The given site contains some of the used methods as laboratory instructions to be downloaded as pdf. They were written for students paractical courses. The language of this material is German (only, so far). A station methods manual is under construction. Language will be English. Note, that nutrients are measured in a continuous flow analyser, not manually. Some methods are still missing (plankton microscopy). Some methods changed recently or will be modified soon. Any user has to ask for the exact information for a specific method and time range. (Spatial Scale Description: UN-ECE.
