One of the key features of the OOI Data Portal (also known as OOI Net) is that it processes data requests “on-demand.” This means that the system converts raw data into a processed dataset using the latest algorithms and calibration data whenever you request a dataset.

Generally, this happens quickly. When you make a request to download data you typically should receive an email within a few minutes. However, if you request a lot of data (a year or more), and especially when you request data from from high-resolution instruments (including BOTPT, MOPAK or recovered Glider datasets), it can take much longer for your dataset to be processed, sometimes several hours.

If you haven’t received an email after a reasonable amount of time, there are a few things you can check:

1) Check your spam or junk folder

Sometimes, emails from the OOI data portal get flagged as spam by aggressive email filters. Notifications are sent from the email with the subject [AUTO] OOI Message Service. If this happens to you, please try adding this email address to your browser’s whitelist of safe addresses.

2) Make sure you are logged in correctly

We are currently aware of an issue that prevents users from logging in correctly when they use their email address to log in (instead of CILogon), and they log in on a page other than the homepage (like the data stream catalog page).

Specifically, if you’re not logged in properly, you will notice the Login item in the navigation bar remains instead of changing to your email address. In addition, while the download buttons may become active when you login on the data catalog page, when you click on them, the download dialog box will not have your email address filled in automatically, which it should.

Our developers are currently looking into the issue. In the meantime, the workaround is to simply login on the homepage before accessing the data catalog.

3) Look for the status of your dataset on the THREDDS Server

Finally, you can check the THREDDS server to see if your data request is still in process. If you have received requests in the past, you can tweak the link to show you the catalog for all of your requests, by simply adding “catalog.html” right after your username.

For example, change

Any data requests you have made to the system (that have not yet been purged) should be available via this link. If a request is complete, it will contain status.txt and status.json files that contain the word complete. Requests that are still in progress or were unable to complete will state that (along with error code information), and may or may not yet have data files available.


If you investigate all three of these options and have still not received your data, please contact the HelpDesk ( and let us know a) your username, b) what platform, instrument, and time range you were attempting to download, and c) when you sent your request.
