BOA is the result of collecting together the majority of global high-quality buoy and shipboard deepwater hydrographic cast data. It is built on the NOAA/NODC World Ocean Database (BOA06 uses WOD01), WOCE WHP3, Argo, TAO, CSIRO and NIWA archives, and a number of other sources. The component datasets of BOA are stored separately in a range of formats since the nature of these datasets is quite varied. This approach allows easy updating of components (for example, the Argo subset is completely renewed every couple of months.) Where the same data could reside in multiple datasets, those datasets are duplicate cross-checked after any updates (scanning only on the basis of time and location, not the enormous task of searching for duplicated property profiles.). BOA is available in a packaged form of one netCDF file per property (created in July 2006.) Neutral density profiles are also computed and stored in file gamma_BOA06.nc. These files are available via an OpenDAP server and for internal use as local netCDF files.

BOA数据集整合了全球绝大多数高质量浮标与船载深水水文剖面观测数据。该数据集基于美国国家海洋和大气管理局/国家海洋数据中心（NOAA/NODC）世界海洋数据库（BOA06版本采用WOD01）、世界海洋环流实验水文计划第3期（WOCE WHP3）、阿尔戈（Argo）浮标计划、热带大气海洋（TAO）锚定浮标阵列、澳大利亚联邦科学与工业研究组织（CSIRO）以及新西兰国家水与大气研究所（NIWA）的档案数据及其他多个数据源构建而成。由于各组分数据集的属性差异显著，BOA的组分数据以多种格式分别存储。这种存储模式便于对各组分数据进行更新维护——例如阿尔戈子数据集每两个月即可完成一次全面更新。若同一观测数据可对应多个组分数据集，则在每次更新后会对这些数据集开展重复数据交叉核验：仅基于时间与空间坐标进行扫描，而非开展耗时巨大的属性剖面重复检索工作。BOA以按属性分类的单文件打包形式提供，每个属性对应一个网络通用数据格式（netCDF）文件（该打包格式创建于2006年7月）。此外，还会计算中性密度剖面并存储至gamma_BOA06.nc文件中。上述文件可通过开放数据访问协议（OpenDAP）服务器获取，同时也可作为本地网络通用数据格式文件供内部使用。
