[résumé à traduire en anglais] Jeu de données (observations, prélèvements et analyses) sur les bois flottés, issus de la campagne de terrain de 2019 sur le site n°16, South Aulatsivik (HdCi_20). En 2019 (contrairement à 2018), chaque prélèvement a fait l'objet d'un point GPS; la méthode des quadrats n'a pas été utilisée en 2019 pour la localisation des driftwood. Observations: volume, forme, état de conservation, photographies [liste des photos, à voir avec Y.Rantier]. Prélèvements: La numérotation des prélèvements de 2019 sont numérotés de 200 à 255. L’échantillonnage de 2019 est un complément de celui de 2018 (pas réplicat). La localisation est distincte. Le N° 20 avait été oublié en 2018. Analyses prévues: identification taxonomique, dendrochronologie, géochimie, C14 (pour les 'VDR'), [...].

Groundwater comprises approximately 30 percent of the Earth’s total freshwater, serving as a vital resource for both humans and ecosystems. As an essential source of drinking water for humans and sustenance for vegetation, groundwater plays a key role in the terrestrial water cycle. It acts as a buffer, enabling adaptation to climate variability and extreme events like floods and droughts. Therefore, understanding groundwater storage is important for both ecological and15 societal reasons.

Les observations et les prélèvements (tranches/galettes de bois) sont organisés selon des quadrats [protocole à compléter si nécessaire]; la liste des points définissant ces quadrats se trouve dans le fichier 'Note_terrain_Nain_2018.xls'; ainsi que la liste des bois (échantillons) 'Récolte driftwood selon quadrats'. [localisations géographiques à revoir avec resp. projet]. Observations: volume, forme, état de conservation, photographies [à revoir avec resp. projet]. Prélèvements: a priori 111 échantillons 'bois' ('Driftwood'), plus quelques (3?) 'Old Driftwood' [à vérifier, carnet de terrain]; localisés au Canada.

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

During National Science Week on Sunday 26th August 2007, Geoscience Australia opened its doors to the community to showcase a diverse range of work activities. Members of the public had the opportunity to discover how earthquakes are detected, pan for gold, tour the building, view Australia in 3D, become a seafloor detective and talk to the people who work for Australia's national geoscience research organisation. The photographs of that open day have been converted into thumbmail images and are available on the GA web site.

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
