Remotely Operated Vehicle (ROV) Program

Reaching New Depths with Mini-ROVs

The MPA Collaborative Network is launching projects across California using underwater drones. These small, remotely operated vehicles (ROVs) are being used to explore and study marine protected areas along the California coast. Through a partnership with Sofar Ocean and funding from the S.E.E. Initiative, each of the 14 MPA Collaboratives from Del Norte to San Deigo County has received Trident mini-ROVs. With a depth rating of 100 meters and a 3-hour dive time, these ocean exploration tools will help Collaboratives expand outreach projects that have previously been restricted to land or shore and develop opportunities for citizen science, refining research questions and developing needed protocols.

Using Collaborative ROVs

Trident ROVs are shared resources for each MPA Collaborative in the Network and are available for use only by members. If you are already involved with your local MPA Collaborative, just reach out to your Co-Chairs and they’ll help you get started using the ROV. Alternatively, you can also fill out the ROV Check-Out Request Form and your request will be forwarded. Members are asked to attend a Collaborative ROV training before using the Trident ROVs.

Not a member yet? No worries! If you are interested in getting involved with your local MPA Collaborative and having access to resources like the Trident ROVs, reach out to the Co-Chairs to express your interest. Everyone is welcome to join and contribute their expertise to advance MPA management and encourage ocean stewardship at the local level. Contact information for Co-Chairs can be found on each Collaborative page.

Procedure and Requirements for Member Use

1. Attend a Collaborative ROV Training. Members who have not been able to attend a training are asked to work with a member who has. Training videos coming soon.

2. Review the available resources in the Resources section of this page, especially the User Guide and Best Practices, Trip Planning Checklist, Field Data Sheet and Guide to filling it out, and Trident ROV User Manual.

3. Fill out the ROV Check-Out Request form or contact Collaborative Co-Chairs/ROV hosts to schedule time to use the Trident ROV.

4. Ensure Trident and controller are charged and both the software and app are up to date before use. See the manual for details.

5. Explore the underwater world with the Trident! Take video and pictures. Fill out the Field Data Sheet for each expedition (trip). One data sheet can be used for multiple launches in one day.

6. Rinse equipment properly with fresh water and dry thoroughly. See the manual for details.

7. SEND COMPLETED FIELD DATA SHEETS TO nicole@mpacollaborative.org. This is necessary to gather important data and determine best practices for ROV use in MPAs.

8. Upload any ROV footage you’d like to share with the Network to the ROV Video Database with credit information. See the manual for details on how to transfer video from Trident.

9. Share updates on social media. Tag @mpacollaborativenetwork, @sofarocean, #SEEInitiative, #MPATrident.

10. Send pictures, video, and an informational blurb about your trip to nicole@mpacollaborative.org to be featured on MPA Collaborative Network channels.

11. Return equipment to host at the agreed-upon time.

The Technology

Good to Know:

  • Live video is streamed back to the surface via a Kevlar-reinforced tether, then to your device over WIFI
  • Open source – attach custom sensors or modules as add-ons to the payload area
  • Records 1080p @ 30fps
  • Need an android device 5.1 or higher to control the Trident using the OpenROV App
  • Customizable – various control set-ups are supported including virtual reality headsets
