Office of Coast Survey 2024 Year in Review

A group of images showing various activities undertaken by the Office of Coast Survey throughout the course of 2024.

As we look ahead to continued progress in 2025, NOAA’s Office of Coast Survey is proud to share some highlights of the past year with you. We mounted successful emergency responses to reopen ports quickly and safely after hurricanes and a bridge collapse; completed a five-year process to transition to fully electronic navigational chart production; provided hands-on learning experiences for students aboard NOAA Ship Nancy Foster; and much more, all in service of delivering authoritative ocean and lakebed mapping information as the nation’s chartmaker.

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.

Model Upgrade: Global Extratropical Surge and Tide Operational Forecast System Upgraded to Version Two

Screen captures of two new implementations of version two; federal levees along the Mississippi and flood plain inclusion for Puerto Rico.

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.

Model Upgrade: Extratropical Surge & Tide Operational Forecast System (ESTOFS) is Now Global

An example of maximum forecast water levels (m MSL) from a forecast cycle of Global ESTOFS.

On November 24, an upgrade to Global ESTOFS was implemented to provide NWS forecasters with high resolution water level forecast guidance including storm tide (storm surge plus tides) for the entire globe. Global ESTOFS forecast guidance will be used by forecasters at WFOs and the Ocean Prediction Center (OPC) to generate their storm surge forecasts during winter storms including Nor’easters along the U.S. East Coast.
