Abstract

The study of macro- or micro-algae often requires the collection of samples in the field. In general, sampling is carried out without the possibility of micro- observation. In the best of cases, the location allows the study of live specimens with scientific equipment in a laboratory close enough to the sampling site. However, in remote locations, samples are usually preserved in the field to delay their exploitation. No preservation method is perfect and this can affect the quality of the analysis. Access to digital microscopy in the field to document or confirm the quality of sam- ples is becoming easier. I will present and compare several transportable microscopes, commercial or open source, that can be used in the field for image acquisi- tion, and potentially, quantitative analysis.
