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.

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.

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 […]

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 […]
