How do you collect bathymetry data?

Multi-beam surveying: A multibeam echo sounder attached to a boat sends out a wide array of beams across a "swath" of the waterbody floor. As the beams are bounced back from the waterbody floor, the data is collected and processed.

Where can I get bathymetry data?

NOAA (National Oceanic and Atmospheric Administration) is the primary source of bathymetric data for the world's oceans. See their Bathymetry website for information.

What are the sources of bathymetric data?

Primary sources of bathymetry in NBS program compilations include NOAA and U.S. Army Corps of Engineers hydrographic and topographic-bathymetric LiDAR data.

How to get bathymetry data?

NOAA (National Oceanic and Atmospheric Administration) is the primary source of bathymetric data for the world's oceans.

What is Multibeam data?

Multibeam collects two types of data: seafloor depth and backscatter. The seafloor depth, or bathymetry, is computed by measuring the time it takes for the sound to leave the array, hit the seafloor, and return to the array.

Does Google Earth show bathymetry?

We have files called GeoTIFFs available for download on several of our data product pages. When viewed in Google Earth, you will be able to see highly detailed features on the seafloor like in the image below.
