Sampling stations and experimental conditions.

Characteristics of the different stations sampled for dark size-fractionated assimilation measurements, time of incubation during experiments and radiation doses received by samples in which light experiments were performed.(*) Stations where samples for size-fractionated assimilation were also incubated under different light conditions.(**) Stations where, besides size-fractionated assimilation measurements, incubations for microautoradiographic analysis were carried out.
