(eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office) 62 https://doi.org/10.2973/dsdp.proc.62.134.1981 781-783 Study of 12 carbonate oozes from Deep Sea Drilling Project Hole 463, in the Mid-Pacific Mountains, suggests mean values of 0.70690 ± 0.00029 (2-sigma) and 0.70712 ± 0.00030 (relative to 0.71014 for the NBS 987 Sr isotope standard) as representing the Sr isotope composition of the Barremian and early Aptian seas, respectively. Two additional values of less than 0.7064 are the least radiogenic values known from the Phanerozoic and may be a consequence of the introduction of Sr depleted in the heavy isotope from massive submarine volcanic activity, which followed the initiation of the latest oceanic spreading episode in the Oxfordian. 174.6678 174.6678 21.3502 21.3502 174.6678 21.3502 1978-08-02T00:00:00 1978-08-02T00:00:00 613.9 813.0 not specified DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 62-463 21.3502 174.6678 North Pacific/SEAMOUNT -2525.0 1978-08-02T00:00:00 Leg62 Leg62 1978-07-29T00:00:00 1978-07-29 1978-09-07T00:00:00 1978-09-07 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Thiede, Jörn Thiede, Jörn Vallier, Tracy L Vallier, Tracy L doi:10.2973/dsdp.proc.62.1981 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 822.5 m 305.5 m 92 cores; 820.5 m cored; 0 m drilled; 37.2 % recovery 48 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 Clauer Norbert Sample label Stage Stage Clauer Norbert Stage 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] Strontium-87/Strontium-86 ratio 87Sr/86Sr strontium-87 87Sr strontium-86 86Sr https://en.wikipedia.org/wiki/Isotopes_of_strontium ratio see reference(s) Clauer Norbert 87Sr/86Sr Strontium-87/Strontium-86 ratio, error 87Sr/86Sr e ± strontium-87 87Sr strontium-86 86Sr https://en.wikipedia.org/wiki/Isotopes_of_strontium see reference(s) Clauer Norbert 2-sigma/root(N) 87Sr/86Sr e [±] supplement citable author33056 basis12 campaign184 campaign3374925 event12678 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 inst41 license101 method10974 method174 method5059 param1666 param21197 param6099 param790 pi33056 project4 ref60498 term1073131 term20775 term2663825 term38263 term40739 term41056 term43863 term44325 topotype1
