RRS Discovery: Aboard research ship monitoring impact of climate change
We mostly focus on things getting hotter with climate change. But out in the Atlantic right now, a British research vessel is studying how changes could actually lead to winters getting much, much col...

AMOC in density space, heat and freshwater transports, and 2D velocity fields at 26N have been updated to February 2023. They are freely available on our website at rapid.ac.uk

NOC's Dr Ben Moat (@benmoat.bsky.social) and Dr Tillys Petit feature in the BBC News about the importance of observing the Atlantic Meridional Overturning Circulation (#AMOC). 🌊 www.youtube.com/watch?v=d1bG...

Thats the last of our tall moorings recovered. In the next six months we will calibrate the measurements and then release the next 26N AMOC time series update. @noc.ac.uk

Chris Cardwell is an Electronic Engineer who is working on a prototype remote telemetry system for use on the RAPID moorings and in the wider oceanographic community. Outside of the current expedition, he is found developing novel oceanographic sensors, samplers and observing systems. @noc.ac.uk

Being an RSE isnt always just sitting at your desk. This week I aided in the deployment of the RAPID 26N WB2 sensor mooring for monitoring the change in the AMOC by optimising the tools used to verify and log the sensors going on to the mooring, all whilst aboard RRS Discovery.
A ships crew are working together to lower a float, with multiple sensors attached, into the ocean.

A telemetry system has been deployed on the RAPID 26N WB2 western boundary mooring to enable periodic data updates. @noc.ac.uk

Mobilisation of the RRS Discovery in Fort Lauderdale is complete. We will sail in a few hours to service the RAPID 26N westen boundary mooring array. @nocnews.bsky.social @nocmarinephys.bsky.social

My first research expedition was only 36 years ago, but the ship did then still use a paper chart recorder for bathymetry. i spent many hours watching the chart so that the towed undulating CTD (SeaSoar) did not hit the sea floor!

The RAPID-MOCHA-WBTS time series of the Atlantic overturning circulation will soon reach 20 years (started in 2004) thanks to the many people (crew, officers, students and researchers) who have participated in the research expeditions that regularly maintain the observing array.

In the end, the Gulf Stream is *not* slowing down and the #AMOC ... just marginally. That's fascinating and relevant for climate modeling and the current and future needs for ocean observing! www.nature.com/articles/s41...

Florida Current transport observations reveal four decades of steady state - Nature Communications
The study shows that the Florida Current, an important contributor to the Atlantic Meridional Overturning Circulation, has not declined as previously suggested, but remained steady over the past 40-ye...
