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.Continue reading “The Interagency Working Group on Ocean and Coastal Mapping announces progress report on mapping U.S. ocean, coastal, and Great Lakes waters”
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.Continue reading “NOAA bathymetric data helps scientists more accurately model tsunami risk within Barry Arm”
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.Continue reading “NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping”

NOAA recently hosted its fourth NOAA Navigation Industry Day at the Annapolis Yacht Club adjacent to this year’s Annapolis Boat Show. This annual event welcomed maritime application and navigation system developers interested in learning about the latest freely-available navigation-related data streams, models, and products that NOAA offers.

NOAA’s Office of Coast Survey quickly updated NOAA electronic navigational charts (NOAA ENC®) to accurately reflect the 225 foot expansion of a slip in Port Everglades, Florida. Now at a total length of 1,125 feet, the elongated slip allows larger ships to dock with confidence. The Port Everglades Pilots – maritime pilots who maneuver ships through crowded harbors and confined waters – requested the chart update. With ENCs that accurately reflect the slip expansion in their hands, pilots can easily communicate to vessel captains that it is safe to dock their vessels in the slip.
Port Everglades is one of the top three cruise ports in the world, and is among the most active cargo ports in the United States. Every slip is kept in high use, and Coast Survey used a new data process that allowed the most critical and valuable information to be applied quickly and made available to the end user.

NOAA’s navigation response team 2 (NRT2), homeported in Fernandina Beach, Florida, conducted a survey around the Sunshine Skyway Bridge, which spans Tampa Bay. The U.S. Coast Guard (USCG) and additional members of the Tampa Bay Harbor Safety Committee requested the work and expressed interest in establishing alternate routes for recreational boating traffic. Alternative routes will alleviate increasing congestion where the main ship channel passes beneath the bridge. This area is naturally restrictive to navigation and, as a result, there have been multiple accidents and near accidents here in the past. Continue reading “NOAA surveys for recreational boat traffic safety in Tampa Bay”
As Gulf ports in the path of Hurricane Isaac bring operations back up to normal, Coast Survey’s navigation response team has finished its hydrographic surveys at Port Fourchon and is heading back to its regularly scheduled 2012 survey of the sea floor in the Port of Houston and Galveston Bay navigational areas.
Port Fourchon started allowing ships to enter the port yesterday, after NRT4 found only minor shoaling and no underwater debris that would pose a danger to navigation.
