    This dataset is the definitive set of locality boundaries for the state of Victoria as defined by Local Government and registered by the Registrar of Geographic Names. The boundaries are aligned to Vicmap Property. This dataset is part of the Vicmap Admin dataset series.

  • Stations for continuous measurement of hydrological, physical, chemical and sediment parameters have been installed on the Sélune river, as part of the scientific program to monitor the leveling of the Sélune dams. Measurements have been taken on at least an hourly basis since 2014 at the latest. Since 2019, these stations have been part of the Sélune Observatory, which is responsible for monitoring environmental parameters (biotic and abiotic). All stations measure turbidity, water level and conductivity. Some stations measure additional physico-chemical parameters such as pH, dissolved oxygen and chlorophyll concentration. Samples are also taken at upstream (Pont de Virey) and downstream (Pont de Signy) stations, for laboratory chemical analysis. This layer shows the location of flow measurement stations.

  • The spawning grounds of the sea lamprey Petromyzon marinus are located within the perimeter of the Sélune Observatory. As this species is migratory, its colonisation of the Sélune river and its tributaries will probably be influenced by the removal of the Sélune dams. The spawning grounds are characterised by a depression accompanied by a sediment ejection dome immediately downstream. The stones returned to the dome are lighter, making the nests easily visible and identifiable for up to several weeks after spawning.

    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.

    Title: InterActic : A millennium of interaction between societies and environments in Arctic and sub-Arctic regions (Canada and Greenland) Abstract The InterArctic project focuses on vulnerability, resilience and adaptation of northern societies facing global change. The rapid current warming of Arctic and Subarctic climates has already produced many changes in the social, economic and cultural behavior of the populations inhabiting these regions and more changes are expected to come. Few of the changes are considered to be positive or not disturbing the fragile balance between human and the environment. Populations of these areas have to face these challenges, and in this context, looking at the past provides the opportunity to document the complex relationships between climate, ecology and human societies, which may provide deeper understanding into ways of better facing the future. The chronological frame of the project encompasses the last millennium, a well-documented period by both ice core data and historical archives. The study area includes Eastern Canada (Nunavik, Nunavut and Nunatsiavut) and Greenland (South and North). Around 1000 years cal. AD, some of these areas witnessed the meeting between European farmers coming from Scandinavia, and hunters-fishers arriving from Beringia. Today, these two lifestyles are still coexisting, with farming in South Greenland, and hunters/gatherers/fishers in Nunavik, Nunavut, Labrador coast and Greenland. Within these study areas, our aim is to document 1000 years of interactions between Thule/Inuit people, Norse settlers and their environment, through an interdisciplinary approach exploiting different kinds of natural archives. The use of pedo-sedimentary archives (lakes, peat deposits, cryosols, anthrosols) and palaeoenvironmental multiproxy analyses will highlight landscape evolution, climatic and anthropogenic forcings upon ecological processes. Archaeological sites, and more specifically archaeological soils, ecofacts and artefacts, will give precious information about the nature of these interactions. The complementary anthropological/cultural approach will focus on human memory, perception, practices and prospects of environmental and social changes, archaeological heritage and past settlement location choices, of six communities in Greenland and Canada. These issues will be explored in an interdisciplinary work through open interviews and co-design workshops bringing Inuit elders and youth together with project researchers. Coproduced knowledge (blending traditional and scientific), including Inuit visual documentation of the community changes and the writing of science fiction narratives, as well as cognitive maps (Inuit internal representation), will then be shared through innovative educational projects such as an interactive web platform designed to share project results, involving local partners in Greenland and Canada as well as French secondary schools and universities.
