Harry Hammond Hess

Harry Hammond Hess (May 24, 1906 – August 25, 1969) was a geologist and a United States Navy officer in World War II.

Considered one of the "founding fathers" of the unifying theory of plate tectonics, Rear Admiral Harry Hammond Hess was born on May 24, 1906, in New York City. He is best known for his theories on sea floor spreading, specifically work on relationships between island arcs, seafloor gravity anomalies, and serpentinized peridotite, suggesting that the convection of the Earth's mantle was the driving force behind this process. This work provided a conceptual base for the development of the theory of plate tectonics.

Teaching career

Harry Hess taught for one year (1932–1933) at Rutgers University in New Jersey and spent a year as a research associate at the Geophysical Laboratory of Washington, D. C., before joining the faculty of Princeton University in 1934. Hess remained at Princeton for the rest of his career and served as Geology Department Chairman from 1950 to 1966. He was a visiting professor at the University of Cape Town, South Africa (1949–1950), and the University of Cambridge, England (1965).

The Navy-Princeton gravity expedition to the West Indies in 1932

Hess accompanied Dr. Felix Vening Meinesz of Utrecht University on board the US Navy submarine USS S-48 to assist with the second U.S. expedition to obtain gravity measurements at sea. The expedition used a gravimeter, or gravity meter, designed by Meinesz.[4] The submarine traveled a route from Guantanamo, Cuba, to Key West, Florida, and return to Guantanamo through the Bahamas and Turks and Caicos region from 5 February through 25 March 1932. The description of operations and results of the expedition were published by the U.S. Navy Hydrographic Office in The Navy-Princeton gravity expedition to the West Indies in 1932.[5]

Military and war career

Hess joined the United States Navy during World War II, becoming captain of the USS Cape Johnson, an attack transport ship equipped with a new technology: sonar. This command would later prove to be key in Hess's development of his theory of sea floor spreading. Hess carefully tracked his travel routes to Pacific Ocean landings on the Marianas, Philippines, and Iwo Jima, continuously using his ship's echo sounder. This unplanned wartime scientific surveying enabled Hess to collect ocean floor profiles across the North Pacific Ocean, resulting in the discovery of flat-topped submarine volcanoes, which he termed guyots, after the nineteenth century geographer Arnold Henry Guyot. After the war, he remained in the Naval Reserve, rising to the rank of rear admiral.

Scientific discoveries

In 1960, Hess made his single most important contribution, which is regarded as part of the major advance in geologic science of the 20th century. In a widely circulated report to the Office of Naval Research, he advanced the theory, now generally accepted, that the Earth's crust moved laterally away from long, volcanically active oceanic ridges. He only understood his ocean floor profiles across the North Pacific Ocean after Marie Tharp and Bruce Heezen (1953, Lamont Group) discovered the Great Global Rift, running along the Mid-Atlantic Ridge.[6][7] Seafloor spreading, as the process was later named, helped establish Alfred Wegener's earlier (but generally dismissed at the time) concept of continental drift as scientifically respectable. This triggered a revolution in the earth sciences.[8] Hess's report was formally published in his History of Ocean Basins (1962),[9] which for a time was the single most referenced work in solid-earth geophysics. Hess was also involved in many other scientific endeavours, including the Mohole project (1957–1966), an investigation onto the feasibility and techniques of deep sea drilling.

Accolades and affiliations

Hess was president of The Geological Society of America in 1963 and received their Penrose Medal in 1966.[10]

Death

Hess died from a heart attack in Woods Hole, Massachusetts, on August 25, 1969, while chairing a meeting of the Space Science Board of the National Academy of Sciences. He was buried in the Arlington National Cemetery and was posthumously awarded the National Aeronautics and Space Administration's Distinguished Public Service Award.

The Harry H. Hess Medal

The American Geophysical Union established the Harry H. Hess medal in his memory in 1984 to "honor outstanding achievements in research of the constitution and evolution of Earth and sister planets."[11][12][13]

Geology of Antigua and Barbuda

The geology of Antigua and Barbuda is part of the Lesser Antilles volcanic island arc. Both islands are the above water limestone "caps" of now inactive volcanoes. The two islands are the surface features of the undersea Barbuda Bank and have karst limestone landscapes.

Barbuda is primarily flat and formed from coral reefs. The Middle Miocene Highlands Formation has limestones which are the oldest rocks on the island, rising 120 feet above sea level. The Beazer Formation and the Codrington Formation are both from the Pleistocene and comprise reef and lagoon related rocks.The geologic record of Antigua indicates a transition from island arc volcanism to limestone deposition in the Late Oligocene. Hence the island is characterized by a Basal Volcanic Suite (BVS) on the mountainous southwest, a Central Plain Group (CPG) extending from St. Johns to the southeast, and the Antigua Formation on the northeast portion of the island in the direction of regional dip. The CPG consists of siliciclastic and limestone, marine and non-marine sedimentary rocks, containing petrified wood and gastropods within chert. The Antigua Formation includes benthic foraminifers and molluscs, scleractinian corals, echinoids, crabs, bryozoans, crinoid columns and sponges. The limestone Devil's Bridge, is an example of this formation.On Antigua, the south of the island is mainly calc-alkaline volcanic rock such as dacite and quartz basalt or andesite, along with limestone lenses, agglomerate and tuff formed during the Oligocene. Generally andesite dominated volcanism across the island gave way to limestone and chert formation.Between 200 and 500 CE, native peoples on Antigua were active in lapidary, working local diorite, shells and carnelian as well as imported nephrite, amethyst, turquoise and serpentinite.

Guyot

In marine geology, a guyot (pronounced ), also known as a tablemount, is an isolated underwater volcanic mountain (seamount) with a flat top more than 200 m (660 ft) below the surface of the sea. The diameters of these flat summits can exceed 10 km (6.2 mi). Guyots are most commonly found in the Pacific Ocean, but they have been identified in all the oceans except the Arctic Ocean.

History of geophysics

The historical development of geophysics has been motivated by two factors. One of these is the research curiosity of humankind related to planet Earth and its several components, its events and its problems. The second is economical usage of Earth's resources (ore deposits, petroleum, water resources, etc.) and Earth-related hazards such as earthquakes, volcanoes, tsunamis, tides, and floods.

Goldsmith, along with colleague Fritz Laves, first defined the crystallographic polymorphism of alkali feldspar (Newton, 1989). Goldsmith also experimented on the temperature dependence of the solid solution between calcite and dolomite (Newton, 1989). Goldsmith’s research also led him to experiment with the determination of the stability of intermediate structural states of albite (Newton, 1989). For his outstanding contributions to the study of mineralogy and geochemistry, Goldsmith was awarded the prestigious Roebling Medal by the Mineralogical Society of America in 1988 (Newton, 1989). The mineral julgoldite was named for him.

Robert S. Dietz

Robert Sinclair Dietz (September 14, 1914 – May 19, 1995) was a scientist with the US Coast and Geodetic Survey. Dietz was a marine geologist, geophysicist and oceanographer who conducted pioneering research along with Harry Hammond Hess concerning seafloor spreading, published as early as 1960–1961. While at the Scripps Institution of Oceanography he observed the nature of the Emperor chain of seamounts that extended from the northwest end of the Hawaiian Island–Midway chain and speculated over lunch with Robert Fisher in 1953 that something must be carrying these old volcanic mountains northward like a conveyor belt.In later work he became interested in meteorite impacts, was the first to recognize the Sudbury Basin as an ancient impact event, and discovered a number of other impact craters. He championed the use of shatter cones as evidence for ancient impact structures. He received the Walter H. Bucher Medal from the American Geophysical Union in 1971, the Barringer Medal from the Meteoritical Society in 1985 and the Penrose Medal from the Geological Society of America in 1988.

Dietz was an outspoken critic of creationism, and was the faculty advisor of two student groups at Arizona State University in 1985, Americans Promoting Evolution Science (APES) and the Phoenix Skeptics. Dietz spoke on evolution and creationism at meetings of these groups, and debated creationist Walter Brown and Christian apologist William Lane Craig at Arizona State University.

Samuel Calvin (geologist)

Samuel Calvin (February 2, 1840 – April 17, 1911) was Iowa's first systematic geologist, helping to make the first bedrock and landform maps of Iowa, as well as leading geological research throughout the state. He was born in Scotland, attended Lenox College (now defunct) in Hopkinton, Iowa, where he later taught. One of his collaborators was Thomas Huston Macbride, the notable Iowa naturalist. Calvin became a University of Iowa professor in 1873 and the Iowa State Geologist in 1892, and led the Iowa Geological Survey from 1892 until his death. Calvin documented the Devonian and Aftonian beds of Iowa, and was an expert on Pleistocene fauna. He was a founder of the American Geologist journal. Calvin Hall at the University of Iowa is named for him. His photographic collection of Iowa scenes is an important collection for historians and geologists. Calvin was president of the Geological Society of America in 1908.
