SCIENCE ACTIVITIES / Biological SciencesMarine Fish Division/Invertebrate Fisheries Division Virtual Data Centre– R. Branton (MFD), G. Black (IFD), and J. McRuer (MFD)What is VDCMarine Fish (MFD) and Invertebrate Fisheries (IFD) divisions at BIOand Saint Andrews Biological Station (SABS) provide the scientificfoundation for the DFO Maritimes Region’s finfish and shellfishharvest fisheries management activities. The primary inputs are acomplex array of data from various sources including governmentresearch vessel surveys, industry surveys, fishers’ logbooks, commercialcatch statistics, port samples, and at-sea observers.Recent changes to DFO’s computing culture (adopting softwarestandards and declaring a Science Data Management Policy) haveprompted MFD and IFD to jointly develop an intranet website tofacilitate access to these data. This integrated science user-orientedfacility, otherwise referred to as the ‘Virtual Data Centre’ or VDC, is acompletely new data retrieval and analysis tool. This tool greatlyenhances research productivity by enabling diverse and disparate datasets to appear in common/familiar forms at a central location.The VDC offers a product-oriented approach to data analysisactivities. Data products are produced on demand directly from thedatabase, including a wide range of maps, graphs, reports, spreadsheets,images, and movies.VDC productsData products appear as pre-formed reports or as drop down menusand push buttons, which give the user the option of creating theirown report. These menus provide the ability to specify species names,stock area, survey series, and ranges of years, all appearing in acommon natural language form.Data tables, graphs and maps can be used in presentations orpasted directly into scientific documents.Using VDCThe VDC is accessed using Internet Explorer. Entry is controlled viaa central username/password login page.http://mfdvdc.bio.dfo.caSample line graph - research vessel survey information for Scotian Shelf redfish.New users automatically receive guest status to view pre-formedpublic material. Before viewing private or restricted material orquerying the underlying data, the guest must apply to site or groupadministrators for a username and password. Each groupcontributing to the site controls its own mini VDC consisting of stafflists, project pages, and data pages.Maps can be produced as data movies to facilitate exploration ofspatial and temporal trends within the data or as interactive graphicswhere the area of interest can be enlarged and triggered to provide spreadsheetsand/or detailed statistical analysis of the selected observations.45†UNIT3 REDFISH 4Xpqrs OT3- [Sample Request 38] 2001 April-June48†UNIT3 Redfish UnseparatedSUMMER Stratified Random 2001 Avg.
