Gigablue has unveiled a next-generation remotely operated vehicle (ROV) designed to advance the company’s measurement, monitoring, reporting, and verification (MMRV) framework for marine carbon removal.
Built in collaboration with Astral-Subsea, the new ROV supports our approach to Microalgae Carbon Fixation and Sinking (MCFS) by enabling precise, in-situ tracking and sampling of engineered substrates as they sink to the deep ocean. With enhanced imaging, particle-specific sampling, and an extended depth range of 500 meters, the system delivers the kind of reliable, ground-truth data required to validate durable carbon sequestration.
The ROV is compact, efficient, and deployable from small vessels, reducing emissions and operational costs while expanding the scope of monitoring.
This milestone builds on Gigablue’s earlier deployments and strengthens partnerships with key collaborators including Seaworks and Kernohan Engineering. Together, these efforts reinforce Gigablue’s commitment to scientifically grounded, transparent, and scalable carbon removal. Preliminary trials of the new ROV have already taken place in the Gulf of Aqaba, with further open-ocean missions planned in New Zealand’s Exclusive Economic Zone.
By combining innovation in marine technologies, like robotics, with rigorous MMRV protocols, we continue to demonstrate how ocean-based solutions can deliver durable carbon storage safely, effectively, and affordably at climate-relevant scale.
