Target Species occurrences provided by the EurOBIS (European Ocean Biodiversity Information System). EurOBIS s an online marine biogeographic database compiling data on all living marine creatures. The principle aims of EurOBIS are to centralize the largely scattered biogeographic data on marine species collected by European institutions and to make these data freely available and easily accessible. All data go through a number of quality control procedures before they are made available online [see standards], assuring a minimum level of quality necessary to put the data to good use. postal
