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.

The members of the federal Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) are thrilled to announce the release of the first Standard Ocean Mapping Protocol (SOMP)! The SOMP is a standardized technical protocol for acquisition, processing, and archiving of ocean and coastal mapping data. It was developed in support of National Strategy for Ocean Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (NOMEC) goals and is built from existing standards and best practices developed by the ocean and coastal mapping community.

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.

This group of settlers would go on to found Maryland’s first European settlement and future provincial capital, St. Mary’s City.

In early May, NOAA’s Office of Coast Survey Deputy Hydrographer John Nyberg, Ph.D., was elected as a director of the International Hydrographic Organization (IHO) during its Third Assembly. The six-year term begins in September and promises to be a critical time for the evolution of digital navigation infrastructure and capacity worldwide, with the implementation of the S-100 hydrographic model. John was nominated by the secretaries of commerce, defense, and state. His role will be to serve as part of the directing committee which is composed of a Secretary General and two directors to manage the day-to-day operations of the organization in order to advance the goals of the Member States.
