Ensuring continuity: A new method for Florida Current transport observations

The flow of the Florida Current, one of the most powerful ocean currents in the world, has been measured by a submarine telecommunications cable between Florida and the Bahamas since 1982. Unfortunately, this record was interrupted in November 2023 due to a mechanical failure of the cable. Building on prior research, a new study presents an alternative method to continue providing the Florida Current daily transport estimates until the cable can be repaired.

Record warm ocean temperatures fuel longest-lasting 2023 US heatwave

Extreme heat is the leading weather-related cause of death in the United States. In a new study published in Nature Communications, scientists found a link between the long-lasting 2023 heatwave over the southwest US and Mexico and the record warm sea surface temperatures in both the Atlantic and Pacific Ocean.

New study reveals record heat and rapid cooling in equatorial Atlantic in 2024

Originally published as an official press release on the University of Miami’s Rosenstiel School’s newsroom website. Atlantic Niño/Niña events can influence hurricane development, but they can be difficult to predict. A new study sheds light on the oceanic chain reaction that can trigger these events, potentially improving our ability to forecast them. A new study […]

Ocean Month: Exploring and understanding our ocean through research cruises

Research cruises are essential for scientists to collect data, deploy instrumentation, and maintain ocean observing systems. NOAA regularly conducts research at sea to study the ocean and atmosphere, advancing our understanding of the ocean, monitoring ocean conditions, and ensuring sustainable fisheries and healthy marine habitats. These expeditions provide essential data for weather prediction, ocean acidification […]

Monitoring vital signs: Tools and technologies at the heart of physical oceanography

In 2018, an Australian couple curiously stumbled upon a bottle of gin washed ashore in Wedge Island, Australia. Yet, there was no gin inside. Rather, preserved within the bottle was a note with the date June 12th, 1886; the name of a German barque, Paula; the ship’s departure and arrival ports; and the exact coordinates […]

Australia to Thailand: I09N GO-SHIP cruise completes voyage 

After nearly 40 days at sea, the I09N GO-SHIP cruise (short for “Global Ocean Ship-based Hydrographic Investigations Program”) aboard the R/V Thomas G. Thompson arrived in Phuket, Thailand on April 27th, successfully completing its mission surveying both the Indian Ocean and Bay of Bengal. After departing from Fremantle, Australia on March 21st, the international team of researchers spent weeks collecting data essential for investigating global changes in ocean physics, chemistry, and biology.

The Growing Impact of ENSO on U.S. Extreme Drought and Flood Events

Extreme hydroclimate events, such as droughts, floods, and heavy rainfall, account for a substantial portion of weather-related disasters in the United States, leading to significant socio-economic losses involving agriculture, water resources, and public health, among others. For instance, from 1980 to 2024, droughts were responsible for approximately $368 billion in economic losses for the United […]

Advancing our understanding of the Atlantic Meridional Overturning Circulation (AMOC)

A pause in the weakening of the AMOC since the early 2010s A recent study by scientists at AOML found that extensive weakening of the Atlantic Meridional Overturning Circulation (AMOC) occurred in the 2000s, but has paused since the early 2010s due to a tug-of-war between the natural and anthropogenic signals.  The AMOC is the […]
