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 […]

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 […]

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 […]

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.

For instance, from 1980 to 2024, droughts were responsible for approximately $368 billion in economic losses for the United […]
