A mission to protect oceans monitors ships’ AIS from satellites

In February, a Vietnamese ship entered Indonesian waters, likely fished illegally, and then returned to port without consequence.

By March, it was back at sea. There were no signs to indicate that the vessel had raised suspicion, even though it had been making the same voyage since 2019.

But they had in fact been spotted. Using Spire's satellite tracking data, experts at Global Fishing Watch had pieced together a history of the vessels’ every move—they’d uncovered suspicious behavior that would have otherwise continued unnoticed.

The Vietnamese vessel transmitted its location during the weeks it spent in Indonesian waters, leaving a trail of digital breadcrumbs.

A success story for Spire and Global Fishing Watch

Monitoring vast oceans needs big data analytics

Today, nearly three million fishing vessels operate across our seas, of which about 60,000— mostly larger vessels—broadcast AIS. With all this traffic, identifying suspicious fishing activity isn’t as simple as following a GPS signal.

The two organizations partnered in 2017, and Global Fishing Watch started consuming Spire’s total AIS feed. When it uploaded the data to its interactive, public map, which visualizes the world’s fishing activity, the chart lit up.

“Having the low-cost, global coverage that you get with the Spire satellite AIS completely transforms our ability to understand what’s going on out there. We also benefit from a dynamic environment where we can interact with the data and collaborate with Spire on how we are going to use it in an open way.”

Charting a course to complete transparency

Transshipment

GFW created models with AIS tracking data to identify transshipment encounters and collect data on a practice that has long avoided oversight.

Spoofing

Spire can provide a complete data history, including the locations of its satellites collecting AIS information, GFW has been able to reveal this masking behavior.

Sound Mapping

Pushing the bounds of possibility even further, GFW is now using AIS to help model the total sound emitted by ships around the world to create a noise map of the ocean.

By channeling this data into advanced data analytics, GFW has been able to build powerful monitoring tools.

There are unbounded opportunities for Maritime Professionals to use AIS data. Let us help you get started.
