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. 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.

Hamme et al. (2019) Global noble gas and N2/Ar database, version 1.0. These data are a compilation of dissolved noble gas and N2/Ar ratio measurements collected from 1998-2016 in locations spanning the globe.

This database contains the data on dissolved gas measurements published in:
Hamme, R. C., Nicholson, D. P., Jenkins, W. J., & Emerson, S. R. (2019). Using Noble Gases to Assess the Ocean’s Carbon Pumps. Annual Review of Marine Science, 11(1), 75–103. doi:10.1146/annurev-marine-121916-063604

Version 2.0 corrects an incorrect sign in the longitude for cruise 33KI20040814:HOT162 in version 1.0. The error in the database does not affect any figures in the publication.

This data is provided free for educational and non-profit research purposes. We ask that you appropriately cite Hamme et al. (2019) Annual Review of Marine Science in any work that uses this database. Please also send an e-mail to rhamme@uvic.ca, letting her know that you have downloaded the data, so that she can keep you apprised of any further corrections or changes. If you discover what you believe to be an error in the database, it is your responsibility to send an e-mail to me at rhamme@uvic.ca before using the data in a publication.

Both MATLAB .mat databases and comma-delimited .csv text files were provided to BCO-DMO. For the flat, ASCII version (csv) use the \"Get Data\" button on the BCO-DMO metadata landing page. For convenience, the MATLAB file is also provided as a Supplemental File: Global_Hammeetal2019.mat (400 kb)

These two formats contain identical information. Different cruises can be identified by the sequence number, cruisename, or date.

Secondary data - On some cruises, Ar concentration and N2/Ar ratio measurements were performed at two different labs on separate samples, for inter-calibration purposes. In these cases, data from both labs is given separately with data from the second lab labeled \"secondary\".

This data is provided free for educational and non-profit research purposes. Please cite the publication listed under Acquisition Description in any work that uses this database. If you would like to be apprised of any future corrections or updates to the data, send an e-mail to rhamme@uvic.ca. If you discover what you believe to be an error in the database, it is your responsibility to send an e-mail to rhamme@uvic.ca before using the data in a publication.

Both MatLab .mat databases and comma-delimited .csv text files are provided. These two formats contain identical information. The data from the paper is listed in order of collection (date). Different cruises can be identified by the cruise name or date.
