Abstract
    Research trawl surveys from Canada's Department of Fisheries and Oceans (DFO) and the US National Oceanographic and Atmospheric Agency (NOAA) are used as a basis for developing a road-map to prepare research trawl surveys in general for public access via systems such as Ocean Biogeographic Information System (OBIS). Data quality issues associated with surveys includes validation of species names, treatment of zeros, data standardization techniques and provision of confidence limits. Suggestions to improve the OBIS system include support for summary statistics and length classes as well as addition of a gazetteer facility. The Bedford Institute of Oceanography's recently established OBIS provider service is also described.
