Lamont–Doherty Earth Observatory

(Redirected from Lamont Doherty Earth Observatory)

The Lamont-Doherty Earth Observatory (LDEO) is a research institution specializing in the Earth science and climate change. Though part of Columbia University, it is located on a separate closed campus in Palisades, New York.[2]

The Observatory was one of the centers of research that led to the development of the theory of Plate Tectonics as well as many other notable scientific developments.

Campus

edit

LDEO is located in Palisades, New York on a property overlooking the Hudson River which was once the weekend residence of banker Thomas W. Lamont. It was donated to the university in 1948 by his widow, Florence Lamont.[2] In 1969, the Observatory was renamed "Lamont-Doherty" following a gift from the Henry L. and Grace Doherty Charitable Foundation.[3]

Climate change

edit

The LDEO is a substantial source of data for the US government in relation to climate change. Faculty at the LDEO have been noted for giving climate change testimony to Congress in relation to melting ice sheets.[4] NOAA has also noted the LDEO's Global Ocean Surface Water Partial Pressure of CO2 Database as being an instrumental source of partial pressure carbon dioxide data (pCO2), which can, in turn, detail the amount of carbon dioxide dissolved in the earth's oceans. Many versions of the LDEO database have been published over the years, dating back to 2006.[5]

Tree rings

edit

The tree-ring lab at the LDEO studies the effects on climate and climate change on trees. In an interview, Nicole Davi from the LDEO noted findings like the formation of tree-rings during extended dry seasons, as well as work being done to carbon-date trees to verify tree ring data.[6]

Core repository

edit

The core repository at the LDEO stores various drilled sediment samples from the earth's oceans. The samples have been used to detail climate changes between glaciation periods, in context of dissolved elements and gases, like calcium (from shells) and carbon dioxide.[7]

Earthquakes

edit

A major source of past earthquake data comes from the Lamont-Doherty Earth Observatory/National Center for Earthquake Engineering Research (NCEER) Earthquake Strong Motion Database.[8]

Antarctic mapping

edit

In 2012, Voice of America documented the work done by LDEO researcher Robin Bell, and others, in mapping the land underneath the Antarctica ice sheet. Several notable findings included the discovery of hidden rivers, hidden mountain ranges, and significant geothermal energy below the ice.[9]

Research vessels

The RV Marcus G. Langseth
This paragraph is an excerpt from RV Marcus G. Langseth.[edit]
RV Marcus Langseth is a research vessel operated by the Lamont–Doherty Earth Observatory (LDEO) of Columbia University as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet.[25][26] The Marcus G. Langseth was dedicated on December 4, 2007, came into service in early 2008, replacing the RV Maurice Ewing.[27]

The R/V Marcus G. Langseth, owned by the U.S. National Science Foundation, will generate CAT-scan-like 3D images of magma chambers, faults and other structures miles below the world's seabeds. To be used by dozens of cooperating institutions, it will be operated for NSF by Columbia University's Lamont–Doherty Earth Observatory.
