Ziel der Reise / Objectives of Cruise:

RV POSEIDON expedition P451-2 was scheduled for 24 April - 1 May 2013 (Portim?o - Lisbon) and was organised by MARUM (Bremen). The aim of this cruise was to offer MARUM-GLOMAR PhD-students the unique opportunity to receive specialist, hands-on training in a shipboard research environment. Conventional sediment sampling gears, such as a giant box corer and a Van-Veen grab sampler were deployed to collect surface samples, and a gravity corer to retrieve long sediment sequences. The main objective of the practical training (supplemented by seminars) was to show the participating students the basic principles of the workflow on board a research vessel, beginning with the selection of sampling sites, the handling of sampling gears, the preparation of sediment samples, and finally their description and documentation. In addition, the students contributed to the cruise report and prepared a daily cruise blog for the public audience. Sampling during RV POSEIDON cruise P451-2 concentrated on two seabed structures (Pipoca mud volcano, Anastasya escarpment) in the "El Laberinto" fluid venting area, which is located on the upper slope of the SW Iberian margin.
