  • Aboard the R/V Neil Armstrong
    By Bill Johns, Chief Scientist Our cruise is now about halfway through, and spirits are high as we steadily make progress on accomplishing our cruise objectives.  Yesterday the final University of Miami mooring was deployed in the Iceland Basin, completing the turn-around operations on all of the seven moorings deployed along the eastern flank of … Continue reading
  • A Modeler’s First Cruise
    By Daan Reijnders “Well, I’m somewhat of a stowaway here…” This is how I’ve been introducing myself to some crew members in the messroom during dinner or when fetching some late-night cereal. I had never been to the open sea before this cruise. I usually study the ocean from my desk, using models. Some are … Continue reading
  • The night shift
    By Phoebe Hudson It’s 11 pm – time to wake up! I re-open my porthole and it’s now dark outside, with only the whitewash as a contrast against the dark sea background. I stumble around my cabin – getting dressed, brushing my teeth and hair – struggling to tell if I keep bumping into things … Continue reading
  • A new tool to compare models and observations
    A simple Python code that computes the meridional overturning circulation (MOC) from a model dataset interpolated onto the OSNAP section. More information can be found on the o-snap website under the tabs Outreach/For Modelers and the code can be downloaded here.
  • Start of OSNAP East
    by Femke de Jong After four years the University of Miami and Royal Netherlands Institute for Sea Research (NIOZ) teams are once again out at sea together again. Four years ago we were here on the RV Neil Armstrong, together with the UK OSNAP (Overturning in the Subpolar North Atlantic) folks, to recover and deploy … Continue reading
  • Fallen out of time
    By Marilena Oltmanns Tirelessly, full of determination, and with a hint of stubbornness, the ship cleaved its way through the sea. It hadn’t seen land for days and now, in the middle of nowhere, it was hard to believe that anything but ocean existed. As the ship diligently fulfilled its duties, station by station, day … Continue reading
  • Greetings from RSS James Cook! (Part 2)
    By Rita Markina On 15 July, we recovered the first mooring system at the easternmost point of the OSNAP array. A mooring is an anchored system that consists of many instruments at different depths attached to a long wire. It stays in the ocean for many months and helps us to continuously measure ocean properties … Continue reading
  • Greetings from RSS James Cook!
    By Rita Markina The UK OSNAP team left Southampton on 12 July and is heading into the sub-polar North Atlantic. We will be working on the very eastern part of the OSNAP line from the Hebrides shelf via the Rockall basin to the Iceland Basin. This is the region where two major branches of warm … Continue reading

The deadline to … Continue reading
  • OSNAP GDWBC 11 July 2022
    By Ellen Park Life at sea is organized chaos. Each day is incredibly valuable because sea time is so expensive. As a result, prior to stepping foot on the boat, we had a detailed schedule outlining what operations, like mooring recovery/deployment or a CTD cast, would be completed on each day and their duration in … Continue reading
