Seafloor Mapping in 60 Seconds | Nautilus Live

How exactly do we map the seafloor? Onboard E/V Nautilus, our Corps of Exploration uses the Kongsberg EM302 multibeam echosounder to create detailed seafloor maps. By generating sound beams and collecting returning data, this technology allows us to piece together the topography of the deep sea. Seafloor mapping began over a century ago, yet less than 25 percent of the world’s ocean has been charted at high resolutions. Our seafloor maps contribute to the Seabed 2030 initiative, an international collaborative project to combine all bathymetric data to create a comprehensive map of the ocean floor.

Having 3D maps of the seafloor also leads our ocean exploration goals. When exploring little-known ocean regions, we often need to create our own maps to plan efficient and safe operations. Whether focused on a canyon, seamount, or shipwreck, creating a map allows us to identify potential targets, cutting down exploration time and boosting our mission efficiency. Before ROVs are deployed, our team must first map the area to understand the region's characteristics and identify potential benthic habitats, seeps, and other environments and resources worthy of exploration.

So close yet, seemingly, so far! Keep up your excellent pioneering work!

Does the echo location disturb the animals in the sea?

And does this sonar process compel whales and sharks to beach themselves trying to escape the noise?

Any such equipment for river bed measurement stitched to either banks and above water features. Project location south east asia.

How do you work around "false sea beds" like lantern fish?

is it dangerous to marine life right under the ship?

Awesome video! Makes me wonder if you could use a pair of underwater drones like the Chasing M2 Pro to get a even more detailed three dimensional representation?

Globe propaganda. All angle measurements require 2 straight lines. This is done agains a horizontal plane. FLAT
