A World of Ocean Data at Your Fingertips

OOI data are available for download in many ways to everyone with Internet access.The primary source for the majority of data is OOI’s data portal. There you have access to nearly all the data from the cabled and uncabled arrays, with additional capabilities of plotting and visualizing specific datasets to test hypotheses and answer scientific questions.

Other ways to access OOI data include:

The Raw Data Archive provides access to raw datasets as they are received from the instruments.

The ERDDAP (National Ocean and Atmospheric Administration’s Environmental Research Division’s Data Access Program) Server provides access to downloadable subsets of OOI datasets in common file formats, such as Python, R, Javascript, and MATLAB, with the capability of creating graphs and maps.

An Analytical Data Archive is a repository for processed analytical data and metadata for fluid and particulate samples collected by the Regional Cabled Array instruments.

Access to OOI data is also available through a Machine-to-Machine (M2M) interface, which allows users to request data to meet their needs, from small amounts of data, to multiple data streams or data from multiple platforms, and to set up recurring downloads to update an existing dataset.

CTD casts and water samples are collected during regular operation and maintenance cruises to service each of the five arrays. These Cruise Data are available for analysis and integration into research and teaching materials.

To help expand understanding of OOI data and its potential applications, OOI integrates the computer programming language Python and data processing tool, Jupyter Notebooks, as means to access, share, and visualize OOI data.

If you aren’t certain where to begin, have a look at the OOI data tutorial that gives step-by-step directions on how to use the portal to access OOI data. If you still have questions after watching, the HelpDesk is always available to users and potential users. We are committed to helping you find and use the data you need.
