Recent Examples on the Web The particular bathymetry of the seafloor here means waves tend to break steeply. 
Tom Vanderbilt, Outside Online, 5 Jan. 2021 During the most recent survey of Lake Powell, USGS scientists produced a topographic map of the lake bed using high-resolution multibeam bathymetry and lidar. Brian Maffly, The Salt Lake Tribune, 22 Mar. 2022 However, mapping bathymetry many fathoms deep with sufficient resolution would require equipment that simply can’t fit on MAS as it is currently configured, said Phaneuf. Smithsonian Magazine, 2 Feb. 2022 Sonar helps scientists map the bathymetry of the ocean in exquisite detail, but current coverage is patchy. Smithsonian Magazine, 2 Feb. 2022 Modern bathymetry now has a range of tools in its cartographic arsenal, from aircrafts using laser imaging technology (LIDAR) that map coastline areas to submersible ROVs, such as those used by MBARI. Ewan Morgan, Smithsonian Magazine, 28 June 2021 This is also the point in which the unique swirling shape in the bathymetry off Pillar Point comes into play. Los Angeles Times, 11 Dec. 2020 When shallow bathymetry slows down a part of a wave, this causes the waves to refract. Sally Warner, The Conversation, 3 Dec. 2020 The shape and depth of the ocean floor is called the bathymetry. Sally Warner, The Conversation, 3 Dec. 2020 See More
