The TRACE database is a searchable catalogue of the full range of marine biological resources (from animals to macroalgae, protists, prokaryotes and viruses) that can be provided by the marine stations comprising the EMBRC Research Infrastructure. The catalogue includes living resources that are currently ex situ cultured (model animal and macroalgal taxa, microorganism culture collections), fixed or frozen resources maintained in sample collections, and resources that can potentially be collected from the natural environment upon demand. In the Trace database users can find information on the nature and origin of the resources of interest to them and identify the marine station(s) who can provide the biological resources via on site and/or remote access.
