Cesare Emiliani

from Wikipedia, the free encyclopedia

Cesare Emiliani (born December 8, 1922 in Bologna , † July 20, 1995 in Palm Beach Gardens , Florida ) was an Italian-American scientist. He is one of the most famous geologists and micropalaeontologists of the 20th century.

Life

Cesare Emiliani was born in Bologna . His parents were Luigi and Maria (Manfredidi) Emiliani. He studied geology at the University of Bologna in post-war Italy and obtained his doctorate in geology (micropalaeontology) in Bologna in 1945. After graduating, he worked from 1946 to 1948 as a micropalaeontologist at the Società Idrocarburi Nazionali in Florence . In 1948 he accepted the Rollin D. Salisbury Fellowship of the Department of Geology at the University of Chicago , where he received his second Ph.D. in geology (isotopic paleoclimatology) in 1950.acquired. From 1950 to 1956 he was a research fellow in Harold Urey's geochemistry laboratory at the Enrico Fermi Institute at the University of Chicago.

In 1957, Emiliani was working on foraminifera , particularly interested in the major climate change events that were known to have occurred during the Pleistocene . He was sure that valuable clues could be found in the tiny bowls found in the ubiquitous mud on the ocean floor. For this reason, he looked for a job where ships and trained personnel were available who could help him with the recovery of drill cores from deep-sea sediments for his studies. A conversation with Walton Smith convinced Cesare that the Institute of Marine Science at the University of Miami - later the Rosenstiel School of Marine and Atmospheric Sciences - was the right place for his research; then he moved there that same year. In 1967 he was appointed chairman of the department of geology and geophysics of the institute. It was around this time that he established the geosciences department on the main University of Miami campus and remained its chairman until he left.

In 1995 he died in Palm Beach Gardens , Florida .

Emiliani is considered to be the founder of palaeoceanography and developed the oxygen isotope level , which is still widely used today, despite modifications.

He established the knowledge in science that the ice ages of the last 500,000 years are linked to the Milanković cycles and thus supported Milankovitch's hypothesis, which revolutionized the history of the oceans and glaciations. He also advocated the US National Science Foundation's "LOCO Project" (LOCO = Long Cores) . The project was a success and provided strong clues to reconstruct the history of the oceans and also served as a test of the hypotheses of ocean floor spreading and plate tectonics .

In his later years he devoted a calendar reform much of his time, on the concept of the Holocene calendar was based around the BC-AD chronology close -gap that the lack of a 0 years resulted.

honors and awards

Cesare Emiliani was honored by naming the genus Emiliania , which includes the taxon Emiliania huxleyi , which was previously assigned to Coccolithus . He was also honored in 1983 with the Vega Medal of the Swedish Society for Anthropology and Geography and in 1989 with the Alexander Agassiz Medal of the National Academy of Sciences for his isotope studies on foraminifera of plankton from the Pleistocene and Holocene .
