(eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office) 72 https://doi.org/10.2973/dsdp.proc.72.125.1983 577-579 Compressional-wave velocities were measured in 9 samples from the 18 m of igneous basement penetrated by drilling at Hole 516F. Wet-bulk densities range from 2.50 to 2.92 g/cm**3; compressional-wave velocities (measured at 0.4 kbar confining pressure) range from 4.29 to 6.32 km/s. Because of progressive alteration, compressional-wave velocities in deep-sea basalts tend to decrease with age; velocities in basalts from immediately beneath the sediment/basement contact are consistent with the proposed age (86 ± 4 Ma) of basement at the site. A very strong vertical velocity gradient of 0.126 km/s/m in the 18-m basement interval reflects a marked decrease in the degree of alteration with depth beneath the contact. -35.285 -35.285 -30.2765 -30.2765 -35.285 -30.2765 1980-03-11T00:00:00 1980-03-11T00:00:00 1.8 15.9 not specified DSDP Deep Sea Drilling Project https://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 72-516F -30.2765 -35.285 South Atlantic/CONT RISE -1313.0 1980-03-11T00:00:00 Leg72 Leg72 1980-02-28T00:00:00 1980-02-28 1980-04-05T00:00:00 1980-04-05 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Barker, Peter F Barker, Peter F Johnson, David A Johnson, David A Carlson, Richard L Carlson, Richard L doi:10.2973/dsdp.proc.72.1983 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 1270.6 m 690.1 m 127 cores; 1092.5 m cored; 9 m drilled; 63.2 % recovery 90 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Gebhard S N Sample label (DSDP/ODP/IODP sample designation) Density, wet bulk WBD g/cm**3 Density http://dbpedia.org/resource/Density Gebhard S N WBD [g/cm**3] DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length mbsf Depth sed [m] (mbsf) Velocity, compressional wave Vp m/s Velocity http://dbpedia.org/resource/Velocity Linear Velocity http://dbpedia.org/resource/Velocity Pulse transmission technique (Birch, 1960) https://doi.org/10.1029/JZ066i007p02199 Gebhard S N Varying pressure = 0.2 kbar Vp [m/s] (Varying pressure = 0.2 kbar, ...)
