A database interface has been developed to provide information about the physical properties of blast waves produced by propane explosions. The user of the Interface can input the mass or volume of propane, and the ambient atmospheric pressure and temperature. The physical properties output by the interface can be displayed as the peak values immediately behind the incident shock as functions of distance; as time histories at selected radii, and as wave profiles at selected times after detonation. The results are based on analyses of the measurements of the blast wave produced by a 20 ton TNT equivalent explosion of a surface-burst hemispherical stoichiometric propane/oxygen mixture (Dewey, 2005; Dewey & Dewey, 2014). The outputs from the interface were evaluated by comparing them with measurements of the blast waves generated by a series of 644 mg stoichiometric propane/oxygen explosions (Sochet & Maillot, 2018). The following physical properties are provided by the Interface: time of arrival of the primary shock; shock Mach number; hydrostatic overpressure; dynamic pressure; overdensity; density; particle velocity; temperature; reflected overpressure; total overpressure; energy density; work density; energy flux, and work flux. These properties are displayed relative to the ambient atmospheric conditions, and in SI units. A Users’ Guide describes how to use the Interface.

This dataset contains three types of data associated with Gasbarro et al. (2018) Marine Ecology Progress Series, collected from remotely operated vehicle imagery surveys in Douglas Channel, British Columbia, Canada. Biological data (i.e. animal abundance and size measurements) from photoquadrats, ROV/water column data (e.g. temperature, depth, dissolved oxygen, etc.) from four dives, and seasonal along-channel current data from a year-long deployment of two moored Acoustic Doppler Current Profilers comprise the three data types. Data was collected as part of an MSc thesis (Gasbarro).

University of Victoria Herbarium Specimen Databaseby Allen, Geraldine A.; Anthony, Wendy.

This data set contains Darwin Core descriptions of the specimens held in the University of Victoria Herbarium. About 1/5 of the total specimens are recorded here.

DOI: 10.18357/Herbarium.2016.data01

The UVic collection includes vascular plants (~50,000 specimens), bryophytes and lichens mainly from British Columbia (especially Vancouver Island), but also from nearby areas including Washington, Oregon, Idaho, Alberta, and the Yukon. The collection houses a large collection of North American asters (Asteraceae), especially the genera Eucephalus and Symphyotrichum. Special collections include those of Arctic plants (Dewline Collection), lacustrine aquatics and macrophytes and marine algae.

The collection is an important resource for education and scientific research and receives wide use through loans solicited from researchers and institutions around the world, as well as researchers at UVic. Researchers have used UVic specimens to study genetic relationships among plants, species variation and plant phylogeography. This research has contributed to numerous publications. The specimens are classified using the Darwin Core metadata standard.

Global volume and distribution of modern groundwater: groundwater age transport modeling results (data)by Gleeson, Tom ; Befus, Kevin; Jasechko, Scott; Luijendijk, Elco; Cardenas, M. Bayani

The authors combine geochemical, geologic, hydrologic and geospatial data sets with numerical simulations of groundwater and analyse tritium ages to show that less than 6% of the groundwater in the uppermost portion of Earth’s landmass is modern. We find that the total groundwater volume in the upper 2 km of continental crust is approximately 22.6 million km3, of which 0.1–5.0 million km3 is less than 50 years old. Although modern groundwater represents a small percentage of the total groundwater on Earth, the volume of modern groundwater is equivalent to a body of water with a depth of about 3 m spread over the continents. This water resource dwarfs all other components of the active hydrologic cycle. For each continent, we present the geomatic assignment of hydrologic parameters and the resulting simulation-based modern groundwater equivalent (D_eq50) for the purely geomatic assignment of parameters, an estimate pairing models to watersheds using groundwater recharge and strict lithology control, and an estimate using recharge and strict water table gradient control. These files have a 2 letter acronym for the continent/landmass followed by _globalws_results_Gleesonetal_NatGeo.csv. The corresponding watershed data can be downloaded at Geomatic analyses used an updated, unpublished HydroSHEDS watershed boundaries that are slightly different than those available on (Bernhard Lehner, personal communication 2014). Therefore, in the data presented here, we used a spatial join to assign the modeling results and geomatic data to the currently downloadable HydroSHEDS zeroth-level watersheds. Nearly all of the watersheds were very similar in extent, however a variable small percent (< 0.1%) of watersheds in each continent were not located in the currently downloadable HydroSHEDS data.

The lack of robust, spatially distributed subsurface data is the key obstacle limiting the implementation of complex and realistic groundwater dynamics into global land surface, hydrologic, and climate models. We map and analyze permeability and porosity globally and at high resolution for the first time. The new permeability and porosity maps are based on a recently completed high-resolution global lithology map that differentiates fine and coarse-grained sediments and sedimentary rocks, which is important since these have different permeabilities. The average polygon size in the new map is ~100 km2, which is a more than hundredfold increase in resolution compared to the previous map which has an average polygon size of ~14,000 km2. We also significantly improve the representation in regions of weathered tropical soils and permafrost. The spatially distributed mean global permeability ~10-15m2 with permafrost or ~1014m2 without permafrost. The spatially distributed mean porosity of the globe is 14%. The maps will enable further integration of groundwater dynamics into land surface, hydrologic, and climate models.

Mapping permeability of saturated terrestrial lithologies over the surface of the Earth (data)by Gleeson, Tom; Smith, Leslie; Moosdorf, Nils; Hartmann, Jens; Durr, Hans; Manning, Andrew; van Beek, Ludovicus; Jellinek, A M

Auxiliary Materials for ‘Mapping permeability over the surface of the earth’ [Gleeson et al.] Table S1 is a compilation of horizontal intrinsic permeability, vertical anisotropy and horizontal unit length from peer-reviewed, calibrated models with hydrolithologic units that are >5 km in length with a shallow upper contact (< 100m depth). We compiled two-hundred and thirty hydrogeologic units from calibrated models which are grouped into seven hydrolithologic categories.

The spatial distribution of subsurface parameters such as permeability are increasingly relevant for regional to global climate, land surface, and hydrologic models that are integrating groundwater dynamics and interactions. Despite the large fraction of unconsolidated sediments on Earth’s surface with a wide range of permeability values, current global, high-resolution permeability maps distinguish solely fine-grained and coarse-grained unconsolidated sediments. Representative permeability values are derived for a wide variety of unconsolidated sediments and applied to a new global map of unconsolidated sediments to produce the first geologically constrained, two-layer global map of shallower and deeper permeability. The new mean logarithmic permeability of the Earth’s surface is 12.7 ± 1.7m2 being 1 order of magnitude higher than that derived from previous maps, which is consistent with the dominance of the coarser sediments. The new data set will benefit a variety of scientific applications including the next generation of climate, land surface, and hydrology models at regional to global scales.

These data include biological (i.e. animal counts) and environmental data from three remotely imagery surveys in Saanich Inlet, a fjord incising Vancouver Island, British Columbia, Canada. All three dives occurred in 2016. Data are organized by row, with each row representing a second of ROV video with metadata related to the ROV dive, water column data (e.g. temperature, salinity, dissolved oxygen, etc.) and species data (animal counts or binary presence/absence tallies). Data was collected as part of an MSc thesis (Gasbarro) and a Canadian Healthy Oceans Network II project (2.1.3).
