BLOG Beitrag 2: SO297

+++english version below+++ Nachdem das erste 2D-Profil nun abgefahren und die Ozeanbodenseismometer (OBS) und Hydrophone (OBH) wieder an Deck eingeholt waren, fuhren wir in das Gebiet für das zweite Experiment. Bei einem Profil werden Geräte in einer geraden Linie auf dem Meeresboden ausgesetzt. Anschließend wird das Profil mit Luftpulsern einmal abgefahren und die Signale werden […]

Station K1 – Mooring Deployment

This week, we recovered, serviced, and redeployed the last mooring of our cruise, the K1 mooring. This mooring measured continuously temperature and salinity in the central Labrador Sea since the early 1990s. More recently, oxygen sensors have been added to the uppermost part of the mooring. Measuring oxygen in the central Labrador Sea is quite […]

Underway CTD

By Anne-Sophie Fortin As we transit at full speed (10 knots) in the Labrador Sea, we used the underway CTD (uCTD) to investigate the vertical structure of potential eddies identified from satellite imagery. The uCTD is a good compromise between research time, efforts, and the dataset we get from it. Indeed, the ability to get […]

Eddy Survey

By Anne-Sophie Fortin August 24-26, 2022 If the marine life would have weather forecasts, they would have eddies maps. Eddies are circular currents of tens to hundreds of kilometers in diameter and a lifetime of about a month. They can be seen on satellite imagery as minimums and maximums of sea surface heights and sea […]

Argo Float Recovery Near Greenland

By Anne-Sophie Fortin Over the past 20 years, Argo floats have caused a small revolution in the field of observational oceanography as they provide near real-time measurements of the ocean subsurface, which have greatly improved our weather forecast and ocean analysis. Currently, there are ~4,000 floats sampling the oceans year-round. These floats are autonomous underwater […]
