Ziel der Reise / Objectives of Cruise:

On 5 May "Victor Hensen" departed Las Palmas for the third leg during this year's Canary Island cruise. Research was conducted for two projects, the European time-series station ESTOC, and the EU programme CANIGO (MAST III). During this leg, we conducted an intensive sampling program at the time-series station ESTOC, including the monthly sampling for the month of May. Also, different free-floating particle trap arrays were tested. We also carried out experiments onboard ship (dilution experiments as well as O2-incubations) to determine phytoplankton growth rates. Furthermore, we conducted water column sampling along the islands of Lanzarote and Fuerteventura to check for island generated biomass increases, and westward towards the Maroccan upwelling region to check for upwelling generated influences on the region.
