The world's ocean floor remains largely uncharted, with only a fraction of its vast expanse mapped to modern standards. This stark reality is highlighted by the comparison to Mars, where the surface has been extensively mapped by robotic orbiters. The Seabed 2030 project has made significant strides, increasing global ocean-floor coverage from 6% to approximately 28.7% since its launch in 2017. However, the task of mapping the entire ocean floor is daunting due to the challenges posed by the physics of deep-ocean mapping, access, and historical research funding. The project's progress is impressive, but the remaining 71% of the ocean floor is disproportionately deep, remote, and difficult to survey. The deadline of 2030 is unlikely to be fully met, but it serves as a catalyst for attention and resource allocation. The importance of seabed mapping extends beyond scientific curiosity, with practical applications in tsunami modeling, undersea cable installation, climate science, and the emerging debate over deep-sea mining. Geopolitical considerations also play a role, as seabed mapping can influence territorial claims and sovereign rights. The future of seabed mapping may rely on advancements in autonomous underwater vehicles and machine learning, which could significantly accelerate coverage gains. Despite the challenges, the Seabed 2030 project has already produced a shift in understanding and describing the ocean floor, and the progress made is a testament to the importance of continued efforts in this field.
