The Interagency Working Group on Ocean and Coastal Mapping announces progress report on mapping U.S. ocean, coastal, and Great Lakes waters

Graphic showing the percentage of coastal, ocean, and Great Lakes waters of the United States that are unmapped as of January 2022.

The Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) has released the third annual report on the progress made in mapping U.S. ocean, coastal, and Great Lakes waters. Knowledge of the depth, shape, and composition of the seafloor has far-reaching benefits, including safer navigation, hazard mitigation for coastal resilience, preservation of marine habitats and heritage, and a deeper understanding of natural resources for sustainable ocean economies. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone and the global Seabed 2030 initiative make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

Alaska to Greenland via the Northwest Passage

Coast Guard Cutter Healy conducts Arctic patrol in support of the Office of Naval Research
By Lt. Patrick Debroisse

In August and September 2021, the U.S. Coast Guard Cutter Healy transited through the Northwest Passage, from Alaska to Greenland. This voyage provided members of the University of New Hampshire’s Center for Coastal and Ocean Mapping/Joint Hydrographic Center (CCOM/JHC) the opportunity to collect data, helping to fill gaps in current hydrographic coverage in the passage and in the U.S. Exclusive Economic Zone (EEZ). Data in the Arctic where sea ice impedes ships is sparse. This is concerning as the Arctic nations, especially the United States, Canada, and Greenland evaluate both extended continental shelf claims and the potential for shipping routes through the Northwest Passage.

The Interagency Working Group on Ocean and Coastal Mapping announces progress report on mapping U.S. ocean, coastal, and Great Lakes waters

The Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) released the second annual report on the progress made in mapping U.S. ocean, coastal, and Great Lakes waters. The depth, shape, and composition of the seafloor are foundational data elements that we need to understand in order to explore, sustainably develop, conserve, and manage our coastal and offshore ocean resources. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone and the global Seabed 2030 initiative make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping

This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.

NOAA released the first annual report on the progress made in mapping U.S. ocean, coastal, and Great Lakes waters. The depth, shape, and composition of the seafloor are foundational data elements that we need to understand in order to explore, sustainably develop, conserve, and manage our coastal and offshore ocean resources. The 2019 Presidential Memorandum on Ocean Mapping of the United States Exclusive Economic Zone and the Shoreline and Nearshore of Alaska and the global Seabed 2030 initiative make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

NOAA hydrographic community prepares for field season at annual workshop

Attendees of the NOAA 2020 Field Procedures Workshop.

The field of hydrography, like most sciences, is comprised of experts honing their craft, improving their tools, building upon the successes of previous years, and learning from their mistakes. Hydrographers typically accomplish this iterative process in the field, publishing papers, presenting at industry conferences, and often through discussions over the phone or via email. However, once a year, the NOAA hydrographic community — those who measure and describe the features of the seafloor to update nautical charts and support a variety of sciences — meets at the Field Procedures Workshop to not only share information, but have frank discussions about their challenges and the path forward in preparation for the upcoming hydrographic field season.

S-100 sea trials: working toward harmonized navigation products

International team participating in the S-100 sea trial.

By Julia Powell, deputy division chief of the Coast Survey Development Lab

On August 27, an international contingent from the United States (NOAA), the United Kingdom Hydrographic Office, and the Canadian Hydrographic Service participated in the S-100 sea trial in Busan, Republic of Korea.

S-100 is the International Hydrographic Organization’s (IHO) Universal Hydrographic Data Model’s framework standard from which a variety of product specifications can be developed for use within navigation systems and marine spatial data infrastructure.  For many years, NOAA and the Ministry of Fisheries of the Republic of Korea have had a Joint Project Agreement and one of the projects is to develop and promote and S-100 test bed.  This test bed is designed to help further the development of S-100 infrastructure used to develop S-100 related products and further the testing of S-100 interoperability within navigation systems.

NOAA hosts 2019 Nautical Cartography Open House and Chart Adequacy Workshop

Sean Legeer shows a digital cartography display to visiting students.

Last week, NOAA’s Office of Coast Survey held its third annual Nautical Cartography Open House welcoming over 250 attendees from the U.S. and abroad. Government agencies, industry and academic partners, and members of the public attended. The open house featured posters, presentations, tours, and exhibits centered around four themes: Bathymetric Databases, Custom Charting, Innovative Cartography, and Precision Navigation. Dr. Shachak Pe’eri, organizer of the event and chief of the Cartographic Support Branch in the Marine Chart Division, welcomed attendees in the morning and John Nyberg, chief of the Marine Chart Division, gave the keynote speech.

NOAA hosts 2018 Chart Adequacy Workshop

On July 23, NOAA Coast Survey hosted a three-day Chart Adequacy Workshop that included participants from 13 countries. This is the fourth Chart Adequacy Workshop held at NOAA’s Silver Spring, Maryland campus.

The main goal of the workshop is to provide training for professional cartographers and hydrographers on techniques for assessing nautical chart adequacy using publicly-available information, such as satellite images and maritime automatic identification system (AIS) data. The participants received an overview on Coast Survey datasets, processes, and requirements for nautical charts. They also learned about preprocessing hydrographic data, such as loading charts, uploading imagery, and applying electronic navigation charts (ENCs) and AIS point data. Through a series of lab units, the attendees practiced performing the concepts they learned. Continue reading “NOAA hosts 2018 Chart Adequacy Workshop”
