REPHY (Observation and Monitoring Network for Phytoplankton and Hydrology in coastal waters) is a network implemented by Ifremer. The data acquired by REPHY have been banked since 1987 in the Quadrige database. This manual is intended for users of REPHY data, which are made available on the internet from SEANOE. The Quadrige database is a component of the French Water Information System and its mission is to manage and exploit data from numerous coastal monitoring networks. SEANOE (Sea scientific open data publication) is a publisher of scientific data in the field of marine sciences. The REPHY dataset available in SEANOE makes available all REPHY data for the French metropolis, for years prior to the current year, in the form of fixed files, with an annual update. The dataset is associated with a DOI: http://doi.org/10.17882/47248.

This manual is intended to improve the understanding of REPHY data for best use. It explains for example the fields present in the files, gives indications on the way the data were entered, and provides the elements to be taken into account for the treatment of these data.
