Seafloor Mapping - NOAA Ocean Exploration
2022年7月20日 — NOAA Ocean Exploration has been mapping the seafloor of the Blake Plateau off the Southeast United States aboard NOAA Ship Okeanos Explorer (left) since 2011. As a result of this mapping, NOAA Ocean Exploration and partner scientists discovered mounds of extensive, dense populations of the deep-sea, reef-building coral Lophelia pertusa (middle ...
Sea Floor Mapping - NOAA Ocean Exploration
Sea Floor Mapping. The first primitive maps of the sea floor came from “soundings” which involved lowering weighted lines into the water and noting when the tension on the line slackened. The depth was then measured by the amount of line that had payed out.
Why we map the ocean floor - ArcGIS StoryMaps
Collecting data about the ocean floor enables us to anticipate natural disasters like earthquakes, volcanoes, and tsunamis, and mitigate their effects. This information can improve our understanding of undersea habitats and equip us with the tools to make informed decisions about marine conservation.
Why Map the Seafloor? To Understand What’s There - NOAA Ocean …
Seafloor mapping is the first step in exploring our ocean. Once scientists or resource managers have identified an area they would like to know more about, ships equipped with technology such as multibeam sonar can collect data used to generate high-resolution bathymetric maps of that part of the seafloor.
Seafloor Features and Mapping the Seafloor | manoa.hawaii.edu ...
To map the seafloor, research vessels cross the ocean making sonar profiles along carefully navigated, parallel courses called transect lines. After many profiles are made, they can be assembled to create complex maps or three-dimensional models of the seafloor by filling the spaces between the profiles using computer models, or modeling ...

2022年8月1日 — Investigators at the National Oceanic and Atmospheric Administration have finished mapping the “million mounds” deep-sea province. Thousands of coral mounds, each 30 to 300 feet high, blanket...
Mapping the Gaps in Our Ocean Knowledge with Seabed 2030
2021年6月29日 — The mapping initiative, called Seabed 2030, 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 that formalizes U.S. participation in the project.
Can Scientists Map the Entire Seafloor by 2030? | Smithsonian
2021年6月28日 — Seafloor mapping is expensive and technologically intensive, but it holds value to a wide range of fields. Scientists can use information on the shape of the seafloor to understand a myriad of...
Ocean Month: Discovering our ocean through monitoring, …
2024年6月7日 — Through exploration, NOAA is constantly learning more about the ocean’s biological, geological, and maritime heritage aspects. Exploration leads to discovery, but before one can truly explore, one must map the seafloor. As of 2023, only 25% of the global seafloor had been mapped with modern high-resolution technology.
