activity from space

Before satellite technology, destructive environmental actions often remained hidden from view. We use the latest technology to make stunning satellite imagery and other robust remote sensing data accessible to anyone for free, to hold polluters and others accountable for harmful activities that would otherwise remain hidden from view.

Dark Vessels Q&A: Bringing Transparency to Hidden Ocean Pollution

June 6, 2025

SkyTruth recently launched a new feature in Cerulean that identifies oil pollution from "dark vessels" -- ships that don't broadcast their location via Automatic Identification System (AIS).

This Q&A with SkyTruth's Principal Product Manager, Kris Moreau, and Machine Learning Engineer, Jona Raphael, explores how this technology works, what they've discovered so far, and what it means for ocean transparency.

Tanker Falsifies and Disables AIS Tracking To Hide Entries Into Russian Ports While Leaving a Trail of Pollution in European Waters

February 18, 2025

The Liberian-flagged tanker NEW SUNRISE is currently broadcasting a false location in the Persian Gulf after leaving a trail of oily waste and unanswered questions regarding its activities in European waters over the past few months.

Analysis fueled by SkyTruth and Global Fishing Watch reveals that the operators of the NEW SUNRISE petrochemical tanker falsified their Automatic Identification System (AIS) position broadcast between November 14 and November 25, 2024, as well as between February 4, 2025 and the date of this publication (February 18, 2025).

Leveling up Cerulean’s Ability To Reveal Stationary Polluters

January 16, 2025

Recent advancements in Cerulean's infrastructure association algorithms are bringing us closer than ever to accurately identifying stationary polluters at sea.

A primary goal of SkyTruth’s global oil pollution detection tool, Cerulean, is to automatically attribute oil slicks to potential polluters.
