Reassessing the stability of the Florida Current: New insights from 40 years of observations

AOML Communications — Thu, 05 Sep 2024 22:01:32 +0000

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, […]

AOML Researchers Monitor Important Boundary Currents in the North Atlantic Ocean Through Direct Measurements at Sea

AOML Communications — Tue, 06 Jul 2021 20:25:11 +0000

Researchers from the Physical Oceanography Division of AOML conduct regular hydrographic surveys to monitor the western boundary current system in the subtropical North Atlantic Ocean. These cruises are a part of the laboratory’s long-running Western Boundary Time Series (WBTS) project and are designed to monitor both the Florida Current, east of Florida in the Florida Straits, and the North Atlantic Deep Western Boundary Current east of the Bahamas in the North Atlantic Ocean. These western boundary currents are important parts of the Atlantic Meridional Overturning Circulation (AMOC).

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

AOML Communications — Thu, 28 Jan 2021 15:16:22 +0000

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.

October 2015 Western Boundary Time Series Cruise

AOML Communications — Fri, 23 Oct 2015 12:14:03 +0000

AOML oceanographers are participating in a joint research cruise to study the Meridional Overturning Circulation onboard the R/V Endeavor during October 3-20. The team will sail from Fort Lauderdale, FL to collect roughly 55 full-depth conductivity-temperature-depth (CTD) profiles in the Florida Current and the Deep Western Boundary Current east of the Bahamas. The scientists will also work with their partners from the University of Miami to recover, redeploy, and maintain three tall moorings and nine smaller moored instruments during this cruise in support of the NOAA Western Boundary Time Series project and its partner National Science Foundation project.

100th Successful Dropsonde Cruise for the Western Boundary Time Series Project

AOML Communications — Thu, 15 Oct 2015 12:43:10 +0000

In October, AOML scientists, technicians and engineers involved in the Western Boundary Time Series (WBTS) project completed the 100th successful dropsonde cruise in the Florida Current since the project's inception in 2000. The dropsonde cruises measure volume transport in the Florida Current using an out-of-service telephone cable between Florida and Grand Bahama Island.

February 2015 Western Boundary Time Series Cruise

AOML Communications — Sun, 15 Feb 2015 20:38:07 +0000

AOML physical oceanographers Molly Baringer, Ulises Rivero, Pedro Pena, Andrew Stefanick, Grant Rawson, Jay Hooper and Francis Bringas conducted a Western Boundary Times Series cruise aboard the UNOLS R/V Endeavor on February 15, 2015. Molly Baringer, AOML Deputy Director, served as chief scientist and was supported by additional crew from the University of Puerto Rico. Scientists measured full water column values of salinity, temperature, and oxygen. Scientists also telemetered data from a series of moorings along the 26th north parallel for a joint NOAA and National Science Foundation program designed to monitor the Atlantic meridional overturning circulation current. Francis Bringas also conducted a fall rate experiment that consisted of deploying 200 XBTs from different launch heights.
