The UK Maritime Management Organisation (MMO) has published an official statement informing the fishing industry and other maritime users of recorded boulder positions in the southern North Sea. According to the announcement, the rocks were dumped by activists of the environmental organisation Greenpeace. The MMO recommends all vessels engaged in fishing activities or otherwise using the specified waters to take into account the reported coordinates for maritime safety and preservation of fishing equipment. Such underwater obstacles may pose a risk to bottom trawls and other fishing gear, as well as create potential hazards during navigation in shallow waters. Greenpeace has previously conducted operations placing boulders on the seabed in various parts of the North Sea as part of a campaign to protect designated marine areas from bottom trawling. Activists claim that such measures physically impede the work of heavy fishing vessels in environmentally sensitive zones, thus contributing to the restoration of marine ecosystems. The MMO, as the regulatory body responsible for managing UK maritime activities, monitors such incidents and informs interested parties to minimise risks. The agency did not specify whether any measures are planned regarding the Greenpeace action itself, focusing exclusively on maritime safety and fishing operations in the affected area.
