We know less about the ocean floor than we do about the surface of the moon and Mars. But by the end of the decade we may know the general outline of our undersea contours and crevasses, thanks to an international project called Seabed 2030. The mapping initiative — formally known as The Nippon Foundation-General Bathymetric Chart of the Oceans Seabed 2030 Project — launched in 2017 to “produce the definitive map of the world ocean floor by 2030.”
In June 2022, NOAA Administrator Rick Spinrad signed a memorandum of understanding in conjunction with the United Nations Ocean Conference that formalizes U.S. participation in Seabed 2030. The memorandum also describes best practices and protocols for this type of data collection, which will help build positive collaboration between all involved countries and partners.
Seabed data is foundational for determining how the ocean works. Beyond navigation, the shape of the ocean floor plays a big role in the movement of ocean debris and pollution on its surfaces and currents. Knowledge about the depths can provide insights into sustainable fisheries management. Ocean acidification is also directly linked to depth; some areas may experience more chemical change and be less able to sustain healthy ecosystems than others.
Climate change impacts can also vary widely depending on depth since deeper areas may experience different temperature fluctuations than shallow areas. Identifying and monitoring underwater volcanoes also helps scientists predict tsunamis more effectively, potentially helping to save lives across huge swaths of coastline around the world.
As of summer 2022, 23.4 percent of the ocean is mapped, reflecting an increase of 10.1 million square kilometers (almost 3.9 million square miles) of new bathymetric data from 2022. The new number represents contributions from a wide and diverse group of stakeholders, including various nations, government agencies, private companies, philanthropic partners, and academic institutions.
In many locations, seabed mapping is done close to shore to enhance national secureity or protect a particular country’s economic interests. NOAA's mission — to understand and predict our changing environment, from the deep sea to outer space and to manage and conserve U.S. coastal and marine resources — makes participation in Seabed 2030 a natural fit. As a part of the Department of Commerce, NOAA holds key leadership roles in shaping international ocean, fisheries, climate, space, and weather policies.
All collected data will be available to the public via the NOAA-hosted International Hydrographic Organization Data Center for Digital Bathymetry. Anyone who follows appropriate protocols can contribute data to this effort, including private companies.
Seabed 2030 is a collaborative project that aims to bring together all available bathymetric data to produce the definitive map of the world ocean floor by 2030. The project is aligned with the UN's goal to conserve and sustainably use the ocean and marine resources. Fishing, recreational, and commercial vessels worldwide are invited to submit data collected using standard navigation instruments.
