New study reveals long-term cooling and freshening of the deep Subtropical North Atlantic Ocean, with hints of major shifts to come over next decade An official press release can be seen on the University of Miami Rosenstiel School’s newsroom website. A new study published in Nature Communications, Earth & Environment unveils a surprising new take […]
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 […]
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 […]
Behind every research project at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) are a suite of instruments. Whether descending to depths or weathering storms, these technologies are paramount to oceanic and atmospheric observations. Get to know 12 of these instruments with a new social media series: 12 Days of teKNOWLEDGEy! On the 1st day of […]
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 […]
Tropical cyclones are among the most deadly and costly natural disasters that affect the United States and many other countries each year. This has led the scientific community to prioritize improving tropical cyclone prediction and the understanding of how tropical cyclone activity has changed and will change in the future. In a new study published […]
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 […]
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 […]
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, […]
Adapted from NOAA press release on August 22, 2024 Today, August 22, the 2023 State of the Climate report was released by the American Meteorological Society, showing Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level and ocean heat content all reached record highs in 2023. The international annual review […]
