130 Marine Pollution Incidents Found During Surveillance Flights - Germany Tracks Over 100 Marine Pollution Cases in 2025 Using Aerial Surveillance

German authorities recorded over 100 cases of marine pollution in the North and Baltic Seas during 2025. The incidents included oil spills and unidentified substances, with most pollution appearing in small, hard-to-clean quantities. Aerial surveillance has played a key role in tracking these violations for decades.

Two Dornier Do 228 aircraft, fitted with radar, infrared, and ultraviolet sensors, carried out the monitoring flights. Their equipment helps detect contamination and pinpoint possible offenders. This system has been in operation for 40 years.

Of the 130 reported cases, 109 occurred in the North Sea and 21 in the Baltic Sea. Investigators identified potential culprits in 48 instances, achieving a clearance rate of around 37%. However, the vast majority of oil spills were too minor for effective cleanup efforts.

No official figures were released regarding pollution cases in the Dutch, Danish, or Swedish waters of the same regions. The focus remained on German territorial waters, where aerial patrols continue to monitor and document violations.

The 2025 findings highlight ongoing challenges in tackling small-scale marine pollution. While surveillance technology helps track and identify offenders, many spills remain too dispersed for practical removal. Authorities will keep relying on aerial monitoring to address contamination in these critical waterways.
