在海洋生物多样性研究中，能够评估数据的质量和完整程度已成为必不可少的条件，特别是在处理通常汇编各种来源数据的大型数据库时。很少有综合数据库在单个记录的层面上提供质量标志，这使得用户很难轻松提取适合其特定目的的数据。本文介绍了不同的步骤，制定了欧洲和国际海洋生物地理信息系统（EurOBIS和OBIS）内的分布记录的质量和完整性进行分析。对记录的数据格式、信息的完整性和有效性、所用分类学和地理标志的质量和细节以及记录是否为推定的离群值进行检查。相应的质量控制（QC）标志不仅有助于用户选择数据，还有助于数据管理团队和数据保管人识别所提交数据中可能存在的差距和错误，从而为提高数据质量提供空间。这些质量控制程序的结果目前可在EurOBIS和OBIS数据库中获得。通过欧洲海洋观测和数据网络（EMODnet生物学）的生物学门户网站，向用户提供了通过这些QC步骤的特定组合的EurOBIS记录的子集。未来，EMODnet Biology将通过其门户网站提供广泛的过滤器选项，允许用户自己进行特定的选择。通过LifeWatch，用户已经可以上传自己的数据，并根据本文所述的质量控制程序进行检查。数据库URL：www.eurobis.org（www.iobis.org; www.emodnet-biology.eu/）
Being able to assess the quality and level of completeness of data has become indispensable in marine biodiversity research, especially when dealing with large databases that typically compile data from a variety of sources. Very few integrated databases offer quality flags on the level of the individual record, making it hard for users to easily extract the data that are fit for their specific purposes. This article describes the different steps that were developed to analyse the quality and completeness of the distribution records within the European and international Ocean Biogeographic Information Systems (EurOBIS and OBIS). Records are checked on data format, completeness and validity of information, quality and detail of the used taxonomy and geographic indications and whether or not the record is a putative outlier. The corresponding quality control (QC) flags will not only help users with their data selection, they will also help the data management team and the data custodians to identify possible gaps and errors in the submitted data, providing scope to improve data quality. The results of these quality control procedures are as of now available on both the EurOBIS and OBIS databases. Through the Biology portal of the European Marine Observation and Data Network (EMODnet Biology), a subset of EurOBIS records—passing a specific combination of these QC steps—is offered to the users. In the future, EMODnet Biology will offer a wide range of filter options through its portal, allowing users to make specific selections themselves. Through LifeWatch, users can already upload their own data and check them against a selection of the here described quality control procedures.
