Issuer: Greenwater Marine Sciences Offshore Inc.

Supplying small and efficiently crewed ships that are suitable for coastal and near-shore research projects.

Ocean science not getting done

The demand for research activities at sea currently outstrips the availability of research vessels, hampering efforts to better understand ocean ecosystems and processes. Demand is expected to grow in the years ahead in response to increasing needs for ocean science to address climate change, declining ocean health, and other societal challenges. The current fleet capacity, mainly supplied by the U.S. federal government and universities, consists primarily of large research vessels with high operating costs. Smaller, affordable, appropriately outfitted ships are difficult to hire.

GMSO’s mission

Greenwater Marine Sciences Offshore Inc. will provide small, professionally crewed research vessels that are suitable for coastal and near-shore research projects to satisfy this unmet demand. Embracing its core values (operational expertise, adaptability, efficiency, and a passion for the oceans), GMSO will provide a public benefit as a B-Corporation by facilitating science at sea with an affordable pricing structure that expands ocean research opportunities to scientists and explorers who would otherwise be unable to find or afford such vessels.
