Sub meso scale phytoplankton distribution in the North East Atlantic surface waters determined with an automated flow cytometer
Phytoplankton cells in the size range ~1–50 μm were analysed in surface waters using an automated flow cytometer, the Cytosub (http://www.cytobuoy.com), from the Azores to the French Brittany during spring 2007. The Cytosub records the pulse shape of the optical signals generated by phytoplankton ce...
