Maurice Ewing

Maurice Ewing was a scientist. He studied the ocean and the Earth.

He looked at the deep sea floor. He also found a way for sound to travel in water. This helped him find lost ships. He led many trips on the sea. He even studied how the moon moves. Many awards were given to him. A big ship was named after him too. His work helps us learn about our world.

Maurice Ewing was a famous scientist. He studied the Earth and the ocean. People often called him "Doc." He was a geophysicist. This means he studied how the Earth works using physics.

Ewing did many important things. He found the SOFAR channel. This is a way sound travels deep in the ocean. He also used cameras to see the deep sea. This helped the government find lost ships. Ewing led over 50 trips on the ocean. He studied how earthquakes move and how the Earth's core flows. He even worked on how the moon shakes.

He started a place called the Lamont Geological Observatory. Now it is called the Lamont–Doherty Earth Observatory. He wrote more than 340 science papers. He won many big awards. One was the National Medal of Science. People even named a part of the moon after him. They called it Dorsa Ewing. A large research ship was also named the R/V Maurice Ewing to honor him.

Maurice Ewing was a famous American scientist who studied our planet. He was a geophysicist and an oceanographer. A geophysicist is someone who uses physics to understand the Earth. An oceanographer studies the deep, salty waters of our oceans. Many people called him "Doc" because of his deep knowledge. He wanted to know how the Earth works from the surface to the core. His work helped us understand many things about our world.

Ewing found many ways to see things that are hidden. He discovered the SOFAR channel, which is a way sound travels through the ocean. He also used deep water photography to look at the sea floor. This helped the government find ships that were lost underwater. He studied how earthquakes move across the surface of the Earth. He also looked at how the Earth's core flows like a liquid. He even studied how the moon shakes during certain events.

Ewing grew up in a large farm family in Lockney, Texas. He was born on May 12, 1906. He went to Rice University on a scholarship. He earned his BA in 1926 and his PhD in 1931. Later, he joined the faculty at Lehigh University in 1930. In 1947, he became a professor of geology at Columbia University. He was the founder of the Lamont Geological Observatory in 1949. This place is now called the Lamont–Doherty Earth Observatory.

Ewing was a very busy and successful researcher. He led more than 50 expeditions out on the ocean. He published over 340 scientific papers during his life. He won many important honors, like the National Medal of Science in 1973. He was also elected to the National Academy of Sciences in 1948. He even received the Gold Medal of the Royal Astronomical Society in 1964. He died in Galveston, Texas, in May of 1974.

Today, we still remember his name in many places. A large research ship was named the R/V Maurice Ewing. Scientists even named a ridge on the moon Dorsa Ewing. A building at the University of Texas is called Maurice Ewing Hall. His work on plate tectonics helped us understand how continents move. He also helped start Project Mogul to detect nuclear tests. His life shows how curious people can learn the secrets of the Earth and space.

Maurice Ewing was a pioneering American scientist who studied the mysteries of our planet. He was a geophysicist and an oceanographer. A geophysicist uses the laws of physics to study the Earth's structure and movement. An oceanographer studies the physical and biological aspects of the ocean. Known by his colleagues as "Doc," Ewing dedicated his life to understanding the Earth from its surface to its core. His research helped change how we understand the very foundation of our world.

Ewing developed many ways to observe things that are hidden deep underwater. He discovered the SOFAR channel, which is a layer in the ocean where sound travels very effectively. He also invented the "sofar bomb" to help study these underwater sounds. To see the ocean floor, he used deep water photography. This work was partly a hobby and partly used by the government to find ships lost to U-boats. He also studied seismic reflection and refraction in ocean basins. These methods involve using sound waves to map what lies beneath the sea floor.

His research covered many different scientific areas. He studied the theory and observation of earthquake surface waves to understand how the ground moves. He also investigated the fluidity of the Earth's core to see how it behaves. Ewing looked at the generation and propagation of microseisms, which are tiny earth tremors. He conducted marine gravity surveys and studied bathymetry, which is the measurement of ocean depth. He even examined the natural radioactivity found in ocean waters and sediments. His work on abyssal plains and submarine canyons helped map the deepest parts of the sea.

Ewing's academic journey began in Lockney, Texas. He was the eldest surviving child in a large farm family. He attended Rice University on a scholarship, earning his BA in 1926. He stayed at Rice for graduate studies, receiving his MA in 1927 and his PhD in 1931. He taught at the Rice Institute while finishing his doctorate. In 1930, he joined the faculty at Lehigh University. He was instrumental in starting a geophysics program there. In 1947, he moved to Columbia University as a professor of geology. By 1959, he was named the Higgins Professor of Geology at Columbia.

In 1949, Ewing founded the Lamont Geological Observatory. This center is now known as the Lamont–Doherty Earth Observatory (LDEO) in Palisades, New York. He worked there with many famous scientists. These included J. Lamar Worzel, Frank Press, Jack Nafe, and Jack Oliver. He also collaborated with oceanographic cartographers Marie Tharp and Bruce Heezen. Ewing was a very active researcher throughout his career. He led more than 50 oceanic expeditions and published over 340 scientific papers. He also served as president of the American Geophysical Union and the Seismological Society of America.

Ewing received many prestigious honors for his contributions to science. In 1973, he was awarded the National Medal of Science. He was elected to the National Academy of Sciences in 1948. He also became a Foreign Member of the Royal Society in 1972. Other awards included the Penrose Medal, which he received posthumously in 1974. He won the Gold Medal of the Royal Astronomical Society in 1964. His work was so significant that several awards were named after him. These include the Maurice Ewing Medals from the Society of Exploration Geophysicists and the American Geophysical Union.

His influence can still be seen in science today. A research vessel, the R/V Maurice Ewing, was named in his honor. On the moon, a wrinkle ridge named Dorsa Ewing bears his name. At the University of Texas Medical Branch, a building called Maurice Ewing Hall stands in his memory. His fundamental work helped support the theory of plate tectonics. This theory explains how the Earth's outer shell is divided into large plates. He also helped with Project Mogul, an early program to detect Soviet nuclear weapons tests. Even in space, his impact remains.

In 1972, he was seen viewing seismometer readings from the Apollo 17 Saturn S-IVB stage impact on the moon.
