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 […]

Sailing into science: Collaborative cruise exposes students to oceangoing research

Over the past few months, the University of Miami’s Rosenstiel School of Marine, Atmospheric, and Earth Science has conducted three FLOTSUM, i.e., Florida Ocean Time Series by Undergrads at UM, cruises aboard its research vessel the F.G. Walton Smith. FLOTSUM day cruises are conducted five times per year in the Florida Straits for training purposes […]

The Atlantic Meridional Overturning Circulation is weakening in the deep sea of the North Atlantic Ocean, study finds

Just in! A new study, which analyzed mooring observations and hydrographic data, found the Atlantic Meridional Overturning Circulation (AMOC) abyssal limb in the North Atlantic has weakened over the past two decades contributing to sea level rise in the region.

New Mapping Method Uses Sustained Observations to Estimate AMOC at 22.5°S

Changes in the Atlantic Meridional Overturning Circulation (AMOC) and its transport of heat can affect climate and weather patterns, regional sea levels, and ecosystems. A new study led by Ivenis Pita, a University of Miami PhD student working at NOAA’s Atlantic Oceanographic and Meteorological Laboratory/ the Cooperative Institute of Marine and Atmospheric Studies (CIMAS), is the first to estimate the AMOC and heat transport at 22.5°S in the South Atlantic, demonstrating the importance of sustained in situ observations to monitor the state of the AMOC.
