By Anne-Sophie Fortin August 16, 2022 After the successful calibrations performed yesterday, one of the two Gliders has been deployed today. It will be autonomous and take measurements of water properties, such as temperature, salinity, oxygen, and chlorophyll until its recovery a few days from now. Koordinaten: 52.80255, -51.597367
By Anne-Sophie Fortin August 15, 2022 To measure the ocean circulation, mooring arrays have been deployed since 2014 in the Labrador Sea as part of the OSNAP program (o-snap.org) and are serviced every two years by scientific expeditions like ours. Today we successfully recovered the K8 moorings and the measurements that it took over the […]
…and what your pasta has to do with it… I am frustrated! Heat waves, wild fires, extreme rainfall, floods, droughts and yet people still claim that climate change is not real. Yes, we are doing stuff, but apparently it is not enough, yet. Drastically reducing greenhouse gas emissions alone will not be sufficient anymore to […]
By Anne-Sophie Fortin August 14, 2022 Today was entertaining as Paul, Félix, and Christian calibrated the buoyancy of two Gliders. Gliders are autonomous underwater vehicles using buoyancy to move around. As they can change their pitch, i.e., angle, they can glide horizontally while moving up and down the water column. Calibration of the Glider’s buoyancy […]
By Anne-Sophie Fortin August 14, 2022 As we transit toward the next station with a speed of about 8 knots, we are taking continuous profiles of the upper 100 meters of the ocean. To do so we use a Moving Vessel Profiler (MVP), an instrument measuring temperature and conductivity (from which salinity can be derived) […]
By Anne-Sophie Fortin August 13, 2022 Today we (purposely) throw some scientific instruments overboard, the firsts of many. In the picture, you may see Paula lowering a Hereon Drifter with a rope. A Hereon Drifter is a Lagrangian surface drifter, which means that it follows the water mass where it has been deployed, under the […]
By: Dr Mohammad Heidarzadeh Associate Professor of Civil Engineering at the University of Bath (England) Secretary General of the International Tsunami Commission. Email: mhk58@bath.ac.uk A new study shows that the deadly and global-reaching tsunami generated by the Hunga Tonga–Hunga Haʻapai volcano in January 2022 was as high as 90 m (see Figure 1). The tsunami […]
By Anne-Sophie Fortin Let me introduce to you the scientific crew aboard the M184 Cruise. The chief scientist of this expedition is Johannes who takes care of the general smooth running of scientific activities on board. He can rely on Sunke (also a co-chief scientist), Félix, and Fehmi, the CTD watch leaders, and on the […]
By Anne-Sophie Fortin August 11-12, 2022 The water is still in the harbour by night. Shrouded in what seems like a perpetual mist, the Meteor is waiting patiently. People step aboard the ship in small waves and wash up in their beds, exhausted from their long flights. As the sun rise, the crew finalizes the […]
Meet us at “Tag der offenen Tür” on Sunday, 21 August 2022 from 11 to 5pm.We are looking forward to meeting you in the foyer of building 8.
