Bottlenecks – part II (read part I here) In our final blog we will re-capture our journey through the Mediterranean as it is not very often that one gets to travel from one end almost to the other. The Mediterranean is unique because of its numerous passages and straits. These maritime bottlenecks also characterized our […]

Oceanographic pioneer Maurice Ewing is reported to have advised his students that the key to discovery is to take a new instrument to a place where no one has explored before. The midwater research conducted off the Cape Verde Islands during Poseidon Cruise 520 is a fine example of that research philosophy. The unique combination […]

by Nuno Vieira (INDP) During POS520 I help my German colleagues to collect environmental data with a CTD and water sampler rosette. I filter seawater samples taken in different depths to determine its oxygen content, and I assist in operating the Microstructure Probe which is used to profile the vertical current structure of the ocean.
