Michael John Keen (born January 1, 1935 in Seaford (Sussex) , † January 8, 1991 in Halifax (Nova Scotia) ) was a Canadian marine geologist.

Life

Keen grew up in London and studied geology in Oxford and Cambridge (from 1957), where he turned to marine geophysics (paleomagnetic measurements in sediment cores in the East Atlantic). When Canada started a large marine research program in the early 1960s, Keen went there. He was from 1961 Assistant Professor at the Institute of Oceanography and 1969 Professor and Head of the Faculty of Geology at Dalhousie University and 1977 to 1988 Director of the Atlantic Geoscience Center (AGC) of the Geological Survey of Canada in Dartmouth (Nova Scotia) . After that he was a senior scientist there. He died of a heart attack after jogging.

In Dalhousie he first undertook marine geological trips to seismically measure the thickness of the earth's crust in the Atlantic shelf of Canada. He also created seismic profiles through the northern, submarine end of the Appalachian Mountains in Canada (also on land in Newfoundland in the 1980s). He was involved in the Deep Sea Drilling Project in the Azores, Bermuda and Iceland. Later at the AGC, an important area of ​​responsibility was to ensure the national sovereignty of Canada over these areas by exploring the offshore areas, another area was the deep-seismic exploration of the shelf subsurface. Keen dealt with the geochemistry of basalts from ancient oceanic crust and clues that resulted from it on the depth of the sea at the formation.

In 1986 he received the Logan Medal . 1974/75 he was President of the Geological Association of Canada. 1981 to 1983 he was President of the Canadian Geophysical Union. In 1974 he became a Fellow of the Royal Society of Canada .

The Geological Association of Canada awards him the Michael J. Keen Medal for marine geologists in his honor.

He was a hobby mountaineer. In 1963 he married the marine geologist Charlotte Davidson (quoted before the marriage CE Davidson, afterwards CE Keen), with whom he also published a lot, even after the divorce in 1972. In 1977 he married the geologist Susan Atkinson, with whom he had three children.
