EARTH: Seeing the Seafloor in High Definition

EARTH: Seeing the Seafloor in High Definition
FOR IMMEDIATE RELEASE
6/3/2016
 
Alexandria, VA - As the U.S. celebrates National Oceans Month in June, scientists who study the seafloor are excited because they believe that humans will end this century with a far better view of our seafloor than at any other time in human history. Geoscientists have been mapping land on Earth, and even other planets in our solar system, in high definition for years, but the picture of the ocean floor has remained blurry for the most part. But with advances in engineering, what lies beneath is starting to come into much better focus. 
 
In the June issue of EARTH Magazine, EARTH's Tim Oleson dives into the past, present and future of seafloor mapping, exploring how scientists are working to increase our understanding of the geology, biology and more beneath the waves.  The seafloor has been studied by scientists using echo-sounding technology since the early 20th century; significant advances were made during and after World War II, but these early techniques required a large degree of interpolation and offered only low resolution, limiting the ability of geoscientists to interpret Earth processes. 
 
The development of modern multibeam bathymetry used on oceanographic surveys, satellite technologies, autonomous underwater vehicles and remotely operated vehicles has allowed scientists to study the seafloor at higher resolutions. And the results are helping researchers determine slip rates on submarine faults, gather evidence for explosive volcanism on underwater volcanoes and study sediment movement in submarine canyons.

The June issue of EARTH Magazine brings you exciting stories from around the scientific community. Learn about how icebergs moving about Southern Ocean leave a trail of enhanced phytoplankton activity behind them, and how the 2011 Tohoko Earthquake shook up Japan's iconic Mt. Fuji.

The American Geosciences Institute is a nonprofit federation of geoscientific and professional associations that represents more than 250,000 geologists, geophysicists and other earth scientists. Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in the profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society's use of resources, resiliency to natural hazards, and interaction with the environment.
