RV Maurice Ewing was a research vessel operated by the Lamont-Doherty Earth Observatory of Columbia University. It was retired in 2005 and replaced by RV Marcus Langseth in 2008. Although a multipurpose vessel, Maurice Ewing's notable capability was to collect multichannel seismic data.
Maurice Ewing was named for William Maurice "Doc" Ewing, geophysicist and first director of Lamont Geological Observatory (now known as Lamont-Doherty Earth Observatory).
The vessel was later renamed several times: - Scan Resolution, Bergan Resolution, the Reflect Resolution, and the NORDIC BAHARI. Still to this day the vessel operates as a multi-streamer seismic research vessel.

William Maurice "Doc" Ewing was an American geophysicist and oceanographer.
J. Lamar (Joe) Worzel was an American geophysicist known for his important contributions to underwater acoustics, underwater photography, and gravity measurements at sea.
Frank Press was an American geophysicist.He was an advisor to four U.S. presidents, and later served two consecutive terms as president of the U.S. National Academy of Sciences (1981–1993). He was the author of 160 scientific papers and co-author of the textbooks Earth and Understanding Earth.
Wallace "Wally" Smith Broecker was an American geochemist. He was the Newberry Professor in the Department of Earth and Environmental Sciences at Columbia University, a scientist at Columbia's Lamont-Doherty Earth Observatory and a sustainability fellow at Arizona State University. He developed the idea of a global "conveyor belt" linking the circulation of the global ocean and made major contributions to the science of the carbon cycle and the use of chemical tracers and isotope dating in oceanography. Broecker popularized the term "global warming". He received the Crafoord Prize and the Vetlesen Prize.
Marie Tharp was an American geologist and oceanographic cartographer who, in partnership with Bruce Heezen, created the first scientific map of the Atlantic Ocean floor. Tharp's work revealed the detailed topography and multi-dimensional geographical landscape of the ocean bottom. Her work also revealed the presence of a continuous rift valley along the axis of the Mid-Atlantic Ridge, causing a paradigm shift in earth science that led to acceptance of the theories of plate tectonics and continental drift.
The Lamont–Doherty Earth Observatory (LDEO) is a research unit of Columbia University located on a 157-acre (64 ha) campus in Palisades, N.Y., 18 miles (29 km) north of Manhattan on the Hudson River.
The Earth Institute was established at Columbia University in 1995. The research institute's stated mission is to address complex issues facing the planet and its inhabitants, with a focus on sustainable development. With an interdisciplinary approach this includes research in climate change, geology, global health, economics, management, agriculture, ecosystems, urbanization, energy, hazards, and water. The Earth Institute's activities are guided by the idea that science and technological tools that already exist could be applied to greatly improve conditions for the world's poor, while preserving the natural systems that support life on Earth.
R/V Marcus Langseth is a research vessel owned by the National Science Foundation and operated by the Lamont-Doherty Earth Observatory (LDEO) of Columbia University as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. The Marcus G. Langseth was dedicated on December 4 2007, came into service in early 2008, replacing the R/V Maurice Ewing. Langseth is intended primarily to collect multichannel seismic data, including 3-D surveys. The ship was purchased from the geophysical survey company WesternGeco in 2004, having previously been named M/V Western Legend.
A multibeam echosounder is a type of sonar that is used to map the seabed. Like other sonar systems, multibeam systems emit sound waves in a fan shape beneath a ship's hull. The amount of time it takes for the sound waves to bounce off the seabed and return to a receiver is used to determine water depth. Unlike other sonars, multibeam systems use beamforming to extract directional information from the returning soundwaves, producing a swath of depth readings from a single ping.
Walter Clarkson Pitman III is an American geophysicist and a professor emeritus at Columbia University. His measurements of magnetic anomalies on the ocean floor supported the Morley–Vine–Matthews hypothesis explaining seafloor spreading. With William Ryan, he developed the Black Sea deluge theory. Among his major awards are the Alexander Agassiz Medal and the Vetlesen Prize.
Graham Michael "Mike" Purdy is a British geophysicist and oceanographer who specializes in marine seismology. He is the current Executive Vice President for Research at Columbia University. Previously, he was the Director of Columbia's Lamont-Doherty Earth Observatory (LDEO).
Dallas Abbott is a research scientist at the Lamont-Doherty Earth Observatory of Columbia University and is part of the Holocene Impact Working Group. The primary focus of her present research is on submarine impact craters and their contribution to climate change and megatsunamis. She also has presented research regarding a large impact crater in the Gulf of Maine.
Robert D. Conrad (T-AGOR-3) was a Robert D. Conrad-class oceanographic research ship that operated from 1962 to 1989. The ship, while Navy owned, was operated as the R/V Robert D. Conrad by the Lamont–Doherty Earth Observatory of Columbia University from delivery to inactivation. The ship provided valuable ocean-bottom, particularly seismic profile, information and underwater test data to the U.S. Navy and other U.S. agencies.
Paul G. Richards is an English-born, American seismologist who has made fundamental contributions to the theory of seismic wave link propagation and in methods to understand how the recorded shapes of seismic waves are affected by processes of diffraction, attenuation and scattering. He is the Mellon Professor of the Natural Sciences at Lamont-Doherty Earth Observatory of Columbia University.
The research vessel Vema was a three-masted schooner of the Lamont Geological Observatory, a research unit of Columbia University. The 202 ft (62 m). waterline vessel, with her almost indestructible Swedish wrought iron hull, became renowned as one of the world’s most productive oceanographic research vessels. The ship had been first sailed for pleasure under the name Hussar, and after her career as a research vessel entered a new career as the cruising yacht Mandalay.
The Vetlesen Prize is a prize in geology awarded jointly by Columbia University's Lamont-Doherty Earth Observatory and the G. Unger Vetlesen Foundation. The prize is generally regarded as the highest distinction in geologic studies, and the "Nobel Prize for geology".
Georg Unger Vetlesen was a Norwegian-American shipbuilder and philanthropist.
The Maurice Ewing Medal is awarded by the American Geophysical Union for "significant original contributions to the understanding of physical, geophysical, and geological processes in the ocean; to those who advance oceanographic engineering, technology, and instrumentation; and to those who perform outstanding service to the marine sciences". The award was instituted in 1974 and is jointly sponsored by the United States Navy. The award is named in honor of Maurice Ewing.
Robin Elizabeth Bell is a professor at Columbia University's Lamont-Doherty Earth Observatory. She was influential in co-ordinating the 2007 International Polar Year and was the first woman to chair the National Academy of Sciences Polar Research Board. She has made numerous important discoveries with regard to subglacial lakes and ice sheet dynamics, and has a ridge, called Bell Buttress, in Antarctica named after her.
Patience Anne Cowie is a Professor of Earth System Dynamics at the University of Bergen. Her research has considered fault propagation and rift basins. She was awarded the 2016 Geological Society of London Coke medal.
