OOI Data

OOI Data Availability

OOI provides free access to a wide range of data collected from around the world’s oceans. We are offering these data in phases. We will offer you greater functionality and more data sets in the coming months based on your feedback. All data are safely archived, and our goal is to get them to scientists and educators as quickly as possible using various delivery mechanism as appropriate.

Learn more about the availability of individual data tools...

1) Cruise datasets for all OOI deployments and recoveries are accessible on the Cruise Data page.

2) The ability to download individual datasets from the data catalog is forecast to be available in early January. Given the high diversity of data the system is collecting, the OOI Data Team is individually evaluating thousands of data streams to insure their quality. All data types will soon be explorable and downloadable by everyone through the Data Portal. Until the data have been fully evaluated, however, users should exercise caution when exploring online datasets. A video tutorial of how to use the Data Portal is also available. Any questions can be directed to the OOI Helpdesk.

3) Large format data from the Cabled Array and cabled components of the Endurance Array, including acoustic, imagery, video and echograms will also be available through the Data Portal.

4) Quick data downloads are available via a THREDDS data server starting with the most popular Essential Ocean Variables and growing over time. (Already prioritized for early 2016 is the installation of an ERDDAP data server.) Data evaluation is a continuous process that has already begun. Any data and associated metadata that have passed the evaluation process will initially be accessible as individual and aggregated datasets, via OPeNDAP and NetCDF Subset Services, provided by the OOI THREDDS data server. A quick-start tutorial on how to use THREDDS is also available. The data team will be sequentially reviewing a prioritized list of data products based on the Essential Ocean Variables (EOVs) and populate an ever-growing list of downloadable data streams. The list will grow each week.

5) Machine-to-Machine Interfaces. Machine-to-Machine interfaces based on secure web services will be made available in Spring 2016.

6) Raw Data Access

Data Quality: Access to the quality control and assurance procedures can be found in the Quality Control documentation. The actual data algorithms can be viewed on GitHub.

Increasing the availability of evaluated data and the diversity of delivery modes will continually evolve based on community feedback in the coming months. You can subscribe to a mailing list to received updates and notification as additional data and functionality becomes available. We also look forward to your feedback as well as suggestions on the tools that would increase the efficiency of synthesizing the diverse data collected by the program.

Over 200 unique data products are measured or derived from the over 800 instruments deployed from the air-sea interface to the seafloor amongst the seven OOI arrays.

The OOI CI provides a common operating infrastructure, the OOI system software (OOI Net), to connect and enable the coordination of operations of the OOI marine components (Global, Coastal, and Cabled Arrays) with the scientific and educational pursuits of oceanographic research communities.  OOI Net permits 24/7 connectivity to bring sustained ocean observing data to a user any time, any place. Anyone with an internet connection can create a login on OOINet and access OOI data.

Additional Information and Policies regarding OOI Data

Community Developed Tools
This page provides users links to resources that community members have built to access, analyze and visualize OOI datasets. If you have a resource you’d like to share, please send a note to the OOI Helpdesk. Please note that these sites are not maintained by the OOI program, as they are supported by outside resources.

OOI Data Usage Policy
OOI data usage policy maintains that the community has open access to all core data. All initially deployed instruments by the OOI team are considered part of the core instrumentation. Any individual can use data from the core instrumentation; there are no constraints on who publishes or how soon.

Data Quality Control
OOI instrument deployment and data quality control procedures were designed with the goal of meeting QARTOD quality control standards. In addition to daily human-in-the-loop QC tests, as data streams are collected, data products are run through six automated QC algorithms.

OOI Observation and Sampling Approach
The purpose of this document is to define how the OOI operates the various in situ sensing elements of the system (sensors and mobile platforms) to ensure the collection of temporally and spatially optimal data and samples that address the overarching science goals of the program.
