    The Ploemeur-Guidel observatory (Britanny, France) is focusing on surface-depth relationships in a fractured crystalline geological context and oceanic climate. It is built on 2 sub-sites, one highly anthropized, the other in natural state. In Ploemeur, groundwater has been pumped since 1991, supplying more than 1 million m3 of clean drinking water annual at a sustainable rate. Such high productivity is explained the specific fractured network in granite and micaschists, draining deep geological layers (~400 m). Extracted water quality is very good, with limited nitrate concentration, in a region that has been strongly affected by widespread pollution. Guidel site is in a similar, but natural context. Deep iron-rich groundwater is upflowing, creating surface and deep groundwater-dependent ecosystems, and feeding a classified coastal wetland. Both sites have a very dense equipment to study rapid to long-term surface-depth exchanges: a flux tower, unsaturated zone monitoring, a network of ~50 shallow (<10m) and deep boreholes (>80m), hydrochemical, temperature and deformation. An well-characterized fractured experimental site offers the possibility to conduct experiments to test innovative instruments and develop new methodologies

    This is a data set on some morphological and physiological impacts of salinity on two isolated of Microcystis aeruginosa performed in laboratory experiments in the spring of 2022. Two non axenic isolated colonial Microcystis aeruginosa strains (PMC1323.21 and PMC1262.20) were used for the experiments. Both strains were provided by the Paris Museum Collection (PMC). For these experiments, colonies of both strains were grown in BG11 medium in Erlenmeyer flasks and kept in an exponentially growing phase. The batch cultures were stored in a growing chamber at 22 °C and under a light intensity of 40 μE/m2/s with a photoperiod of 14h/10h. For details see Bormans et al 2023 in MicrobiologyOpen This data set contains the following sheets: read_me cell_diameter_strain_1323.21 cell_diameter_strain_1262.20 volume_colonies_7d_strain_1262.20 volume_colonies_3d_strain_1262.20 autofluorescence 1323.21 autofluorescence 1262.20 intercellular spacing 1262.20
