NOAA’s Office of Coast Survey produces and maintains several types of data models and products, from operational forecast systems to nautical charts. One of these models comes from the office’s National Bathymetric Source, or NBS, program which creates and maintains high-resolution bathymetry composed of the best available data. Bathymetry is a term that refers to the depths and shapes of underwater terrain and is a visualization of the “beds” or “floors” of water bodies, including the ocean, rivers, streams, and lakes. This data model is available to the public in a product called BlueTopo.
Data dissemination web interface supports navigation
Imagine navigating a vessel along the coast and planning the approach to your destination, whether that be a local marina or large vessel berth in a harbor. What factors affecting the movement of the vessel should you be aware of once underway and in transit through the entrance and into the port? These may include observations on the present and forecasted weather, water current speed and direction, water depths and tidal direction, and any anomalies or warnings that may exist. Knowing what these factors are will assist you in preparing your vessel for safe passage to the destination.

A look back at 2023 and the Office of Coast Survey’s significant activities throughout the year
NOAA’s Office of Coast Survey is reflecting on a successful and remarkable 2023! We completed many significant activities with meaningful impacts. As we look ahead to more progress in 2024, we are proud to share some highlights of the past year in our Coast Survey Year in Review ArcGIS StoryMap.

By Riley O’Connor
In November 1633, the Ark and the Dove set sail from the Isle of Wight—an island off the south coast of England—carrying English and Irish settlers bound for the new colony of Maryland. By January 1634, both vessels arrived at the Island of Barbados and began heading for the colony of Maryland. These settlers sailed into the Chesapeake Bay, the Potomac River, and eventually, the St. Mary’s River. They stopped roughly 12 miles (19 km) northwest from Point Lookout, where the Potomac River enters the Chesapeake Bay. This group of settlers would go on to found Maryland’s first European settlement and future provincial capital, St. Mary’s City.

By Dr. John Nyberg

NOAA’s Office of Coast Survey Deputy Hydrographer Dr. John Nyberg participated in a State Department Science Fellowship through the U.S. Embassy in Suva, Fiji this past summer. The fellowship’s main goal for the region is to assist in accelerating the use of coastal and marine spatial planning for marine conservation and to deliver a curriculum to support it. Dr. Nyberg was asked to pay particular attention to engaging Kiribati (pronounced Kiribas), home to the Phoenix Islands Protected Area, one of the world’s largest and most important protected areas. The government of Kiribati is in the process of re-evaluating their approach toward managing the area, and one of the primary goals is to encourage the use of marine spatial planning in that process.
NOAA-NSF collaboration – evaluating coastal models utilizing Texas Advanced Computing Center services
The Unified Forecast System (UFS) is a proposed community-based earth modeling system that is designed to incorporate oceanographic forecast model core(s) into a simplified NOAA modeling suite. This simplification is intended to reduce the footprint of the number of NOAA models and thus reduce development, operations, and maintenance.

On March 26, NOAA Ship Rainier set sail from Honolulu, Hawaii on a 3,307-nautical mile expedition to the Western Pacific. Originally planned for 2020, this will be the ship’s first multidisciplinary expedition to Guam and the Commonwealth of the Northern Mariana Islands. This collaborative mission between NOAA’s National Ocean Service and National Marine Fisheries Service will deliver high‐quality data, data products, and tools to the region including a seamless map linking hilltops to underwater depths and integrated data on the surrounding coral reef ecosystems. These data can provide information for countless users to make critical management decisions within disciplines such as habitat management and restoration, tsunami modeling, monitoring, and marine resource management.

Model Upgrade: Global Extratropical Surge and Tide Operational Forecast System Upgraded to Version Two
In late July 2021, the Global Extratropical Surge and Tide Operational Forecast System (Global ESTOFS) upgrade to version two was implemented into operations on the National Weather Service’s (NWS) Weather and Climate Operational Supercomputing System (WCOSS). The modeling system provides forecast guidance for combined water levels caused by storm surge and tides globally, and is to our knowledge the highest resolution global operational storm surge modeling system available today. The forecast guidance from the model is used by forecasters at NWS Weather Forecast Offices (WFO) and the Ocean Prediction Center to generate their storm surge and flood forecasts during storms, including Nor’easters along the U.S. East Coast.

NOAA’s Precision Marine Navigation (PMN) program released two new visualization resources. The first is a beta version Precision Marine Navigation Data Gateway map viewer allowing users to explore NOAA’s S-100 data services. Currently, the Data Gateway presents prototype surface current forecast guidance, but new layers will be added as they are developed. NOAA welcomes feedback on the beta version of the Data Gateway. Please submit all comments to marinenav.team@noaa.gov by March 1, 2021.

Where the river meets the sea can be both a turbulent and vulnerable space, particularly during strong storms when heavy precipitation and storm surge intersect. This intersection is known as “compound inland-coastal flooding,” and until now, had not been carefully studied and implemented in forecasting centers for public guidance due to its inherent complexity. NOAA’s Office of Coast Survey and the Virginia Institute of Marine Science recently developed the Inland-Coastal Flooding Operational Guidance System (ICOGS), the world’s first three-dimensional integrated compound inland-coastal flooding guidance system.
