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.

This borehole hydrogeophysical logging data include optical imaging,acoustic logging,induction and electrical resistivity,natural and spectral gamma radioactivity,fiber optic measurements and multiparameter probe logs.

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

Available data include monitoring data (weather parameters,piezometric levels and pumping flow rates).

This dataset includes vadose zone data (temperature,water content and suction) and flux tower data (air pressure,air specific humidity,air temperature,co2 flux,evapotranspiration,h2o flux,latent heat flux,wind direction,wind speed).

Objectif : Estimer l’abondance relative de micromammifères et leur portage pour certains agents pathogènes transmis par les tiques dans la Zone Atelier Armorique dans le cadre du programme de recherche OSCAR (Outil de Simulation Cartographique à l’échelle du paysage Agricole du Risque acarologique – 2012-2015). Protocole : Pose de 34 pièges INRA sur vingt-quatre lignes de 100 mètres placéesdans différents types de paysage (forêt, lisière de forêt, bocage ouvert et dense le long de lisières de bois ou de haies) puis relevés à 24 et 48heures. Les animaux piégés ont subi une prise de sang puis ont été sacrifiés pour réaliser par la suite des analyses moléculaires sur différentsorganes (détection de Borreliaburgdoreferisl.,Anaplasmaphagocytophylum et Babesiamicroti).
