While the Observatory neglects no

avenue that might furnish a clue tothe answers, it emphasizes oceanograph-ic and ocean-bottom studies for severalreasons. The oceans cover more than70 percent of the earth's surface, anduntil the last quarter-century, that area

has been all but neglected scientifically.Much of the present land surface, in-cluding most mountains, is covered bymarine sediments. Similar sediments are

continuously being deposited on the bot-tom of the sea, and what may be futureland is now being developed.The Observatory operates research

vessels in this phase of the program.The famed veteran, Vema, which hastraversed all of the oceans of the globe,is now on her 24th scientific voyage.The Conrad is on the 11th voyage inthe service of Lamont.Aboard these ships, instruments

(many of them designed and built atLamont) are used to measure the mag-netic and gravitational fields, to makeprecision soundings, for seismic reflec-tion and refraction determinations ofthe nature of materials beneath theocean floor, for photographing the bot-tom of the sea, for determining the flowof heat through the ocean floor, and forstudying the propagation of sound inthe seas.

One of the important tasks at sea

is the taking of cores of deep-sea sedi-ment that has been laid down on theocean beds by nature and has re-

mained there undisturbed for ages. Toa scientist studying the history of theglobe, these sedimentary layers are likepages in a book. Several thousand cores

percent of the scientific papers werepresented by Lamont staff members andstudents. At the April 1967 meetingof the Union the number of papers pre-sented by the Observatory personnelgrew to 8 percent, and were presentedin each of the disciplines covered bythe Union.The Lamont estate had four build-

ings and four residences, including theLamont mansion, when Columbia re-ceived the property. In a very shorttime the mansion proved to be inade-quLate for all the personnel and equip-ment, and the Observatory embarked ona building program that brought thenumber of buildings to twelve and thenumber of residences to five. Plans areunderway for the graduate section ofthe Geology Department of ColumbtiaUniversity to move to the Lamont cam-pus.

The Lamont Geological Observatoryhas been able to carry on the majorportion of its research and developmentwork through contractual arrangementswith grants from United States govern-

earned an enviable reputation withgovernment agencies for the worthwhileresults obtained for them from its re-search and related activities-activitiesperformed efficiently and at the mini-mum cost.The magnitude and scope of this

highly desirable research work at La-mont has been expanding year by yearas more and more interest has beendirected toward oceanographic andplanetary matters.
