Operational Data Management

Operational data management aboard the NOAA Ship Okeanos Explorer presents an optimal example of end-to-end data management, as defined by National and NOAA policies and international standards and as implemented by the OER data management task force.

This exemplar is the result of the unique relationship aboard the ship which relies on the close alliance between the exploration mission objectives and the ship’s unique capabilities. On the Okeanos Explorer, data management marries with telepresence technology to ensure rapid, standardized management of exploration data assets.

  • SBRS graphicThe shipboard repository server (SBRS) gathers data from shipboard acquisition systems into a standard data file structure, using standard file naming conventions. ‘Warehousing’ the data in this way enables optimization of data quality assurance and documentation processes, and supports rapid data throughput to data centers for preservation and stewardship.
  • A subset of data and information products created on the ship are moved from ship to shore via the ship’s satellite connection to a shore-side repository server (SRS) which mirrors the SBRS. The SRS supports near real-time access to data for shoreside science participants, and public access to a subset of data and products through the Okeanos Atlas and the oceanexplorer website.

Multidisciplinary scientific data sets have been fully managed since the ship’s commissioning in 2008. All exploration data assets collected during ocean exploration expeditions aboard the Okeanos Explorer are fully publicly available in the OER Digital Atlas. When the ship is underway, the Okeanos Atlas provides near-real time access to information about the ship’s data collections activities.
