ABoVE: Alder Shrub Cover and Soil Properties, Alaska, 2019, V2This dataset holds measures of vegetative cover and soil characteristics for sites in interior Alaska, U.S., along the James W. Dalton Highway (Alaska Route 11). The field data were collected during August in 2018 and 2019 to study the expansion of shrub cover, particularly alders (Alnus spp.) in tundra ecosystems and the potential impact of shrubs on soil properties. Samples were measured along t

Field Data on Soils, Vegetation, and Fire History for Alaska Tundra Sites, 1972-2020This dataset, titled the Synthesized Alaskan Tundra Field Database (SATFiD), provides a comprehensive collection of in-situ field data compiled from 37 existing datasets resulting from field surveys conducted at Alaska tundra sites between 1972 to 2020. The data were harmonized prior to being included in this dataset. The variables include active layer thickness, vegetation cover (by plant functio

Extract of data from the sea ice measurements database - 1985-2007These data have been extracted from an Australian Antarctic Data Centre application, "Sea ice measurements database". The application has now been discontinued. The download file contains the extracted data, plus a sample data entry form. The extracted data are simply database tables that have been converted to csv format. Taken from the main page of the application: This archive contains in-situ

Ice-physics transect data obtained during the SIPEX II voyage of the Aurora Australis, 2012This dataset contains in situ measurements of ice thickness, snow thickness, and freeboard along transects on the ice-station floes from the SIPEX2012. Ice cores were collected and snow pits were measured at the 0m, 50m and 100m mark along each transect, where possible. Ice temperature measurements are taken in the field as soon as the ice core sections have been recovered from the core hole. Addi

Habitat surveys of the sea floor at various sites around Davis Station, summer 2009/10Habitat surveys of the sea floor were conducted by divers at sites around Davis Station, East Antarctica, as part of the Davis Sewage Treatment Project during the 2009/10 austral summer (AAS 3217 - metadata parent record = DAVIS_STP). Four non-overlapping and haphazardly placed 25m long habitat surveys were conducted at each site, generally 2 on each side of the boat and at least 10m apart. One di

Locations of nine quadrats used in moss mapping studies at Casey Station, Antarctica 2007-2008The data are comprised of a spreadsheet with locations (latitude and longitude) and labels for moss bed quadrats. The quadrats are located in two sites: Antarctic Specially Protected Area 135 (formerly Site of Special Scientific Interest 16) near Casey Station; and on Robertson Ridge south of Casey. The letter in the quadrant label indicates the vegetation community type: before bryophyte, M for t

Latitudinal Gradient Project - Australian contributionsThis record relates to the Australian component of the Latitudinal Gradient Project. The LGP is largely a New Zealand, US and Italian venture, but a small contribution has been made by Australian scientists. The Australian component of this work was completed as part of ASAC projects 2361 and 2682 (ASAC_2361, and ASAC_2682). Data from this project were entered into the herbarium access database, w

Diatom data for transects at 4 locations in the Windmill IslandsSediment samples were collected from four locations within the Windmill Islands (Cloyd Island, Odbert Island, Shannon Bay and Brown Bay). Within each location three parallel transects were created, with samples taken at set depths along each transect. At the time of collection, both surface and benthic irradiance levels were measured, and the % of surface irradiance that reached the sediment-water
