Breaking records in the sky and sea: Innovations in research through the 2025 Atlantic hurricane season

The 2025 Atlantic hurricane season has officially come to an end. Throughout this record-breaking season, NOAA scientists conducted innovative research on tropical cyclones that will improve forecasting accuracy, enhance understanding of storm behavior, and strengthen preparedness efforts for communities. Their work and dedication contributed to a safer and more resilient future for those facing the impacts of extreme weather events.

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.

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.

Argo, the ‘crown jewel’ of ocean observing systems, turns 25

Originally published on noaa.gov on December 11, 2024. Somewhere in the middle of the ocean, a merchant mariner lowers a cylindrical robotic ocean observing instrument from a ship into the sea to record ocean temperature and salinity. Another instrument is deployed from a plane into the eye of a hurricane to take the pulse of […]

West-east near-surface current trend between 1993-2022. The blue colors show increased westward currents; red colors show increased eastward currents. The largest trends are observed in the central tropical Pacific Ocean (black box). Current velocity data from three equatorial moored buoys (yellow diamonds) provide a subsurface view on long-term upper-ocean current velocity trends.

Study reveals acceleration in Pacific upper-ocean circulation over past 30 years, impacting global weather patterns

An official press release can be seen on the University of Miami Rosenstiel School’s newsroom website. A critical ocean layer for El Niño–Southern Oscillation (ENSO) dynamics. A study published October 31, 2024, in the Journal of Geophysical Research: Oceans has revealed significant acceleration in the upper-ocean circulation of the equatorial Pacific over the past 30 years. This […]

Reassessing the stability of the Florida Current: New insights from 40 years of observations

There is growing scientific interest in quantifying how large-scale ocean circulation is evolving as part of a changing global climate. Of particular interest is the potential weakening of the Atlantic Meridional Overturning Circulation (AMOC).  However, the strength of the Florida Current, a key component of the AMOC, has remained stable for the past four decades, […]
