Integrative Observational Platforms

We focus on observational investigations of ocean physics at a variety of spatial and temporal scales. This requires a wide range of measurement capabilities, from rapidly occupied synoptic, three-dimensional surveys to repeated sections monitored over periods of months or years. Many of the important processes are episodic, occurring over short temporal or spatial scales that require highly adaptive sampling strategies to capture and resolve. Progress in other areas, such as high latitude circulation, may be hindered by difficult access and limited platform endurance. Motivated by these observational challenges, the IOP team works to develop and maintain expertise with a suite of measurement technologies that can be applied either singly or in flexible combinations optimized for particular problems.

We are launching a webinar series to inform the Seaglider user community about the latest available software and piloting tools. Webinars will take place roughly every three weeks and will cover a specific topic through a mix of presentation, demonstration, and Q-and-A. Content will be adapted to meet user needs and feedback. We will kick things off by taking a detailed look at the features of the basestation3 visualization capability and related tools. The first three webinars are scheduled as follows (note that the time of day varies so that those in different time zones have an opportunity to join).

  1. Wednesday May 15, 8-9am PDT (GMT-7): “Vis 101: Visualization features of basestation3”. An overview of the basestation3 / visualization features.
  2. Wednesday June 5, 4-5pm PDT (GMT-7): “Vis 201: How vis can help you pilot”. How to interpret science and engineering plots while piloting.
  3. Wednesday June 26, 8-9am PDT (GMT-7): “Vis 301: Advanced tools and control”. A look at the more advanced vis features including configuration of users and plots, and regression and ballasting tools.

All webinars will use this zoom link: and will be recorded and made available following the event.

The latest version of Seaglider basestation software, Basestation3, has been released under a BSD style open source license. This is the software that we have been testing and demonstrating on our community basestation server,, for the last several months. Software is available on github.

Thanks to all who have responded to our survey about the state of the global Seaglider fleet. If you have not received the survey and would like to stay in touch with us, please drop a note to and we will add you to our future communications. We are also adding more information about our support activities and the current state of development.

With HII’s exit from the Seaglider business, IOP will be expanding our capability to support and propagate Seaglider technology. We are looking for feedback on how we can best support the community. Please see our dear colleague letter for more information. One initial effort will be a January release of basestation v3. Demo and screenshots of the pilot’s index, glider and map tools of the new native visualization and piloting tools now available. New piloting view

Seagliders 180, 219, 220, 237, 247, and 248 have all been recovered, marking the end of S-MODE IOP-1. Looking forward to round two in the spring!
