Ziel der Reise / Objectives of Cruise:

The purpose of Cruise 176 of RV VALDIVIA was to investigate a hypothesised relationship between oceanic convection and phytoplankton dynamics in winter in the open ocean. The mechanism which in spring reliably initiates a plankton-bloom in the open ocean remained in the dark up to now. How can sinking plankton in a deep water column get back to the sea surface to initiate a bloom?
