Description 
Summary

The cruise focused on changes in the microbial community structure, dynamics and processes in key biogeomes from the English Channel to the area off the shelf break in the North East Atlantic. It was part of the five year (2001 - 2006) NERC PML Core Strategic Research Project on Microbially Driven Biogeochemistry (MDB). An underway gradient from Southampton to off the Atlantic shelf edge was sampled. Sampling was also carried out at 2-3 comparative stations that covered the winter baseline and onset of a spring bloom, and at PML/MBAs long term time series stations L4 and E1 off Plymouth. A floating drogued buoy was used to track a water mass through the development of the spring bloom and the characteristics of this changing water mass were monitored in a Lagrangian study.
