Data Products
More than 200 unique data products are measured or derived from the nearly 75 models of specialized instruments used in the OOI arrays from the air-sea interface to the seafloor.
Data Product Algorithms
Data Product specifications and data flow diagrams for current data products can be found in the OOI Technical Data Package repository.
The algorithm code used to generate each data product in the OOI Cyberinfrastructure system can be found in OOI ALGORITHMS.
Quality Control
OOI Data Quality Control strives to meet or exceed Quality Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD) standards. In addition to daily human-in-the-loop Quality Control (QC) tests, as data streams are collected, data products are run through six automated QC algorithms. Please see the OOI Data Quality Control page for more information.
