The Gulf Stream is widely accepted as playing a pivotal role in the climate system through its transfer of heat, which ultimately supplies heat to northern latitudes in the North Atlantic. What remains less well understood is how the Gulf Stream influences the climate system by transporting nutrients and carbon. These materials stimulate plankton growth, which in turn play a vital role in taking up carbon dioxide…
Two years after their first mission, the C-Streams team returns to the Florida Straits to collect three moorings. Tethered to the sea floor, these moorings carry sensors measuring temperature, salinity, oxygen, nutrients and carbon at depths between 400 and 700 m.

In July 2025, UK and US colleagues returned to the Florida Straits to recover the suite of biogeochemical sensors deployed the previous summer. Working from the research vessel R/V F.G. Walton Smith, the team successfully retrieved instruments measuring pCO₂, pH, nitrate, temperature, salinity, oxygen, and ocean currents (ADCP) from the deep waters at the beginning of the Gulf Stream.
This latest recovery marks the completion of a…
In June-July 2024, C-Streams colleagues from the UK and the US completed a successful field campaign in the Florida Straits to collect instrumentation deployed at the very start of the Gulf Stream. The team travelled out of and into Miami to recover a suite of deep‑water biogeochemical sensors measuring pCO₂, pH, nitrate, temperature, salinity, oxygen, and ocean currents (ADCP) that had been in the water since the previous year.

The Gulf Stream transport of water through the Florida Strait has slowed by 4% over the past four decades, with a 99% certainty that this weakening is more than expected from random chance, according to a new study co-led by C-Streams’ Lisa Beal.

The team took to the RV Walton Smith in August 2023 to deploy the three Florida Straits moorings and release the biogeochemical profiling floats and autonomous gliders that will track the changing characteristics of the Gulf Stream as it progresses northwards
