First Cruise in Three Years in Support of the South Atlantic Meridional Overturning Circulation Project
After two weeks at sea, the South Atlantic Meridional Overturning Circulation (SAM) project team completed its first cruise since June 2019!
State of the Climate in 2021 Report Released
te of the Climate in 2021 report was released today by the American Meteorological Society, showing greenhouse gas concentrations, global sea levels, and ocean heat content reached record highs in 2021 despite a La Niña event taking place in the Pacific Ocean.
NOAA and Saildrone Launch Seven Hurricane-Tracking Surface Drones
In partnership with NOAA, Saildrone Inc. is deploying seven ocean drones to collect data from hurricanes during the 2022 hurricane season with the goal of improving hurricane forecasting. For the first year, two saildrones will track hurricanes in the Gulf of Mexico.
AOML Celebrates World Ocean Day
The ocean produces at least half of the world’s oxygen, is home to most of Earth’s biodiversity, and is the main source of protein for more than a billion people around the world. It is what makes life on Earth possible not only for humans, but for all organisms on our planet.
Scientists Observe Rainfall Under Tropical Cyclones Reduces Sea Surface Cooling
Tropical cyclones intensify by extracting heat energy from the ocean surface, making the sea surface temperature under storms crucial for storm development. A recent study by researchers at the Pacific Northwest National Laboratory and NOAA’s Atlantic Oceanographic and Meteorological Laboratory found that large amounts of rain under tropical cyclones can reduce the sea surface cooling induced by them.
NOAA AOML Scientists Project Future Changes in ENSO Variability
In a new study published in Nature Communications, scientists at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) investigate the projected changes in the seasonal evolution of El Niño – Southern Oscillation (ENSO) in the 21st century under the influence of increasing greenhouse gases. The study found that global climate impacts on temperature and precipitation are projected to become more significant and persistent, due to the larger amplitude and extended persistence of El Niño in the second half of the 21st Century (2051-2100).
New Research Showing Link between Florida Current and Pacific Ocean could Improve Sea Level, Climate Prediction
A recent study by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) is the first to demonstrate that El Niño-Southern Oscillation (ENSO) temperature variations in the equatorial Pacific Ocean can help predict Florida Current transport anomalies three months later. The connection between Florida Current transport and ENSO is through ENSO’s impact on sea level on the eastern side of the Florida Straits, which plays a dominant role in the Florida Current transport variability on interannual time scales.
Study Explores the Relationship of Anthropogenic Carbon and Ocean Circulation
In a recently published study in Nature Geoscience, scientists at AOML and international partners quantified the strength and variability of anthropogenic (man-made) carbon (Canth) transport in the North Atlantic Ocean. The study found that buildup of Canth in the North Atlantic is sensitive to the Atlantic Meridional Overturning Circulation (AMOC) strength and to Canth uptake at the ocean’s surface.
Ocean Drone Sails into Category 4 Hurricane Sam
For the first time ever, Saildrone Inc. and NOAA have used an uncrewed surface vehicle to collect oceanic and atmospheric data from inside the eye of a hurricane. On September 30th, 2021 saildrone 1045 travelled directly into Category 4 Hurricane Sam.
A world first: Ocean drone captures video from inside a hurricane
Saildrone Inc. and the NOAA have released the first video footage gathered by an uncrewed surface vehicle (USV) from inside a major hurricane barreling across the Atlantic Ocean.
The Saildrone Explorer SD 1045 was directed into the midst of Hurricane Sam, a category 4 hurricane, which is currently on a path that fortunately will miss the U.S. east coast. SD1045 is battling 50 foot waves and winds of over 120 mph to collect critical scientific data and, in the process, is giving us a completely new view of one of earth’s most destructive forces.
