NOAA Scientists Detect a Reshaping of the Meridional Overturning Circulation in the Southern Ocean

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) have shown that the Global Meridional Overturning Circulation (GMOC), commonly known as the global ocean conveyor belt, has changed significantly in the Southern Ocean since the mid-1970s, with a broadening and strengthening of the upper overturning cell and a contraction and weakening of the lower cell. These changes are attributed to human induced ozone depletion in the Southern Hemisphere stratosphere and increased carbon dioxide in the atmosphere. The study also shows that the changes in the Southern Ocean are slowly advancing into the South Atlantic and Indo-Pacific oceans.

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.

AOML Scientists Monitor How Heat and Water are Transported Through the Atlantic Ocean Using Field and Satellite Observations

In a recently published study, scientists at AOML present 28-year long (1993-2020) estimates of the Atlantic Meridional Overturning Circulation (AMOC) volume and heat transports at multiple latitudes by merging in-situ oceanographic and satellite observations. By combining ocean observations with satellite data, they were able to estimate the AMOC volume and heat transports in near real time. These data can be used to validate ocean models, to detect climate variability, and to investigate their impact on extreme weather events.

Scientists at AOML Awarded Ocean Observing Team Award for Western Boundary Time Series Project

NOAA’s Western Boundary Time Series (WBTS) project, alongside partner projects RAPID and MOCHA, have been awarded the inaugural “Ocean Observing Team Award” by The Oceanography Society (TOS). This award recognizes innovation and excellence in sustained ocean observing for scientific and practical applications. The WBTS/RAPID/MOCHA team is recognized for significantly improving our understanding of Atlantic circulation through the breakthrough design of a basin-wide observing system using endpoint measurements to measure the variability of the overturning circulation across wide areas of the ocean. This design provided continuous, cost-effective measurements that led to a transformation in ocean observing and advances in scientific knowledge.

The Argo Program: Two Decades of Ocean Observations

In a recent article published in Frontiers in Marine Science, the history of the Argo program is examined and discussed. The Argo program began in 1998 when a team of international scientists, known as the “Argo Science Team,” proposed the idea for a global array of autonomous floats to obtain temperature and salinity measurements of the upper 2,000 meters of the global ocean. The new array of floats, called Argo, would go on to be endorsed as a pilot program of the Global Ocean Observing System and be used to fill in the large data gaps in ocean observations.
