Synergy of In Situ and Satellite Ocean Observations in Determining Meridional Heat Transport in the Atlantic Ocean

Dong, S., Goni, G., Domingues, R., Bringas, F., Goes, M., Christophersen, J., & Baringer, M. (2021). Synergy of In Situ and Satellite Ocean Observations in Determining Meridional Heat Transport in the Atlantic Ocean. Journal of Geophysical Research: Oceans, 126(4), e2020JC017073.

Abstract: The Atlantic meridional overturning circulation (AMOC) is an oceanic conveyor belt that transports large amounts of heat northwards throughout the Atlantic Ocean. Variations in the heat carried by the AMOC have pronounced impacts on regional and global extreme weather (hurricanes, heat waves, monsoons, etc.), climate, and sea level. Because of its importance, several efforts from the international community are underway to monitor the AMOC at a few latitudes based on in situ oceanographic instruments. The majority of these estimates, however, only span over relatively short and recent time periods…

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.

Remote Impact of the Equatorial Pacific on Florida Current Transport

Dong, S., Volkov, D. L., Goni, G., Pujiana, K., Tagklis, F., & Baringer, M. (2022). Remote Impact of the Equatorial Pacific on Florida Current Transport. Geophysical Research Letters, e2021GL096944.

Using in-situ and satellite observations, this study is the first to demonstrate that ENSO temperature anomalies in the equatorial Pacific force Florida Current transport (FCT) anomalies 3 months later.  The connection between FCT and ENSO is through ENSO’s impact on sea level on the eastern side of the Florida Straits, which is associated with anomalous oceanic convergence/divergence in the Caribbean region and the Bahamas forced by ENSO-induced wind stress curl changes. This established relationship gives some predictability of the Florida Current transport and coastal sea level changes with a 3-month lead time, which can benefit coastal communities, particularly during strong El Niño and La Niña events.

Researchers and Forecasters Team Up to Improve Forecasts in the New Hurricane and Ocean Testbed

After a year and a half of concerted effort between NOAA’s National Hurricane Center (NHC), Atlantic Oceanographic and Meteorological Laboratory (AOML), and other NOAA offices, including the Weather Program Office, the Hurricane and Ocean Testbed (HOT) has been successfully launched in the newly designed William M. Lapenta Laboratory, named in memory of the late director of the National Centers for Environmental Protection. This testbed establishes a physical and virtual collaboration space for researchers and forecasters.

River Runoff Creates a Buffer Zone for Ocean Acidification in the Gulf of America

A new study by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and Northern Gulf Institute (NGI) has revealed the alkalinity of river runoff to be a crucial factor for slowing the pace of ocean acidification along the Gulf of America’s northern coast. This valuable, first-time finding may be indicative of ocean carbon chemistry patterns for other U.S. coastal areas significantly connected to rivers.
