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

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
Description:

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 hydrosheds.org. Geomatic analyses used an updated, unpublished HydroSHEDS watershed boundaries that are slightly different than those available on hydrosheds.org (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.

Description:

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.

Description:

Underwater video footage collected during June 2013 in Heriot Bay, Quadra Island, British Columbia. This data was collected as part of a study on the impacts of boat noise on a wild fish, Porichthys notatus, and its predators.

This video was produced using underwater cameras: 1) A custom-built Teamed Optic-Acoustic Device (TOAD) for predator-prey component, which consisted of a custom-built underwater camera and a synced hydrophone (HTI- 96-min, High Tech Inc., Long Beach, MS); 2) A Microcam (MVC2120WP-LED, Micro Video Products, www.microvideo.org) for individual midshipman behaviour component. See Sarika Cullis-Suzuki's PhD thesis (http://etheses.whiterose.ac.uk/10526/) for further details on equipment.

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
Description:

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.
