The spirit of collaboration aboard Gulf of Mexico cruise

The spirit of collaboration aboard Gulf of Mexico cruise

This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18 th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24...

NOAA-led research identifies areas of global ocean  most vulnerable to ocean acidification

NOAA-led research identifies areas of global ocean most vulnerable to ocean acidification

New NOAA-led research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. The study identifies the Arctic and Antarctic...

Scientists find Southern Ocean removing CO2 from the atmosphere more efficiently

Scientists find Southern Ocean removing CO2 from the atmosphere more efficiently

Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide (CO2) from the atmosphere, according to two new studies. These studies, out today in the journals Geophysical Research Letters (GRL)and Science, make use of millions...

Monitoring seawater reveals ocean acidification risks to  Alaskan shellfish hatchery

Monitoring seawater reveals ocean acidification risks to Alaskan shellfish hatchery

New collaborative research between NOAA, University of Alaska and an Alaskan shellfish hatchery shows that ocean acidification may make it difficult for Alaskan coastal waters to support shellfish hatcheries by 2040 unless costly mitigation efforts are installed to modify...

Research identifies hot spots for addressing ocean acidification risks to US shellfisheries

Research identifies hot spots for addressing ocean acidification risks to US shellfisheries

We caught up with Dwight Gledhill, deputy director of NOAA’s Ocean Acidification Program, and one of the 17 authors of a perspective published today in Nature Climate Change on vulnerability of U.S. shellfisheries to ocean acidification.

NOAA contributes key carbon dioxide data to global carbon assessment

NOAA contributes key carbon dioxide data to global carbon assessment

A global report released this week on changing carbon dioxide levels in Earth’s atmosphere, oceans, and land environment draws heavily from data and observations by NOAA research scientists and their partners. For the first time, the annual assessment by the Global...

Southern Ocean's role in climate, ocean health is goal of $21 million federal grant

Southern Ocean's role in climate, ocean health is goal of $21 million federal grant

The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance...

Greenhouse gases top 400 ppm for three months in a row at Mauna Loa

Greenhouse gases top 400 ppm for three months in a row at Mauna Loa

For the first time since carbon dioxide in the atmosphere has been measured, the levels of this greenhouse gas at Mauna Loa, Hawaii, have been above 400 parts per million every single day for three straight months.

About Us

The Office of Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
