best manner.” Last year’s string of powerful hurricanes underscored the importance of coordinated efforts for storm preparation, response, and recovery. With the official start of the 2018 hurricane season just around the corner, Coast Survey’s regional navigation managers spent the large part of April and May meeting with U.S. Coast Guard (USCG), port authorities, NOAA National Weather Service, and communities to prepare emergency response capabilities.

Understanding each others’ roles and responsibilities ahead of time is imperative to a response effort as strong storms can shut down ports and compromise our nation’s marine transportation system. Our East Coast and Gulf Coast navigation managers report on NOAA’s survey capabilities and critical assets at hurricane exercises and planning meetings. With Coast Survey’s expertise in underwater detection, NOAA navigation response teams and survey ships are often first on the water following a hurricane, making sure that no hidden debris or shoaling pose dangers to navigation.

This year, NOAA navigation managers participated in hurricane exercises in:

  • Texas: Beaumont, Port Arthur, and Houston/Galveston/Freeport
  • Louisiana: Port Charles, Port Fourchon
  • Alabama: Orange Beach
  • Florida: Lakeland, Tampa, Port Canaveral
  • Georgia: Savannah
  • South Carolina: Charleston
  • Virginia: Hampton Roads
  • Maryland: Baltimore
  • Pennsylvania: Delaware River and Bay (Philadelphia port complex)

Meetings are planned with USCG Sector San Juan staff as well as Puerto Rico South Coast Harbor Safety and Security in early June.

Additionally, Tim Osborn, the navigation manager for the east Gulf Coast, Alan Bunn, the navigation manager for the west Gulf Coast, and Lt. Cmdr. Jay Lomnicky, chief of Coast Survey’s Navigation Response Branch, recently participated in the Gulf Inland Waterways Joint Hurricane Team (JHT) meeting. This large Gulf-wide event held each year at the Port of New Orleans includes USCG, tug and tow industry, pilots, deep draft navigation, ports, U.S. Army Corps of Engineers (USACE), and NOAA partners from Brownsville, Texas, spanning east to Panama City, Florida. Each participant is a working member of the JHT for the current hurricane season.

Capt. Jim Crocker, chief of NOAA’s Navigation Services Division, and Kyle Ward,  navigation manager for the Southeast Coast, participated in a USCG District 7 workshop in Miami, Florida, to discuss the region’s readiness for the upcoming hurricane season. District 7 is responsible for six regionally-based sectors stretching from Charleston, South Carolina, to Key West, Florida, and Saint Petersburg, Florida, to the U.S. Virgin Islands. Last year, each of these sectors was impacted by either Hurricane Irma, Hurricane Maria, or both storms. Hydrographic survey vessels operated by NOAA and the USACE are considered critical assets to the USCG.

When severe weather isn’t heading for the coast, NOAA navigation managers work directly with pilots, mariners, port authorities, and recreational boaters to help identify navigational challenges facing the marine transportation system, and provide the resources and services that promote safe and efficient navigation.

 

 

 

 

 

 

 

NOAA adds grid overlay to chart anchorage areas in Port of New York and New Jersey

NOAA Coast Survey recently released updates for two NOAA electronic navigational charts (NOAA ENC®) in the Port of New York and New Jersey, which added a permanent grid system overlay to anchorages in Bay Ridge, Graves End, and Stapleton. Coast Survey performed the update at the request of the Harbor Operations Steering Committee and collaborated with the Sandy Hook Pilots Association and U.S. Coast Guard (USCG) Sector New York’s Vessel Traffic Services (VTS). 

The overlays, created by the Sandy Hook Pilots, consist of parallel and vertical lines that are labeled and charted over the anchorage areas. The VTS adopted this grid system overlay and uses it to assign specific anchorage locations for ship pilots and captains of tug and barge combinations.

“Incorporating these overlays in an ENC will increase safety and efficiency in the port’s limited anchorage space. VTS will be able to clearly direct a vessel to a specific grid location, and that vessel will be able to see the location on their electronic chart system,” said USCG Capt. M.H. Day, Captain of the Port, Sector New York.

Coast Survey prioritizes new data for chart updates as being either “critical” or “routine” (i.e. “non-critical.”)  Critical corrections – items that pose an immediate danger to mariners – are published by the USCG in their weekly Local Notices to Mariners. Mariners who purchased a paper copy of a NOAA chart may hand correct their chart or purchase an updated chart from one of NOAA’s certified print agents. Digital versions of the charts are updated each week with items published in the USCG Local Notice to Mariners. Mariners interested in seeing where both critical and routine corrections fall on a given chart each week can use the Weekly Updates Site. Updates to this site are underway which will provide mariners greater flexibility in viewing an accumulation of changes over a specified date range rather than viewing them week by week.

NOAA Ship Fairweather begins multi-mission projects in Alaska

In a unique deployment of resources, last week NOAA Ship Fairweather split its scientific team and vessels to tackle two distinct projects in Alaska. Coast Survey physical scientist Katrina Wyllie and Lt.j.g. Bart Buesseler report on the multi-mission projects.

***

On August 9, NOAA Ship Fairweather departed Dutch Harbor, Alaska, for a FISHPAC project, led by Dr. Bob McConnaughey from NOAA’s Alaska Fisheries Science Center. This project’s primary mission is to statistically associate acoustic backscatter returns with the abundances of fish and crabs that frequent the Bering Sea seafloor. The science team accomplishes this with acoustic data from multibeam, single beam, and side scan sonars. Understanding the value of acoustic backscatter as a habitat-defining character will help scientists understand where fish live and the importance of different habitats. The acoustic data will also be used to correct for differences in the performance of research bottom trawls on different seafloor types, so that stock assessments and fishery management can be improved. To make sure the scientists understand what the acoustic data are showing, each day the ship will stop and collect physical bottom samples of the seafloor to see, touch, and interpret their findings. Further increasing the effectiveness of this mission, all of the multibeam bathymetry data acquired will directly support NOAA’s Office of Coast Survey as the data will be used to update soundings on the nautical charts for the eastern Bering Sea where the ship will be operating.

NOAA Ship Fairweather will survey the red tracklines for the FISHPAC project this year. The green lines will be surveyed at a later date.

With Fairweather actively conducting 24-hour ship survey operations in Bristol Bay, there wouldn’t be any chance to deploy her four survey launches for additional acquisition. Sensing an opportunity, the Office of Coast Survey, the command of the Fairweather, and Marine Operations Center-Pacific collaboratively came up with a multi-mission plan to maximize the capabilities of Fairweather during the FISHPAC project. Before departing Dutch Harbor, Fairweather deployed a shore team with the four survey launches to stay in Dutch Harbor and address some critical navigation needs identified by the port.

Although its location is remote, the port of Dutch Harbor is a vibrant and bustling port serving full-size container ships. It is the country’s top fishing port in terms of landings for the past 18 years. Deep draft and ice-free year-round, Dutch Harbor provides a critical link in America’s transportation infrastructure. Trivia buffs may also know that Dutch Harbor is the only other American soil, in addition to Pearl Harbor, to be bombed during World War II. (For more on Alaska in World War II, see USC&GS Ship Hydrographer contributes to significant Allied victory.)

With the increase in commerce flowing into and out of the harbor, local maritime pilots asked Coast Survey navigation manager Lt. Timothy Smith for updated nautical charts to improve the safety of maritime traffic. This need was underscored in July 2015, when a polar ice class vessel ran aground in an area of the chart which hadn’t been surveyed since before World War II. Shortly after this grounding, Fairweather was able to alter their schedule to conduct a response survey in the area of the grounding (green area in project sheet layout, below). Additionally, Fairweather had previously surveyed small high priority areas in 2011 (orange areas).

This month’s collaborative project, performed in conjunction with FISHPAC, provided the perfect opportunity to address these navigational needs. With the survey launches remaining in Dutch Harbor, with a team of scientists, coxswains, and engineers to support them, Fairweather’s shore team will acquire complete coverage multibeam data in the entire project area, totaling approximately 38 square nautical miles, as outlined by the blue shapes in the project sheet layout.

The City of Unalaska has graciously facilitated this unique mission by providing pier space for all four launches for the project’s duration. The team itself has established a base of operations at the Grand Aleutian Hotel, where they have converted a conference room into a command center to process the day’s freshly collected data, while preparing the mission for the subsequent day.

The shore team has plenty of work to keep them busy until August 27, when Fairweather returns to Dutch Harbor after completing the more than 4,000 line-mile  FISHPAC mission and recovers the survey team and launches. Fairweather then transits back to Kodiak, Alaska, for a scheduled inport and well deserved break before hydrographic survey operations resume in the vicinity of Sitkalidak Strait.

Olympic Coast survey provides data for multiple uses

Coastal planners, fishery managers, and oceanographic researchers will soon reap important seafloor and water column data from the coast of Washington, when NOAA Ship Rainier undertakes a special project in the waters within and near the Olympic Coast National Marine Sanctuary in May.

Map of IOCM projects Olympic Coast NMS
The blue lines indicate NOAA Ship Rainier’s survey project areas. From north to south, the project encompasses Juan De Fuca Canyon (65 square nautical miles), Quinault Canyon (378 square nautical miles), and Willapa Canyon (189 square nautical miles). The teal dots in Quinault and Willapa canyons are the locations of deep underwater natural methane gas seeps being investigated in a University of Washington research project. The green shaded area is the extent of the Olympic Coast National Marine Sanctuary.

The project, which is being managed by NOAA’s Integrated Ocean and Coast Mapping program, grew from NOAA’s National Centers for Coastal Ocean Science seafloor mapping prioritization exercise among coastal stakeholders from federal and state (Oregon and Washington) agencies, tribes, and academia. The group determined that one of the biggest needs by most of the organizations was a better understanding of canyon depths, seafloor, and habitat.

A scientific team of experts from the College of Charleston, University of Washington, and Oregon State University will contribute to the NOAA-led multi-disciplinary survey project, gathering data for a host of research projects and ocean management activities. In general, the data will collect swath bathymetry, acoustic backscatter, and water column data to:

  • inform regulatory decisions on coastal development;
  • provide benthic habitat mapping and seafloor characterization for sustainable fisheries initiatives, and to help assess fishery stocks and critical spawning aggregation locations;
  • better understand and manage shelf and canyon resources;
  • aid in resolving multiple-use conflicts;
  • advance research in determining chemical and biological contamination levels; and
  • provide a data repository for the development of ocean tourism and recreational fishing.

Some specific research projects are also planned.

  • A University of Washington scientist will analyze the water column plumes over natural methane gas seeps in the planned survey areas. The university is a leader in the study of methane hydrates.
  • Because Rainier heads to Alaska after the survey in the sanctuary, the ship will also conduct an exploratory survey to obtain seafloor imagery and data over a newly discovered mud volcano in the upper continental slope offshore of Dixon Entrance, just off the Inside Passage near Ketchikan, Alaska. California State researchers will use the data from this 40 square nautical mile survey to analyze the seafloor shape, assess the area for effects on potential tsunamis, and identify unique biological communities.

As part of her regular mission, Rainier will acquire depth measurements and other hydrographic data throughout the entire project to update NOAA nautical charts 18480 and 18500 off the coast of Washington, and chart 17400 in Alaskan waters. The corresponding electronic navigational charts (NOAA ENC®) are US3WA03M, US3AK40M, and US3AK40M.

Chris Stubbs, from the College of Charleston, will serve as the project’s chief scientist. Cmdr. Edward J. Van Den Ameele is Rainier’s commanding officer.

NOAA ship Rainier, a 48-year-old survey vessel, is part of the NOAA fleet of ships operated, managed and maintained by NOAA’s Office of Marine and Aviation Operations, which includes commissioned officers of the NOAA Corps, one of the seven uniformed services of the United States, and civilian wage mariners.

Call for articles! Hydrography: it’s more than charts

In 2005, the International Hydrographic Organization established World Hydrography Day, celebrated annually on June 21. To observe this year’s World Hydrography Day, NOAA’s Office of Coast Survey is calling for articles for an e-publication dedicated to this year’s theme: “Hydrography: It’s More Than Charts.” Hydrography is the science upon which nautical charting is based, but, as this year’s World Hydrography Day theme conveys, researchers and planners use hydrography in a range of activities that benefit the coastal environment and the marine economy.

This e-publication will bring the world of hydrography to non-hydrographers who don’t know what they’re missing! By publishing a variety of short, enlightening articles that describe the many beneficial uses of hydrographic data, we hope to inform – and inspire – policy makers, coastal planners, future hydrographers, and industries that benefit from a vital ocean economy. Let’s share some coastal intelligence.

This call for contributions is open to the public, to researchers, and to people at all levels of local, state, and federal government. International participation is encouraged. We welcome submissions of interesting, original articles discussing the use of hydrographic survey data beyond creating and updating nautical charts. We are particularly interested in case histories of creative approaches and partnerships that solved a problem. Submissions describing visionary concepts for future activities, especially with projects that strengthen smart ocean use and planning, or that contribute to the growth of the ocean economy, are also welcome.

Possible topics may include, but are not limited to, use of hydrography and hydrographic data in:

  • port operations
  • coastal planning and development
  • legal dispute resolution
  • geographical boundary establishment
  • alternative energy siting
  • fisheries management
  • habitat mapping
  • coastal modeling
  • marine resource conservation
  • storm surge forecasting
  • extended continental shelf determination
  • military/naval operations
  • hazard mitigation (e.g., to initiate oil spill trajectory models, or to assist in predicting where spilled oil will go)

NOAA and Coast Guard work together to get more surveying done in the Arctic

By Ashley Chappell, Integrated Ocean and Coastal Mapping coordinator

With 3.4 million square nautical miles of U.S. waters to survey and chart, Coast Survey is up against some big challenges in keeping nautical charts current. A complete survey of those waters would require over 500 ship years and $5 billion ‒ just to acquire the data. It is no wonder that we put substantial effort into a program known as integrated ocean and coastal mapping (IOCM), where trusted partners can provide high quality, standards-compliant hydrographic survey data for a multitude of uses, including chart creation.

One of our biggest challenges is in the Arctic. Whether you knew it or not, the U.S. is an Arctic nation thanks to Alaska, and this formerly frozen region is becoming more accessible to ship traffic as sea ice melts. But much of our Arctic coastal areas have never had full bottom bathymetric surveys, and some haven’t had more than superficial depth measurements since Captain Cook explored the northern regions in the late 1700s.

So NOAA has a dilemma: how do we survey and chart an ice-diminished Arctic when we have limited resources and limited seasonal access? We assessed data age and quality, we reviewed our chart coverage, and we developed the Arctic Nautical Charting Plan for where we would improve chart coverage if we get new data. But our resources for ship and contract surveys can only do so much, and we need more data…

Monitors on SPAR
Hydrographic survey monitors were installed on the U.S. Coast Guard cutter Spar.

Enter our maritime partners, the U.S. Coast Guard. Since 2008, NOAA has been working with the U.S. Coast Guard in Alaska to improve shipping safety. For instance, the Coast Guard buoy tenders, that set buoys and dayboards used to mark the safe passage through waterways throughout Alaska, were finding that some of the natural channels moved from year to year, and so they started using single beam sonar to find the channels. Seeing a way to support this effort, NOAA experts joined U.S. Coast Guard buoy tenders as they headed into the Bering Sea, helping to train Coast Guard personnel to set the buoys safely, quickly, and accurately.

We also started exploring the possibility of the Coast Guard collecting hydrographic data for nautical charts. In 2012, Lt. Cmdr. Mark Blankenship was NOAA’s lead on a joint NOAA/USCG Arctic hydrographic project aboard the Coast Guard Cutter Hickory from Homer, helping to develop an operational procedure to get Coast Guard survey data to NOAA. This year, we are happy to see that professionalism, enthusiasm, and teamwork has resulted in Coast Guard Cutter SPAR providing Bechevin Bay data that will help guide our decision-making for survey priorities.

SPAR commanding officer Lt. Cmdr. Michele Schallip signed the data set on September 10, and highlighted the contributions of Boatswain Mate 1st Class Michael Cobb, who spearheaded the project, with the assistance of NOAA chief survey technician Tami Beduhn, navigation manager Lt. Matt Forney, and Lt. j.g. Jon Andvick.

With the Alaskan coast comprising 57% of the U.S. navigationally significant waters, a multi-agency partnership for hydro survey data is necessary for maritime safety. This year’s successful SPAR survey is an important step in that effort. We look forward to continuing this work with our fantastic Coast Guard partners, and we hope to expand the IOCM concept to other vessels that have survey capability in the Arctic.
