Here, we have compiled tools that community members have built to access, analyze, and visualize datasets. We hope you find them helpful in advancing your efforts to use OOI data in your work.

Should you have a tool or dataset to share, please contact the HelpDesk. We will get it posted right away so others can benefit from your work and, perhaps, foster collaborative efforts.

Data Status and Data Visualization Tools

OOI Data Team Coastal and Global Array MATLAB toolbox (2020).

This MATLAB toolbox is useful for downloading data via the Machine-to-Machine interface.

Rutgers Data Team QC Database (2018)

This site provides status and data availability information on an instrument and data stream level, as well as a full list of platforms, nodes, streams, and parameters across all arrays. This site is a non-production prototype tool developed for internal use, so data are not guaranteed to be synced continually. Built by the Rutger’s Data Team its purpose is to enable organized quality control testing.

Derived Datasets and Collaborations

Seismometer and Hydrophone Data on IRIS

Data from the OOI broadband and short-period seismometers and low frequency hydrophones at Axial Seamount, Slope Base, and Southern Hydrate Ridge, and bottom pressure sensors in Axial caldera installed between July-October 2014 are available through the Incorporated Research Institutions for Seismology (IRIS). Data may be pulled hourly and are available in a variety of formats. While searching within IRIS for OOI data, use the two-letter IRIS network designator “OO.” Original announcement and more information can be found here.

OOI Glider Data in the IOOS Glider DAC

OOI glider data are now a part of the Glider Data Assembly Center (DAC) resource collated by the Integrated Ocean Observing System (IOOS). As new gliders are deployed, the near real-time data are added to the DAC, while older glider data are available for download, and glider tracks can be visualized using the map viewer.

Cabled Array tilt meter, co-located temperature plots, and inflation forecast

This site, courtesy of Bill Chadwick (Oregon State University/CIMRS), has been updated to add an inflation forecast created by Dr. Chadwick and Andy Lau (Oregon State University/CIMRS). These plots use OOI pressure data to extrapolate the average rate of inflation over the last 12 weeks and calculate the date when level of inflation at Axial Seamount will reach or exceed the pre-2015-eruption level. Note that the average rate of inflation changes with time, and reaching the threshold does not guarantee an eruption, but the volcano is likely to erupt within a year after reaching that threshold. The plots are automatically updated once a day using the latest inflation rate. (edited 05/16/18)

Plot of OOI BPR data from the Caldera Center

Plot of OOI BPR data from the Caldera Center (BOTPT-A301-MJ03F; black curve) showing deflation during the 2015 eruption (left) followed by re-inflation. Blue dashed line extrapolates into the future using the average rate of inflation from the last 12 weeks; middle blue dot is date when 2015 inflation threshold is reached, right blue dot is when a threshold 30 cm higher will be reached.

OOI High Definition video camera system (CAMHD) Python module

This module, courtesy of Timothy Crone (Lamont-Doherty Earth Observatory), provides information about remote CamHD files, or can be used to retrieve individual still frames from these files, without having to download the entire file first. The module is still under development, which should be considered if using it to develop additional code, which also is actively encouraged.

Broadband Hydrophone (HYDBB) Python module

Use this module to convert audio MSEED files from the OOI hydrophones into FLAC or WAV format, filters the data, and creates spectrograms. The module is courtesy of Pete Cable (Raytheon).

Axial Seamount Hydrothermal Vent Time-Lapse Videos

A new computer vision routine, developed by Aaron Marburg (University of Washington, Applied Physics Lab), aided by Timothy Crone (Lamont Doherty Earth Observatory), and Friedrich Knuth (Rutgers University), is able to correctly identify and tag scenes of scientific interest in the CAMHD video stream. These scenes were previously being manually identified by students at Rutgers University. A new set of time-lapse videos has been created with this enhanced metadata record, displaying one frame captured every three hours from November 2015 to July 2016. (edited 09/07/17)

Axial Seamount and Coastal/Slope Biology Catalogs

Here you can view images and video of the many different organisms observed over the years of Regional Cabled Array expedition cruises. The first catalog relates to Axial Seamount, a deep-sea volcano on the Juan de Fuca spreading ridge, and the Coastal catalog contains animals seen at Hydrate Ridge, Slope Base, and Coastal Endurance cabled sites. These archives, compiled by students at the University of Washington under the guidance of Deborah Kelley (University of Washington) and Leslie Sautter, College of Charleston, are designed to be living documents, and will be continually updated to include information from future cruises and additional details provided by experts.

Axial Seamount Earthquake Catalog

This website, courtesy of William Wilcock (University of Washington) provides access to a near-real time catalog of earthquake detections and HYPOINVERSE locations for the Ocean Observatories Initiative cabled observatory at Axial Seamount. Support for this work comes from the National Science Foundation. (added 10/20/17)

Need Help?

The HelpDesk is here to help you figure out and resolve any issues you may have in accessing and using OOI data.

Our first order of business is making sure that users and potential users of OOI data have their questions answered. Whether you are stymied by how to download pCO2 data, looking to ask about how to add instrumentation to an existing array, or wondering how OOI data undergoes quality control, help is but an email or phone call away.

Contact us at We promise to give you a timely response and will strive to answer any and all questions satisfactorily.
