Australia to Thailand: I09N GO-SHIP Cruise Completes Voyage

AOML Communications — Wed, 28 May 2025 14:44:32 +0000

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

AOML Communications — Tue, 25 Mar 2025 13:47:21 +0000

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)

AOML Communications — Wed, 22 Jan 2025 17:32:15 +0000

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 […]

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

AOML Communications — Wed, 11 Dec 2024 16:20:44 +0000

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 […]
