Rear Admiral Acosta and Master Chief Mazzulo spent time with the future leaders of our Naval service at the historic Tulane NROTC.

Founded in 1938, this unit has a long legacy of producing exceptional officers. As we celebrate our nation’s 250th anniversary, it was a privilege to talk with these midshipmen and newly commissioned Ensigns about the crucial role of Naval Meteorology and Oceanography in achieving decision superiority, as well as the leadership principles, operational experiences, and hard-earned lessons that shape effective warfighters and officers.

The future of our Navy and Marine Corps is in incredibly capable hands!

Fair winds and following seas to these future warfighters!!

As we celebrate our nation's 250th anniversary, we ask that everyone take a moment this Memorial Day to reflect on the freedoms that those who have made the ultimate sacrifice fought to protect.

To our fallen brothers and sisters in the Navy, Army, Air Force, Marines, and Coast Guard: we honor your memory, and we will carry your legacy forward.

Rest Well. We have the Watch.

The Office of the Chief of Naval Operations released CNOte #8, titled the “Continuous Improvement as Warfighting Advantage,” reinforcing that the Navy’s enduring edge is its ability to learn, adapt, and improve faster than any adversary.

Building on “The Way We Fight” (CNOte #4), the message outlines the Navy’s push to institutionalize continuous learning across the Fleet through the Tiered Learning System (TLS) — transforming lessons from operations, exercises, maintenance, and near misses into rapid, Fleet-wide improvements that strengthen readiness, resilience, and lethality.

In a profound demonstration of international unity, the United States Navy is honored to host a special reception aboard the oceanographic survey ship USNS Marie Tharp (T-AGS 66). This reception serves as a dedicated celebration of our enduring allies and partners.

As the United States commemorates the 250th birthday of the Nation and the Navy, this gathering also highlights 200 years of U.S. hydrography—a legacy of oceanographic excellence that continues to secure the world's waterways.

The vessel itself is named after Marie Tharp, the pioneering cartographer who created the first scientific maps of the ocean floor, making it an incredibly fitting venue for an event rooted in maritime science and cooperation.

A free, open, and secure ocean requires unprecedented collaboration. The U.S. Navy recognizes the supreme importance of our allies and partners in achieving this common goal. Whether mapping the seafloor, ensuring the safe transit of global commerce, or strengthening regional security, it is the strength of these combined international partnerships that charts the course for success.

"Hosting our partners aboard the USNS Marie Tharp is a fitting tribute to the power of collaboration," said Rear Admiral Erin Acosta, Hydrographer of the U.S. Navy. "As we celebrate our Nation and Navy's 250th birthday alongside 200 years of American hydrography, we are reminded that no single nation can map or secure the vast oceans alone. Our maritime security, scientific progress, and shared prosperity rely entirely on standing shoulder-to-shoulder with our allies to achieve our common goals."

The reception aboard the USNS Marie Tharp is a testament to the shared vision and mutual respect between the United States and its partners, forging a stronger, more connected maritime future for all.
