🏳️NOAA's National Ocean Service
oceanservice.noaa.gov
In the U.S., where over half of us live along the coast and more than 78 percent of our overseas trade by volume comes and goes along our marine highways, the health of our coasts is intricately connected to the health of our nation's economy. The National Ocean Service (NOS) translates science, tools, and services into action, to address threats to coastal areas such as climate change, population growth, port congestion, and contaminants in the environment, all working towards healthy coasts and healthy economies.

##### [**Experts, technology support DCA aircraft collision recovery efforts**](/news/feb25/dca-crash-response.html)
In the wake of the aircraft collision over the Potomac River near Ronald Reagan Washington National Airport (DCA), NOAA’s National Ocean Service activated response teams to support response and recovery efforts. Tragically, the incident claimed all 67 lives aboard the two aircraft and created significant recovery and salvage obstacles due to the frigid waters and complex wreckage field.

Navigating New York waterways just got a bit easier. The Hudson River Estuary Physical Oceanographic Real-time System (PORTS®) system delivers real-time oceanographic and meteorological observations that can improve maritime safety and inform coastal resource management in the region. Commercial mariners, recreational boaters, resource managers, and coastal planners can use the online tool to access real-time water level data from Sleepy Hollow to Troy, New York.

##### [**Advancements in modeled coastal water level data**](/aa-updates/advancements-mcwl-data.html)
Nicole LeBoeuf, NOS assistant administrator, highlights how the recent release of the Coastal Ocean Reanalysis, or CORA, closes the gap between NOAA tide stations, allowing coastal communities to better understand and make informed decisions about their flood risks.

##### [**Explore the first modeled water level and wave dataset**](/news/jan25/NOS-releases-first-modeled-dataset.html)
Imagine your community is located along a rural part of the South Carolina coast and you’re trying to plan for future coastal flooding. Planning like this often starts with understanding historic changes in water levels and flood risks in your community. To aid in this understanding, NOS launched the Coastal Ocean Reanalysis, the first comprehensive modeled dataset for the Atlantic, Gulf of America, and Caribbean coasts.

##### [**NOAA announces Papahānaumokuākea National Marine Sanctuary**](https://sanctuaries.noaa.gov/news/2025/noaa-announces-papahanaumokuakea-national-marine-sanctuary.html)
NOAA has announced its decision to designate Papahānaumokuākea National Marine Sanctuary, a 582,570 square-mile area in the Pacific Ocean that is two times the size of Texas. The sanctuary is within the existing Papahānaumokuākea Marine National Monument, and provides additional protections and management tools to strengthen conservation of the marine areas of the monument.

Good news for a new year! NOS and partners recovered $40 million from polluters in 2024 that will fund restoration of waterways and their habitats following oil spill and industrial pollution incidents. These restoration efforts will benefit fish, wildlife, and communities disproportionately impacted by pollution.
