Backscatter and oil platforms – a Channel Islands adventure

After enjoying the California sunshine in San Francisco Bay, NOAA Ship Fairweather began its transit down the coast towards Santa Barbara, California. The ship would not anchor for the next sixteen days, leaving all crew on 24-hour rotations. Thankfully, the already attenuated crew was visited by augmenting scientists and hydrographers – Physical Scientist Devereaux from the Pacific Hydrographic Branch, HHST Arboleda from NOAA Ship Thomas Jefferson, and HAST Schrader from NOAA Ship Rainier. Together, they traveled south to complete one of the last projects of the season, the area in and around Channel Islands National Marine Sanctuary.

New NOAA website provides marine navigation resources in a central location

Commercial vessels navigating in the Port of Los Angeles-Long Beach

A recently launched website from NOAA’s Precision Marine Navigation (PMN) program will improve the use and accessibility of NOAA’s marine navigation products and services. The website, Marine Navigation, includes links and short descriptions to NOAA’s various navigation resources, providing a one-stop shop that mariners can visit to get the data they need. Designed for shipping professionals and recreational boaters alike, the PMN program hopes the website will become a valuable tool to support all mariners in their navigation planning and decision making processes.

Collecting aerial images on the Chesapeake’s Western Shore

By Tom Loeper

Early in the morning of June 15, John Doroba and Tom Loeper met with Anne Arundel Park Ranger Adam Smith to collect aerial oblique images of several rivers on the Western Shore of the Chesapeake Bay. These images will be used to update existing content in the United States Coast Pilot 3, Atlantic Coast: Sandy Hook, New Jersey to Cape Henry, Virginia. In addition to acquiring images, experience gained during the field exercise will be used to update aerial photography specifications in the Coast Pilot manual.

Coast Survey to shut down the Raster Navigational Chart Tile Service and other related services

NOAA will shut down its Raster Navigational Chart (RNC) Tile Service and the online RNC Viewer on October 1, 2021. The NOAA Seamless Raster Navigational Chart Services will be shut down on January 1, 2022. This is part of a larger NOAA program to end production and maintenance of all NOAA traditional paper and raster nautical charts that was announced in the Federal Register in November 2019.

NOAA bathymetric data helps scientists more accurately model tsunami risk within Barry Arm

Barry Glacier, Alaska.

In May of 2020, local geologists identified a steep, unstable slope that has the potential to become a tsunami-generating landslide in Barry Arm, a glacial fjord 60 miles east of Anchorage, Alaska. With documented cases of tsunami-generating landslides in Alaska including Lituya Bay in 1958 and Taan Fjord in 2015, this new hazard immediately caught the attention of state and federal partners who quickly joined forces to quantify the risk to those living and boating in Alaska’s Prince William Sound, specifically the communities of Whittier, Valdez, Cordova, Tatitlek, and Chenega.

United States Coast Pilot® covering the Pacific now in two volumes

Coast Pilot 10 cover

What is currently known as United States Coast Pilot® 7 was first published in 1903. The official published name was United States Coast Pilot—Pacific Coast California, Oregon and Washington. Content and information was inclusive of those three states. After Hawaii became a state in 1959, information on the Hawaiian Islands—including the long string of islands and atolls out to Midway Island—was incorporated into the newly titled United States Coast Pilot 7—Pacific Coast California, Oregon, Washington and Hawaii. In 1988, information originally maintained by the National Geospatial-Intelligence Agency under Publication 126 on the remote Pacific Islands (American Samoa, Guam and the Marianas) was added as a new chapter.

Register for NOAA Nav-cast webinar: How to obtain NOAA ENC-based paper nautical charts

Join us for our next NOAA Nav-cast, a quarterly webinar series that highlights the tools and trends of NOAA navigation services.

How to obtain NOAA ENC-based paper nautical charts after NOAA ends production of traditional paper charts

Recently, NOAA announced the start of a five-year process to end traditional paper nautical chart production.  While NOAA is sunsetting its traditional nautical chart products, it is undertaking a major effort to improve the data consistency and provide larger scale coverage within its electronic navigational chart (NOAA ENC®) product suite. Over the next five years, NOAA will work to ease the transition to ENC-based products, such as providing access to paper chart products based on ENC data. The online NOAA Custom Chart prototype application enables users to create their own charts from the latest NOAA ENC data. Users may define the scale and paper size of custom-made nautical charts centered on a position of their choosing. Users may then download, view, and print the output. The application is an easy way to create a paper or digital backup for electronic chart systems.

This webcast will provide an overview of the sunsetting process and a live demonstration of the NOAA Custom Chart prototype, including a discussion of the improvements that are planned for the prototype.

Date and time: Thursday, January 9, 2020, at 2 p.m. (EST)

NOAA seeks public comment on ending production of traditional paper nautical charts

NOAA cartographers review a traditional printed nautical chart.

NOAA is initiating a five-year process to end all traditional paper nautical chart production and is seeking the public’s feedback via a Federal Register Notice published on November 15, 2019. Chart users, companies that provide products and services based on NOAA raster and electronic navigational chart (NOAA ENC®) products, and other stakeholders can help shape the manner and timing in which the product sunsetting process will proceed. Comments may be submitted through NOAA’s online ASSIST feedback tool.
