A global initiative by the Nippon Foundation-GEBCO in relentless pursuit of achieving a complete map of the ocean floor by 2030 Endorsed by the UN Ocean Decade
Looking ahead to 2026, it’s clear that #AI will be a central thread of discussion in ocean science.

So here's a primer on how it is already beginning to transform how we acquire, interpret, and apply bathymetric data > making surveys faster and more cost-effective, and accelerating impact.

🗂️ Working towards a complete map of the seabed doesn’t mean starting from scratch.

In fact, a large volume of #bathymetric data already exists - but much of it remains inaccessible or not yet widely discoverable.

Why? A few common factors play a role:
January 23, 2026 at 1:43 PM
🌊 Did you know that #seafloor maps play a critical role in tsunami prediction?

Bathymetry plays a foundational role in tsunami simulations, influencing wave propagation and arrival times that inform evacuation planning and early warning efforts.

🤔 Ever heard of “isobaths”?

If you’ve looked at a bathymetric chart, you’ve seen them - even if you didn’t know the name.

⭕️ Isobaths are contour lines that connect points of equal depth on the seafloor, much like topographic contours on land maps connect points of equal elevation.

👀 Can you identify this #underwater feature?

HINT: It's the longest mountain range on Earth.

Yet you’ve probably never seen it - because most of it lies beneath around 2,500 metres of ocean water.

The ocean floor isn't static. From tectonic shifts to storm-driven sediment flows, it’s always changing.

⏳ In some places, sudden events can shift the seafloor by metres in moments - while in others, change happens millimetre by millimetre over millennia.

🌐 Much of the global #internet relies on infrastructure that runs across the deep #ocean - and understanding that terrain is essential to keeping it connected.

✨Happy New Year from Seabed 2030!

As 2026 begins, our work to support a complete and openly available map of the #oceanfloor continues.

From climate research and ocean stewardship to marine planning and hazard assessment, access to accurate seabed information is becoming ever more important.

Mapping the #seafloor is a collective effort, and everyone can play a role in advancing this global mission.

Whether you work in:

🏢 Government 
📈 Industry
🔍 Research
🌐 Non-profit
💳 Philanthropy

...or are an individual with a passion for the ocean, there is a place for you in the community.

🙏 As the year draws to a close, we’d like to take a moment to thank everyone across the ocean mapping community.

From technical partners and academic institutions to intergovernmental organisations and citizen scientists, the mission to map the ocean floor is a truly collective effort.

Despite major technological advances and international efforts, large areas of the world’s seabed remain poorly mapped - and access to detailed seabed information is uneven.

🤔 Did you know that many nations do not have their own hydrographic office? This is where global ocean-mapping efforts play an important supporting role.

👀 The #ocean’s surface reveals only a fraction of the world beneath.

What lies below is a complex landscape of ridges, plains, valleys, and volcanic features shaped by Earth’s geological and ecological processes.

🗺️ Most people presume the ocean is already mapped.

📍Even checking Google Maps can give that impression: the ocean appears covered in smooth blue shapes that look like detailed topographic features.

Yet most of these are not based on direct measurements.

🤔 Looking for the latest version of the #GEBCO map?

The 2025 GEBCO bathymetric grid is available to download here:

The grid shows areas of the seafloor considered mapped - now covering 27.3% of the world's ocean floor.

Our mission is not just to inspire a complete map of the #oceanfloor - it’s to help ensure that knowledge of the ocean is accessible to all.

🤖 Robots. They’re one of the biggest game-changers in ocean mapping.

Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) are expanding our ability to map and study the #seafloor with greater reach and precision than ever before.

🌊 Did you know that many countries have more territory underwater than above it?

🇬🇧 United Kingdom: around 28x more ocean than land
🇫🇷 France: around 21x more ocean than land
🇳🇿 New Zealand: around 15x more ocean than land
🇯🇵 Japan: around 12x more ocean than land
